If you live in Ireland and want to lower your home heating bills, the Heating Controls Upgrade Grant is one of the easiest grants you can apply for right now.

The Sustainable Energy Authority of Ireland (SEAI) pays you €700 toward upgrading the heating controls in your home. This grant is part of Ireland’s Better Energy Homes scheme — a government programme that helps homeowners make their homes warmer and cheaper to run.

In simple terms: you upgrade your heating controls, and the government gives you €700 back to help cover the cost.

How Much Is the Heating Controls Grant in 2026?

The SEAI pays a flat grant of €700 for a qualifying heating controls upgrade. This amount has been confirmed and is available as of early 2026 under the Better Energy Homes scheme.

This makes it one of the most affordable and straightforward SEAI grants to claim. You do not need to do a full home retrofit or install a heat pump to get this money. It is a standalone grant you can apply for on its own.

What Does the Grant Cover?

To qualify for the full €700, your upgrade must include all four of the following:

1. A room thermostat (or wireless programmable thermostat) — lets you set the temperature you want in your home
2. Thermostatic Radiator Valves (TRVs) — fitted to each radiator, these control how warm each individual room gets
3. A time clock or programmer — lets you set exact times for your heating to turn on and off
4. Zone controls — lets you heat different parts of the house (for example, upstairs and downstairs) separately

All four of these items must be installed together for the upgrade to qualify. You cannot claim the grant for just one or two of them.

Who Can Apply for the Heating Controls Grant?

The heating controls grant is open to:

• Homeowners in Ireland with a property built and occupied before 2011
• Landlords — yes, landlords qualify too, as long as the property was built and occupied before 2011

The grant applies to all property types, including:

• Detached houses
• Semi-detached houses
• Terraced houses
• Apartments

Important: You are not eligible for this grant if you are applying for — or have previously received — a heat pump grant from SEAI for the same property.

Why Should You Upgrade Your Heating Controls?

Many Irish homes waste a lot of energy because their heating systems are old and uncontrolled. A boiler without proper controls runs longer than it needs to and heats rooms that nobody is using.

Upgrading your heating controls can:

• Cut your heating bills by stopping wasted heat
• Make your home more comfortable by keeping temperatures steady
• Reduce your carbon footprint by burning less gas or oil
• Improve your home’s BER (Building Energy Rating) — useful if you ever sell or rent your home

You can also heat your hot water separately from your central heating once zone controls are fitted — so you are not heating the whole house just to get a hot shower.

How to Apply for the Heating Controls Upgrade Grant

Applying is straightforward. Follow these steps:

Step 1: Choose Your Upgrade

Decide you want heating controls as your upgrade. You can combine this with other SEAI grants (like attic insulation or wall insulation) if you wish.

Step 2: Get Quotes

Contact SEAI-registered contractors and ask for quotes. You must use an SEAI-registered contractor — the work will not qualify if done by someone not on the SEAI register.

Step 3: Apply Online

Go to seai.ie and apply online for the grant before any work begins. Do not start the work first — SEAI will not pay a grant for work that was done before the application was approved.

Step 4: Get Your Approval

Your application should be approved quickly — often within minutes online. SEAI will send you a letter of offer. You then have 30 days to accept the offer, and 8 months from the offer date to complete the work and draw down the grant.

Step 5: Complete the Work

Have your SEAI-registered contractor complete the heating controls installation.

Step 6: Get Paid

Submit your payment forms to SEAI. The €700 is paid directly to you after the work is done.

Alternatively, you can go through a One Stop Shop — an SEAI-approved provider who manages the whole process from start to finish. In this case, the grant is deducted from your bill upfront, so you never have to handle the paperwork yourself.

How Much Will the Full Job Cost?

The typical cost to install a full set of heating controls (including a thermostat, TRVs, a time clock, and zone controls) can vary depending on your home’s size and the contractor you choose. However, larger homes generally require more extensive work and additional components, which can increase the overall cost. In addition, installation rates may differ between contractors based on their experience and location.

Therefore, it is a good idea to obtain several quotes before making a decision. By comparing options, you can find the best balance between cost and quality while ensuring the system meets your home’s heating needs.However, the €700 grant takes a meaningful chunk off the bill, and heating controls installations are generally one of the most affordable energy upgrades available.

According to SEAI data, heating controls are among the cheapest starting points for any home energy upgrade in Ireland.

Can I Combine This With Other SEAI Grants?

Yes. The heating controls grant can be combined with many other SEAI Better Energy Homes grants, including:

• Attic insulation — up to €2,000 (or €2,500 for first-time buyers and welfare recipients)
• Wall insulation — for cavity or external walls
• Solar PV panels — for generating your own electricity
• Windows and doors — new from March 2026
• Heat pump grant — up to €12,500 (note: if you claim the heat pump grant, you cannot also claim the heating controls grant for the same property)

Combining grants lets you tackle multiple upgrades at once and get the maximum benefit for your home.

Frequently Asked Questions (FAQs)

Q: Can I apply for the heating controls grant as a landlord? Yes. Landlords can apply for the heating controls grant as long as the property was built and occupied before 2011.

Q: Do I need to get the work done before I apply? No. You must apply and get approval before the work starts. Work done before approval will not be covered.

Q: How long does SEAI take to approve the application? Online applications are often approved within minutes. Postal applications typically take about 5 working days.

Q: Is the grant available in Dublin, Cork, Galway and other areas? Yes. The SEAI heating controls grant is available nationwide across all of Ireland — including Dublin, Cork, Galway, Limerick, Waterford, and rural areas.

Q: What if I already have a heat pump? If you have already claimed a heat pump grant for your property, you cannot also claim the heating controls grant for the same home.

Q: Can I do the work myself? No. The work must be carried out by an SEAI-registered contractor. DIY installation does not qualify.

Quick Summary: Heating Controls Grant 2026 at a Glance

Conclusion

The Heating Controls Upgrade Grant is one of the simplest and quickest SEAI grants to access in Ireland in 2026. At €700, it is not the biggest grant available, but for homeowners not yet ready for a full heat pump installation, it is a practical and cost-effective first step toward a warmer, cheaper-to-run home.

If you have an older oil or gas boiler and your heating controls are outdated, this grant can make an immediate difference to your comfort and your bills — and it takes only a few minutes to apply online at seai.ie.

If your home feels cold in winter and your heating bills keep going up, pumped cavity wall insulation could be one of the best things you can do. It is quick to install, it does not cause much disruption, and it can save you hundreds of euro every year. In 2026, Irish homeowners also have access to bigger SEAI grants than ever before.

This guide explains everything clearly — what pumped cavity wall insulation price is,  what grants you can get, and how to get started.

What Is Pumped Cavity Wall Insulation?

Most Irish homes built after the 1930s have cavity walls. This means that external walls contain two layers of brick or block with an empty gap—known as a cavity—between them.

The cavity was originally designed to prevent rainwater from entering the home, but it also allows significant heat loss. In many cases, uninsulated walls cause up to 30% of a home’s heat loss. Filling the cavity with insulation material reduces heat loss and improves energy efficiency.

During installation, a qualified installer drills small holes into the external walls. The installer then injects insulation material into the cavity and seals the holes after finishing the work. In most cases, the installation takes just one day and creates very little disruption or mess inside the home

How Much Does Pumped Cavity Wall Insulation Cost in Ireland in 2026?

The price depends mainly on the size of your home — larger homes have more wall area to fill. Here is a breakdown of typical costs before any SEAI grants:

On a per-square-metre basis, pumped cavity wall insulation typically costs between €7 and €13 per m² installed, including materials and labour.

SEAI Grants for Cavity Wall Insulation in Ireland 2026

The Sustainable Energy Authority of Ireland (SEAI) offers grants to help homeowners pay for insulation. These grants were increased in February 2026 and now cover around 80% of the average cost for most homes.

To qualify for the SEAI grant, your home must have been built and occupied before 2011. All work must be carried out by an SEAI-registered contractor, and you must get grant approval before any work starts.

From March 2026, there is also a new rule: if you already had cavity wall insulation done with a previous SEAI grant, you can now apply for a second wall insulation measure such as external wall insulation. This is useful if the original fill has settled or if you want to improve your energy rating further.

What Affects the Price of Pumped Cavity Wall Insulation?

Not every home costs the same to insulate. Here are the main factors that can push the price up or down:

How Much Will You Save on Heating Bills?

Based on SEAI data from Irish homes, cavity wall insulation typically saves homeowners between €200 and €400 per year on heating bills. The exact saving depends on your heating system, fuel type, and how warm you keep your home.

After the grant, many homeowners in Ireland pay back their investment in just a few years through lower heating bills. And if you pay little or nothing after the grant, the savings start right away.

How to Apply for the SEAI Grant in Ireland

The process is straightforward. Here is how it works step by step:

1. Check eligibility— Make sure your home was built before 2011 and that your walls are suitable. You can check on the SEAI website atseai.ie.
2. Choose an SEAI-registered installer— You must use a contractor on the SEAI register. Never begin work before getting grant approval, or you will lose the grant.
3. Apply online— Submit your application onseai.iebefore any work starts. The process is straightforward and usually takes a few days.
4. Get a cavity survey— Your installer will check your walls are suitable for insulation. This is a standard part of the process.
5. Installation day— The installer usually completes the job in one day. They drill small holes, pump in the insulation, and seal up the holes.
6. Claim your grant— After the work is done, the grant is paid out. Your installer will often handle the paperwork for you.

Is My Home Suitable for Pumped Cavity Wall Insulation?

Most Irish homes built between the 1930s and the early 2000s have cavity walls and are suitable for this type of insulation. Homes built before the 1930s usually have solid walls and are not suitable.

Your home may not be suitable if:

• The cavity is already filled
• There is significant damp in the walls
• The property is in a very exposed, high-rainfall location
• The walls are not in good condition

A professional installer will inspect your walls before starting, so you will know if your home is suitable before you commit to anything.

What Is Insulated Plasterboard?

Insulated plasterboard is a two-in-one building product. It combines a layer of rigid insulation with a standard sheet of plasterboard, all bonded together into one board. In Ireland it is also called a warmboard, thermal board, or dry lining board.

Instead of fitting insulation and plasterboard separately, you fix one board to the wall and the job is done. This saves time, reduces labour costs, and helps your home meet Irish building regulations for thermal performance.

It is used in homes, apartments, offices, and schools across Dublin, Cork, Galway, Limerick, and every other county in Ireland.

How Much Does Insulated Plasterboard Cost in Ireland in 2026?

Prices vary by board type, thickness, and supplier. Here is a simple guide to what you can expect to pay in 2026.

EPS (Expanded Polystyrene) Insulated Plasterboard — Budget Option

They use polystyrene foam bonded to 9.5mm plasterboard and are ideal for window reveals, ceilings, and light internal wall insulation.

• 30mm EPS board: approximately €19 to €25 per board (incl. VAT)
• 40mm EPS board: approximately €25 to €35 per board (incl. VAT)

Brands include Gyproc ThermaLine Basic and Knauf EPS Thermal Laminate.

PIR (Polyisocyanurate) Insulated Plasterboard — Best Performance

PIR boards offer the best thermal performance for their thickness. They use rigid foam insulation bonded to 12.5mm plasterboard and are the most popular choice in Ireland for internal wall insulation on external walls.

Based on current Irish supplier pricing (Goodwins, Tadhg O’Connor, MyBuildingSupplies.ie):

• 27.5mm PIR board: from approximately €46 to €57 per board (incl. VAT)
• 37.5mm PIR board: from approximately €57 to €70 per board (incl. VAT)
• 52.5mm PIR board: from approximately €68 to €88 per board (incl. VAT)
• 62.5mm PIR board: from approximately €79 to €100 per board (incl. VAT)
• 72.5mm PIR board: from approximately €88 to €120 per board (incl. VAT)

All standard boards are 2400mm x 1200mm. Bulk orders attract significant discounts — always ask your supplier for a trade price if buying 10 boards or more.

Brands include Unilin (formerly Xtratherm) Thin-R Thermal Liner, Xtratherm XT/TL, Kingspan K118, and Celotex PL4000.

Moisture-Resistant PIR Insulated Plasterboard — Kitchens & Bathrooms

For wet areas like kitchens, bathrooms, and utility rooms, choose a moisture-resistant (MR) variant. These have a green-faced plasterboard core that resists humidity. Prices are typically 10–15% higher than standard PIR boards.

Quick Answer: What Is the Cheapest Insulated Plasterboard in Ireland?

EPS insulated plasterboard is the cheapest option in Ireland, starting from around €19 to €25 per board (incl. VAT) for a 30mm board. For better performance without a massive price jump, a 27.5mm PIR board starts from around €46 incl. VAT and is the most popular choice among Irish builders and homeowners.

Where to Buy Insulated Plasterboard in Ireland

Several reputable Irish suppliers stock insulated plasterboard for trade and DIY customers:

Goodwins — one of Ireland’s best-known builders’ providers, with competitive daily pricing on Xtratherm PIR warmboards and EPS boards. Available online with nationwide delivery.

Tadhg O’Connor Ltd (TOC) — Munster’s leading building materials stockist with a strong online store. Stocks 50mm and above PIR boards with nationwide delivery. Good for bulk orders.

Brooks — a leading Irish insulation provider stocking a wide range of insulated plasterboards for residential and commercial projects.

MyBuildingSupplies.ie — stocks Unilin (formerly Xtratherm) Thin-R Thermal Liner boards with Eircode-based delivery pricing.

TJ O’Mahony — a nationwide builders’ provider supplying insulated plasterboards to contractors across Ireland, suitable for new builds and refurbishments.

MD O’Shea & Sons — Cork-based supplier with competitive prices and a bulk quote service.

McCarthy’s Homevalue (Waterford) — stocks various thicknesses with online ordering and delivery to Waterford and surrounding areas.

Build4Less / CORE (Dublin) — Dublin-based supplier with free delivery in Dublin on orders over €300 and fast nationwide delivery.

Pro tip: Always get at least three quotes from Irish suppliers. Prices for the same board can vary by 15–20% depending on the stockist and order size.

Types of Insulated Plasterboard — Which One Do You Need?

PIR Insulated Plasterboard The best choice for most Irish homes. PIR insulation has a very low thermal conductivity (around 0.022 W/mK), meaning you get excellent insulation in a thinner board.  Best for external walls, ceilings, and sloped roofs.

EPS Insulated Plasterboard The budget-friendly choice. EPS polystyrene is less efficient per mm than PIR, so you need a thicker board to get the same result. Ideal for window reveals, internal partitions, and ceilings where full thermal performance is not the priority.

Moisture-Resistant Insulated Plasterboard Designed for kitchens, bathrooms, and utility rooms. The plasterboard core resists moisture and helps prevent damp — a key concern in Ireland’s wet climate.

Acoustic Insulated Plasterboard Combines thermal insulation with soundproofing. Useful for homes near busy roads, apartment conversions, or rooms that need both heat retention and noise reduction.

SEAI Grants for Insulated Plasterboard Installations in Ireland 2026

Installing insulated plasterboard as part of internal wall insulation (also called dry lining) may qualify you for an SEAI Better Energy Homes grant in 2026.

Current grant amounts for internal wall insulation (dry lining) as of 2026:

• Detached house: up to €4,500
• Semi-detached or end-terrace: up to €3,500
• Mid-terrace: up to €2,000
• Apartment: up to €1,500

Before the grant, internal wall insulation (including materials and labour) typically costs €4,095 to €10,532 depending on home size and complexity. After applying the SEAI grant, most homeowners pay between €2,595 and €7,032.

From 2 March 2026, a new rule allows homeowners who already received a cavity wall insulation grant to apply for an internal wall insulation grant as a second wall measure — a significant change that opens up additional savings.

To qualify for the SEAI grant:

• Your home must have been built and occupied before 31 December 2010
• Work must be carried out by an SEAI-registered contractor
• You must apply for and receive grant approval before work starts

Apply at seai.ie or through an approved One Stop Shop contractor.

Is Insulated Plasterboard Worth It in Ireland?

Yes — for most Irish homes, insulated plasterboard is a very cost-effective upgrade.

Ireland’s climate is damp and cool for much of the year. Poorly insulated walls are one of the biggest causes of heat loss in older Irish homes — especially those built before the 1990s with solid block or hollow-block walls where cavity wall insulation is not possible.

Installing insulated plasterboard helps:

• Reduce heat loss through external walls
• Lower your energy bills — less fuel needed to heat the home
• Improve your BER (Building Energy Rating) — useful when selling or renting
• Reduce condensation and damp on cold walls
• Meet Part L of the Irish Building Regulations for thermal performance

The payback period on insulated plasterboard, especially when combined with an SEAI grant, is typically 5 to 10 years through reduced heating bills.

Things to Consider Before Buying

U-Value: This measures how well the board prevents heat loss. A lower U-value means better insulation. In Ireland, building regulations require good thermal performance, so always check this before buying. PIR boards achieve lower U-values in thinner profiles than EPS.

Thickness: Thicker boards insulate better but take up more room. In older Irish homes with small rooms, a high-performance PIR board in a thinner size is often the smarter choice than a thick EPS board.

Fire Rating: Check the fire performance of the board, especially for commercial projects or multi-unit developments. Most reputable brands carry the required certifications.

Installation Method: Most insulated plasterboards are fixed using the dot and dab adhesive method. Some thinner PIR boards can also be mechanically fixed. Always follow the manufacturer’s installation guidelines.

Summary: Insulated Plasterboard Prices Ireland 2026

Prices are indicative for 2024mm x 1200mm boards. Always confirm current pricing with your Irish supplier before ordering.

Conclusion

Insulated plasterboard is one of the smartest and most cost-effective upgrades you can make to an Irish home in 2026. Whether you are doing a full retrofit or just improving one room, it gives you insulation and a finished wall surface in a single product — saving time, money, and hassle compared to fitting them separately.

If your budget is tight, start with an EPS board for ceilings or window reveals. If you are insulating an external wall and want real results, invest in a 52.5mm or 62.5mm PIR board. The higher upfront cost pays back through lower heating bills year after year.

Prices in Ireland range from as little as €19 per board for EPS up to €120 per board for thick PIR, so there is an option for every project size and budget. With SEAI grants covering up to €4,500 for internal wall insulation on a detached home, the net cost of a full dry lining job is more affordable than most homeowners expect.

The steps are simple: choose the right board type for your wall, pick an SEAI-registered contractor, apply for your grant before work starts, and compare at least three quotes from Irish suppliers.

Frequently Asked Questions

1. How many boards of insulated plasterboard do I need for a room? Measure the total wall area you want to cover in square metres (length × height for each wall). Each standard board covers 2.88 m² (2400mm × 1200mm). Divide your total area by 2.88 and add 10% for cuts and waste. For example, a typical Irish sitting room with 20 m² of external wall area needs around 8 boards.

2. Can insulated plasterboard be used on all walls in an Irish home? Yes. It is most commonly fitted on the inner face of solid block or hollow-block external walls — the type found in the majority of Irish homes built before the 1990s where cavity wall insulation is not an option.

3. Will insulated plasterboard improve my BER rating in Ireland? Yes. Reducing heat loss through walls is one of the most effective ways to improve your Building Energy Rating (BER). A better BER makes your home cheaper to heat, more comfortable to live in, and more attractive to buyers or renters. Many Irish homeowners use dry lining with insulated plasterboard specifically to lift their BER before putting their home on the market.

4. Is PIR insulated plasterboard safe to use indoors? Yes. PIR insulated plasterboard from reputable brands like Unilin (Xtratherm), Kingspan, and Celotex meets all relevant Irish and European safety standards. The plasterboard face provides a fire-resistant layer and most products carry the necessary certifications for residential use. Always check the product datasheet and follow the manufacturer’s installation instructions.

5. How long does insulated plasterboard last? When correctly installed, insulated plasterboard has a lifespan of 25 to 40 years or more. The key to long-term performance is correct installation — particularly sealing all joints and preventing moisture from getting behind the boards.

Improving the energy efficiency of your home has become a major priority for many homeowners in Dublin. Rising energy costs, climate goals, and government support have made deep retrofits more popular than ever. In 2026, generous grants are available to help Dublin homeowners upgrade older properties and make them warmer, healthier, and cheaper to run.

What Is a Deep Retrofit?

A deep retrofit is a complete energy upgrade of a home. Unlike simple improvements such as adding attic insulation, a deep retrofit looks at the entire property and upgrades multiple areas at the same time.

A typical deep retrofit may include:

• Attic insulation
• Wall insulation
• Floor insulation
• New windows and doors
• Heat pump installation
• Solar panels
• Improved ventilation systems
• Airtightness improvements
• Heating controls

The goal is to significantly reduce energy consumption and improve the home’s Building Energy Rating (BER). Most deep retrofit projects aim to achieve a BER of B2 or better.

Deep Retrofit Grants Available in Dublin in 2026

The main support for deep retrofits comes through the Sustainable Energy Authority of Ireland (SEAI) One Stop Shop Scheme. This programme allows homeowners to access multiple grants through one managed project. A registered provider handles the assessment, contractors, paperwork, and grant applications.

Many homeowners can receive grant support worth more than €25,000 depending on the size of the property and the upgrades completed.

Who Can Apply?

To qualify for a deep retrofit grant in 2026, homeowners generally need to meet the following requirements:

• The property must be located in Ireland.
• The home must have been built and occupied before 2011.
• The property should usually have a BER of B3 or lower before the retrofit.
• The completed project must achieve a BER of B2 or better.
• The work must be completed through an SEAI-registered One Stop Shop provider.

Both owner-occupiers and landlords can apply under the scheme.

Grant Amounts for Common Upgrades

The exact grant value depends on the property type and the measures installed. Examples of 2026 grant supports include:

• Attic insulation: up to €2,000
• Cavity wall insulation: up to €1,800
• External wall insulation: up to €8,000
• Internal wall insulation: up to €4,500
• Heat pump systems: up to €6,500
• Solar PV systems: around €1,800
• Mechanical ventilation: up to €1,500
• Heating controls: up to €700
• Project management support through the One Stop Shop scheme.

A homeowner completing several upgrades together may receive a combined grant package worth tens of thousands of euro.

Changes to Deep Retrofit Grants in 2026

Several important changes have been introduced in 2026.

One of the biggest updates is the removal of the previous minimum energy improvement requirement for One Stop Shop projects that include a heat pump. This change allows more homes to qualify for grants.

In addition, standalone grants for windows and doors became available in 2026, giving homeowners more flexibility when planning upgrades.

Benefits of a Deep Retrofit

There are many advantages to carrying out a deep retrofit in Dublin.

Lower Energy Bills

A well-insulated home requires less energy for heating and hot water. This can lead to significant savings on electricity, gas, or oil bills.

Better Comfort

Many older Dublin homes suffer from drafts, cold rooms, and uneven temperatures. A deep retrofit helps create a more comfortable living environment throughout the year.

Higher Property Value

Homes with strong BER ratings are increasingly attractive to buyers. An upgraded property may command a higher market value.

Reduced Carbon Emissions

Deep retrofits help reduce greenhouse gas emissions and support Ireland’s climate targets.

Improved Indoor Air Quality

Modern ventilation systems can reduce moisture problems and improve overall air quality within the home.

The One Stop Shop Process

The deep retrofit journey is designed to be straightforward.

Step 1: Home Assessment

A registered provider assesses your home and identifies suitable improvements.

Step 2: Retrofit Plan

A detailed plan is prepared showing the recommended upgrades, estimated costs, and available grants.

Step 3: Grant Application

The One Stop Shop provider manages the grant application process on your behalf.

Step 4: Installation

Approved contractors complete the retrofit works.

Step 5: Final BER Assessment

After completion, a final BER assessment confirms that the required energy rating has been achieved.

Are Deep Retrofits Worth It?

For many Dublin homeowners, the answer is yes. Although the initial investment can be substantial, grants significantly reduce the overall cost. The long-term savings on energy bills, combined with improved comfort and increased property value, often make deep retrofits a worthwhile investment.

However, homeowners should always obtain several quotes and carefully compare costs. Some Irish homeowners have reported that independent contractors can sometimes offer lower prices than managed retrofit packages, while others value the convenience and project management provided by the One Stop Shop route.

Conclusion

Deep retrofit grants in Dublin are helping homeowners transform older properties into energy-efficient, comfortable, and environmentally friendly homes. With grant support often exceeding €25,000 and a simplified application process through the SEAI One Stop Shop Scheme, 2026 is an excellent time to consider a major home energy upgrade. Before starting, homeowners should assess their property’s needs, compare providers, and develop a clear retrofit plan. By taking advantage of available grants, Dublin residents can reduce energy costs, improve comfort, and increase the long-term value of their homes while contributing to a greener Ireland.

FAQs

1. How much can I receive through a deep retrofit grant in Dublin?

The amount you can receive depends on your home’s size, condition, and the upgrades completed. In many cases, homeowners can receive grant support worth more than €25,000 when multiple energy improvements are carried out through the SEAI One Stop Shop Scheme.

2. Do I need a BER assessment before applying for a deep retrofit grant?

Yes. A BER assessment is usually required to determine your home’s current energy performance. This assessment helps identify the upgrades needed to achieve the required energy efficiency standard after the retrofit.

3. Can landlords apply for deep retrofit grants in Ireland?

Yes. Both owner-occupiers and private landlords can apply for eligible deep retrofit grants, provided the property meets the scheme requirements and the work is completed by an approved provider.

4. How long does a deep retrofit project take?

The timeline varies depending on the size and complexity of the project. Most deep retrofits can take anywhere from several weeks to a few months, including the assessment, grant approval, installation work, and final BER certification.

5. Is a deep retrofit worth the investment?

For most homeowners, a deep retrofit is a worthwhile investment. It can significantly reduce energy bills, improve indoor comfort, increase property value, and lower carbon emissions. Government grants also help reduce the overall cost of the upgrades.

The attic insulation grant is money the Irish government gives you to help pay for insulating your attic. It is run by the SEAI — the Sustainable Energy Authority of Ireland. The goal is simple: to help people keep their homes warmer while spending less on heating bills.

In early 2026, the government increased these grants as part of the National Residential Retrofit Plan 2026, which has a total budget of €558 million to help 70,000 homes across Ireland become more energy efficient.

The grant covers roughly 80% of the average cost of attic insulation for most homes. For many people, especially first-time buyers and those on social welfare, the grant can cover the entire bill.

How Much Can You Get?

The amount you receive depends on the type of home you live in. Here are the current 2026 grant amounts:

Who Can Apply?

Most homeowners in Ireland can apply. Here are the basic rules:

• Your home must have been built and occupied before 2011
• You must be the owner of the property (not a renter)
• The work must be carried out by an SEAI-registered contractor
• You must get grant approval before the work starts — not after
• If your existing attic insulation is less than 300mm deep, you can top it up and still get the grant

How to Apply: Step by Step

Of all the home energy upgrades available, attic insulation gives you the best return for your money. Here is why:

• Up to 30% of heat in a home can escape through the roof
• The grant covers up to 80% of the average cost
• Most homeowners save enough on heating bills to pay back the remaining cost within 1–3 years
• Your home will feel noticeably warmer and more comfortable

What About People on Social Welfare?
