Cork Insulation
A complete insulation and energy upgrade service for Cork
County Cork is Ireland’s largest county, with Cork City, commuter towns, coastal villages and rural farmland. Homes range from older terraces and farmhouses to newer estates and one-off rural builds, so there is a wide mix of insulation levels and heating systems.
Premier Insulations provides a full range of insulation, heating and energy upgrade services for homes and small commercial buildings throughout County Cork. Insulation remains at the core of what we do, with heating, solar and other upgrades planned around it so you get the best comfort and value from your investment.

Heat pumps and solar PV in County Cork
For suitable, well-insulated homes in Cork, we can also help with low-carbon heating and renewable electricity options:
- Air to water heat pumps – modern heat pump systems for homes with good insulation and emitters.
- Solar PV installation – roof-mounted solar panels to generate electricity on site.
These technologies work best when insulation, airtightness and heating controls are already in good shape, so we always look at the whole home first.
Energy upgrades, BER and SEAI grants
Larger upgrade projects often involve several measures together. Our energy upgrade services help you plan and deliver this in a structured way:
- Energy upgrades & retrofit overview
- Home Energy Assessment & BER – assessing your home, identifying heat loss and providing an up-to-date BER.
- Eligibility & process for upgrades – understanding if your home and planned works meet current criteria.
For grants and support schemes, we always follow SEAI’s current rules for homes in the Republic of Ireland:
- Grants overview
- SEAI grants – types & amounts
- Insulation grants
- Heat pump grants
- Solar PV grants
- Heating controls grants
- Warmer Homes Scheme – fully funded energy upgrades for certain eligible homeowners. SEAI runs this scheme and appoints contractors directly; Premier Insulations can advise you and carry out additional works where required.
Premier Insulations is an SEAI-registered contractor for homes in the Republic of Ireland.
SEAI grants are only available for eligible properties in the Republic of Ireland.
Windows and doors as part of your Cork upgrade
Insulation and airtightness are usually the first and most cost-effective steps, but windows and external doors also play an important role in comfort and heat loss. As part of a broader upgrade, we can review the condition of your windows and doors and advise how they fit into your insulation and heating plan.

Can I get SEAI grants for insulation works in Cork?
If your property is in the Republic of Ireland and meets SEAI’s current criteria, you may be able to receive grants for measures such as attic insulation, cavity wall insulation, internal or external wall insulation and heating controls. Premier Insulations is an SEAI-registered contractor for homes in the Republic of Ireland. SEAI grants are only available for eligible properties in the Republic of Ireland.
Do you only do insulation, or can you help with heating and solar as well?
Insulation is our core service, but we also provide heating and boiler services, heating controls, air to water heat pumps for suitable homes, and solar PV installation. On Cork projects, we usually start by improving insulation and airtightness, then make sure the heating and renewables are sized and set up correctly around that.
Can you work on rental properties and small commercial buildings?
Yes. We regularly upgrade insulation and heating in rental homes, small apartment blocks and commercial properties such as offices, shops and small industrial units in County Cork. For commercial projects, we review usage patterns, fabric and services to recommend the most appropriate measures.
How do I get started?
The easiest way to get started is to book a free survey. We will visit your Cork property, assess the existing insulation and heating, discuss your goals and budget, and outline a recommended plan. Where relevant, we will also explain which SEAI grants may apply and how the application process works.
