One home. One plan. One upgrade path.

What is a whole home retrofit?

A full home energy retrofit upgrades your home’s insulation, heating, ventilation and energy systems to modern standards — in one coordinated project. You get lower energy bills, a warmer home, and access to SEAI-backed grants of up to €25,000 under the One Stop Shop scheme.

What’s included in a full retrofit?

  • Attic, cavity, internal or external wall insulation
  • Advanced heating controls and zoning
  • Airtightness upgrades and ventilation (natural or mechanical)
  • Solar PV system for renewable electricity
  • Air to Water heat pump (optional, if BER target allows)
  • BER before & after, plus SEAI paperwork & coordination

We build your retrofit around insulation first — then support it with heating and renewables.

Insulation Grants
  • Up to €25,000 in Grants

    SEAI One Stop Shop covers 45–51% of eligible retrofit costs

  • One Project, One Team

    We coordinate all survey, install, grant and BER work

  • Insulation-First Strategy

    We prioritise core upgrades before optional technologies

Who qualifies for One Stop Shop support?

Grant eligibility made simple

To access SEAI’s One Stop Shop grants, your home must:

  • Be built before 2011
  • Have a BER of B3 or lower before work begins
  • Achieve a BER of B2 or better after the retrofit

Premier Insulations works with SEAI-approved partners and technical advisors to ensure your upgrade is compliant and grant-ready.

What customers say

“We did a full retrofit — attic and wall insulation, new controls, ventilation, and solar. Premier handled everything and the house is completely transformed.”
— D. Lawlor, Meath

“Our BER jumped from E2 to A3. Heating bills cut in half. The grant made a huge difference and the whole process was easier than expected.”
— R. Keegan, Mayo

How the process works

  1. Book your initial energy survey
  2. We inspect, assess and plan the upgrades to meet BER targets
  3. We help with SEAI grant paperwork and technical documents
  4. Our team installs insulation, controls, solar or heat pump (as needed)
  5. Post-works BER carried out and submitted to SEAI

We handle everything — you deal with one trusted team from start to finish.

We cover all 32 counties

Whether you’re in Louth or Limerick, Galway or Wexford — we have trained crews ready to handle full insulation-led retrofits with minimal disruption. We’ve done over 10,000 jobs across Ireland and work with local surveyors who understand your housing type.

Retrofitting on a budget?

You don’t need to do everything at once. Many clients start with insulation and controls, then add heat pumps or solar later. We’ll help you build a step-by-step plan that meets SEAI targets and makes sense for your home.

Quick answers

What is a whole home retrofit?

A full upgrade to your home’s insulation, heating and energy systems to achieve a high BER rating and lower running costs — with SEAI grant support.

What’s included?

Insulation (attic, walls), heating controls, ventilation, solar PV and heat pumps — depending on your home’s condition and grant goals.

Is this different from Better Energy Homes grants?

Yes — this is the One Stop Shop scheme. It supports full upgrades in one project and requires achieving a BER of B2 or better.

Do you handle the paperwork?

Yes — we manage all grant forms, technical requirements and SEAI submissions.

Can I phase the upgrades?

Yes — we can build a plan that gets you to B2 over time if needed. You may start with insulation and add technologies later.
