Your one stop shop for deep retrofit projects

Energia Cosy Homes Scheme offers all the practical support and advice you need to retrofit your home and to bring it to the highest level of energy efficiency. Our expert team can help you apply for the widest available range of SEAI home energy upgrade grants, including up to €35,000 per home for deep retrofits.

Our quick and easy energy upgrade calculator offers a detailed breakdown of the potential costs for your home as well as the available SEAI grants.

Benefits of a deep retrofit

A deep retrofit can help bring your home to a high level of energy efficiency. Retrofitting means vastly improving the energy rating of an existing home by upgrading multiple aspects of its structure and energy systems. 

Conducting a deep retrofit will pay for itself over time as you will start to see big savings on the amount of energy you use at home.

What's included in a Deep Retrofit Upgrade?

Insulation upgrades

Attic, Floor, Wall and External Windows and Doors.

Advanced energy upgrades

Air Sourced Heat Pump, Solar PV, Air Tightness Measures, Wood Burning Stove.

End to end project management

Works verified by independent engineers and all building & extension works carried out by our team.

Do I qualify for deep retrofit grant funding?

Was your home:

Built and occupied before 2011 for insulation, heating controls and renewable systems grants

Does your home:

Have an existing BER of D2 or lower and achieve at least a BER of B2 on work completion.

Your home:

Has not previously received grants for the same home energy upgrades

How do deep retrofit projects work?

Homeowners can choose the best energy upgrade for their home and view the cash amount that the SEAI & Energia will contribute towards the cost of the upgrade. Ordinarily, homeowners would have to pay for all work and claim back the grants at a later date. The benefits of upgrading your home with Energia are:

  • We discount the deep retrofit grant up-front, so you do not have to wait for the grant
  • We carry out all works, not just one or two measures
  • We organise the BER for you
  • We hold the highest level of insurances
  • We are members of the Construction Industry Register of Ireland
  • We are a member of the Irish Green Building Council
  • We are members of the Micro Renewable Energy Federation and the Construction Industry Federation

We'll manage the entire process for you:

Phase 1: The initial assessment

of your home

Phase 2: Full project management

of the works

Phase 3: All SEAI grant application

& new BER paperwork
