Deep Retrofit

What is Deep Retrofit?

Deep Retrofit is a government-backed Sustainable Energy Authority of Ireland (SEAI) initiative designed to ensure that energy inefficient houses with  poor BER rating are brought up to a minimum A3 standard.

Qualifying applications are grant-aided to the tune of 50% to 95%, depending on your personal circumstances, and payments are made in three stages. More detailed information about the programme available on SEAI website here.

What is covered?

Deep retrofit works typically include:

  • Attic and external insulation
  • Introducing PV solar panels for electricity
  • A heat pump to replace oil or gas
  • Window and door replacement

Who can apply?

Anyone with a qualifying house can apply but applications must be bundled together in groups of 5.  You can join up with neighbours, family or friends. Local authorities, housing groups and voluntary associations also qualify.

The deadlines are up to June 6, 2018 for group works over €250,000 or July 27 for group works under that threshold.
