The Deep Retrofit Pilot Grant Programme was launched to investigate the challenges and opportunities of deep retrofit in Ireland. The Programme is now closed. The learnings will inform our approach towards a large scale deep retrofit of Irish homes.

The Deep Retrofit Pilot Programme is now Closed for Applications.

Tackling energy efficiency in older housing

Housing continues to pose one of the greatest energy efficiency challenges in Ireland. A considerable portion of older housing performs poorly when compared with those built to the current building standards. We are now delivering the Deep Retrofit grant to tackle this challenge.

In 2017 SEAI launched the Deep Retrofit multi-annual pilot programme. The programme currently investigates the challenges and opportunities of deep retrofit in Ireland. The learning from this pilot will inform our approach towards a large scale deep retrofit of buildings. Our initial focus is on the residential market.

What does a Deep Retrofit involve?

The Deep Retrofit of a home to an A-rating means getting multiple energy upgrades all at once.

Firstly, you will need to reduce the level of heat loss so that you keep heat in the home for longer. This involves some or all of the following: wall insulation, roof insulation, floor insulation, window upgrades.

The next step is to look at an efficient renewable heating system to support the transition away from fossil fuels. The typical heating system installed on a Deep Retrofit Oilot Project is an air-source heat pump.

It also includes mechanical ventilation to maintain good indoor air quality.

Other renewable energy technologies such as solar water heating panels and solar photovoltaic panels may be appropriate for your home.  

We estimate that a sum of over €35 billion will be required over 35 years to make the existing housing stock low carbon by 2050.

Delivering Deep Retrofit

The Deep Retrofit grant presents a significant market and investment opportunity for early adopters of deep retrofit.

Reflecting governments multi-annual commitment of funding, the National Mitigation Plan commits up to €21.2m between 2017 and 2019 with a budget of €7 million in 2019 to support this Deep Retrofit grant. Learnings from this initial programme will inform the large scale roll-out of deep retrofit with an estimated total market value of over €35 billion.

In order to maximise the learnings from the pilot programme and deliver optimal solutions to homeowners as the programme evolves, applications were required to include a minimum of 5 homes in order to examine the challenges and opportunities for delivery of multiple projects, which will ultimately be required for the transition to 2030 and on to 2050.

Service providers

The list below includes service providers who have delivered or are currently delivering Deep Retrofit projects under the Deep Retrofit Pilot programme. The list is a dynamic list being updated by SEAI to include new service providers who become involved in the delivery of Deep Retrofit Pilot projects during the course of the Pilot programme. The list should not be interpreted as a register of deep retrofit service providers maintained by SEAI, nor as an endorsement by SEAI of any service provider.
