The Deep Retrofit Pilot programme is available to all Service Providers who demonstrate the skills and capacity to deliver deep retrofit projects in the application process.

Funding for the pilot programme

Reflecting governments multi-annual commitment of funding, the National Mitigation Plan commits a total of €21.2m between 2017 and 2019 with an additional €5 million in 2019 to support this Deep Retrofit grant.

SEAI will fund up to 50% of the total capital costs and project management costs combined. Funding will be provided to projects which demonstrate an integrated, comprehensive strategy for significantly improving home energy performance.

We will fund up to 95% for voluntary housing association homes and the homes of those that are in energy poverty (based on the eligibility criteria). This is only available as part of a wider project that includes homes not in energy poverty. The energy poverty component must make up no more than 25% of the total number of homes in each project.

We aim to maximise learnings by funding projects supporting
  • A range of building archetypes
  • Development toward large scale deployment
  • Regulatory development
  • Multiple customer benefits
  • Financial innovation

SEAI are currently inviting pilot projects for 2019 delivery. The deadline for completion of projects approved for 2019 delivery is 11th October 2019. It is important that the project timelines in applications are realistic and indicate projects can be completed by the deadline.

Interim payments require you to submit monthly progress reports and other specified deliverables. These will be outlined in your contract.


As described in the Guidelines, data monitoring is a key part of the project for SEAI in order to understand the experiences of homeowners, energy consumption of the home and heating technologies, amongst other things. Consent forms will be issued with Letters of Offer but it is important that the homeowner understands that SEAI respects and will protect their data. Top this end, please direct homeowners to this Privacy Notice.

Interim payments require you to submit monthly progress reports and other specified deliverables. These will be outlined in your contract.


Payments are made at specific milestones, e.g. 50% completion, and when the works have been signed off by the Inspections Unit as being completed.

The following payment guide is designed to provide clear instructions on what is required to submit a grant claim. It is important to note that all grant payments are made on a reimbursement basis. SEAI will reimburse the grant amount once all relevant documentation has been submitted.

Value for money

The project’s value for money will be assessed in terms of energy savings relative to the cost of and the representation of the target market.

Technical proposal

We are looking for projects offering a whole house solution with a fabric first approach. Projects with potential solutions for a large part of the deep retrofit target market are preferred.

Quality and delivery

The proposed delivery of the project will be assessed. This includes how it will ensure that the full value of the project is realised for the customer.

The full criteria are available in the application guide.

SEAI National Deep Retrofit Conference

We held our inaugural National Deep Retrofit Conference in June 2017 at the Aviva Stadium. The conference brought together key stakeholders including building design and construction professionals, financiers, Local Authorities and policy makers. We followed up in June 2018 with our second conference which focused on the learnings from year one of the pilot programme in Ireland.
