One Stop Shop

To start the process a homeowner contacts a One Stop Shop from a list of SEAI registered providers. They will assess your home to determine if enough improvements are possible to qualify for the scheme and advise on what options are best suited.

They will manage the entire project from start to finish, including all of the construction work and follow-up paperwork.

With the One Stop Shop, the grant value is deducted from the upfront cost of the insulation or other home improvements. This means that homeowners know ahead of time exactly how much they will be paying.

Fully Funded Energy Upgrades – Warmer Homes Scheme

This programme covers the entire cost of upgrades such as attic insulation, new doors and windows, and more, for lower income homeowners on certain welfare payments.

The SEAI will then assess the property for appropriate upgrades, appoint a contractor to carry out the works, and after they are completed will carry out a follow up BER Assessment and quality inspection.
