One Stop Shop
There is no single figure. A One Stop Shop bundles the grants for all the upgrades your home needs (heat pump, insulation, windows and more) and takes them off your bill upfront, so a full upgrade can be worth tens of thousands in grant support.

What it is
Managed deep retrofit, one contractor handles it all. Your home must reach a BER of at least B, plus either get a heat pump or improve its primary energy use by 100 kWh/m²/yr. The One Stop Shop works out how. A whole-home upgrade can include new windows and doors as part of the works. Homeowners, first-time buyers, private landlords and approved housing bodies can use this route.
Who can get it
- You want a complete home upgrade managed for you, rather than doing measures one at a time
- The upgrade brings your home to a BER of at least B, plus a heat pump or a primary energy improvement of 100 kWh/m²/yr, usually through several measures together
- It suits any home type, from apartments to detached houses, including heritage and traditional homes built before 1940 (homeowners, first-time buyers, private landlords and Approved Housing Bodies can apply, for a home built and occupied before 2011)
- An SEAI registered One Stop Shop handles the lot: the home assessment, the grant application, the contractors, the follow-up BER, and finance support if you need it.
- The grants are taken off the cost upfront, so you pay the balance rather than the full price.
- The average result is a jump from a D2 rating to an A2.
- If a full upgrade is too much at once, you can do the individual grants step by step instead.
