What these register snapshots tell you

Service areas can cover several counties. A listing here does not mean the business is based in your county, is a HomeGrants partner, or is taking new work. Confirm the business, its current registration for the specific work and its availability before agreeing a job.

• Better Energy Homes: Snapshot copied 29 September 2026. Check the current SEAI Better Energy Homes register.

For Better Energy Homes, county coverage comes from the register’s regional Serviced Areas and each count uses its named measures. Solar PV uses domestic company listings and their published serving counties. One Stop Shops are counted separately using their published service counties. A business may appear in several sections or counties, so the counts must not be added together as a total of businesses.

We show up to six examples with a usable website per section, alphabetically by business name. We are not paid for these listings. Presence or absence in a sample says nothing about the quality of a firm’s work. No individual contractor was rechecked as part of this page’s editorial update.
