980 SEAI-registered contractors say they work in Galway
980 companies on SEAI’s registers say they work in Galway (read 25 September 2026). 149 are based in the county, 813 cover it from elsewhere and 18 are One Stop Shops from elsewhere. Firms often tick a whole province, so the count is regional. Registration is a fact about paperwork, not a review of their work.
A flat block in Countess Markiewicz House, Dublin, not in Galway. Apartments built 1990–2004 are the commonest home sold or let in Galway. We don't have a licensed photo of one taken in Galway yet.

How Galway compares with the other counties
Each job's count against the median county's. Published figure
236 heat pump installers say they work in Galway; the median county has 279
Galway is 20th of 26 for heat pumps and 19th for companies of every kind. 149 are based here, 3rd of 26.
Each bar is Galway's count for that job, on a scale to the county with the most; the tick is the median county. Many firms tick a whole province, so counts move in regional steps, and neighbouring counties often share a step. A count is choice, not capacity.

Before you sign
Four things SEAI tells homeowners to do.
- Wait for your grant approval email before any work starts. SEAI does not pay for work that began before it was approved.
- Get at least three quotes, and check each one covers the same job. The cheapest quote is often the one that leaves something out.
- Check the company is on the register on the day you sign. Companies join and leave it, and this page is a copy taken on one day.
- Get it in writing: what is being done, what it costs, when it starts and when it is finished.
