How Kildare compares with the other counties
Each job's count against the median county's. Published figure
378 heat pump installers say they work in Kildare; the median county has 279
Kildare is 1st of 26 for heat pumps and 1st for companies of every kind. 103 are based here, 6th of 26.
Each bar is Kildare'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.
