What areas does Brennan EFS cover?
Brennan EFS is based in Laois and takes work across the county, including Portlaoise, Portarlington, Abbeyleix, Mountmellick, Mountrath, Rathdowney and Stradbally. Most installers cover their whole county rather than one town, so it is worth confirming your own address when you call.
Should anything be done before the installation?
Insulation comes first on any home energy upgrade. A well-sealed house needs a smaller system and runs at a lower cost, and attic and wall insulation carry SEAI grants of their own. Ask about the fabric of the house when you speak to Brennan EFS.
What grant can I claim on work by Brennan EFS?
Because they are on the SEAI register, work carried out by Brennan EFS is grant-eligible. SEAI pays up to €1,800 for solar panels as of July 2026. The installer applies on your behalf and you pay the balance after the grant is deducted.
Does my home in Laois qualify for a grant?
A home built and occupied before 2021 usually qualifies. Housing across Laois varies a lot, so the survey decides rather than the county. A registered installer confirms eligibility during a free survey before anything is committed.
