About us
Dublin electricians since 2010.
Brennan Electrical was founded by Cian Brennan after ten years as a qualified electrician with larger contractors. His view was simple: the quality of the electrical work in Dublin shouldn't depend on how big the contract is. We now run a team of eight RECI-registered engineers across Dublin and Kildare. The standards haven't moved since day one.
