Cork's trusted local experts in energy upgrades, solar installations, and building services CEL Energy started because we'd seen the same problems play out in homes across Cork for years. Homeowners were being left to manage half a dozen different contractors – an electrician here, a plumber there, someone else for insulation – with no one taking responsibility for the whole job.

We heard the same complaints over and over: prices that changed halfway through a job, tradespeople who didn't show up, work that looked finished but still let the heat escape. People were spending money on upgrades that didn't deliver what was promised. So we built something different.

A team that handles everything under one roof – solar panels, insulation, plumbing, the works. One team you deal with, one quote you get, one point of contact from start to finish. Fifteen years and 500+ completed projects later, that approach still drives everything we do.
