Mechanical & electrical, delivered together

Most building-services problems happen at the joins — where the electrical contractor stops and the mechanical contractor starts. We deliver both, so the interfaces are our responsibility rather than a coordination risk for you.

That means power and lighting alongside pipework, ventilation, heat pumps and plant connections, with one programme, one set of drawings-as-installed and one handover pack.

Used DA to swap out our old fuse board as it was ancient and kept tripping. Lads turned up when they said, got it done in a few hours and left no mess. New unit looks miles better and got all the paperwork through after. Can't fault them
