Review by Robert

"I run three properties and several outbuildings. Alex has helped us update our antiquated electrical system. Including new consumer units, lighting and installation external security lights and power outlets. He is always on time, if not early and has never missed a day. He takes all rubbish away and leaves the site clean and tidy. Of all the trades I have used I can rely on Alex the most."
