Amazing experience and professional and experienced. Would recommend.
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
DA Electrical resolved our plumbing issues when fitting our bathroom. Included new pipework as well as connections. Neat tidy work and very considerate, kept us informed every step of the way. Pleased they did the electrics and plumbing. Highly recommended
DA Electrical replaced our old fuse board and sorted the wiring in our flat in Walthamstow. Turned up on time, explained everything clearly, and left the place spotless. Fully certified and a fair price — wouldn't hesitate to recommend them
Easy communication and clear information about costs. Very polite and completed the job to our satisfaction. Thank you!
