"Power went out at 11pm on a Wednesday. Called these and the electrician was here in 40 minutes. Faulty breaker, replaced on the spot. Back on within the hour."
"Had the house rewired last month. Dreaded it, but they planned the routes so well there was barely any mess. Plastering was minimal. Really impressed with the finish."
"Got an EV charger installed. Surveyed on Monday, fitted on Wednesday. Works perfectly with the app. Straightforward from start to finish."
