Brilliant Service. Highly Recommend Harry!
I can’t recommend Harry highly enough. He quickly identified some dangerous wiring in my property and had everything safely sorted within two hours. His pricing was very reasonable, and he was incredibly friendly and professional throughout. Harry explained everything clearly as he worked, so I always understood what was happening, which I really appreciated. He managed to come out to me at short notice, tidied up after, and made the whole experience completely stress‑free. I would absolutely recommend Harry to anyone needing an electrician.Verified reviewerJob location: E17RLisa P10 Electric Sockets
