Opinion and feedback on work completed
Customer Service
I used this company to completely re-wire our house. He came round to assess the job and provide a quote, he was very honest in telling us what didn’t need updating and therefore saving us money. The job was completed in 2 days, and we were happy to leave them in our house alone. We have young children so it wasn’t safe environment to remain in with wires etc exposed. I completely trusted his character, his judgment and experience.

Carl came around to the house to replace a number of outdated and tired electrical sockets, and to repair a faulty light fitting. His approach was professional, friendly and efficient, and while here identified other opportunities to bring our house’s electrical supply up to date. We were so impressed, we have lined him up to return and make the improvements very soon. Highly recommended.
