Excellent service

Verified Review

Very grateful to Coslec Electrical services for coming to my property at short notice to check the electrical requirements for a new hob and cooker. They determined quickly that what I had was sufficient saving me money by not getting work done that the supplier had said was necessary for installation.

I wish I had met Carl at the very start of the renovation project: he was polite, thorough, methodical, very knowledgeable about his field, and very pleasant to chat to. At every stage he was professional: always keeping me updated, prompt in responding to queries/ concerns, and respectful of the environment he was working in. I have no hesitation in recommending him to anyone and will no doubt call on his services again. Top marks and 5 stars!
