10 Electric radiator installation
Posted 5 days ago
Garry installed an electric radiator in my living room. Punctual and completed the job with minimum fuss, cleaned up the (minimal) mess afterwards. And very competitively priced, too. I am a repeat customer of this firm over the last 2 years, and now wouldn’t use anyone else for an electrical job in my home.Verified reviewerJob location: GU2110 Gary goes above and beyond

This was a difficult job to diagnose being both mechanical failure and electric which is unusual. The impact of this was a two hour investigation and repair involving both a mechanical system and the electronic failure.Verified reviewerJob location: GU2210 Outdoor fountain electrical supply

Mr. Markham arrived on time to replace the two light fittings. I am very pleased with the work and as on previous occasions there was no mess whatsoever. I would have no hesitation in recommending him, and indeed have already done so, to a friend who commented upon the new kitchen light.Verified reviewerJob location: GU2210 LED LIGHTING
