Excellent Job

Called Gareth at 08:00 and he agreed to visit the same day despite being out all day over 100 miles away. Arrived on time as agreed and quickly diagnosed a badly wired thermostat and a faulty fan unit in the central heating boiler. Always polite, obviously capable and willing to follow through by identifying and ordering replacement parts. I would recommend to anyone looking for a reliable, open and capable service.

Excellent Serice would use Gareth again.

I've had to call to use GNB Electrical Services on few occasions and every time they have been great. On both occasions he has given me explanations as to what was going on and why things have failed. Great value for money and turns up when they say are going to. Will definitely use again.
