Gas & Electrical Safety Certificate

Very helpful staff over the phone and also on the day of the engineer's visit the guy was really friendly. The price that was quoted on the phone was the same as price we ended up paying so no extra charges. Didn't take as long as we thought and the guy seemed to know what he was doing. For the amount of service the price was more than reasonable. Recommend to everyone and will use in the future.
