“We are a Charity and as such we need to watch our pennies and ensure value for money. We use Gas Mark One to service our boiler and complete other heating related work at our offices in Abergavenny. This is because we know from experience that we will get the work completed within the time stated, the work will be of high quality and we will not be charged the earth. I have found the engineer who has visited to be very helpful, knowledgeable and willing to go that extra mile to keep us warm and safe.”

Chris Bowie
