The team at A & C were great – working out who I could get to check my gas heaters seemed like it was going to be a challenge – but Mark gave me an estimated quote over the phone and explained what might be involved if a gas leak was found – and when they found one, the team worked very hard to get it fixed as soon as possible. the price estimate was on the money and the guy (simon i think) who came out was courteous and explained what was going on throughout. I will definitely will use this company again. Thanks A & C 🙂
