I found this company via Which in the first place! I am so happy we did. This is actually the second job they've done for us. Initially they replaced a stopcock which was done quickly and efficiently. The main job we've had done is the installation of a new boiler after the death of our ancient gas heater. We had several quotes and people round to inspect and none did as thorough a job as AB Plumbing. They checked on the pipework, they went into the loft and asked a number of sensible questions. Their processes are tight and liaison with the office staff (particularly Jordan) was great. The quote was fully itemised and we went with the advice they gave us which future proofs us a bit. It was in no way forced upon us, a full range of options was given and I genuinely felt that the decision was ours. On the day of the boiler fitting, the staff arrived promptly and worked hard all day. They were respectful of people and property! Whilst I'm sure they felt it, there was no muttering about having to go up two sets of stairs either! Our house needs a lot of work, which this step is part of, and we were not in any way made to feel uncomfortable. I was particularly surprised and pleased when they cleaned up any mess made by drilling etc. There is a clear audit trail in all communications - people do what they say they're going to and show up when they say they will. I unreservedly recommend this company and will be using them for other renovation work in the future!
