I recently had a new boiler installed by the Top Plumb team and wanted to write because they got me out of a spot of bother and did an excellent job. I called up because our boiler failed and we had no hot water, making bathing my 2 year old son a nightmare. Noting that it was urgent, they shifted some things around in their schedule and came within 2 days. The guys turned up (and team of 3) as promised at 0800, worked their socks off all day, and the job was completed by 1800 that day.
Not only were the guys thoroughly professional, but they did a first class job for what I regard as a very competitive price.
So impressed was I that I've called Top Plumb a couple of times since then, for much smaller jobs. Again, the service has been first class, even though one job only cost me £40.
I was recommended Top Plumb by my neighbour, and I would highly recommend them to anyone looking for a plumber or heating engineer. Andy and Kev both really know their stuff and have looked after me really well.
