I was looking to make space and put all the hot water things in the loft along with fitting some new radiators and installing a Nest system. Really exceptional service, they: - turned up to quote the day after my initial enquiry - provided a really detailed quotation for materials and labour - had everything done in three days - solved problems on the go (and kept me informed) - fitted floor protection to all areas during the works - helped me save money on certain products I had requested - cleared up each night - fitted a temp supply to keep the water running All in all the solution they provided is vary economical on space with neat pipework and everything labelled. As I was working when they finished the works they also came back at the weekend to teach me how to use it all (which must have involved some patience)! Affordable, professional, hassle free and friendly!

Absolute Top Quality with Top Plumb Hired this company on recommendation of another local plumber who didn't cover my area, and from the initial email with Office staff, Kevin visited and discussed my requirements and gave recommendations. Nothing was too much trouble and all questions were answered honestly and quickly. The quote prepared was in the middle of two others, but as Kevin explained the pros of my boiler and the benefits it would give I decided to hire them. The workmanship from all members who visited my property was 1st class, the carpets were protected from the start and the work done to the highest quality and everything was left clean and tidy on departure. I will be using them again in the future for my annual servicing, as they are a company I would highly recommend to others and the staff know what they are doing and the service top class. Its not always easy to find these days, so keep it up and keep doing what your doing!

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.
