Great team of guys, excellent quality, in super quick time at a busy time of year

My immersion tank failed and leaked through the ceiling, our old Potterton boiler was also on its last legs so I called Neil at NJS on a Friday to repair and replace large parts of my original system. He appeared on Monday and had sent his quote by the Wednesday. After several questions, additions and changes on my part I agreed to go with Neil. He replaced my vented system with a new boiler, immersion tank, cold water tank, 3 new radiators, 18 new thermostatic valves and a long run of new 22mm gas pipe (my original was 15mm) and all associated piping, new valves, filters etc. Neil and I spoke on Sunday 1st December and I said I ideally wanted the system complete by Christmas but I thought this was a big ask so asked Neil if he could get me hot water by Christmas and complete the install early in the new year (whilst also avoiding the weekend of my wife’s birthday!!). Neil said he was sure he could do that and could start on Thursday 5th December. He arrived with 3 of his team (Martin, Scott and Andy, Justin the electrician also appeared) and they cracked on. The whole system was installed, commissioned and fully operational by 10th December!! I was absolutely delighted and it has been working a treat ever since. Neil and the team were very professional, nice guys to work with, excellent work standards and very communicative. I cannot rate Neil and the team any more highly and would definitely recommend them. I will certainly use them again for future works. Thanks guys.

Central Heating Service - Highly Recommended

Our central heating was not performing well. Neil turned up on time for both the quote visit and the visit to carry out the work and was pleasant to have around. The work required him to do a power flush, replace the pump and then rebalance the system. This took him most of the day and he worked meticulously to solve issues that arose during the work. At the end of the work the heating was working effectively and we had a lovely warm house again. He arranged the work to cause minimum inconvenience.

I had a new boiler fitted and I couldn’t be happier. Neil visited the property and explained all aspects of the work required, he provided the quote promptly and carried out the work at the agreed date with no delays. Nothing was too much trouble, he also helped with a couple of other areas connected with the job which were not included in the original quote. Overall, NJS were professional, reliable and did a superb job, thank you.

Neil and Scott arrived promptly and had four new radiators beautifully fitted and working in a matter of hours with the minimum of disruption despite having to move furniture and relocate some plumbing. I highly recommend them for their professionalism and tidiness! The house is so much warmer. Amazing job at a good price.

Neil as always was very responsive and worked with the builder to understand the requirements to be able to provide a quote. All the work was completed in the time frame, to a high standard and to the agreed budget. They also were very tidy and cleaned up after themselves.

Ceiling damage, leak identification and repair

Neil and his team found the root cause of a leak, causing marking on the kitchen ceiling. The job was comprehensive in terms of trying to identify the leak and the repair work excellent, as I cannot tell where the leak was. He and his team are trustworthy, experienced and, if ever needed, I will use them again with no hesitation.

I have used Neil prior to moving to my current "doer up" house, so he was the first tradesman I called when we moved in. Work included two new bathrooms with showers, new boiler with a gas diversion and installation of new radiators. The quality of the work was first class and Neil and his team offered good advice as we uncovered unforeseen issues. I would not hesitate to recommend NJS for heating and plumbing works.

I can't recommend Neil and his team enough. I have had new boiler and 2 bathroom refits over the last year. Neil gave us a quotation to start the work and kept within our budget. Neil and his team turned up everyday as agreed and kept to our tight schedule, to get work completed on all 3 jobs. His workmanship is outstanding and he has been so helpful giving us ideas for the bathrooms as well. His communication has been great and has kept us informed at all times on what he was doing and when he was carrying it out. He even gave us a aftercare call to make sure we were happy with everything, even asking on the day of completion. I can fully recommend Neil and his team, and now would not use any other company to carry out any of the services that Neil can do.

I had Neil and his team install a new boiler and bathrooms following a large extension. Any issues which came up during the installation were dealt with by the team and they kept me informed of options and their recommendations, including potential layout ideas for bathrooms. Everything was always tidy and they couldnt do anymore to help during this time. Neil has also called back to ensure that things are working as expected and has always been able to answer any queries both practically and over the phone I had about the new heating/underfloor system and boiler. I would have no hesitation in recommending their services. Great work all round.
