Outstanding workmanship.
Customer Service
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.

Great job, helpful and tidy.
Customer Service
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.

Extremely reliable & hardworking
Customer Service
We have used NJS Plumbing over years to service our boiler and repair when necessary. Neil has always gone above and beyond to get any repairs done and has been completely reliable. Recently we had a leak in our en suite shower and so had to replace the shower and repair extensive damage to the ceiling below in our sitting room. Neil managed this work for us; organising the tilers, plasterer and painter. He was very helpful and patient with us while we decided the best course of action and the work was completed to an extremely high standard. We would highly recommend NJS.

Always reliable and problem always resolved.
Customer Service
We have used NJS for the last 16 years for any plumbing and heating issues in any house we’ve lived in. They are easy to contact, reliable and the issue, however complicated, is always resolved. Most recently we had a problem with our boiler intermittently switching itself off and typically when Neil from NJS arrived, it was working fine. However, Neil soon found the problem and the boiler is now working perfectly again. We trust NJS implicitly and just wouldn’t go anywhere else. We really can’t recommend them highly enough.

Consistent excellence
Customer Service
Neil has been our go-to man for plumbing since we moved to the area. He is unfailingly committed, diligent and reliable for jobs large and small. He recently completed a complete strip-out and refit of our shower room. From the outset, Neil showed his expertise - spotting things about the room that no-one else had. When we encountered the usual hiccups along the way (every job has them), Neil just dealt with them and put things right. We now have a new shower room completed to a high standard of workmanship. We wouldn't go anywhere else.

Excellent work
Customer Service
Although clearly busy Neil found time to schedule our urgent work which he did well at a fair price. Even though he was supplied with an inaccurate wiring diagram and I offered to pay more (as it took longer and wasn't his fault) he stuck to the quotation. Most important he quickly understood our quite complicated heating system and addressed the problem.

Great quality work
Customer Service
NJS fitted 5 new towel radiators for me. They provided a reasonable quote and lead time, arrived on the day specified and completed the work to a high standard on time and on budget. I wouldn’t hesitate to use NJS again.
