I used this company to supply and install a heat pump, and subsequently service it. They were very straightforward to deal with, gave good practical advice and did the work on time and to budget. There was one minor issue discovered subsequently, but they attended to this promptly with no charge made. The staff are very pleasant to have around our house - a very pleased customer.

Air source heat pump installation

NCS installed a Grant air source heat pump into our property, from the first contact with NCS to the completion of the installation I cannot fault this company. They put me at ease right from the start from the first enquirer call. Totally flexible regarding the customers’ requirements, many other companies I obtained quotation from would not offer a system to suit our requirements, not NCS they are fully customer focused. The installation was seamless. Special thanks to Dawn and Stuart. I would have no hesitation in recommending NCS.

Radiator change and boiler service
Customer Service
Quality
Value
The company were excellent at stepping in when another plumber let us down. We can't fault the work or professionalism of the engineer. We were however shocked by the final bill - well in excess of the quotes of other plumbers. We have a large house, but a boiler service, gas safety certificate and single radiator change resulted in seven hours labour charged at £80. We've had a number of rad changes before which didn't take so long and were charged with a set price well below our final bill of £560 plus VAT. So, a great firm,but watch out for the hourly charge - we were expecting a half day's worth of work only.

The trader replied (on 14/03/2025)
Thank you for your feedback. We take on board your comments and perhaps we should have been clearer on the anticipated timing of these things but unfortunately, when you have never attended a property before, it is difficult to give any estimations. We fully drained down an entire system with 14 radiators, refilled the system and bled the radiators, alongside a boiler service and Gas Safety Inspection. When the engineer drained down the system, it did take longer than he anticipated (as did refilling it) and unfortunately this took up a bulk of his time. The new radiator that you provided was not a like for like replacement and pipework had to be altered to accommodate installing the new radiator. He also noted that he struggled to bleed the radiator at the top of the stairs due to the units in the way. Upon investigation he found that the bleed valve was very rusted and there were signs on the floor that it had leaked previously. Unfortunately, all of these factors contributed to the job taking longer than we would have liked. Please rest assured that our engineer is incredibly experienced and it was not a lack of experience which led to the additional time taken. We too were only expecting half a day’s worth of work and had other jobs booked in which we had to cancel so it was not in our best interest for this particular job to overrun. We are glad that you are happy with the rest of the works and we hope to work with you again in the future :)
Emergency mains water leak
Monday morning big puddle in the front lawn around the area of the water meter. The water board suggested contractors assess the situation. I phoned NCS Property Maintenance who came out promptly the next morning. Their assessor Tony calmly looked at the problem and emptied the area of water after turning off the nearest stopcock. He had a good look around and took a video on his phone of the leak which was clearly on the side entering the water meter. He informed me that was a water board problem and I needed to get back to them. For me, this was a complete emergency but Tony dealt with it all in a very calm professional way.

Excellent advice and skilled installation of an Air Source Heat Pump
Customer Service
Quality
Value
We are new to ASHP's though very familiar with the nature of the building and services industries, but quickly realised that NCS really knew what they were doing and were giving us sound advice. Essentially we've taken their advice on all the components of the system, but have taken the major decisions on its layout based on their more general advice. Their staff are skilled, experienced and effective. We've had a couple of hiccups along the way, and each time they're been swift to sort things out effectively. You might find someone to put in a cheaper bid for an ASHP installation, but we doubt they would achieve the quality of advice, workmanship and customer service we've received. We did need to instruct some changes to their work, and these have been carried out at quite reasonable cost.

The job entailed replacing an old boiler first installed 2003 in a cupboard in our kitchen. It was important, although not essential that the new boiler should fit inside the same cupboard. The two men that carried out this work ensured this the boiler fitted inside the cupboard and carried out all the work efficiently. The surveyor was insistent that the new boiler should be as efficient as necessary and discussions with him were satisfactory. An existing fault in one of the valves was located and a new valve fitted again efficiently.

We asked NCS to replace our old oil boiler with a new electric heat pump. We live overseas so needed a company who would take a lead and coordinate the whole process. NCS were excellent throughout the entire process. From initial advice on our eligibility to obtain the Government funding, to site visit, scoping, and installation, everything went 100% smoothly and we had a very limited level of involvement. They were able to work to our tight timescales to start and complete construction and all communications were timely and clear. I wouldn't hesitate to use NCS in the future.

We had nine solar panels installed to three faces of our roof by NCS Property Maintenance in August 2022. We chose them because they had very successfully installed an air source pump, water tank/immersion heater, radiators etc in our house a couple of months before. The scaffolding was erected without any problems and the installers carried out the work quickly and efficiently. We were very pleased with the whole process. NCS Property Maintenance are also very responsive and have visited us a few times to help me get the best from our system. I highly recommend them.

An amazing and prompt job from start to finish. From placing the order on line with Worcester, through to dealings with the company selected to install the boiler and then the installation, everything was spot on, even in extreme temperatures, the boiler was fitted in the fully insulated loft.
