Fast problem solving in new flat
Customer Service
We’d just moved in to our new property and discovered no running water even with all isolators open. Neil quickly identified a broken isolator and had it fixed the next day even though it required a non-standard part. He kept us updated and explained the issue so we could understand it, and parts and labour costs were very reasonable given the short notice. Great for peace of mind when we had so many other things going on!

Neil put in our underfloor heating and air source heat pump. We are self builders, he was very patient waiting for us to get to the correct stage for him. He offered advice along the way. Would recommend Neil to anyone. Our build is toasty!!

Great company
Customer Service
Neil and his team installed our Grant heat pump and hot water cylinder. We're very happy with the advice received, the communication and installation process, as well as the system itself.

Great response
Neil fitted our replacement gas boiler in January 2022. He serviced it January 2023 and we are very happy with the service he provided. In May this year, we were away on holiday when my son (home alone) rang to say there was no hot water. At 9.30pm I texted Neil to see when he might be available for advice or if necessary to visit as we were not due back for several days. He interrupted his evening to respond and after asking a few questions, explained that the error code showed an external interruption in the gas supply, had caused the boiler to shut down. With his help, I was able to talk my son through the process of relighting the boiler and normal service was resumed. We can not thank him enough for his kindness and our holiday was saved.

Excellent solar thermal repair and new boiler installation
Customer Service
I would be happy to recommend NCC Southeast Ltd to anyone needing plumbing, boiler installation or solar thermal repairs. They were knowledgeable, courteous, and good value for money.

New Boiler
Customer Service
Neil installed a boiler for me 15 years ago and has serviced it regularly. It came to the end of its life last week. So Neil replaced it with a new gas boiler. We talked about other greener options but my house just wasn't suitable for an air pump without a lot of disruption. We booked a day that suited me and the work was done quickly and cleanly and at the price quoted. I'm really pleased with the new boiler and will continue to get Neil to service this one.

Damaged floor, didn't follow manufacturers instructions, won't help us fix the issues
Customer Service
NCC installed underfloor heating across 3 levels at our house beneath engineered flooring alongside a heat pump. It turns out they used a product designed for tiling, rather than wooden flooring, and did not follow the manufacturer's instructions (which say that self-levelling compound or screed must be added if used below wooden flooring). This means that beneath the floors (which require even heat) there are hot pipes at 50C separated by cool insulation. Their manufacturer says it's essential to install thermometers beneath the floor to avoid damage to the flooring - this was not done. Their manufacturer says that concentrated pipes should be avoided or insulated to avoid overheating of the floor. In some sections 7 pipes have been laid together where the pre-cut grooves in the boards normally support 3. In those areas the floor is being heated to 30.5C way above the safe limit of 27C, which the majority of the rest of the floor is at 21C. So both damaging the floor and failing to heat the rooms. Two months have passed since we complained, NCC came out once and all they did was cause the floors to overheat more. They didn't fix the flow meters as we had asked. During installation Neil's constant refrain was "I've run my business from home for 33 years, no-one has ever knocked on my door". Yet at the first sign of problems, he's gone.

The trader replied (on 18/02/2023)
Please be factual; we are the 2nd company you have had a protracted engagement with for underfloor heating (UFH). We installed UFH across 4, not 3, levels on various floor finishes, tiling, wooden and solid screed. January 2023, a site visit with the UFH manufacturer, who conducted a full inspection, confirmed the correct installation and the product used IS suitable for ALL floor finishes. Our response remains the same to your subsequent complaint letter, 21/01/2023. Our quote states the UFH products' including cement boards. Installation of your flooring used the wrong method, a floating floor with an air gap, not the flooring manufacturer's recommendation. We agree with you, a self-levelling compound or screed should be used for flooring installation. Dennebos also states the UFH must have been operable at normal capacity for at least 10 days or 14 days at 2/3 of its capacity. Yet, your flooring was laid before the UFH system was brought up to temperature, tested and floor probes fitted. The flooring manufacturer advises that suitable thermal barriers are needed for floor fitting in concentrated pipe areas. We also rectified the UFH pipes that someone cut through while new fitting new stairs. We have NOT gone, responding to your >100 emails, WhatsApp, phone calls, reviews and complaints, & now GDPR Subject Access Request. Neither the UFH manufacturer nor we are at fault; with the correct flooring installation, you will benefit from an efficient heating system.
Going above and beyond
Customer Service
After a series of issues with our solar and underfloor heating, it was such a relief when a neighbour recommended Neil. He sorted out both the original problem and the problems created by other people trying to fix it. Since then, he has also fitted a new boiler and upgraded my shower. It makes such a difference to find someone who knows exactly what they are doing and whose advice I trust completely. He goes above and beyond, finding time to do any necessary adjustments, even when very busy. I am particularly grateful for the time I was home unwell recently, with sub zero temperatures outside, and the heating playing up. Neil fixed it straight away and hurried on to other jobs before I had time to thank him properly. So thank you Neil!

Superb service
Customer Service
When our boiler broke down, I contacted Neil and he came that evening on his way home after work to fix the problem. Incredibly polite and professional, he diagnosed the problem really quickly, had a spare motor in his van and had fixed the system within an hour. I was so impressed with Neil and would recommend him to anyone.
