Central Heating Install and Service

Terry revamped and installed a completely new central heating system at my 4 bedroom house in Purley. He designed, project managed, and installed a new heat pump, wet central heating system, including underfloor heating and radiators. Terry did an absolutely brilliant job across the 2 month project. His communication was great and he was very considerate of the fact that we were still living in the house at the time of the works. It’s been a full year since the install and the system is operating very well. The house is warm and the hot water hot! Terry also came round recently to do the annual service on the heat pump so that we’re ready for the coming winter. I really couldn’t recommend Terry more highly - he’s brilliant.

I was introduced to Terry via HeatGeek for an ASHP install. It quickly became apparent, Terry was very knowledgeable. The heat loss survey and initial consultation took the best part of a morning compared to just over an hour from a national company. His attention to detail gave me lots of assurance, especially as I had micro bore pipework, which adds some complexity to the calculations. From the outset, he was clear, the 'quality of the job always came first'. When it came to the install, there were a number of upgrades he insisted on, which he explained, avoids foreseeable problems later on (for example a large upgraded valve to improve flow that has an integrated magnetic filter, in addition to the recommended magnetic filter) and all have proven their worth. I also insisted on some upgrades over and above what was required for the system to work (I swapped all the radiators in the house so they would match, instead of the 6 which were recommended). Through out, he was always on time, neat, tidy, a true professional, whose wealth of knowledge and expertise shone through and as a result, I could not be happier and the system works a treat. I would happily recommend Terry to you.

Thanks so much for the thoughtful review—it means a lot. It was a pleasure revisiting the heat pump system and making sure everything’s still running smoothly a year on. I always aim to build setups that last, and it’s great to hear the performance and comfort are holding strong. Your feedback on the consultation and upgrades is especially appreciated. Every home is different, and I believe in taking the time to get things right—from diagnostics to final handover. Glad the magnetic filter and tweaks made a difference. I’m always here if you need support down the line. Thanks again for the recommendation and for trusting me with your home’s heating. Lambert Heating & Renewables | Built on trust, not pressure

We engaged Terry to replace our 35 year old boiler with a new combi boiler. After surveying the existing system he made recommendations as to how he would install a boiler in way that would minimise stress on our old radiator circuit and lower the risk of problems developing. This set him apart from other companies that quoted for a standard installation. His quotation was competitive and reasonable considering what was involved. The work involved disconnecting and removing the cold water tank and hot water cylinder, pressure flushing the radiator system and fitting new thermostatic valves, and installing the new boiler with the necessary adjustments of the plumbing. He worked quickly and efficiently, clearly knowing exactly what he was doing and making a very neat job of all the new pipework. He took the trouble to explain everything he was doing and why. Friendly and unassuming, he was a pleasure to have pulling your house apart.

Terry responded quickly when I called for assistance with a leak on the Megaflow pipe work. He ordered the part and arrived the next day to fix it, working in tight conditions without complaint. I really appreciate the quick turnaround and will definitely call Terry again if needed.

Terry recently did a very complicated installation of new boiler and hot tank for us. It was done to budget, and is simply immaculate: he sets himself highest standards of workmanship and only allows shortcuts if they make for a better installation. The work overran a bit but Terry stuck by his estimate, so no extra charges. The quality of the installation is absolutely superb: you could exhibit Terry’s pipework in Tate Modern. He arrived every day when he said he was going to, and was careful to explain what he was doing as the process unfolded. You might find cheaper out there, but you won’t find better.

We have a boiler in a flat we lease British gas had left inoperable. As the boiler was getting on we decided to replace. Terry did this for us economically and managed to schedule and complete the job 48 hours after his first visit. We were really impressed by his helpful attitude, speed of completion, communication, professionalism and price. We will be terminating our British Gas Contract and using Terry from now on, despite living away form London. Highly recommended.

Overall a satisfactory outcome because: When he arrived, on time. He showed great knowledge of our problem and was able to solve the problem, but suggested a new boiler be installed. We discussed it and decided to go with his suggestion. He ordered a new boiler and installed it after delivery. He worked slowly and carefully, when the work. was finished he explained the boiler instructions and details of the guarantee. He tidied up after completing the work and ensured the boiler was working correctly. He was smartly dressed, answered all the questions we asked and was polite throughout. He has contacted us twice to check all is performing well

Contacted Terry on 29 August. He arranged to survey a Vaillant Boiler and Megaflo installation which needed to be relocated 4 m away. Terry attended my property on 9 September. Terry said he didn’t like working on Megaflo’s and suggested a different manufacturer for the 2019 cylinder which has been hardly used. I refused. Chased Terry for the promised quote on 5 October, giving him the opportunity to say he was not interested in the work. He said he would look into it. No response since. Sharing this review to balance the glowing recommendations. Just as potential customers can be time wasters, tradesmen can definitely be just as discourteous.

Hi Thank you for taking the time to leave feedback. Our customers opinion matters to us. Your feedback is not factually correct and I feel it right to respond, although we have not conducted business and merely had an informal chat. We do fit and work on Megaflo cylinders, the issue you had was that your boiler, cylinder had been badly installed and needed relocating to a new position due to the boiler flue length and angle of the flue installation not complying with regulations, along with various other regulation issues. The new proposed location did not have the required height to meet servicing clearances, as discussed an option of a smaller cylinder would solve this problem or a combination boiler as you had suggested which would have removed the cylinder As you have said you refused to take my advice and we do not carry out work that is not to standards. I do feel for you in that you have had very poor workmanship by others, failed building control inspections and had to pay for work to be carried out twice. I wish you well and hope your works are resolved.
