Honest, trustworthy and sorted the issue quickly
I had an issue with my pump and hot water. They sorted the issue quickly and efficiently. I also really appreciated not being ripped off because I’m a single woman who has no idea about this kind of thing - various other companies have definitely tried to fleece me, and I really appreciate that this operates with honesty and integrity. I’d recommend them to anyone.

Trustworthy and the best
Terry is truly professional, extremely knowledgeable, a masterful engineer and a thorough gentleman. He installed a new boiler in my house in Tooting Bec, and he was a pleasure to host and have about. His knowledge about boilers is top class, and I trust him 100%. Would highly recommend him - he gets 5 stars. If anyone is looking to repair or replace their boiler, Terry is your guy.

New heating system from an excellent craftsman
We are based in Carshalton and got Terry to install a new Viessmann Vitodens 200-W boiler, Joule Cyclone high-gain hot water cylinder, and water softener. The boiler was repositioned and the old layout was redesigned so the system is now a lot simpler and neater with unnecessary pumps and pipework removed. The new system looks fantastic. Terry is a true craftsman with extensive experience and expertise as an engineer and an obvious passion for the field. He took the time to understand the existing system and our requirements before designing a system that works for us and more importantly the house. Efficiency is key for us and the new system has been designed to operate at a lower temperature, helping the boiler run more efficiently. Even though it is summer at the moment we are currently using a third to quarter of gas for hot water compared to the previous system. It will be interesting to measure the improvement when the heating is used going into winter. It's been a pleasure to have Terry around as he is very friendly and easy to talk to. The work has been very neat and organised with excellent workmanship. Terry has also been keen to ensure we are happy with the work and that we understand the new system and its technical characteristics. The overall focus has been on getting the job right and correct and as a result we have a huge amount of trust in Terry and what has been done. We highly recommend Terry and will definitely get him back for any future projects.

Great job and took the time it needed
We are based in Tooting and Terry came to our rescue with a new boiler after our old one failed. A full power flush and some very clean and tidy work later and we are back up and running. Helpful advice on running it efficiently too. A real expert and patient too dealing with a full house of kids. Many thanks Terry.

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.

The job always comes first
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.

A great job well executed
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.

Painstaking, and thoroughly professional
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.

Boiler replacement
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.

Boiler Installation
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

No quote to date
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.

Very helpful, well prepared and quick
When I first contacted Terry he was apologetic that he couldn’t come for a week but suggested another larger company who, unfortunately, had an even longer queue. When I went back to Terry he asked for photos of the problem (leaking flow rate valve for under floor heating system) which meant when he came he had the correct part to replace the leaking flow valve. As a result, when he came it was sorted out very quickly. There was also another fault on the boiler which stopped a final test of the system but Terry had a look at the boiler to see if it was a simple fault to fix which unfortunately it wasn’t and so had to wait for a technician to come under my service contract, but Terry left instructions on checking the valve was working properly. Overall Terry was very knowledgeable and very helpful and I shall be looking to using Terry for all my central heating service and maintenance in future, particularly as he readily deals with under floor heating unlike most service plans.

Very professional and polite service and excellent communication from the time the appointment was booked to the actual servicing of our boiler. As first time buyers, there were a few things we didn’t realise had to be checked - Terry took the time to explain everything to us, as well us explain any work needed. I would have no hesitation in recommending Lambert Plumbing & Heating - we will be using the service again.

He takes an obvious pride in his work. He is courteous, with great attentions to details and good at explaining the nature of the problem and what would be required to resolve it. I will be very glad to have him to carry out any further work in the future. I would highly recommend him without reservation.

Expert professional
I have used Lambert Plumbing and Trading to install a Viessmann boiler 3/4 years ago. They came very highly recommended. They talked through my needs and requirements and installed a boiler with beautiful pipe work! They returned to service it last year and today came to fix a malfunction. Great communication, product knowledge and a genuine love for engineering and heating systems. I am out of town, they had to travel and stayed tirelessly to fix the problem. I am so happy to have a warm house and hot water again. Thank you for your care and expert service.

Terry Lambert
Terry Lambert, Plumbing and Heating Engineer is the most trustworthy, kind and diligent heating expert. Most gas engineers I had called out in the past said that the boiler was unfit for use and the 8 metre flue run an impossible job. Terry came round and went through all the options. He also fitted in the work between other jobs at the weekend. Now I have hot water and radiators that work. Terry Lambert is kind, quiet, hard working and the most dedicated workman I have come across. Book him and you will not regret it.

Tricky job done at short notice
My mother's old boiler finally packed up - she had no heating and no hot water. I found Lambert Plumbing and Heating through Trusted Traders. Despite the busy time of year, Terry gave up his weekend to do a major installation at short notice and dealt capably with numerous challenges. (The old boiler was situated in a hugely inconvenient location, near the centre of a small block of flats with an 8m run to the outside wall and no flue inspection hatches). She now has a lovely new Worcester Bosch compact combination boiler installed in a different location. I'm very pleased with the service he provided and will not hesitate to recommend Terry to my friends and colleagues. Terry, thank you for looking after my mum so well.
