Highlights

"Terry did a boiler and heating installation for me about ten years ago. That was a great job but since then he’s become very technically aware and is at the forefront of the industry. If there’s a tricky job or something where perhaps other advice doesn’t seem right, I’ll always do my best to get Terry to do the job."

"Terry recommended a replacement during a recent annual service for my old combi boiler, which was identified to have been leaking through the heat exchanger. He didn't charge for the annual service and suggested a like-for-like replacement rather than upselling and provided a quote for pretty promptly and was patient in explaining different options for accessories. He was punctual on the day and clearly explained the steps he was going to take. As he was mixing pointing for the external wall he was even kind enough to fix the pointing above my bedroom window. After the installation I found an issue with the filling loop repressuring the boiler excessively. It was unconnected to the installation but Terry followed up on the phone and came out in person to check the issue for me in any case. I am pleased with his dedication to a providing a quality service. Would recommend him if you're after a knowledgeable and reliable tradesman."

"I have being using Terry for over 5 years to regularly service and repair my boiler. Initially, when I moved into my flat I went through a lot of different engineers, who either continually misdiagnosed or kept trying to get more money out of me, that is until I found Terry. He has been able to diagnose and repair my boiler when others have failed. He also charges a much more reasonable price to do so. Recently the boiler (this is an old boiler) has been playing up. So I contacted Terry to come take a look. He talked me through the issue and explained that the work would cost about half what a new boiler would set me back, but as the boiler was getting on and said he could not guarantee that something else would not go wrong. He explained that the new boiler would come with a guarantee. Terry kept in contact with me that day, discussed my options, requirements and various pricing and gave me a quote that afternoon, having had my parents boiler replaced last year, I can say it was very fair. Due to where the old boiler was seated I want the new one is a slightly different location, which involved moving a cupboard. Terry arranged for the cupboard to be taken down and put back up in the new position and because he had taken the time to identify what I wanted, this was all covered by the original quote, no additional/hidden charges. I will continue to use Terry and am happy to recommend him."

Terry completed a checkup on my boiler and kept me fully informed on progress throughout. I was very pleased to get a full update on the status with clear understanding and informative advice on ongoing care and maintenance. Terry is a complete professional and I would definitely recommend his expertise to contacts and friends.

Terry was recommended by someone we knew. When our Worcester boiler was not keeping pressure and the radiators were all checked and ok for air, I didn’t know what was wrong, my usual plumber had turned off his phone. I contacted Terry and he was really approachable and helpful when I called and gave me pricing without even asking and said to text him with my details. After doing so he contacted me a few days later to arrange a date and came to do the boiler service. This was much needed, the unit was stripped and the leak found and part replaced, he showed me what he was doing and obviously is passionate about his work. The boiler was serviced and re pressurised and now works perfectly. He was very tidy and enjoyed having a chat as well. Would use his services again in an instant. Thanks so much- and I appreciate you also tightening my leaking outside tap- that was a great help so I can water the garden.

i have had my boiler installed 10 years ago by Terry .It has been a difficult job with changing all the pipes from one side of the flat to the other and several other obstacles which made other teams to reject the job as too complicated. Terry not only didn't fear to take the job but he had finished it in 2 days . He is very knowledgeable, efficient, focused, and he works very tidy. I was so pleased with the way he works that i have never used anybody else to to look after my boiler since. He is very prompt with emergency situations and sometimes even gave me guidance over the phone for minor problems which he didn't need to attend. Highly recommended.

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.

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.

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 promptly attended my request within an hour as soon as I mentioned my boiler leakage. I am very satisfied with the work he carried out and his professional services. 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.

I had not used Terry previously but when my heating failed a call to him resulted in some immediate advice for a temporary solution and a date for the work to be undertaken. The work was completed quickly and the charges more than reasonable. Would use these company again without hesitation.

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.

Our first time using Terry, but he will be our go-to from now on. He was polite, efficient, and took the time to explain our problem, what he would do to fix it, and why. Very happy.

We have used this company for a number of years now to perform our heating and plumbing needs. Terry arrived recently to do our annual boiler service, and as usual he showed what a true professional he is, he always explains things with recommendations going forward, he is a very friendly and courteous gentleman and it is a pleasure to have him working in our property. This company is highly recommended!

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.

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.

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

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.
