Boiler installation
We would recommend using jamie and his team after the work they did fitting our new boiler we found them to be extremely efficient and professional.
I’m very satisfied with LEWKEN
The representative for LEWKEN explained exactly what the engineer would do when installing the boiler.
This was completed efficiently and quickly in a professional manner.
The cost was very competitive and I have been happy with the results.

How I chose LEWKEN
Having looked at the Governments generous grants for Heat Pump systems and been approved for the money,
I decided it was not the right thing for me and cancelled.
Whilst thinking about changing my very old and reliable Potterton boiler I decided to check out what would be the best modern and economical boiler on the market.
I went on a comparison online site and was given 4 plumbing companies to try.
I contacted Lewken and spoke to the owner Jamie about my requirements and reason for renewing a boiler that was still working well after possibly 40 years.
Everything does have a life but I wanted something that would be efficient and last.
He recommended Vaillant as being in his experience a really good boiler and asked if he could send his own surveyor Ivan to inspect the property and get a quote arranged for me.
Ivan arrived at the appointed time and did a thorough check and advised that the new Vaillant Eco Tec Plus would be the suitable for my house as it had a Stainless Steel Heat Exchanger which is needed for a house with Water Softener. This was the expertise I wanted to hear.
I placed an order with Jamie and told him he could choose any suitable time to do the installation whilst the weather was fine and boiler not in use.
I was given a date for the closest engineer to do the installation and it was Dan who turned up on time and carried out a very professional job without any interference to the running of the house.
The system was hot flushed and a particle filter fitted in line. The system was run up to temperature and all radiators checked.
I would have no hesitation in recommending Lewken for your new boiler without fear they would overcharge.
Well done the Lewken team and I wish you much success.
Exceptional Service and High-Quality Installation – Highly Recommend!
I recently engaged Lewken to install a new combi boiler and radiator system in my home, and I couldn't be more pleased with the service. The installation was completed to a high standard.
It's refreshing to find tradespeople who respect your time and are as communicative as Jamie. He clearly prioritizes meeting his clients' needs, tailoring his services to ensure complete satisfaction.
Ivan also offered me valuable advice for my installation. He took the time to explain different options, helping me choose the best system for my needs and budget.
I was particularly impressed that they let me choose my own radiators, giving me the flexibility to select the style and design that suited my home, while ensuring everything worked perfectly with the new boiler.
In terms of pricing, they offered a competitive rate that was transparent with no hidden costs.
Overall, I highly recommend Jamie and Ben for any plumbing work. I’ll definitely be using their services again in the future.
Friendly and professional
James and his son were very friendly and professional. Changed my cracked cold water tank, were prompt, efficient and I would recommend

Exemplary work and great company.
From start to finish LEWKEN were prompt, efficient and easy to deal with in regard to installing a full central heating system. Their work throughout was exemplary, Tyler and Alex were on hand to answer questions, instruct on their plans and carry them out with the utmost professionalism. A real pleasure, thanks for your great work.

Boiler Upgrade.
We've just upgraded from an extremely old cast iron boiler in our kitchen to a new combi boiler upstairs in our airing cupboard, which took two days.
This meant changing the gas pipe size and rerouting it, getting rid of the tank in the loft and the hot water cylinder.
I was secretly dreading the upheaval but need not of worried. We made the right choice. Professional, polite, respectful of property. A job well done and always ready to answer my questions. Thank you.
New Combi boiler install.
Ivan who came to do the survey, very thorough and very friendly no heavy pressure tactics. Ben who came to install the new combi and remove the old boiler was very professional, superb job explained everything that was happening. Lyndsey who organised the install was friendly and kept me informed. Overall I couldn’t be happier with the new boiler and would have no hesitation in recommending Lewken. Great job guys.
