These people were superb

From an initial enquiry to a then urgent 'I need you to fit a new boiler in the week before Christmas' the service was excellent.
Andy talked me through all the options and managed to get a date within 2 days.
The fitter was excellent, he put in a very long day to get the job done, was helpful and reassuring through the process and also fitted a new light where the boiler was located as the old one smashed in taking the old boiler out.
Having to urgently get heating and hot water, I can not recommend Lewken enough for making the process so easy - at a very competitive price.

The work was carried out to a high standard.
He cleaned up and removed all the waste.
Before leaving he made sure the new boiler was working correctly and had no leaks.
No question was left unanswered, making sure I fully understood how it all worked.
100% satisfied.

Poor after installation support

I found this company does a very hard sale, but post installation customer support is non existent. I had a new boiler installed last year which had issues after a few months, I had to get another company to come and sort it out. I was stuck with no hot water or heating, and between this company and the warranty disagreeing on whose responsibility it was.

Lewken did a great job replacing my boiler.

Lewken replaced the aged central heating combi boiler in my house. From start to finish it was a pleasure. They visited to assess my installation, ensure that it was up to standard and generate a fixed price quote on the spot that satisfied my needs.
After agreeing the details and date the technician arrived and completed the works cleanly, quickly and effectively.
It was a pleasure doing business with them.

Fast response and very professional service. They called me back straight away once I got in touch and came to assess the same afternoon and arranged for a new boiler to be installed as soon as possible. Great prices as well and friendly team. They also managed to fix several tricky issues that came with the installation. Would highly recommend!

Great Installer

Great guy that came to install. Very professional. He did a first class job. Very clean pipework and he replaced some of the old dodgy plastic piping with new brass. Even left us some spare descaler. Boiler is top notch. Lewkens just loses a point from me as the boiler wasn’t delivered on time and we had the water off for quite a while.

Jamie and Andy have provided 5 star service. They were not the cheapest quote, but I knew I had made the right choice for the boiler replacement company and also the right boiler.
Mason carried out the work in a very professional manner. The finished job very neat with the new boiler and the changes necessary in the airing cupboard. Mason explained the operation of the new boiler very easily and I would therefore always strongly recommend Lewken Plumbing and Heating to anyone interested.

Our tired and sad boiler was over 12 years…

Our previous boiler was over 12 years old and was starting to become troublesome. My wife and I felt that it would probably be false economy to have it serviced, repaired and the system flushed out etc. We made enquiries online to get some idea of the likely cost and were pleased that Lewken Plumbing and Heating who are based less than 20 miles away responded very quickly. We had phone calls and confirmation that their representative Jamie would visit us yesterday to assess our requirements and explain what packages he recommended.
He took time to explain the company's offers and happily answered any questions that we raised.
A very easy, not pushy, professional, knowledgeable and confident presentation.
We agreed to go ahead, paid the deposit and the cheerful 2 fitters arrived this morning to take out the old boiler, carry out all the scheduled work and fit the new boiler. Once it was fitted and tested, the mess and scrap cleared away they explained the key points to me. The installation was very neat and tidy and completed comfortably within 1 day.
Based on the service received from their office, representative, the fitters, speed of installation and the all in very competitive price, I would not hesitate to recommend Lewken Plumbing and Heating to anyone requiring a new boiler.

Great after sales service too

In addition to the quality and value of the initial work, they have also provided great service afterwards, and were very happy to be contacted over the weekend and gave advice.

Great Work and Very Experienced

We just had a new Combi boiler installed by the team at Lewken, moving from a bedroom to a bathroom and they were great. Very professional, fast and experienced. Coming up with solutions on the fly to make a 30 year old system work even better. My thanks to the team, Gary and Tyler.

Had a new boiler fitted recently as mine was old and out dated. Jamie was absolutely perfect in every aspect of this job from the start quote to the finished product. Really fair prices and efficient work. Outstanding work provided by the Lewken team. Highly recommend
