Plumbox are the best
Our CO2 detector went of a number of times during the night so of course we were worried. I called Plumbox in the morning and the gas engineer arrived before lunch. They check everything including the boiler and took readings which didn't show anything so they checked the detector and found that it had expired.
Thank you Plumbox Team for you speed and efficiency!

We wanted our en-suite bathroom reworked, and Plumbox were recommended by a friend. From the very outset they made sensible advice on how we might best achieve what we wanted in the most economical way, helping us with the design, and putting us in touch with the supplier. The job was started on the agreed date. They were very tidy and cleaned up every evening. They said the job would take a week, but took 8 days. The delay was waiting for a final part to arrive. We had a few teething problems (not their fault) but they returned promptly and solved the problem. The contract price was below what we expected, and the job was brilliantly executed on time. Would recommend without hesitation or reservation

We have been really pleased with the work carried out by Plumbox. We would especially like to commend Adam who re-fitted our en-suite. He was very polite and considerate. Adam also took pride in his work and attention to detail. The only criticism we have is the communication with Michael and the Plumbox General Office. They were very aware that this was not always as good as it should be but despite this I have no hesitation in recommending Plumbox. I would also recommend Adam as a person who could be depended to complete the work to a high standard. I am happy to give Plumbox 5 stars for Adam's hard work.

Great company .
Communication was excellent and engineer punctual and knowledgeable.
When I had a problem with the settings on my underfloor heating I was given a very prompt call back and the advice I needed which avoided me having to pay for a call out .

As with any work requests I always research 3 or so reputable traders. On calling Plumbox I spoke with Ciaran. Ciaran was friendly, professional and informative. I decided to go with Plumbox in the end. The friendly reception drew me to Plumbox. The plumber was on time, quick to carry out the annual boiler service. I would recommend Plumbox and would also use them again.

Plumbox have just installed a new boiler for us and carried out a complete refurbishment of our cloakroom - new fittings, floor and wall tiles. They made everything as easy as possible for us, and all the work was completed to a very high standard. The two plumbers, Adam and Kai, were extremely reliable, respectful and friendly.

Plumbox did a great job at resolving my shower pump issue. The my house had an incorrectly fitted shower pump which stopped working after I had moved in. Not knowing anything about plumbing or shower systems, it was great to have the issues explained clearly to me, for the work to be carried out quickly. The communication from Plumbox was great and they were always happy to answer my questions. Will definitely use them again.

I have used Plumbox twice for boiler servicing and gas safety checks. It's easy to contact them to make an appointment and they kept me informed about the time the engineer would arrive. The engineer was quick and efficient and explained what he was doing. I recommend Plumbox.

Installed a new whole central heating system (gas pipes, combi boiler, radiator), gas cooker and outside water taps. Really happy with the service and information throughout the process from quote to completion. Michael is very responsive and get in touch with us the whole time.

The fact I like most is that it's easier to get in touch with him (who is in charge) directly and customise your needs even in the middle of the installation, unlike big companies where you ask a question and it takes ages to get back and you only speak to the admin/receptionist and cannot speak directly to the person in charge. You can ask questions and opinions from him. They will explain to you which is most suitable for your needs. During the installation, we requested to upgrade one of the radiators, and install an outside tap at the front of the house, which was done quickly. We also requested to customise the combi boiler and flue location and the way it is attached to the wall and also to upgrade the wireless control to Google Nest, which Michael agreed to do it straightaway.

Price wise, the quote is very reasonable compared to others and the radiators used are of good quality. You will know if you shop around and ask quote from others.

The installation time is great although it took just one more day than expected. But this is due to the fact that they are installing a whole new system (not just replacing old rads or boiler). They explained that they want to get it right in the first place rather than rushing to finish it, and then homeowner faces with issues later down the line. I prefer this way and I can see his whole team is doing their best. When I am writing this review, it's almost 3 weeks since completion. And I don't see any issue like leaks or gas smell or such.

They took extra care during the installation to control dirts and dusts like laying plastic sheets throughout, covering items as needed, vaccuming at the end of each day, etc. They cleared everything after completion including the old hot water tank, loft cold water tank and all old pipes.

Thanks Michael and his team for their brilliant service. Can't recommend enough... :)

We've been using Plumbox for over 10 years, and always had excellent service, and competitive prices. We have used them for boiler installation and servicing, wet room and bathroom renovations as well as general pluming odd jobs. Being OAP's it's good to have tradesmen you can trust.

As a retired surveyor, I have been experiencing great difficulties in finding suitable plumbing, heating and maintenance engineers, since my return from York, six years ago.
These included national and local tradesmen, who generally didn't seem to want my business.
They often didn't repond to my calls, sometimes ignoring them completely, or just not completing their work. satisfactorily.
Having employed Plumbox for the first time, and servicing my boiler successfully, I am hopeful that I do not have to look further for an engineer.

I am glad to wholeheartedly recommend Mr Michael Thomass PLUMBOX, the local Cambridgeshire boiler & plumbing company who in October 2023 fitted an excellent new boiler and did much else besides so as to get my heating-system running like Swiss clockwork in my 1980s four-bedroomed home here in Newnham.
Director Mr Thomas phoned up & came to evaluate my needs for a new boiler within hours of my enquiry, and then his expert Engineer Mr Dan Cutts, fitted it. Dan was a pleasure to have around the house for his cheerful focus on his work that he clearly took satisfaction in doing thoroughly, and all I had to do was fuel him with an occasional cup of coffee and shortbread biscuits. If a new boiler is going to work at its best and the warranty hold good, it benefits from the system flush-through and other sundry works to boiler-piping and flue, particularly on older kit and all these works were included within the quotea quote that was very fair and competitive with other firms [other firms who were far less impressive in their going about a quote]; and let me emphasis that Plumbox was a FAR more attractive option than the impersonal goliath of British Gas. So, if you want old school trustworthy and cheerful pride in their work, then I warmly encourage you to invite a visit from Plumbox.

Right from the start we were pleased with the attention we received from Michael who listened carefully to our requirements and came up with a solution which met what we wanted and was competitively priced.
The Plumbox team worked flat out to replace the old gas boiler and update the electrics on the 2 days we had requested. They left us with some heating overnight and were careful to clean up after each day. We are more than happy to recommend Plumbox for their professional service.

Great company. Was able to fit a major job within a short space of time after the original quote. Very good after sales support when we had a slight problem. A plumber was sent to us within a couple of hours. We have no hesitation in recommending this company.

I contacted Michael at Plumbox to undertake some work in my kitchen refurbishment, which included connecting a new sink and gas hob. Whilst here, they also took a look at a slow-draining sink. They completed the work to an excellent and very thoughtful/considerate standard, which can be rare. Some tradespeople want to get in and out as quick as possible. However, the Plumbox team wanted to make sure they did the job both correctly and neatly. Brandon carried out the bulk of the work, and he was polite, courteous and knowledgeable. I have no hesitations in recommending them, and they will be my first point of contact should I need any further plumbing or gas work done in the future.

Plumbox was recommended to me by a neighbour, and recently did some work renovating our bathroom, replacing a shower tray and cubicle, shower, some taps, bath panels, and so on. Michael was a pleasure to deal with. They did a great job. Bathroom now looks great. Would definitely recommend.
