I phoned Chris on the monday as a new customer and he came out to me that same week, disgnosed the issue then returned a few working days later and fixed it in under 2 hours. Really pleased with how quickly he was able to sort it and the boiler has been great since - thank you!

Excellent service, thank you Chris. Boiler was leaking, went online with CheckaTrade and found local Gas Boiler engineer CMC. Called Chris who answered immediately. I explained the boiler issue and he came round within 20 mins. Promptly diagnosed the problem and repaired it just as quickly. Polite, courteous service and knowledgable. A pleasure to deal with and competitive rates. I will use CMC Heating and Plumbing in the future. Highly recommended.

I asked Chris to service my mum's boiler which was in a tricky location in a kitchen cupboard. Despite this he did not charge any extra even though it was very difficult to access as half the cupboard had to be dismantled. He also looked at a leaky drain-off valve and I was pleased when he said it just needed tightening - some others may have charged extra or made out that additional work was needed. I am very pleased with the service he provided and would use him again without hesitation. The price was very reasonable.

Chris replaced our broken boiler. He came out promptly to quote for the job and was very knowledgeable and transparent about the work that needed doing. The price we received was very competitive and we didn't hesitate to use Chris as he had done a couple of other jobs for us in the past. Chris is always very friendly and polite and did an excellent job. Above all, his communication and timekeeping is great throughout, which isn't always the case with other tradesmen!

Very Competitive quotation given for the job and accepted. Chris has been our heating engineer for several years and so we had no doubt that he would do a very thorough job. His attention to detail is first class and the entire job was undertaken competently with all the requisite checks and explanations to the householder undertaken. In addition Chris wore a face mask (at my wife's request as a Covid 19 precaution) throughout the work. I have no hesitation in recommending him as a very sound and reliable heating engineer,

Chris arrived at the time agreed and was extremely friendly and courteous. I was very impressed that he removed his shoes (most tradesmen do not do this). At all times whilst carrying out his work, he kept me informed of what he was doing. This is very reassuring from a customer point of view. You can clearly see how passionate Chris is, and how thorough he is when carrying out any works. I would not hesitate to use him again in the future.

When I found water seeping out across the kitchen floor I rang a few plumbers for help. CMC Heating was the only one who answered, the rest didn't even return my call. The Plumber said he would visit within a few hours and true to his word he came later that morning, found the problem, and fixed the leak. He was friendly, courteous and worked cleanly and efficiently. I was very impressed with his professional attitude and would definitely recommend him.

Smart checks

Before you hire a plumber

Agree the call-out fee, the hourly or fixed rate, and whether parts are charged on top — in writing — before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced — get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade — not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
