Boiler Installations
- We offer a 10 years manufacturer’s warranty with many of our installations.
- All of our work is Guaranteed
- If our supplier has the boiler in stock- we can be there next day!


What We Offer
Unlike some of our competitors, we won’t try to persuade you to do “unnecessary” work.
At Mizzen our promise to you is to give you honest impartial advice & all the information you need to make the right decision based on your circumstances.
We firmly believe that by giving you great value, and great customer service, you be a valued customer for years to come.
Boiler Servicing
Manufacturers recommend servicing a boiler annually by a registered gas safe engineer to keep the warranty valid. Like a car, a boiler’s service record must be updated, as manufacturers check this if issues arise later.
Our engineers clean internal parts, ensure maximum efficiency, and inspect all elements, including filters.
A Gas Safety Certificate, or CP12, ensures gas appliances like boilers, hobs, and fires work safely and efficiently. Landlords must have one for rented properties, while homeowners are advised to get one for safety and insurance purposes.


Underfloor Heating
In new refurbishments & new builds underfloor heating is often the first choice for a more balanced heating of the home. You can have control of specific floors and even rooms or zones.
Everything can be pre-set with the latest smart controls. As technologies change underfloor heating can also be connected to and run by air source heat pumps. Although not suitable for all projects- where possible these are a very good green alternative as your primary heat source.
Smart Controls
As the government continues to hit its targets of lowering carbon emissions in the UK, smart controls have become a big part of that initiative. Boiler plus was bought in so new combi boiler installations with compliant controls could reach 98% efficiency in some cases.
Other models like Tado, Nest, Hive either learn your movements through the location settings & connection to your phone or connect to the homes broadband & adjust the heating in the home in accordance with the weather conditions. You can also manually control all of these on your phone.

Mizzen have been servicing my boiler since 2020. I called them in to change my megaflow type system to a combi boiler. The manager Charlie talked me through my options and gave me his recommendations and explained exactly what would happen. His colleagues Alan and Harrison were great and were experts in boiler fittings and pipework. If pipework were an art, they would be Michelangelo and Da Vinci. Such skilled and competent workers, truly committed and taking pride in their work. Their work was neat and careful, not rushed or slap dash. They also fitted my new radiator and new shower. Lovely Mark came to take away the old boiler, tank and all of the rubbish the next day.

Our boiler was broken last week. We urgently needed a new boiler instalment as we have a toddler in house and are soon expecting a new baby. Mizzen has booked new boiler instalment in a short-notice. They came and did pretty clean and good work. I worked with Mizzen for a couple of other repairs in house before. They are always reliable, friendly and providing quality service. A safe pair of hands and highly recommended.

Job well done. My parents found Harrison to be most polite, efficient & tidy when replacing a kitchen trap. Would thoroughly recommend Mizzen.

I had a major leak from my boiler during heavy rain fall. Charlie talked me through what I needed to do, out of business hours. What a gem. I ended up requiring a new boiler. All priced up, and Paul and James fitted it a few days later. Neat and tidy. I wouldn’t hesitate to recommend them, in fact, I already have. They are fair and reliable. Thanks lads.

Very good experience with this company. The office was efficient and helpful. The visits were arranged with a minimum of delay.
The work was undertaken by a plumber called Levi who was very diligent and logical solved the problems in our underfloor heating system. He provided comprehensive advice on how to manage our now repaired heating system.

Charlie and Mizzen Construction are AMAZING!!!! I have had them do all my Boiler, plumbing and Kitchen installation for the last 17 years. I worked with many – but they are definitely the best by far! Always, prompt and friendly, he and his team of plumbing/heating experts are second to none. I highly recommend Charlie. 10/10

Great communication from the initial enquiry. Harrison arrived on site promptly, he was really polite and professional, and we were really pleased with the work carried out. I will definitely be using Mizzen again in the future! Many thanks.

Firstly, huge apologies for such a late review. Charlie and the team did our bathroom months ago.
It was professional from the get go. Charlie was superb at advising and keeping costs realistic. He explained things through that would make the bathroom less prone to issues.
Gary and Matthew ripped the old bathroom out quickly and made the space good then installed everything really efficiently. Then the tilers came and did a fantastic job.
Gary came back once done to move a couple of bits and was exceptionally professional and skilled.
Finally, we had a leak issue which was a quick simple fix and was done about a week or so later.
Months in now, so happy with the bathroom.
I’d totally recommend Mizzen because from start to finish, it was a pleasure and the work is to a very high standard.
