HOMEOWNERS AND LANDLORDS

Never run out of hot water again

Cylinders are often replaced due to age, faults, lack of capacity for the household or as part of an upgrade to your wider heating system. Whatever the reason, getting the installation right from the start ensures your new cylinder keeps up with your hot water needs.

Installation starts with a visit from one of our surveyors. They’ll take measurements, assess your existing system, and talk through your requirements — and then send a full quotation within a few days.

HOW IT WORKS

What happens on installation day?

Once you’re booked in, the engineer will remove the existing cylinder, install the new one, and connect it to your heating, hot water, and associated controls.

The engineer will complete all necessary safety checks, testing, and commissioning before talking through how everything works. Our admin team will also make sure everything is registered for you, to make the most of those extended warranties.

Had to call Blue Flame out a week ago to fix a leak we had. We aren't on a service contract so we were delighted that they were able to get an Engineer come out to us that same day. Really happy with the service that Callum G provided. Friendly and thorough. Would recommend 👍🏼. Thanks very much!

Friendly and professional engineers. Had a service done and it looks like a slight pressure issue has been resolved along with a noise from the circulation pump! Well happy! Although I think they normally have one engineer for a service, in this case they happened to be together on the day. I'd happily have either one (Ryan or Matt) back if needed regarding my ASHP system.
Thanks guys /Blue Flame.

I’ve hired Blue Flame several times for boilers and plumbing and have always been happy with their work.

Recently they rectified some poor-quality pipework left by a previous builder. Their work was a vast improvement and, during the process, they discovered a cracked sewer pipe the previous builder hadn’t mentioned. By catching this early, Blue Flame saved me from the nightmare of installing a new bathroom only to have to rip it out later to fix a leak.

On one occasion a piece of work had to be redone but I am still happy to give them 5 stars because they took full responsibility and rectified it promptly without any fuss. Also, the staff are consistently knowledgeable, polite and professional. I fully intend to use them for future work.

Excellent service. The receptionist's are extremely polite and helpful. We've started a breakdown cover with them, the Daikin air source heating system was checked and serviced first, Matt the engineer is very knowledgeable and explained everything well. I would highly recommend Blue flame. Thank you guys

Our boiler wasn’t firing up so I called to arrange a visit. However Grant was able to advise via FaceTime. He was friendly and helpful and we were able to resolve the issue. I’m extremely grateful that someone was willing and able to help solve the problem and it means that as a newcomer to the area, I know who I will trust in the future. Thank you so much.

Lovely experience. Chap called Tom went above and beyond and took some additional steps that were beyond the scope to stop the problem happening again

I recently used Blue Flame and they where great. I’m sorry I can’t remember everyone’s name but Chris and another lady came around and inspected our house, and then Lee and Solomon came later to rectify all the items. They went above and beyond for me and I’m really happy I used them. Thanks.
