Brilliant service. I booked my boiler repair online, received great communication and confirmation of my appointment. I got a text telling me the engineer was on route about 30 minutes before he arrived, he kept me informed about what was going on and after I agreed the price he fixed the boiler in one visit. You really do get what you pay for, I’ll be using them again, not too soon hopefully.

Called up in the morning as my boiler wasn't working. Despite the engineers van being broken into, he still said he would come out as my 1 year old was in the house.The engineer Lee turned up on time and was a very genuine guy, very helpful and happy to answer any questions about the system.Even though he was unable to fix the problem on the visit to provide heating, he left and returned with some electric heaters for the house free of charge!Turns out I may need a new heating system too which I'll gladly get installed through this company!
Lee H.
Excellent customer care, polite and helpful engineer, clear estimate with regular updates. Would highly recommend this company-backed by British Gas guarantee on all work.
barbara H.
I would highly recommend this company to anyone. Their engineer was prompt, extremely hard-working, friendly and professional.All rubbish plus packaging for new boiler promptly taken away, leaving the area in which it was temporarily placed cleaner than it was before! A truly hassle-free experience.

Lee from Heatsy was brilliant, responded in quick time and alot cheaper then other major companies. Not only did he find the fault with my boiler he was able fix it quickly. Will definitely recommend to my friends
Jonathan H.
Amazing friendly, efficient service at a very fair price. I called Heatsy to supply and fit a new wireless room thermostat and heating control unit at a rental property after being quoted an extortionate amount by another company. Job was finished within 3 hours of initial call. Happy tenant and almost half the cost of what I was quoted previously. Would highly recommend.
Denise T.
Quick service even on a Saturday. Temp fix followed up by speedy full fix at a reasonable cost. Will definitely use again.

Lee and his team replaced our boiler and I would highly recommend Heatsy to anyone. They were professional, courteous and very punctual. Lee is very responsive to our enquiries and he explains everything clearly. Heatsy offers fantastic customer service as Lee kept checking with us to make sure everything works properly after the installation. We are very happy with their service and we’re looking forward to having Lee back next year to service our boiler.

Very helpful & friendly service, very good rates also.
Linda W.
Fantastic customer service with a range of options and fair, transparent prices. We were kept well informed at all times and the team was very polite, tidy and considerate. Even after the boiler was installed, we had a post-installation checkup to make sure all was perfect! Have had two boilers in other properties installed and this was by far a quality and fair service above all!
Karen R.
I would highly recommend Heatsy to anyone looking for a boiler service. Lee arrived promptly and carried out a thorough inspection of our boiler. He recommended a few problems that needed fixing (new flue, magnetic filter and system flush etc).I then rescheduled an appointment with Heatsy to carry out the recommended work. Lee arrived on time each day, kept me informed of his progress, he was very tidy and finished the work within the scheduled time frame. He was also very accommodating and installed a thermostat at short notice.Since the service, my boiler is working more efficiently and my home is heated in no time. They also sent me a follow up email to make sure everything was working ok. Their service was first class through out. I am a very happy customer and will definitely use them again.

Lina A.
Hello, I am Fadi. The team came to my house to replace the boiler. They did a wonderful and professional job for the boiler. I thank Mr. Lee for this work. We wish you continued success and progress.
Fadi A.
Was extremely helpful and explained what needed doing and was honest about what I needed to consider. Once he had finished and I messaged with an enquiry my engineer offered to come back and have a look. They sent a follow up message to ensure everything was still working and to check it was ok. Would definitely use again.
Sarah L.
Amazing service and repair, thank you Lee and team! You were professional and did a fantastic job and the repair has made a world of difference!! I can highly recommend!
Graham P.
Contacted Heatsy as they were recommended via Local Heroes website and every contact was positive - boiler was diagnosed as requiring replacement which was all carried out within days of diagnosing - Lee kept to promise to replace boiler within two days and completed the job. All relevant paper work and certificates were issued. Very impressed.
Steve H
Having had a bad experience with a well known Plumbing company who didn't deliver and really ripped me off I was recommended Heatsy by my builder and I'm so glad I was. Reliable professional and importantly honest I have used them a number of times in the past few months and service has remained consistent at all times. I'd recommend to anyone.
Liz C.
Heatsy installed a new heating system for me in Hampstead.I was particularly impressed with the survey, after 3 engineers telling me I needed a combi without asking me any questions the guy from Heatsy was the first one who asked me what me and my family needed which, it turns out was NOT a combi.We now have Vaillant boiler and water tank with an outdoor sensor, the engineer was very knowledgeable about energy efficiency and which controls would benefit us the most.I'm extremely impressed and would highly recommend.

Can plumbers fix boilers?

Anyone who works with gas in England and Gas must be Gas Safe registered.

Because many aspects of plumbing and central heating are similar, often heating engineers will also do plumbing work, but plumbers who are not Gas Safe registered are not allowed to work on your boiler or any other gas appliance.

So a heating engineer can undertake a plumbing pipe repair but a plumber can't address boiler breakdowns.

Always ask to see the engineers’ ID cards to make sure they’re legal and suitably trained to work on your gas appliances.

Should I repair or replace my boiler?

The decision to get your heating fixed or have a boiler replacement when it’s broken is dependent on the age and required work.

Our honest advice is to never consider replacing a boiler that’s less than ten years old, occasionally we find boilers that are so badly installed we do advise customers that a replacement would be more cost-effective, but this is very rare.

Can I fix my boiler myself?

Not really. If there is a small problem like low pressure you can top it up yourself which may temporarily get the heating working again.

If anything, external needs repairing, the pump, a radiator etc and you’re comfortable in doing so, there is no legal objection to you attempting the heating system fix yourself.

But, if you need to remove the case from your appliance, interrupt the gas supply or change any parts in a gas appliance, you need to be a Gas Safe registered heating engineer.

There are lots of suitably qualified companies offering boiler repairs Sutton, so you shouldn't need to fix your heating yourself
