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!

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.

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.

Great boiler service, the engineer took everything apart and cleaned the inside and changed the seals.He also took a water sample from the boiler which showed the system was dirty and he was able to book me in to get my system cleaned without me needing to do anything.Very helpful and professional.Thank you

I’m a property manager in SW London and have recently started using Heatsy for our gas checks and boiler repairs.The service has been exemplary and their professionalism is second to none.Very, very pleased.

Heatsy completed our boiler repair quickly and efficiently.We called at 12pm and were offered two appointments, 4-6pm that evening or 8-10am the following morning at a lower rate. As it’s winter and mom was visiting from the US we decided to get the emergency appointment.The engineer called and text before he arrived and kept me updated throughout the work.Coming from the states we’re used to great customer service and I must say Heatsy made me feel right at home.Your slogan should be ‘British class with American service’I’ll be telling all the other moms at the next PTA meeting 😊

I’m really pleased with our new boiler, the Heatsy team were very polite and professional and worked until 6pm the first day then finished the system flush the next day.I highly recommend.

I had a combined boiler service with landlords gas safety certificate.The company were very professional and my tenant was very happy with the engineer.All paperwork and certificates were emailed in real time and I could track the engineer which is a nice touch.Four stars as the appointment had to be rescheduled due to over running work.

Perfect service from the team at Heatsy. Lee repaired our boiler in one visit and left no mess, very happy
Jordan L.

Really pleased with the work Heatsy carried out for us.We had a full refurbishment of our home in London and Heatsy managed the central heating part of the job.Overseen by Lee, with our main contractor Heatsy designed and installed a full system with underfloor heating and a Vaillant boiler.
Rob S.
06:05 22 Dec 20
Amazing call out for an emergency boiler repair.The engineer worked really hard to figure out a problem we’ve had for over a year, great service.I’ve given 4 stars because the call centra was closed and I was diverted to a girl her mobile who took a message before the engineer called me back, other than that, perfect!
David H.
08:18 21 Dec 20
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!

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.

Was a bit weary using a new contractor as our usual guy has just retired. We usually try to use sole traders as they’re generally cheaper but couldn’t find anyone who could fit us in.My friend at work recommended Heatsy and I must say they were brilliant and very professional, we will be storing their number.

Heatsy installed a new Vaillant combi for me 2 weeks ago. The install took a day longer than planned but they never left us without heating or hot water for even one night and came back the next day to finish some minor bits.

Heatsy provided an amazing service right when we needed them most.We got home from Ibiza at 6am to find the house freezing and the kitchen flooded, the boiler had burst!The engineer arrived at 7.30 the same day and managed to stop the leak and clean up, the next day he was back to fit a new boiler.Anybody who knows little Venice knows the streets are narrow, Lee met the delivery driver around the corner and helped him with his wheely thing to bring the equipment back and stayed until 8pm to make sure everything was working, I honestly can't thank him enough.Heatsy are life savers and I would strongly urge everyone getting a new boiler to try them.😍
Carolyn S.
07:57 09 Oct 20
I woke up to find the kitchen floor flooded and the boiler flashing an error code.Heatsy sent an engineer that afternoon and he diagnosed a faulty valve, he replaced the valve and repaired the boiler in one visit.Highly recommended.

Emergency boiler installation in West Hampstead.First and foremost I'd like to thank the whole team at Heatsy for accommodating me and going the extra mile to fit me in.My mums boiler had packed up at about 4pm and when I called to make an appointment I was initially offered a next day visit, after explaining to a lovely lady on the phone that my mother was 90 years old and we really needed someone as quickly as possible she said she would contact our local surveyor to see if he could squeeze me in that evening, he could!A chap named Lee called to confirm he'd be attending that evening and even though it was a last minute appointment his survey was reassuringly thorough and professional.After going through our options we decided to opt for a Vaillant Ecofit with a Vaillant controller.He explained that due to the time he was unable to order the materials from their normal supplier to be delivered tomorrow but, he could arrange for the engineer to collect the materials from another merchant and was very honest that this would incur a nominal additional charge as the merchant is a more expensive one.Due to the situation I agreed and paid the deposit to confirm the installation.The engineer arrived at about 9am and worked right through to nearly 10pm to make sure everything was finished that day, the work was very tidy and professional. The engineer was polite and respectful.The entire experience of working with Heatsy has taken a very stressful and worrying situation and made it less so, I'd go as far to say it was almost pleasurable!I would highly recommend using Heatsy and am so grateful for all they have done to help.

These guys were the only ones who were able to figure out why my boiler wouldn't heat past 30oc. I feel like I must have tried half the plumbers in north London before Heatsy, I'll be calling them first next time.
Daniela G.
10:49 20 Aug 20
Emergency boiler repair in Kilburn, the engineer attended the same night and returned the next morning with the new part.Very polite phone staff and professional engineer, would recommend.

10:17 20 Aug 20
We used Heatsy when we had a boiler fault in our by to let in Kensington and the tenants were without hot water.We got through to a lovely young lady who was able to book us as first call for the following day.The engineer arrived promptly at 8am and managed to fix the fault in one visit, yes they are a bit pricey but the service they offer justifies the price and we'll be using them from now on.
Elen G.
12:47 17 Aug 20
Although by no means cheap we're happy to pay a little extra to get piece of mind.The engineers at Heatsy are always prompt and professional and you know exactly what you're getting.

16:24 14 Aug 20
From start to finish Heatsy were a pleasure to work with.We have an old Victorian house in Hendon and needed something that would fit in with our style while also packing enough bite to heat the old girl in the winter months.The system Heatsy recommended not only looks superb but it's also extremely modern, efficient and so much quieter than our previous old beast of a boiler.The Vaillant set up we went with means we can control and regulate the temperature of each room individually from an I Pad and also have continuous hot water on demand.Very impressed new customers.
Florence J. G.
16:31 12 Aug 20
Heatsy came out to us in Cricklewood last night as an emergency call out.Considering the time the chap was very cheerful and certainly knew his trade, a top top performance and we're all very grateful for the service.

15:47 12 Aug 20
Heatsy installed a new boiler and 7 radiators in my Swiss Cottage flat. The booking process was easy and the guys were polite and professional throughout, I would not hesitate for a second in recommending Heatsy to anyone who is having their heating upgraded.
Joseph W.
16:21 11 Aug 20
I can honestly say the engineers at Heatsy are the most professional, reliable and considerate tradesmen I've ever had the pleasure of working with. Keep up the good work.

A massive thank you to Heatsy. I called at 7am the engineer arrived at 8am I was having a hot shower by 9am, amazing service.

I needed 3 gas safety certificates in Hampstead and NW6, Heatsy provided a fast and reliable service.
Jorden W.
12:21 08 Aug 20
After getting 5 quotes and having engineers tell me it's impossible to move my boiler or I'd need to take all my floors up and kitchen out Heatsy designed exactly what I wanted.The guys worked flat out for 5 days straight, I'm so happy I could honestly cry.Thank you Heatsy.
Maria D.
14:10 07 Aug 20
I just wanted to leave a review to say how happy I was with my boiler service in NW8.The engineer cleaned all the bits inside the boiler and did all the usual checks but he also checked the water from the taps and showed me the level of scale in my water and took a sample from the radiators to be analysed.I got a report telling me my system was in good health which is reassuring, it's a level of service I've never had and I'm extremely impressed. 10/10.
Alexander H.
12:07 07 Aug 20
Absolute gem of a find, needed 3 gas certificates done the same day and Heatsy were able to help. The engineer text when he was on his way and did a proper service, not like the BG engineers who do the minimum for a landlord certificate. Gem of a find to keep.
Blake M.
14:46 06 Aug 20
First day back to work after lockdown and my boiler packs up. I called at 6.30am and the lady said they had an engineer booked in Camden that morning and could send to me in Kentish town next. The guy arrived about 8am and was gone by 8.45 and I made it to work by 9.05, highly recommended.
16:57 31 Jul 20
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.
10:31 31 Jul 20
I let a few flats in Belsize Park, Hampstead and Little Venice. Heatsy do the gas certificates and have never let me down, always punctual and the documents are in my inbox the same day. Great service.

16:12 30 Jul 20
Heatsy installed my new Vaillant boiler in St. John's wood about a month ago.The work was top quality and I was particularly impressed with their staunch approach to social distancing, I'd had another firm round to quote and the guy kept trying to shake my hand or get too close, no thank you!
Camila V.
11:21 29 Jul 20
I live in Hendon and needed an emergency engineer, my boiler stopped working and we have new born twins !!! Heatsy sent an engineer at about 9pm and my wife was able to give the kids a warm wash in the morning, thank you Heatsy x.

I had a boiler repair and half price gas safety certificate by Heatsy in North London. Everything was great, they did what they said.

17:12 25 Jul 20
I recently had a new boiler installed by Heatsy in Primrose Hill.I was worried about choosing the correct company but was reassured by the survey process and the attention to detail, not only in the practical checks the engineer performed but also the attentive way the engineer listened to what I wanted.The suggestions were exactly what I wanted, the company took my sons contact details to keep him updated throughout the day and also took before and after pictures to help me.
Edna F.
14:40 23 Jul 20
Heatsy saved the day, 9 emergency same day gas safety certificates in Bayswater, Little Venice, Hampstead and Camden.My clients normal company refused to attend due to Covid but Gas Safe insisted the compliance must still be kept up to date leaving us stuck.After a few frantic phone calls and Google searches we found Heatsy who were luckily able to fit us in, we have another 17 properties in and around North and North West London which we may be moving to Heatsy going forward.
Justin C.
14:17 23 Jul 20
Heatsy installed 8 new Vaillant radiator valves and a new Vaillant ecotec boiler in my flat in NW6 West Hampstead.The work has been completed to a high standard and I can now control the heating individually in each room from my main residence in Cambridge, astonishing.
Merlin G.
09:11 22 Jul 20
John from Heatsy installed my new Vaillant boiler about 2 months ago.We have young children so it was classed as an emergency, John respected social distancing at all times, he wore shoe covers, latex gloves and a face mask. He also used ample dust sheets and brought his own flask of tea.I'm honestly ever so impressed with their professionalism but more so their understanding that with young children we were concerned to have tradesmen in our house.I would not hesitate to recommend Heatsy to anyone.
09:03 22 Jul 20
A first class boiler repair by Heatsy in Hampstead.

14:53 20 Jul 20
Heatsy installed a complete new Vaillant system for us in NW9.We had a new Vaillant ecotec boiler and Vaillant water cylinder with new Vaillant internet controls.They moved the boiler from the basement kitchen to the upstairs airing cupboard with the new cylinder and we couldn't be happier.With 3 young children in the house we no longer run out of hot water half way through bath time even though they fit smaller cylinder than the one we had.
Bessie D.
09:54 18 Jul 20
I recently had a shiny new Vaillant boiler installed by Joe from Heatsy.We had arranged 3 quotes in Camden and 1 never turned up, 1 took about 20 minutes and it felt more like a sales presentation and the last was Heatsy.Lee was very polite and asked me a few probing questions to get an idea of what I wanted, I was keen on Vaillants IQ 837 boiler but Lee insisted I would be better off with an EcoTec 825, which is about £600 cheaper.Joe was very professional throughout the installation and I now have an amazing boiler.
09:38 18 Jul 20
Lee from Heatsy came out to repair our boiler in Islington last Saturday, the price was reasonable and the speed of service and quality of workmanship were second to none.
Nicola A.
16:27 12 Jul 20
Heatsy installed our new Vaillant boiler in Hampstead.The work was carried out to a very high standard and looks fantastic, the engineer worked extremely hard starting around 7 am working right through to about 7.30 pm.
Dora F.
11:18 11 Jul 20
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 a plumber do a boiler repair?

No, Plumbers are not gas engineers. Your local gas engineer may well do plumbing work but if they’re working on your gas boiler they need to be Gas Safe registered.

How much should a boiler repair cost?

The cost of a boiler repair will vary depending on many things, different areas within SE London will have different rates, and with Lewisham being considered a more affluent area rates of up to £160 p/h are not uncommon.

Some larger companies may offer a 12-month guarantee which will increase the price, while others offer just 3 and in many cases no guarantee at all.

If you have an experienced heating engineer from Heatsy, who can spot the fault early and repair it quickly you can pay as little as £99 + VAT with a 12-month guarantee and 5 STAR rated customer service.

How long should a boiler repair take?

Just like the price of a boiler repair, the time it takes to repair a boiler will also vary dramatically depending on what type of boiler you have, the age of the boiler, and the abilities of the engineer repairing your boiler.

Most faults should take an experienced engineer no more than an hour to diagnose and then another hour to fit the parts if needed.

What Does Heatsy Do?

You know that feeling of waking up to a freezing cold house, finding out the boilers broken, and the dread of having to face an ice-cold shower on a wintry Monday morning?

Well, we fix that.

We help to make your life more comfortable by giving you a hassle free boiler repair service for a reasonable price with proven results that are guaranteed to last, in fact, we've got tons of 5 star reviews from our other happy customers.

All our installations and boiler repairs come with an iron-clad 12-month guarantee.

Our affordable boiler repair services start from just from £80 + VAT and if we can repair the fault within 30 minutes without any parts then that’s all you’ll pay.
