How much do boiler repairs cost in London?

How we chose

1. PH247

Location: 27 Old Gloucester St, London WC1N 3AX, United Kingdom

Contact: +44 20 3764 2713

Operating hours: Open 24 hours

Website

After diving deep into the world of London plumbing and heating, we stumbled upon PH247, and honestly, we’re impressed.

One of the first things that caught our eye was their lifetime labour guarantee. It’s not every day you see a company stand behind their work like that. It speaks volumes about their confidence in their technicians and the quality of their service.

Their boiler repair services start at a reasonable £114, depending on the job’s complexity, and they sweeten the deal with exclusive discounts.

But what probably makes them stand out is that their new clients can get 5% off, while repeat customers enjoy a 10% discount. It’s honestly great to see a company that values its customers and makes top-notch services affordable.

We also love that they’re open 24/7 so that no matter when your boiler decides to act up, they’re ready to respond. 

In terms of online services, they also excel with a user-friendly website where customers can easily book appointments, request callbacks, and even engage in live chats for immediate assistance. 

We can’t forget to mention that they also provide detailed online manuals and resources to help clients understand their systems better and troubleshoot minor issues themselves​.

Diagnoses and fixes issues quickly

“I recently booked James and was extremely satisfied with the service. Communication was easy, and he demonstrated professionalism and expertise throughout the job. James quickly diagnosed and fixed the issue, using high-quality materials and leaving no mess behind. Communication was clear and transparent, with no surprise costs. I highly recommend James for their outstanding service and professionalism.”

Explain the problem and solution in detail

“LJ came to fix our heating system as the boiler was turning off regularly with an overheating error. He quickly identified the issue was actually with a filter downstream that was backing water up into the boiler and causing overheating. I particularly like the fact he took the time to explain what was wrong and why the fix we have gone with is better than alternatives so I could make an informed decision. LJ obviously knows his stuff and is a really nice guy as well. Would happily recommend to anyone.”

2. HK Boiler Repair London

Location: 3, Omega Works, Harringay Warehouse District, London N4 1LZ, United Kingdom

Contact: +44 7950 963066

Operating hours: Open 24 hours

Website

So we’ve been doing some more digging into the London boiler scene, and another name that keeps popping up is HK Boiler Repair. They’ve been around for over 15 years, which tells us they must be doing something right.

And from what we’ve heard, their team is the real deal – all their engineers have at least 10 years of experience under their belts and are Gas Safe registered. 

One thing that really caught our attention is their pricing. They start their same-day repairs at £99, which is pretty darn reasonable compared to some of the other quotes we’ve seen around town. 

And the fact that they offer a 12-month warranty on all their work is a major bonus. It just shows they’re confident in the quality of their service and willing to stand behind it.

Another big plus is their 24/7 emergency service. They also offer a whole range of other services, from boiler installations to gas safety certificates, making them a one-stop shop for all your heating needs.

Now, we have to admit, we’re a little iffy about the fact that you can only book appointments by phone or WhatsApp especially since they have a user-friendly website. But if you’re in a pinch and need someone to come out ASAP, that might not be such a big deal.

Diagnoses and recommends best course of action

“Very happy with HK Boiler’s service. Called them for a leak on my boiler, Simon was able to come check it out same day, diagnose the issue and recommend best course of action. Thankfully just a few loose screws so no parts or anything major needed which is always good news. Will definitely be booking a full boiler service with them and highly recommend for urgent repairs!”

Corrects issues from previous engineer

“OMG. Simon from Heat Knights was brilliant and fixed my boiler (which I thought was definitely broken given its age). Can’t thank him enough! He came to inspect the boiler within 20 minutes, fixed some issues with another engineer I had asked to look at the boiler earlier today, and fixed my radiators. Very impressive, prompt and professional. Thanks!”

3. PCH Boiler Repair London

Location: 39 Warrington Cres, London W9 1EJ, United Kingdom

Contact: +44 7769 555030

Operating hours: Open 24 hours

Website

With over 15 years of experience, PCH Boiler Repair London has truly impressed us with their range of services. Catering to all makes and models of domestic gas-fired central heating boilers, including popular brands like Vaillant, Worcester Bosch, Viessmann, Baxi, and Glow Worm, they’ve definitely earned their spot on our list.

When we looked into their pricing, we were pleased to see they charge a fixed rate of £95 for boiler repairs, which includes the call-out charge and labour, with parts billed separately at cost. 

They’re also available 24/7 for emergencies. So, if your boiler decides to go kaput in the middle of the night, you can count on PCH to come to the rescue.

In addition to their emergency services, PCH provides routine maintenance and installation services. They specialise in high-efficiency condensing boiler repairs and installations, as well as central heating system installations. 

Now, we’re not going to lie, their website isn’t the prettiest thing we’ve ever seen. It feels a bit dated, and there’s no online booking option, so you’ll need to call them for your boiler repairs and emergencies.

Provides knowledgeable and truthful advice

“George is such an excellent, decent person to deal with. Extremely trustworthy, with high integrity, very knowledgeable and telling the truth! We contacted him on a Sunday morning as our boiler failed to work and he performed an on line diagnose and came on site soon and provided a number of options for us with each pricing options. All very sensible and we choose one so he didn’t the installation next two days. All processes are pleasant and we will keep long term relationship with him for future needs and I would recommend to anybody who is looking for help. Regards, Bill the happy customer.”

Acts in the customer’s best interest

“We contacted George in an emergency on a Sunday evening when our old boiler suffered a major failure – within 45 minutes he was at our property, ensuring everything was safe. Within 48 hours, he fitted us a new combi boiler. His buying advice was excellent – we felt like he was acting in our best interest throughout. He was meticulous during the installation and took the time to explain the new boiler and thermostat to us. He was prompt, friendly and overall a pleasure to have in our home. We would highly recommend him and look forward to seeing him again during its servicing.”

4. London Heating Solutions Ltd

Location: 348 Caledonian Rd, London N1 1DU, United Kingdom

Contact: +44 20 7607 7171

Operating hours: 

• Monday to Friday – 7:00 AM to 7:00 PM 

Website

London Heating Solutions Ltd. piqued our interest since it’s a family-run operation, and they’ve got over 20 years of experience in the heating game. 

What we particularly love most about them is that they use high-quality components, and all their repair work comes with a 30-day labour guarantee and a 1-year parts guarantee. 

And they don’t just do repairs – they also offer maintenance plans and install energy-efficient boilers that can save you money on your energy bills. 

We’re also big fans of their customer-centric approach. They offer free quotes, extended guarantees on new boilers, and even flexible monthly finance options. They clearly want to make things as easy as possible for their customers.

Now, we’re not going to lie, there are a couple of things we’re a bit iffy about. We wish they operated 24/7 because you never know when your boiler might decide to act up. 

And their pricing isn’t as transparent as some other companies we’ve seen. You have to call or fill out a contact form to get a specific quote, which can be a bit of a hassle.

Offers quick appointment for boiler leak check

“I called to check for leaks in my boiler system (9 years old and out of warranty) as hot water was going in/out. They offered me an appointment quickly, and the engineer was on time and identified the issue in 15 minutes. Just a few days later, they returned with the repair parts and the work was again finished promptly. No further issues with the boiler since – a relief as the winter sets in! Highly recommend them, professional, timely, and cost-effective.”

Julie Delongchamp, Google Review

Provides a great overall experience

“Had a really great experience with London Heating Solutions Ltd, who managed to come in and fit a new boiler in no time and at a great price. Sean and Connor are really top guys – really friendly and super experienced, as well as always honest about some of the potential issues that might pop up and how that might impact the job and costs etc. Luckily it was a simple installation in the end, but I appreciated that there would have been no surprises. Great job guys, will definitely be coming back in future!”

5. Citywide Boiler Repairs

Location: 5 St Ervans Rd, London W10 5QX, United Kingdom

Contact: +44 20 3892 8545

Operating hours: Open 24 hours

Website

Citywide Boiler Repairs has definitely earned a spot on our list, and for good reason. If they can’t fix your boiler, there’s no fee. They even back up their work with a 12-month guarantee, which is a big plus for peace of mind.

We also like that they’re part of the many boiler repairs that offer 24/7 emergency service. And from what we’ve heard, they’re lightning fast, often arriving within 30 minutes of your call.

We even talked to a few customers who mentioned that Citywide prides themselves on fixing problems on the first visit in 90% of cases. This really minimises inconvenience and gets your heating back up and running with minimal disruption. 

It’s worth noting that they don’t put their prices right out there on their website. But they do offer free quotes, so you can easily get an idea of what you’ll be paying before you commit to anything.

But we have to give them props for their blog section on their website. It’s full of helpful tips and advice on everything from choosing the right boiler to troubleshooting common problems. 

Completes installation of new boiler to a high standard

“I had a problem with my boiler and called Pasha, who was able to come and diagnose the issue the same day. He had a great manner about him, was polite and honest, and knew the boiler and what the problem(s) was very well. We decided on a new boiler (no pressure from Pasha on that at all), and the work was completed to a great standard with a colleague. Pasha made sure to find us good deals on different reconditioned parts to keep costs down too. We would be delighted to contact Pasha again if we need to.”

Daniel C, Google Review

Performs thorough inspection and cleaning of boiler

“We have used Pasha twice, once for a boiler fault and then for a plumbing job ( wash basin tap replaced). Pasha made a thorough inspection and clean of our Worcester Bosch boiler with an intermittent problem , he gave detailed explanations of what he had done and future possible issues- the problem seemed cured but began to leak, Pasha came back and immediately identified the problem as being his fault and no charge. Very happy to use him again.”
