London Heating Expert Reviews 

Mohammed at London Heating Expert provided a first class, professional service from the start. He turned up on time, provided a swift assessment of the issue, and offered a variety of solutions and costs. I chose the installation of a new combi boiler for which I didn’t think as a second floor flat there would be enough water pressure but Mohammed worked out a way to add a pump into the system to give me powerful water pressure and the combi boiler I wanted. Mohammed was always courteous, hard-working and efficient. Working late into the night to get the job done properly and on time. I couldn’t recommend him more. His prices too were very reasonable. If you have a central heating or boiler issue in London, he should be the first person you call.

Really professional and efficient as well as warm and helpful. I would not hesitate to recommend to everyone I know.

Excellent service for new Vaillant boiler installation. Very caring , came right on time and left late when job was finished. Super professional and easy to deal with. Sent me quote in half a day and was at the house within 36 hours with new boiler. Really good job , very clean and neat. Would definitely recommend

Efficient and polite service carried out with the minimum of disruption. tidied up after themselves at the end

We had 4 engineers from 2 major companies to fix our boiler, which was dropping pressure on a daily basis. The first mentioned there was a leak in the system, and cannot fix it. The other company ruled out a leak, and said it was our heat exchanger: on a boiler less than 8 years old. Between all 4 engineers, I would say they spent a combined 1 hour; one was in for about 10 minutes

Mohammed Ali came and actually investigated the boiler and confirmed the heat exchange was fine. He believed after extensive review it was a leak. He wanted to test it and, if confirmed, fix it in a follow up.

It was indeed a leak, and he came back and resolved it. I am writing this more than 48 hours later, and I haven’t had to top up now for 96 hours!

Thanks to Mohammed Ali, we saved a ton of money. Thank you for your professionalism; you will be our first point of call for any future boiler issues.

Thanks mohammed for fixing my boiler. Excellent service as usual

Superb service from start to finish. I will be recommending and using Mohammed again if necessary as he is a real expert in his field and never gives up! This was a complicated job but all sorted now!

I called London Heating Expert for two problems: 1. My gas and electric bill was outrages, as I thought my central heating never turns off
2. Hot water pressure pump sometimes not engaging into action.

Muhammad arrived on time, explained to me very patiently and in details what could cause it, and he found a faulty valve in 2 minutes. He has a spare one in his van and he finished replacing it and testing everything 20-30 minutes after.
As for the water pressure pump, after looking closely at the problem, he suggested that I have the wrong pump and replacing it will cost too much, so he showed me how to work around it, saving me time and money.

He is very professional, reliable and nice. So I have also asked him to upgrade my thermostat to the new Hive. He brought all the parts with him, did the installation and made sure it all works and that I know how to control it.

I highly recommend calling him for any water/heating related issue!

I booked Mohammed for a power flush, as my rads were not getting hot and the boiler kept cutting out. Mohammed arrived exactly on time and checked out the boiler. He carried out the Power flush plus all the other technical checks on the boiler. Job Done! Mohamed gave me Excellent advice on the Boiler and what caused the problem. If you are looking for somebody to do anything related to your heating or plumbing just Call Mohammed. He is very meticulous and you can rely on him resolving and fixing the problem. I wish I had known about him years ago. He's Brilliant!. From Sundeep

My boiler stopped working all together, booked a same day slot on their website, Mohammad came over and fixed it entirely in under an hour. Was super informative and helpful when showing me what had happened to it! The best hands I could have asked for!

Professional and Tidy.

Great job, completed on time and within budget. Thank you, I definitely would recommend him and use him again.

The technician, Mohammad, has been incredible. I had my boiler broken for 5 days and freezing at home. On the day we requested him to come he was fully booked. However, as I was desperate, he came very late in the evening (11pm) and didn’t leave until the job was done and everything was working again (he left at 2:30am). I would recommend him anytime!

We have worked with London Heating Experts on multiple occasions and they have been helpful, professional and experienced in all instances. I would highly recommend them to anyone seeking help in Mechanical, Electrical or Plumbing fields.

In January 2024, Mo installed a new boiler and new controls onto a complex system for us. He did a brilliant job. In 25 years, I have never come across such a willing, able and honest technical supplier. His services are 100 per cent recommended.

After two weeks without hot water and heating in mid January, three engeneers and 5 visits, Mohammad Ali diagnosed and fixed the problem in few hours. Very professional and knowledgeable service indeed. Highly recommend.

Mohammed came to my house to do the annual service on my boiler. I found him very polite, helpful and knowledgeable.
Mohammed did amazing job - more than any other engineer.
The heating system now is working smoothly and efficiently.
I highly recommend Mohammed's services to those who want extra value for money from such a delightful person.

Really great service - really cared about fixing a complicated problem, finding reconditioned parts where new ones weren’t available etc and lovely to deal with - highly recommended!

I had an amazing experience with Mohammed who quickly resolved a heating issue with our boiler within 10minutes of being onsite.
This is after 2 plumbers appointed by the insurance company told me I needed a new boiler and a power flush.

His professionalism, expertise and knowledge, and commitment to customer satisfaction were outstanding! VERY Highly recommended!!!

I received the service on November, my issue was a complex boiler problem, and he did a thorough examination of the heating system and informed me about the whole process, risks and costs. Finally he only fixed what was needed and did not push me for extra costs. I totally recommend him.

Very knowledgeable
Very professional
Reasonable pricing
