Mark was able to come and provide a quote the same day following an issue with our boiler, and was able to schedule the work for completion the same week. John and Harvey were great, worked really hard to get the job done quickly and the quality of the work is excellent. Moreover, the quote was extremely reasonable and the aftercare has been excellent. I'd highly recommend Mark and team.

I cannot speak more highly of South London Heating. Mark attended promptly to quote for the work, sending through the quote the following day and kept in contact during the work. John and the other engineers completed the work to a high standard, and showed flexibility to get the job down when our requirements changed. Sara offered great customer service from the office always dealing with phone calls promptly and courteously, and dealing with invoices, warranty and other paperwork very efficiently. Overall competitively priced, reliable, customer focused and local.

Mark with his team of Paul and Ryan, did a great job installing my new boiler, putting new tanks in the loft and a new hot water cylinder in the airing cupboard. Mark's design worked well for a mid-terrace house with limited outside wall space, utilising the existing airing cupboard and taking the flue up into the loft and out through the roof. British Gas had been unable to suggest anything when they came so Mark's "can do" problem solving approach was much appreciated. The work was carried out with smooth efficiency and a change I wanted during the job was accommodated with good humour. They were a delightful firm to work with, thoroughly professional, who I would recommend without hesitation. The price quoted was also extremely competitive.

Booked and annual service for the boiler Mark installed last year and had a stop valve fitted on an outdoor water supply. Mark kept me informed about the time he would arrive, gave the price up-front and carried out a thorough,job. He re-set times according to my needs and bled all radiators. The extra job of fitting the stop valve was fitted quickly and efficiently.Mark is polite, efficient had works to a very high standard

This is a very professional company. Mike came to give us a quote. Later on answered all our questions promptly and when we had a query as to the positioning of the pipes he even came back again on a Sunday to discuss this. The work was done efficiently by Luke with the minimum of disruption. We have been enjoying our new boiler. Highly recommended for their prompt service, efficiency and courtesy.

Mark replaced a boiler and hot water cylinder. He arrived as planned and the job was done exactly as quoted. There was a small glitch afterwards with the boiler but Mark came back and sorted this out for us. He also did a small extra job for no charge which I was very happy about. All in all would highly recommend.

We had new electrical consumer units installed (2) which resulted in the boiler tripping them when it fired up. The electrician could not cure the fault so we contacted SLH who had originally installed the boiler. SLH saw us the next day and promptly found and cleared the fault. Courteous as ever, this company is a pleasure to deal with. Highly recommended.

Mark was a great help. An old boiler had finally failed a day before we were to move in to our new house. Mark came out within 24 hours of us contacting him and was able to fit a new boiler - re-siting it as requested in the process - within the next 48 hours. He talked us through our options and, I believe, was objective and unbiased. He was perfectly courteous and punctual. When we had concerned about a couple of our radiators (because of work by someone else), Mark quickly looked into and fixed the small issue at no extra charge. I recommend him without hesitation.

Installation of a large Worcester Bosch boiler and full system flush. Done in less than a day by Mark and his assistant. My house left clean and tidy and rubbish cleared. Very competitively priced. Mark is a very pleasant man who gives good advice. This was the second boiler he has installed for me. Would not hesitate to recommended.

Goodbye Trusty Alpha Boiler Hello Worchester Bosch

Found South London Heating Ltd details from the Worchester Bosch accredited installers webpage as my usual gas engineer was retiring and my trusty Alpha boiler was on its last legs. Mark and his engineer Luke who did my installation cannot be faulted. They arrived on time were pleasant and polite and clean. Good staff make a great company and I am sure Mark appreciates his. Mark provided the information I needed to decide quickly and with no pressure. I have a building construction background and would definitely recommend them to work on my projects. Their high marks from other customers and myself is well deserved.

Mark visited within an hour of my phoning him. He explained the work that would be involved, how long it should take and gave me a verbal quote followed by a written one later that day. He managed to schedule the job in very quickly and arrived promptly on the date with his engineer, John. The old boiler and two radiators were removed with very little mess or disturbance. The new boiler and replacement radiators were efficiently installed and are proving very satisfactory. Mark also explained how the system worked. I highly recommend Mark and his company and will definitely use them again.

I originally wasted a lot of time getting a quote from British Gas. They send round a salesman who not only takes for ever to do the quote but over time I realised didn't really have the technical knowledge to provide a reliable quote. South London Heating provided a quote in hardly no time and carried out the work on time and to specifications. They are also considerably cheaper than British Gas. So I am more than happy to recommend them.

Radiator Leak

Mark installed our new boiler professionally about 3 years ago. Since then it he has serviced the boiler annually and I must say, it is running like clockwork. We recently detected a leak at one of the living room radiators and called Mark for help. He made time in his very busy schedule to come round very quickly to fix this problem. He is the best heating engineer we had in more than a decade. He is the reason why we would never consider going back to a British Gas maintenance contract.

I used South London Heating after the previous plumber I contacted failed to show up. Mark arrived promptly and quoted to remove a radiator and install another on the opposite wall. It was a fiddle to do due to hidden plastic piping but they did an excellent job. They concealed all the piping and did the work quickly with minimal disruption. I wouldn't hesitate to use S.L Heating again and can thoroughly recommend them.

South London Heating were amazing! My boiler kept running over pressure and leaking out the PRV outlet pipe. It was freezing and we had no hot water. The engineer came round within 2hrs of phoning them, re-pressurised the expansion vessel and got the boiler working again. Jack, the engineer was very friendly, professional and trustworthy. Previously that day, I had another engineer come round who said the expansion vessel and the PRV needed replacing and quoted me £350 for the work. Good thing I got a second opinion, eh! ... thanks SLH, you're a life saver :-)
