My gas boiler has just replaced on time and within budget. This company fitted the previous boiler twelve years ago. They always provide a consistent and reliable service. they are easily contactable by telephone or email.

Southgate and Culham continue to uphold very high standards of service. They provided outstanding out of hours emergency help when my boiler failed one weekend. I cannot praise them too highly.

I had an oil boiler and a BoilerMate water storage tank, both nearly 30 years old. After visits from five other heating companies and only two quotes received, I invited Southgate & Culham Ltd to quote. From the first meeting, I knew that this company was the best of the bunch. Advice I had before Keith came all suggested a condensing boiler and no storage tank. Keith said they were good for one person living alone in the bungalow which was the situation I was in. However, this is a three-bedroom bungalow and I do have others staying with me from time to time. Not only that, I intend to sell next year, and I didn't want an adverse report from a surveyor. He submitted his quote, which was not the cheapest but I knew he would do a good job. His team arrived on 23rd June and were finished by lunchtime on 26th June. They were very efficient and worked hard to make sure that I had cold water overnight on the first day. The following day, the new water storage tank was installed and I had hot water for a shower. The installation was very efficient, and they explained clearly what was going to happen. The boiler was installed and working on Thursday morning. They provide a friendly and professional service. They cleaned up each day after work. I am 100% happy with the water storage tank and the boiler and will use this company to service the system each year. I thoroughly recommend this company to anyone needing replacement heating systems.

Nikki again carried out the annual service of my boiler that was installed by Southgate and Culham in 2020; I have received excellent service from the Business from when they installed the boiler and every year since. I cannot say anything more than that they are brilliant.

Southgate and Cullam have serviced my boiler for a number of years, always on time, on budget and always with aftercare. A week ago he installed a new boiler as an emergency ( on his day off ) I can not thank him enough, he worked all day until the work was completed. On the agreed price and with cleanliness and care. He removed all the old boiler and flu etc. Nothing for me to deal with. On completion, he explained the new boiler, handed over the paperwork and advised me he as usual was available for aftercare. Can not fault Southgate and Culham.

My old oil boiler finally died and I needed a new modern boiler. Research showed that Southgate and Culham are Diamond installers listed by Worcester Bosch. Had to wait a while for them to fit me in but well worth the wait as both partners are fully qualified engineers and really know what they are doing. They fitted the new boiler outside my utility giving me more internal space and easy access for servicing in the future. Both partners are friendly and helpful and they easily fitted an extra radiator (which was not in the original specification). They are very clean and tidy leaving the site neat overnight and as clean as they could make it at the end of the job. All the paperwork has been completed in a very professional manner, invoices on time and receipts returned swiftly. I would highly recommend this company, they have over 30 years experience of central heating engineering and they are good people with whom to do business.

Southgate and Culham carried an annual service of my oil fired combo boiler. This is the first time I’ve used them. Their work was excellent. The engineer, a woman, explained exactly what she would need to do, and what snags she might come up against. The work was carried out most efficiently, and we agreed she should replace a part which would normally be renewed annually. She advised installing a slightly more expensive model as it offered better value for money and last 2 - 3 times as long. The boiler and surroundings were left immaculate. Throughout she was most courteous and at pains to be sure I was happy with her work - very important for an elderly person like me! The only tiny shadow in an otherwise flawless experience was a last minute change to the appointment which I did not know about. The engineer arrived some time after the agreed time slot, and apologised that they had not warned me beforehand. But I would unhesitatingly recommend the company.

There's nothing more reassuring than people who really know their trade - Kevin and Nikki are utterly proficient and take a genuine pride in their work; there's never anything remotely second rate about their workmanship or the products they install, it's always absolutely first class. It's massive bonus that they are also friendly and reassuring. Really can't recommend them too highly.

Kevin services our boiler annually and at the last service he advised we were on borrowed time, we decided to have a new boiler installed before winter. The service provided is always professional and we trust the company. Price seemed fair and we trust the company's work. The job was completed as agreed, on time, to a high standard, no issues, great communication during the job as usual. We are very happy with the work performed.

Work was carried out efficiently and effectively - even when a specific component was needed which was not carried by the company, this was sourced. The space left was clean. Given the time spent on a Saturday, the cost of the work was very reasonable. Thank you

Our 20 year old oil boiler was failing and so they quoted and installed a new boiler over 2 days. It was a tricky job but they did it very professionally and kept us updated in a friendly way through the process. Highly recommended family firm.

Southgate & Cullum installed my boiler 9 years ago and did the annual service today. They are always on time and carry out the work efficiently and tidely. Always very friendly. We are retiling the kitchen and changing all electrical fittings one of which was a boiler controller. I asked Kevin to change this during the service which he did free of charge. Very much appreciated and typical of their service. Would highly recommend.

Kevin at Southgate and Culham Ltd is a true professional! Kevin carried out the installation of our boiler in 2019 and it really was an excellent job. He gave us wonderful advice at the time as to the type of Boiler that would suit our house. Kevin thoroughly explained the types of Boilers that would be most suitable for our needs and we are extremely happy with the performance of the Boiler he recommended. He always arrives on time for our annual Boiler Service and is always very cheerful and extremely personable! Kevin always hands over the paperwork which he has completed in a comprehensive manner and explains the Service that he has carried out on our Boiler and is always extremely thorough in his work. We are very happy to highly recommend Kevin's work to everyone and we always receive prompt emails also from Nikki at Southgate and Culham Ltd. We value the fast response we always receive from Southgate and Culham Ltd and know that they are at the end of a phone, should we ever need to make contact. We look forward to Kevin's annual visits for the Boiler Service in the future. Thank you. Tommy and Christine Cain - Swilland
