Superlative - can’t recommend Southgate & Culham highly enough

What an amazing couple - Kevin on the installation, Nikki (mostly) in the office and on occasion coming over to lend a hand, and tutor me in the finer points of my smart system. I had a complete new heating system put into a newly connected gas supply in a big older house. The house threw up a few unexpected challenges and Kevin - a true problem solver and lateral thinker - came up with some very clever solutions to deal with them. Kevin also deftly minimised the disruption, kept me in hot water throughout through clever phasing of the work and finished ahead of time. Above all they are both really lovely people with very high standards -considerate, thoughtful and knowledgeable. When I found myself in an unrelated crisis, they were quick with suggestions and offers of help. I found Southgate & Culham through the Which? trusted traders site, and I could not have found anyone anywhere that I could trust more. I am a single older woman and a long-standing member of Which? and am very grateful to have been able to rely upon their expertise, their local knowledge, and their kindness. I cannot recommend them highly enough. And I love my new heating system, which delivers everything Kevin said it would. My dad would approve of him.

Southgate and Culham replaced our aging oil boiler with a Worcester Bosch unit and did an excellent job from start to finish. Throughout the two day job they were friendly, efficient and courteous. We decided to redesign our utility room where the new boiler was going to go and Kevin was really helpful with pipework routing to make the new room easy to tile and paint, nothing was too much trouble. Will definitely use again for servicing and future works. Would recommend highly.

Southgate & Culham Ltd installed my boiler in 2019 and have also serviced it every year. A small problem occurred and they arrived at my property within 40 mins of my call. Came back next day to check everything was fine. Excellent service and would recommend the company. Fast efficient and friendly.

Heat exchanger failed on our 13-yer old boiler and so we were without hot water and heating. Within two days of diagnosing the problem, Kevin had stripped out the old and fitted a new boiler. Brilliant!

Our plumber recently retired so it meant we needed to find a local plumber. Our property is only 10 years old but problems can and do arise and not having a reliable plumber is not a good idea. I found Southgate & Culham and have now used them 3 times in the last 4 months. They have given excellent service over 3 different types of callouts. The first was concerning a problem in the non-ventilated area of the domestic hot water system, the second was a propane leak to the cooker hob and the third was a booked service to our oil boiler. Of course, they have all the necessary accreditation to carry out this diverse work and it was accomplished without delay in a really very pleasant manner. They were careful and tidy and obviously very knowledgeable about the work they were doing. All in all, I am very pleased to have found them and already trust them knowing they can actually do what they say they can. Excellent company.

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

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.

I had originally booked in Southgate and Culham Ltd in for October but my boiler burst at the end of July ? I rang them immediately and they were extremely helpful, I was able to pay for the work through finance, and they started the work the following Monday! They fitted a new boiler, a new oil tank and all of the pipework. The woman who answered the phone spent half an hour talking through the issue with me and was so helpful, they were exceptionally clean and really helped me out. Huge thanks and highly recommended!

Second to None for Good Efficient Service in Replacing Oil Boiler

We recently had our old oil boiler serviced and several expensive spare parts replaced. Shortly afterward, unfortunately, decided to gurgle for a few days and then completely gave up the ghost. Understandably due to the current health situation, it seemed to be impossible to get anyone to come out to see what the problem was until we contacted Southgate and Culham. On hearing that we had no heating or hot water, and the emersion heater did not work either, despite it being a very busy period Nikki arranged for an engineer to call within a few days. As repairing the boiler was no longer an option we decided to have it totally replaced. All the team pulled out all the stops to get us a quote and fit the new boiler within a week from initially diagnosing the problem. The engineers arrived four days after the call out, Kevin and Wayne, who were both very friendly and professional and adhered to the current recommendations regarding COVID 19. The boiler was fitted and the degree of efficiency and competency was second to none. We would not hesitate to recommend this firm and their phone number is definitely now on our speed dial.

We had a site visit book but our boiler finally packed in so Southgate & Culham (Nikki) helped out by giving us a quote over the phone confirmed that our choice of boiler (Worcester Bosch ) were market leaders. Kevin then arrived 0n time to confirm all the details ,the quote came out cheaper than we though which in the light of our position (no hot water etc) was very refreshing. 3 days later Wayne the fitter arrived again on time and proceeded to fit our new boiler with no hassle or stress at any time just great re-assurance. The whole experience from start to finish has been 100% positive, and we feel very pleased to have been dealt with in such a totally professional way by a totally professional company.

I received very prompt attention when first contacting Southgate & Culham, including a visit to ascertain the problem with my boiler. Once a new boiler was decided it was installed within the week. The work was carried out with professional efficiency within 4 hours. I am extremely pleased with the result. Many thanks to the team at Southgate and Culham. I would highly recommend this trader. The "would you recommend this trader?" section below doesn't seem to be working as I can't indicate yes!

Had way too many quotes from various suppliers (my mistake!) offering different solutions for replacement of our leaking boiler. Didn't think an external boiler would be within our budget and was told by one supplier it couldn't be done! Southgate and Culham explained everything in plain English and came across as honest and trustworthy people so they got the job. Great work, a tidy installation and we've never been warmer, plus the hot water tank finally fills up properly and has not run out once, so we are well pleased. Definitely recommend and they will be getting the service work too.

Southgate & Culham were selected to install our gas central heating based on good reviews and a competitive price. Right from our first phone conversation with Nikki in the office, to our site inspection and finally, installation, we have received prompt and courteous service. Kevin and Wayne carried out the installation, they answered our questions and queries and were polite. They arrived on time, on the day arranged and made sure our water supply was only off for the minimal time. After the installation we had a small query, and our email was promptly responded to. We would definitely recommend Southgate and Culham they are competent and efficient.
