Tony arrived on time as promised. Our central heating was fully inspected and safety checked in order to resolve a pressure loss issue. Every procedure was carefully explained and the fault identified and rectified in an expansion vessel very quickly. This service was professional clean and efficient. I shall use GOS Heating for my annual system service in future. Thankyou.

Excellent service. New boiler fitted and will continue to use them for servicing. Highly recommended.

The engineer attending my house on time this morning he serviced my boiler give it a little bit extra love and care which I knew because I hadn't had a gasman he retired but I was impressed with ny service i live in a flat and I need not to worry about my safety and my neighbours thank you very much see you next service

Great service, very professional. Would definitely recommend.

GOS Heating replaced a very old back boiler with a modern Vaillant combi system. The customer is my mother who is almost 91 years old. A couple of issues arose, one relating to the shower with the change from gravity system to pressurised. The other was a non installation related but coincidental electrical promlem. The GOS engineers were patient and tolerant with my elderly mother and saw the job through to a satisfactory conclusion. I have no hesitation in recommending GOS as a reputable and trustworthy company.

Arrived on time, polite and carried out the service without any issues

Engineer Chris Baron came to service our boiler & to have a look at our radiators as one wasn’t warming up as much as the others. He said we wouldn’t need to flush the system but just balance it so that all radiators were getting equally as warm. Once he had done this you could notice a difference straight away. Very pleasant & informative, explaining everything he had done. Great job.

Prompt & reliable servicing every year

Excellent job. Thanks Tony !

Called GOS after the previous plumber couldn't fix a problem with the heating. The lady on the phone was really helpful and found an engineer just finishing up and sent him straight over. Chris was excellent, quickly diagnosing and explaining the problem. He was spot on and had it fixed within minutes. Really nice guy, and refreshing to meet someone with a solid understanding of heating systems and excellent customer service. Will definitely be calling GOS first next time.

Been using GOS for years for boiler servicing. Always reliable, can't fault them.

Nat was very helpful, pleasant and nothing was too much trouble. Thanks!

I have used GOS on two major household improvement projects which I couldn't compromise on. They are simply the best. Their knowledge is deep and their planning and execution is first class. All this while being accessible and friendly and not too corporate. That takes skllied leadership, authenticity and a genuine care about the finished product or service, which emanates from call operators to the installers and supervisors. I commend GOS without hesitation.

Excellent service

Excellent service have used them for years now, never let me down, quick, prompt and very knowledgable would give 6 stars if I could

Very helpful and friendly engineer. Found the problem straight away and fixed it. Very happy with the visit. Heating working again now.

Have used GOS to service my central heating system since they installed it in June 2012.Happy with their service and reliability.
