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.

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

Central heating problem was identified and resolved very efficiently. What was annoying about the problem was that the part had been replaced less than 18 months previously. Poor quality part as original one lasted more than 15 years.

Truly epic company that just go that little bit more than anyone else which makes them stand out from the rest

This firm attended our house promptly at the agreed time, and carried out a most intricate plumbing investigation and repair. They were not only informative throughout the process, but completed the work in a timely manner and left the workplace spotlessly clean. I would recommend them 100%.

Excellent service, the engineer talked me through the whole process, explaining the issue and what he was doing. Work done in 1 hour, and left clean and tidy.

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

Chris and the team at GOS have looked after our boiler since fitting it 12 years ago. Very friendly and professional service. Have recommended this company to many of our friends.

Many thanks Tony for the excellent service of our gas appliances today.

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

Great service, very professional. Would definitely recommend.

Thoroughly impressed by the experience of dealing with GOS who ultimately installed a new boiler and replaced radiator valves and thermostats. From Nicki, in the office; Tony, who did the survey; and Dave & Richard, who did the installation, the whole process was undertaken in a professional, timely & friendly manner. What also impressed was when, even after being paid, I alerted GOS to a slight leak from one of the radiator valves they arranged for an engineer to visit the next day to remedy the matter. Would I use GOS again? A definite YES!

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.

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.

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

The workmen were polite and helpful. They arrived on time and finished on schedule leaving the place spotless. The follow up was useful too.

Absolutely fantastic service. Thanks Sam.

Our landlord started using gos a few years ago and they have been great from the start. Today we had a new boiler installed by Sam and Richard it was a big job. The guys were absolutely great friendly and worked really hard to get the job done. Can't recommend this company enough brilliant from start to finish. Thank you
