Excellent service

Just had boiler serviced arrived on time excellent service, excellent knowledge would highly recommend and will definitely be using again.

In Autumn 2023 I moved into a property with a quirky heating system that needed urgent replacement as the temperatures were falling. I contacted GOS and they ripped out the old heaters and replaced everything with a top-of-the-range Gas Combi and rads. This has worked efficiently. I have just had the first twelve monthly service; all good. As well as high quality products I liked the fact that the personnel are pleasant and punctual. Recommended.

Always use GOS for Gas boiler servicing and have always been very satisfied with the service (especially by Chris B). So when we had problems with a thermostatic bar shower, i had no hesitation in calling GOS.. Chris came to assess the issue, explained what options we had and once we decided to replace, he fitted a new shower bar. Very happy. Thanks Chris!

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.

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!

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

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

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

Efficient, on time, very clean & tidy up after themselves, great finish to the kitchen and all work done managed by a great project manager in Kerry. Made the process smooth and as little disruption as possible, given the nature of a having a new kitchen. I would recommend to anyone.

Worked very well and professionally always on time all work completed on time to a very high standard and removed all packaging and left everware clean and tidy would recommend highly

Excellent service all round when dealing with low pressure issues on my boiler. Diagnosed the issue quickly and helped the external gas transporter understand what they had to do to resolve the issue. Went above and beyond for us as a customer in doing so. Special mention to Chris our gas engineer and Julie for organising the works. Can’t speak highly enough of them.

Sam and Liam arrived on time, provided protection for all flooring and units, did an amazing very neat job and left the place immaculate. Both guys had an amazing attitude and left us feeling very comfortable- no question was ignored and happy to work with us as some item estimate covered weren’t need. Kept us informed throughout and brought in support when needed with electrics (as wiring wasn’t as expected/should have been).. Looking to do some further work next year so will be definitely asking GOS to quote and for these guys to be given the work. Sam is very precise in his work and you’d never guess Liam had been with company a month given professionalism he showed and way he answered question. First class service- what more can I say.

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

Very happy with the service everything explain to us in detail.. would highly recommend.thank you.

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.

Gos heating have just installed a new boiler and central heating at my grandmother's house. They have done an outstanding job. Great fitters, hard working and courteous, left everything spotless. Nothing was too much trouble. I cannot recommend them highly enough. Thank you guys!
