   We,ve had various jobs, from replacing our hot water tank and removing the tanks in the loft.,moving o a pressurised system including heating. Shower tray waste, and first fit pipe adjustment in our bathroom. We have found John Williams Heating Services to be very helpful, when dealing with the Service Admin Team, and all the installers are always polite,courteous and take pride in their work. We're so glad to have used such a good local,and reliable company.

   I have been clients with John Williams for more than 10 years. After some bad experiences with gas service providers when I moved from London to Wiltshire, I came across this family ran excellent company. John Williams was responsible for not only rectifying the careless jobs carried out by other contractors, as well as advising and installing the most efficient energy consuming ways of keeping my old Edwardian home warm through winter. My experience with the company???s expert engineers was second to none. Extremely polite and tidy, they always executed their job to perfection. I was a member of their Care Plan which made my life so much less stressful as I didn???t have to worry about finding someone to service my boiler every year. For these reasons and more, I wouldn???t hesitate to recommend John Williams to any one interested in an expert gas services providers.

   Absolutely brilliant team and so organised and professional. Ellie and Georgina were knowledgeable and a pleasure to talk to and sent their team to help with a tricky job. All done in good time, well priced and lots of communication. They are coming back to service the boiler and no doubt will be another well managed job. Highly recommend this company.

   So 8 years ago today the team at John Williams started work on our bathroom transforming into what I consider the best room in our house. I really can???t recommend their services highly enough. We also had a new combi boiler fitted the week before. And even 8 years on when we have an annual service by British Gas they always comment on the superb workmanship of the installation. We???re thinking of moving soon and John Williams Heating service will definitely be receiving a call from us soon.

   Had a new boiler installed and relocated along with some other minor jobs. The team was professional, friendly and did a great job. They also left everywhere very clean, tidy and hoovered. I'd definitely use them again and would recommend them.
