Amazing service. I had an old Ideal boiler and hot water tank removed and a new Atag combi fitted in my garage. The work was first class,polite and friendly. Very clean and made good after the job was completed. Thoroughly recommend Gareth. Dan and Josh worked very hard and were very clean. The whole job was completed within in a week. I had the Atag One controller fitted and can control the boiler from my IPad. My gas bill has been slashed having this boiler fitted(Economiser 30) Thank you Gareth,Dan,Josh and Dave.

I found Gareth Williams Heating on this site and booked them to do a service on my combi boiler. The communication was great and the service from start to finish was just as good. I was so impressed I have asked for the company to service my boiler every year from here on in.

Kind caring courteous and very professional
So close to Christmas my old boiler gave up. Gareth came promptly and looked at all the possible options to give me the best deal. Very impressive. Dan was exceptional in his efforts to get the work done in order to accommodate my needs. A very kind and thoughtful young man along with being very good at his job. All paperwork emailed so I can safely file away. Very efficient service. I would highly recommend Gareth and Dan to anyone as you don't just get very skilled workmanship but very kind and caring gentlemen.

Really great service and work. They came to supply and fit a new radiator and bathroom tap, fitted the radiator without any issues and made a lovely job, really tidy and no mess. Found that they didn't have the correct tool to fit the tap I supplied, asked if they could go and finish a couple of other jobs scheduled for the day and pick up the tool needed and return to finish the job. returned ad they had said and finally finished the job at 6.00pm, really happy with the outcome and the level of service provided.

Gareth and Dan removed our existing boiler, installed its replacement (including associated work) and magnacleansed the system - all within two days. This was quicker than I expected, due to their hard work, knowledge and efficiency. They were prompt, courteous, friendly and did an excellent job. I am very pleased and cannot recommend them too highly.
