Will from R.W. Thomas Plumbing and Heating Ltd came and serviced our Boiler. Although the boiler was working fine just needing a service Will checked thoroughly not only the boiler but the gas and water pressure to ensure it would continue to work properly. He was happy to explain what he was doing and left the site clean and tidy. Prices are reasonable and I will use him again next year.

Excellent service from Will from R.W. Thomas Plumbing and Heating Ltd for arranging our new Worcester Bosch boiler to be fitted at such short notice, and thank you to Josh for installing the boiler and pipework. Extremely friendly and professional workmanship and really went the extra mile when a few niggles materialized. We were extremely happy with the service they provided. I wouldn't hesitate to use them again in the future and would recommend them to anybody who requires any heating, plumbing, gas or boiler work.

Mr Thomas originally installed our new oil boiler and associated pipe work in 2014 and we have used him ever since to carry out the annual inspection and service. We couldn’t wish for a more friendly and professional person to perform this task and are very pleased with the result .
