Will replaced our 22 year old boiler, which was definitely on it's last legs, with a brand new Bosch Worcester. We also took the opportunity to replace 6 radiators, 3 with towel rails, upgrade the gas main pipe and had thermostatic valves fitted throughout the house. We valued Will’s advice on which radiators to replace and their size and his flexibility throughout the job. We found Will to be very professional, explaining what he was doing and keeping us informed of this arrival times. We have not experienced any problems whatsoever since the installation and would not hesitate at all in recommending him or using him again in the future.
Brilliant service from Will and Josh while installing a new boiler and radiators in our house. Both were extremely friendly and professional and really went the extra mile to ensure we were happy with the service they provided. I wouldn't hesitate to use them again in the future or recommend them to friends and family.
An awesome job in a very short lead time. We had a whole new boiler sourced and fitted bang on time. I really trusted you both in our house as I couldn't be there all the time. I returned after day 1 to know you were on track and the work area so clean and tidy for our family. Thank you so much Will and Josh. The work is neat and tidy and Josh even spotted one of our radiators was missing a control and popped one on for us :O) I received complete instructions on how to use the thermostat and Josh had preset everything so we were ready to go. After being in a cold house with no hot water over a full weekend I felt so blessed to have them on my team on Monday morning to get it sorted! Now I know exactly why both my neighbours recommended you :O)
Will replaced my 17 year old boiler, and updated the out of date gas supply expertly, efficiently and speedily. I was delighted with the new boiler. From the first enquiry, the estimate and the conclusion of the installation the service was all first class with Will and Josh explaining every step of the way. I recommend R.W. Thomas Plumbing and Heating without any hesitation.
