  • Gas boiler service on Ideal Combi c35

    10Verified Review

    The engineer arrived within the allotted appointment time, he was very polite and courteous. Not sure whether I can mention his name in this review but his initials are AH, hopefully this review will be passed onto him. He carried out the service in a timely manner and left the area clean and tidy. This is the first time I've used John Williams and I would definitely use them again and recommend them to family and friends. Very impressed impressed with their engineer he's a real credit to John Williams. Thank you

  • Replacement of syphon and fill valve in close coupled toilet

    9.5Verified Review

    Professional and reliable. They reply to emails promptly and offered advice, explained what was likely needed and why. Sufficient office staff to respond to questions. The quote for the parts and the time to do the job was accurate. Plumber phoned before arriving stating he'd finished the previous job earlier than anticipated, so was it okay to come to us, earlier than arranged. Having had to remove the toilet and cistern from the wall, replaced all, resealed and left the room clean and tidy.

    I have used this company for at least 12 years. Once fault found and Part ordered was back with in 3days. Excellent service as always especially as I was without an oven and having only 2 electric rings.
