Consumer feedback

Generated from the text of this trader's consumer reviews

Gasworks Plumbing & Heating Ltd comes highly recommended by customers who have relied on them for a decade for boiler servicing, repairs and plumbing emergencies. Reviewers describe a consistently professional, friendly approach—engineers like Michael, Carl and Lloyd are singled out for arriving on time, working cleanly, and explaining checks in clear, reassuring detail. During a very cold spell, one customer praised how they were “an excellent find” after a boiler expiry, with fast action that minimised disruption to heating and hot water.

What Customers Say

  • Reliability and timekeeping: Customers repeatedly note they “always turn up on time” and even “arrived early”, including engineers who reached homes quickly when boilers failed.
  • Thorough explanations and peace of mind: Carl’s gas safety checks are praised as “incredibly thorough,” while Michael consistently “took his time to explain” appliances and service steps clearly.
  • Quality workmanship and cleanliness: Many mention first-class standards, courteous fitters, and tidy finishes—“cleared up afterwards” and leaving rooms “lift tidy and clean.”
  • Responsive fixes and thoughtful follow-through: From sourcing parts swiftly (including getting a flue fan fitted “first thing the NEXT morning”) to making sure customers know what to watch for if issues return, service is described as “10/10.”
  • 0 missed appointments in the past 6 months

    "I have used Gasworks for several years, receiving consistently good service. An excellent find at time when the heating boiler expired during a very cold winter spell. Would warmly recommend them."

    "Gas Safety Checks - From my first call to the company right through to the completion of the work, I had a really great experience. Carl arrived on time and made sure everything was clearly explained, so I knew exactly what had been checked. He was incredibly thorough and professional throughout. I’ve had bad experiences with tradespeople in the past, but this has completely restored my faith. I wouldn’t hesitate to recommend this company to others!"

    "I have had to call out this company three times and the engineer Michael came each time. My boiler is more than 15 years old, so doesn't qualify for insurance cover. The first time he came it took him half an hour to identify the problem, went out and purchased the part and returned and after fixing it, gave me instructions on what to look out for if the problem re-ocurred. Absolutley first rate service, friendly, polite, and knowledgeable. The second time was a boiler service, and on the most recent occasion the boiler stopped working, basically the gas won't fire up. Michael came and identified the problem which required a replacement part. Considering the age of the boiler, he was able to source the part, collected it from the supplier a few miles away, and returned the next day to fit it and get the boiler back up and running with a warm home in time for Christmas. That was very considerate of him to go the extra and I can highly recommend this company unreservedly. 10/10."
