Daryll quickly messaged back from my post on Saturday morning, booked to come Monday morning at 8:30, turned up on the dot, very reliable. Took a look and luckily was a quick fix that morning, job took no longer than half hour with a full fix. Heating is working perfectly with a brand new system. Amazing job and hugely reliable, explained the problem thoroughly, would highly recommend and book myself again in the future for any issuesVerified reviewerJob location: SA1Response from Griffiths Gas Ltd

10 Great experience
Posted 08 January
Great work. He came over to service the boiler and cap a fireplace. It turned out the fireplace was already capped, but he made sure that everything was done correctly and removed a lot of the old pipes and bits. He also made sure that all the radiators were working correctly, after I mentioned that a couple of them were not heating properly. Really recommended!Verified reviewerJob location: SA1 - MMartin A
10 Restoring heat to a cold radiator
Posted 24 December 2025
Darryl provided a first-class service from start to finish. Responsive, reliable, efficient and friendly, he identified and resolved a long-standing issue with our living room radiator that was giving no heat (despite previous plumbers’ attempts and advice) and is now working brilliantly. Really impressed and grateful.Verified reviewerJob location: SA3Response from Griffiths Gas Ltd

10 Boiler service and safety test
Posted 08 October 2025
Job location: SA2Thanks, Darryl. Very professional service! Highly recommend! I needed to service a boiler. One of the gas engineers said that the flue was too close to the window and gave a huge quote for flue extension. I asked Darryl for a quote but he actually climbed on a ladder outside to the flue and measured the distance with the ruler! The distance was within limits approved by regulations. So Darryl saved me a lot of money and headache. Both times appeared on time. Was very helpful answering the questions. Also recommended main gas cutoff tap replacement, and called the authorized service for it.
