    Reliable and efficient engineer

    Posted 19 December 2025

    Dave is a thorough & knowledgeable engineer; he recently replaced all our radiators ensuring they each were correct sizes for individual rooms. He completely flushed the system out to increase the efficiency & also serviced the boiler. Dave replaced & upgraded our downstairs cloakroom also; giving advice regarding new bathroom furniture.

    pierced gas pipe fix

    Posted 10 December 2025

    Dave booked and completed the work within 24 hrs of the issue taking place. He was incredibly informative about the work he was about to complete and gave a quote upfront upon seeing the work that needed to be done. He was friendly and left the kitchen clean and tidy when he was finished. We are happy with his work, and relieved he was able to fix it the day after it happening so we have access to heating and hot water again!

    Excellent worker

    Posted 19 October 2025

    Dalco Gas with David was a very good experience by a knowledgeable and capable plumber who worked hard with little or no breaks installing boiler, new pipes and valves and ventilation flue to better standard than existed before. Gas Safe registered and a hard worker. Highly recommend.

    Emergency toilet leak

    Posted 16 October 2025

    Pipe broke in toilet & couldn't stop the water flow. David was the 3rd call I made to find a plummer & 1st to answer the phone ! (it was a a Sunday morning). Came out within an hour & was able to turn off the water (I couldn't get the stopcock to move). Managed to make a temporary repair so I could use the loo & agreed to return in the week to complete a more permanent fix. Fixed leak in boiler too. Good as his word, came back a few days later with new fittings for my loo & now back in full working order! Very happy with the service provided & recommend.
