    Trusted for Our LPG Boiler for Years

    Posted 27 January

    We’ve been using this plumbing company for over ten years to service our LPG boiler, and we honestly couldn’t ask for better service. They’ve always been responsive, reliable, and genuinely helpful whenever we’ve needed them. With our old property especially, they were consistently thorough and professional, taking the time to explain things clearly and making sure everything was working safely and efficiently. It’s rare to find a company you can trust year after year, but they’ve never let us down. Highly recommended for anyone looking for dependable, long-term boiler and plumbing support.

    High quality work but poor communication

    Posted 16 December 2025

    GK plumbing completed a full bathroom renovation I cannot fault the quality of the work completed, Ian and Lucas did a high spec job with great attention to detail. However do not be taken in by Russ, all he is is a sales manager, not a project manager. Communication when he is trying to win your job will be faultless, rapid responses, answering all your questions But once he has your deposit don't expect to hear from him. Comms will fall of a cliff, I only received updates after multiple chases. The team was changed with no warning, he attended the start of the job 10 days after it started

    Response from GK Plumbing & Heating

    Dear Bethany, Thank you for your review, having seen your new bathroom you chose some lovely sanitaryware and the finished result is beautiful. I can only apologise our communication wasn't as you would have liked and it is something we will highlight to everyone involved, so we can make the necessary improvements. Kind regards, Kelly

    Main Bathroom Refurb

    Posted 17 November 2025

    We couldn’t be happier with our experience! Russ, the project manager, was fantastic from start to finish. Roger, Ian, and Lucas didn’t just show incredible attention to detail, they also covered such a wide range of skills, from plumbing and plastering to carpentry, tiling and finishing touches. They kept everything tidy and didn’t stop until we were completely happy with the final result. The fact that Russ personally came at the end to sign everything off, down to the tiniest details, really made a difference. An absolute pleasure all around!

    Installation carried out without any problems, mess or inconvenience.

    Posted 14 November 2025

    GK Plumbing installed our boiler system 3 years ago and subsequently carry out an annual service. The original installation was carried out without any problems, mess or inconvenience to ourselves and on a timely basis. The annual services are similarly problem free and we have complete confidence in the skill and customer care all members of the business provide.
