Client's Feedback

  • Customer in Greater London
    Keiran was available quickly and solved the problems with our hot water system, diagnosing the hot water/HIU problem and getting it working. Easy to communicate with and professional.

    Our combi boiler stopped working, on a very cold day, along with the drains blocking up. Nightmare! I phoned Keiren at 9am, and he arrived at 1pm. He fixed the boiler very efficiently, and arranged for a plumber to come and fix the drain too. The bill was very reasonable. I'd definitely recommend him, and we are having the boiler serviced by him next week (if we had done that before, it wouldn't have stopped working...).

    I called at 8am today having taken delivery of a new dual fuel cooker which i thought would be installed upon delivery. By 6pm this evening it was all up and running. Smooth and efficient service. Would highly recommend them. Thank you.

    I first used All Heat Systems about five years ago to replace the boiler in a property I rent out. Reliable and excellent service throughout the job. I have been using the firm since then for all boiler repairs, maintenance and regular safety checks. Fast, reliable and honest, and fairly priced.
