    Reliable & Knowledgeable Heating Engineer

    Posted 11 May

    Gary replaced my boiler about 5 years ago & did an excellent job.... clean, tidy & professional. Since then he has provided the annual service & always responds immediately to my WhatsApp requests. Recently the heating would occasionally fail to fire up . I messaged Gary who replied with the probable cause & fitted me in the following day. His diagnosis was spot on..... system fixed, tested & the overdue annual boiler service all done efficiently & without fuss in less than 2 hours. I can't recommend Gary enough.

    The best service !

    As usual. A very efficient visit by Gary. Complete heating are always prompt , efficient and competitively priced. We planned an annual boiler service but had to ask for 2 annoying system leaks to be repaired. Gary managed to fix both in one visit. A perfect service

    Great Service And Honest Advice

    Posted 18 January

    I have been a customer of Complete Heating and Gas Ltd for a few years now, and have always been happy with the standard of work carried out and the high level of service received. Gary is always courteous and polite and provides good honest advice and guidance, and I therefore have no hesitation in recommending him and CH&GL. He sourced and fitted a replacement for one of the valves in our shower mixer recently, to cure a leak that had developed before Christmas. As usual, the work was completed quickly and efficiently, and at a very reasonable price. I'm very happy to endorse CH&GL.

    The Gas Safety Certificate of my Flat happens to need renewal during Festive Season. Gary always communicates effectively with the residents of the property to conduct the job. He is also very punctual, friendly, easy going and also professional at the same time

    Gary fixed our boiler - he diagnosed the problem, sourced the part and fitted it all at a very reasonable cost. In the past he has also fixed our underfloor heating and leaks - he is extremely reliable and efficient.
