    Supply and fit boiler

    Posted 15 March 2023

    John and Nick have just supplied and fitted a new boiler for me and I am immensely impressed with their work and service. They came to quote me on a Sunday afternoon, emailed me a quote the following day and I had a new boiler fitted and working by the time I cam home on the Wednesday evening. Polite, tidy and efficient! I will be using their services again.

    Check the boiler is safe with no leaks

    Posted 11 May 2022

    SGN had left me without gas due to a faulty co2 alarm!! I called few engineers and the prices where over and above what I paid 2 months ago. John had a good price and good reviews, he did the job in less than half hour and was very friendly. I would definitely recommend! Thank you John!

    The guys at JMM were knowledgeable, efficient and very friendly. They fixed my boiler and went the extra mile in explaining how other parts of the system work. Great value.
