Supply and fit boiler
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.Verified reviewerJob location: SE2510 Central Heating

Check the boiler is safe with no leaks
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!Verified reviewerJob location: SE2010 Central Heating
