    Emergency boiler service

    Posted 01 February

    Posted a job early Sat and was attended to by lunchtime. The heating was fixed but repair required new parts which were fitted the next day. Great experience would definitely recommend DMK and use again

    Boiler Service

    The engineer contacted me 30 mins before he arrived stating what time he will be at my property. When he arrived he completed the job within 30 minutes. Great service would definitely recommend them.

    The engineers were on time, with good communication skills. They explained how the boiler worked on completion and tidied up after themselves.

    They came quickly, sorted the boiler service I needed and left, no complaints good job done. Even took their shoes off at the door if that matters to some people. Would recommend
