10 New combi boiler installation to replace old.
Posted 05 May
Lee was quick to reply after request was posted on Checkatrade, attended the next day to assess and quote. He was concise and provided several options which eventually met our budget. Lee and his team were able to fit us in and completed the new boiler install on the following day with no issues. Lee and Josh were very professional and credit to their cleanliness and time taken to protect the carpets prior to starting work, which is sometimes an oversight. I have no hesitation in recommending and giving them a chance to quote even if you feel you’ve obtained the best price from elsewhere.Verified reviewerJob location: LN2 - RRae W
