Average rating: 5.0 out of 5
Review by MARK ELIADES
on 15th October 2025
"Have no hesitation in awarding these guys 5*. Phoned them around 15:30pm and the job was finished by 18:00pm. Very reasonable price and no mention of an "Emergency Call Out Fee", even though the Water Tank Lawrence was working on was a b*tch to get to...oh, and let's not mention the wasp's nest!!"

Review by Gerry Bloomfield
on 5th August 2025
"Very happy. You were so quick at taking out the old boiler and installing the new Vailent, plus changing a radiator full of sludge. We were grateful that you cleared away all the redundant stuff and then commissioned and tested everything. Top marks!"

"Brilliant service. Laurence went out of his way to source a difficult to find replacement thermostatic shower valve and had it fixed within 24 hours of the first call. Great communication all the way through. Thoroughly recommended."
