What boiler installation customers say
Quietly excellent from start to finish
Tom and his team installed a Viessmann Vitodens 200-W in our kitchen extension. They treated the boiler position as part of the design conversation, ran the pipework where it would never be seen, and left the kitchen cleaner than they found it. Considered work from start to finish.
Attention to detail is rare
I have used a lot of trades over the years. The standard of finish here is unusual. Sharp Heating refitted our boiler, re-ran the gas line through a chased wall, and made good with a quality we would expect from a proper finisher, not a heating engineer.
Did exactly what they said they would do
Quoted a fixed price for a Worcester 8000 Style, turned up when they said they would, finished when they said they would, charged exactly what they said they would. No hidden anything. The team is genuinely professional.
Brilliant boiler install
Tom and the team swapped our Worcester Bosch the same week we called. Clean, tidy, and the kitchen was spotless when they left. Fixed price, no surprises.
Boiler swap done in a day
Quick combi-to-combi swap with no surprises. The engineers were tidy, polite, and explained the new controls properly.
Polite, tidy, professional
Every visit they covered floors, wore overshoes, swept up before they left. Small things, but they show care.
