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.

Heat pump install that looks like part of the architecture

Sharp Renewables installed our Vaillant aroTHERM Plus last year. The plinth they specified, the louvred cladding, the planting around it - the unit looks intended, not bolted on. The system itself runs beautifully through winter.

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.

Solar and battery, installed properly

GivEnergy 9.5 kWh battery paired with a 6 kW solar system, all run on neat trunking, app working perfectly. The cabling is tidier than the electrics that were already in the loft. Professional throughout.
