Immergas air source heat pumps, installed properly
Pictured: a recent Sharp Renewables install in St Albans. The Immergas unit is sited against the brickwork on a considered base, pipework fully insulated, acoustics handled so it disappears into the side of the house. Quiet, efficient, and fitted to last.

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.
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
Fox ESS 11.5 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.
Bathroom refit, finished to a high standard
A complete bathroom strip-out and rebuild. The plumbing under the floor is a piece of work in itself, and the finish on the visible elements - Hansgrohe valves, tiling, vanity unit - is exactly what we wanted.
ASHP retrofit, competitive and excellent
Tom and his team installed a 5Kw ASHP heating system. It was a retrofit for a flat previously heated by electric heaters. I had several quotes for the job and Sharpheating were very competitive and did an excellent job. From accepting the quote and getting the work done was only a few weeks and Tom was very responsive to my emails and queries. Would recommend
