Existing Air Source Heat Pump systems have a terrible reputation in the UK as being expensive to install and expensive to run. To help you understand some of the reasons why they deserve that reputation and they are so expensive, I offer a direct comparison between a “MCS” ASHP and an “Affordable” ASHP.

I am fitting an affordable air source heat pump in my own home in October 2025 having obtained a prices for a MCS air source fitted and designed by a MCS fitter (September 2025.)
My home is a large 5 bedroom detached home with:-
5.5 KW Hr Roof Mounted Solar PV System
2 KW Hr Roof Mounted Indirect Solar Thermal System (own design)
Excellent retrofit insulation.
Thermaskirt heated skirting.
Novel twin 22mm open loop hot water distribution.
25 KW Hr Hot Water Thermal Heat Store
12.5 KW Hr Tesla Electric Power Bank
Octopus considered my home unsuitable for a MCS air source heat pump however MCS registered R A Brown Heating Services gave me a price fully compliant price. I compare and contrast the design and cost differences in the following YouTube Video.
