What MCS certification means

MCS (the Microgeneration Certification Scheme) is the UK quality mark for installers of small-scale renewable technology, including heat pumps¹. Certification is technology-specific: an installer certified for air source heat pumps isn't automatically certified for ground or water source, so always check the specific scope against the technologies listed above rather than assuming certification covers everything. MCS certification is also the gateway requirement for the £7,500 Boiler Upgrade Scheme grant, without it, an installer cannot register for BUS at all, regardless of how experienced they are.

Verifying this listing before you sign anything

What a proper quote from this installer should include

Whichever installer you choose, a proper quote follows the same structure regardless of company size. It should start with a room-by-room heat-loss survey, typically 2 to 4 hours on-site, not a walk-around estimate. The written quote that follows should show the gross price and, where BUS applies, the £7,500 deduction as a separate line, not folded into a single "all-in" figure. It should specify the exact heat pump model and kW output, the designed flow temperature, an estimated SCOP for your specific property, and which radiators (if any) need upgrading. If a quote is missing any of these, ask for it in writing before comparing prices, a cheaper number that's missing a survey or a SCOP estimate isn't actually comparable to one that includes them.

Get at least 3 quotes before signing anything. A single quote is hard to judge in isolation, three lets you spot which one is missing something or pricing unusually high or low.

If Asset Plumbing & Heating Ltd isn't able to take on your project, or you'd simply like a wider comparison, browse the rest of the London listing or search a neighbouring area.
