A first-visit triage — capture the property, fabric, hot water, emitters, outdoor unit siting and electrics, and get a clear read on suitability and grant eligibility before you commit to a full design.
⚠️ This is an indicative triage, not the MCS design or a grant guarantee. Sizing still needs a full room-by-room heat loss (BS EN 12831); eligibility and grant figures must be confirmed against current GOV.UK / Ofgem rules.
1 Property
2 Current heating & fuel
3 Insulation & fabric
4 Hot water & cylinder space
5 Emitters & pipework
Tip: confirm each room with the Radiator Check once you have heat loss figures.
6 Outdoor unit siting
7 Electrical supply
8 EPC & grant
9 Customer notes
Indicative only. This triage supports an MCS-certified installation but does not replace it. Final sizing requires a full BS EN 12831 heat loss; outdoor unit noise & siting must meet MCS 020 / permitted development; and Boiler Upgrade Scheme eligibility and grant amounts must be confirmed on GOV.UK / Ofgem before quoting.
