What's in the quote

Unit supply, labour, pipework, hot-water cylinder (if needed), controls, commissioning and MCS certification. The BUS grant is claimed by the installer and deducted.

Why quotes differ

Different assumptions on radiator upgrades, cylinder, and heat-loss sizing. A proper heat-loss survey beats a rule-of-thumb size — and avoids an oversized, costly unit.

Paying fairly

Use only MCS-registered installers (required for the grant). Compare like-for-like scopes, not headline prices. Our company directory lists verified providers.

FAQs

Why are heat pump quotes so different?
They assume different upgrades (radiators, cylinder) and sizing methods; compare scope, not just price.
Who claims the grant?
Your MCS installer claims the Boiler Upgrade Scheme and takes it off the quote.
