The grant is only part of the decision
The Boiler Upgrade Scheme can reduce the upfront cost of eligible heat pump installations, but the overall return depends on insulation, radiator sizing, current heating fuel, electricity tariff and seasonal performance.
Installer assessment still matters
An installer should assess heat loss, hot water needs and whether emitters need upgrading. A calculator can model the economics, but it cannot replace a property survey.
How CalcAI helps
Use the heat pump calculator to model grant support, running costs and payback. If the result is worth exploring, request no-obligation quotes from MCS-certified installers.
