Free personalised heat pump estimate
A smarter estimate, built around your home
We use details about your property, local climate and heating system to build a tailored estimate for heat loss, running costs, suitable heat pumps and available grant support.
Step 1
Find your property
Start typing your address. We’ll use the property and postcode to build the first estimate.
Gathering data
Analysing your home digitally
We found your property
Does this look right?
One quick grant check
Your EPC suggests . Does the property have a mains gas connection or gas meter point?
Estimated design heat loss
Useful for instant system selection. Final MCS sizing follows the room-by-room design.
No EPC found
No problem — we can still build an estimate
Answer a few quick questions. We’ll use building-age defaults, your postcode climate and the details below.
Climate & property model
Why this estimate is specific to your home
We combine the property with local design conditions rather than using one generic UK winter temperature.
Fabric / degree-day model
—Annualised from design heat loss, local design temperature and degree days.
EPC energy cross-check
—Uses EPC energy information where the certificate exposes a usable annual value.
Working annual space-heating demand
—Used for space-heating running-cost estimates and confidence checking.
System optimisation
Efficiency versus disruption
Lower flow temperatures can improve seasonal efficiency but may require more radiator upgrades. The final room-by-room design confirms the actual emitter changes.
Heat pump position
How far will it be from the existing boiler or plant area?
This adds a sensible pipe-route allowance without pretending the online estimate can inspect the route.
Savings, running costs & smart tariffs
How could your heating costs change?
Compare the estimated cost of your existing fuel with the selected heat pump, then see how a heat-pump tariff and sensible scheduling could reduce it further.
Supplier availability and rates vary by region and change over time. The configured review date is shown alongside each tariff.
Your estimated heat pump
Choose your preferred system
We match the smallest available unit that meets the estimated load at the local design temperature, then let you compare the systems that suit your home.
