Heat pumps in Derby: 2026 grant + cost guide

What the EPC data shows for Derby

We’ve aggregated the current Energy Performance Certificate band for 73,967 properties in Derby, drawn live from the GOV.UK EPC Register. The median home in our sample sits at band D, with 40% falling into band D and 34% in band C. Around 55% of homes are at band D or below — the cohort with the most realistic retrofit upside.

The typical Derby home

What the EPC data shows beyond the headline rating — useful context for sizing a heat-pump install.

• Floor area: median 73 m² (25th–75th percentile: 59–90 m²). Heat-pump sizing scales roughly with floor area — expect a 5–8 kW unit at the median.
• Current heating cost: median £792/yr (£498– £1,125 typical range). The number an installer’s running-cost saving projection sits against.
• Mains gas connection: 90% of properties. Most homes are replacing a working gas boiler — the payback case depends heavily on tariff choice + smart scheduling.
• Property type mix: Detached 21%, End-Terrace 12%, Mid-Terrace 28%, Semi-Detached 36%.
• Dominant age band: England and Wales: 1900-1929 (18% of homes). Sets the fabric-first work expected before commissioning.

Does the Boiler Upgrade Scheme apply in Derby?

Yes. Derby is in England, where the Boiler Upgrade Scheme (BUS) pays £7,500 toward an air-source heat pump install. The grant is administered by Ofgem and deducted by the installer at the point of invoice — you never see the cash. To qualify, the property must be owner-occupied or privately rented, have a valid EPC issued in the last 10 years, and have no outstanding loft-or-cavity insulation recommendation on the EPC (unless an exemption is documented). In our sample of Derby EPCs the median rating is band D, which means most homes need to clear at least one insulation recommendation before the installer can claim the grant.

Typical install cost in Derby

Pre-grant install costs in Derby typically run £8,000 to £14,000 for a 5–10 kW air-source unit, in line with UK averages — labour rates in East Midlands sit close to the national mean. After the £7,500 BUS deduction most Derbyhomeowners pay £1,500 to £6,500 out of pocket. The figure within that range that applies to your property depends on three things: heat-loss sizing (set by floor area, fabric and air-tightness), radiator upgrades (most pre-2000s homes need at least one or two changed), and hot-water cylinder provision. An MCS-certified engineer issues the binding quote after a heat-loss calculation per BS EN 12831.

What this means for your home

Whether a heat pump is a good fit for your specific home in Derbydepends on three factors the EPC alone can’t answer: roof + outdoor space for the external unit, radiator sizing throughout the heating circuit, and your current heating fuel + tariff. Propertoasty’s free pre-survey check combines your address, an EPC pull, the Google Solar API’s roof data, and a floorplan vision analysis to produce an installer-ready report — typically takes about five minutes.
