The typical CB22 (Cambridge) home

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

• Floor area: median 90 m² (25th–75th percentile: 70–127 m²). Heat-pump sizing scales roughly with floor area — expect a 5–8 kW unit at the median.
• Current heating cost: median £617/yr (£394– £954 typical range). The number an installer’s running-cost saving projection sits against.
• Mains gas connection: 80% of properties. Mixed grid: heat-pump payback runs much shorter for the off-grid minority (oil / LPG).
• Property type mix: Detached 35%, End-Terrace 10%, Mid-Terrace 14%, Semi-Detached 38%.
• Dominant age band: England and Wales: 1950-1966 (18% of homes). Sets the fabric-first work expected before commissioning.

Does the Boiler Upgrade Scheme apply in CB22 (Cambridge)?

Yes. CB22 (Cambridge) 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 CB22 (Cambridge) EPCs the median rating is band C, which means most homes need to clear at least one insulation recommendation before the installer can claim the grant.

Typical install cost in CB22 (Cambridge)

Pre-grant install costs in CB22 (Cambridge) typically run £8,000 to £14,000 for a 5–10 kW air-source unit, in line with UK averages — labour rates in E12000006 sit close to the national mean. After the £7,500 BUS deduction most CB22 (Cambridge)homeowners 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 CB22 (Cambridge)depends 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.

Typical monthly heating cost in CB22 (Cambridge)

Based on the median CB22 (Cambridge) home in our EPC sample — a semi-detached house around 90 m² — here’s what the two options look like on a like-for-like monthly total. Boiler numbers assume a £3,300 installed cost on 9.9% APR / 5-year finance plus a typical £20/mo service plan. Heat-pump numbers apply the £7,500 Boiler Upgrade Scheme grant and 0% APR / 10-year finance on the net cost of £6,500.

At today’s standard tariffs, that’s about £21/mo cheaper with the heat pump — roughly £252 a year. The gap grows on a dedicated heat-pump tariff (e.g. Octopus Cosy at 15p/kWh) and as gas prices rise relative to electricity across the 10-year finance term.

How CB22 (Cambridge) compares

Compared with the England + Wales average band-D share of roughly 45%, CB22 (Cambridge)’s 32% sits below the national midpoint. Bands E and worse — typical pre-1930s homes without significant retrofit — make up 13% of the local sample, which compares to the E&W average of around 22%.
