The median home in our sample sits at band C, with 31% falling into band D and 26% in band C. Around 46% of homes are at band D or below — the cohort with the most realistic retrofit upside.
| Band | Properties | Share | Retrofit context |

| Band D | 1,424 | 30.8% | Insulation prerequisites likely; well-suited post-upgrade |
| Band E | 547 | 11.8% | Insulation recommendations typically required for BUS |

The typical CB10 (Saffron Walden) 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: 69–130 m²). Heat-pump sizing scales roughly with floor area — expect a 5–8 kW unit at the median.
- Current heating cost: median £608/yr (£360– £1,031 typical range). The number an installer’s running-cost saving projection sits against.
- Mains gas connection: 70% of properties. Mixed grid: heat-pump payback runs much shorter for the off-grid minority (oil / LPG).
- Property type mix: Detached 36%, End-Terrace 12%, Mid-Terrace 15%, Semi-Detached 35%.
- Dominant age band: England and Wales: before 1900 (14% of homes). Sets the fabric-first work expected before commissioning.
Does the Boiler Upgrade Scheme apply in CB10 (Saffron Walden)?
Yes. CB10 (Saffron Walden) 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 CB10 (Saffron Walden) 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 CB10 (Saffron Walden)
Pre-grant install costs in CB10 (Saffron Walden) 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 CB10 (Saffron Walden)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 CB10 (Saffron Walden)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 CB10 (Saffron Walden)
Based on the median CB10 (Saffron Walden) home in our EPC sample — a detached house around 90 m² — here’s what the two options look like on a like-for-like monthly total. Boiler numbers assume a £4,150 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.
| Line | New gas boiler | Air-source heat pump |
|---|---|---|
| Finance | £88/mo | £54/mo |
| Energy | £107/mo | £122/mo |
| Service / cover | £20/mo | Not required |
| Total per month | £215/mo | £176/mo |
At today’s standard tariffs, that’s about £39/mo cheaper with the heat pump — roughly £468 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.
