What the EPC data shows for CM17 (Harlow)
We’ve aggregated the current Energy Performance Certificate band for 8,390 properties in CM17 (Harlow), drawn live from the GOV.UK EPC Register. The median home in our sample sits at band C, with 39% falling into band C and 29% in band B. Around 31% of homes are at band D or below — the cohort with the most realistic retrofit upside.
| Band | Properties | Share | Retrofit context |
|---|---|---|---|
| Band A | 84 | 1.0% | Already exceptional; heat pump replaces fossil heat directly |
| Band B | 2,393 | 28.5% | Strong fabric; heat-pump-ready after minor checks |
| Band C | 3,265 | 38.9% | Typical retrofit candidate; small upgrades likely |
| Band D | 2,175 | 25.9% | Insulation prerequisites likely; well-suited post-upgrade |
| Band E | 394 | 4.7% | Insulation recommendations typically required for BUS |
| Band F | 62 | 0.7% | Significant fabric improvements before heat pump fit |
| Band G | 17 | 0.2% | Fabric-first retrofit before any heat-pump consideration |
The typical CM17 (Harlow) home
What the EPC data shows beyond the headline rating — useful context for sizing a heat-pump install.
- Floor area: median 78 m² (25th–75th percentile: 63–102 m²). Heat-pump sizing scales roughly with floor area — expect a 5–8 kW unit at the median.
- Current heating cost: median £456/yr (£287– £714 typical range). The number an installer’s running-cost saving projection sits against.
- Mains gas connection: 88% of properties. Most homes are replacing a working gas boiler — the payback case depends heavily on tariff choice + smart scheduling.
- Property type mix: Detached 25%, End-Terrace 18%, Mid-Terrace 25%, Semi-Detached 27%.
- 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 CM17 (Harlow)?
Yes. CM17 (Harlow) 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 CM17 (Harlow) 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 CM17 (Harlow)
Pre-grant install costs in CM17 (Harlow) 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 CM17 (Harlow)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 CM17 (Harlow)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 CM17 (Harlow)
Based on the median CM17 (Harlow) home in our EPC sample — a semi-detached house around 78 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.
| Line | New gas boiler | Air-source heat pump |
|---|---|---|
| Finance | £70/mo | £54/mo |
| Energy | £94/mo | £105/mo |
| Service / cover | £20/mo | Not required |
| Total per month | £184/mo | £159/mo |
At today’s standard tariffs, that’s about £25/mo cheaper with the heat pump — roughly £300 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.
