What the EPC data shows for Slough
We’ve aggregated the current Energy Performance Certificate band for 5,000 properties in Slough, drawn live from the GOV.UK EPC Register. The median home in our sample sits at band C, with 64% falling into band C and 23% in band D. Around 26% of homes are at band D or below — the cohort with the most realistic retrofit upside.
| Band | Properties | Share | Retrofit context |
|---|---|---|---|
| Band A | 18 | 0.4% | Already exceptional; heat pump replaces fossil heat directly |
| Band B | 483 | 9.7% | Strong fabric; heat-pump-ready after minor checks |
| Band C | 3,191 | 63.8% | Typical retrofit candidate; small upgrades likely |
| Band D | 1,145 | 22.9% | Insulation prerequisites likely; well-suited post-upgrade |
| Band E | 143 | 2.9% | Insulation recommendations typically required for BUS |
| Band F | 15 | 0.3% | Significant fabric improvements before heat pump fit |
| Band G | 5 | 0.1% | Fabric-first retrofit before any heat-pump consideration |
Does the Boiler Upgrade Scheme apply in Slough?
Yes. Slough 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 Slough 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 Slough
Pre-grant install costs in Slough typically run £8,000 to £14,000 for a 5–10 kW air-source unit, in line with UK averages — labour rates in South East sit close to the national mean. After the £7,500 BUS deduction most Sloughhomeowners 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 Sloughdepends 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.
