The typical BN45 (Brighton) home

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

  • Floor area: median 103 (25th–75th percentile: 75165 m²). Heat-pump sizing scales roughly with floor area — expect a 5–8 kW unit at the median.
  • Current heating cost: median £944/yr 568– £1,607 typical range). The number an installer’s running-cost saving projection sits against.
  • Mains gas connection: 17% of properties. Predominantly off-grid — heat-pump running-cost case is unambiguous vs oil and LPG.
  • Property type mix: Detached 45%, End-Terrace 8%, Mid-Terrace 7%, Semi-Detached 39%.
  • Dominant age band: England and Wales: before 1900 (24% of homes). Sets the fabric-first work expected before commissioning.

Does the Boiler Upgrade Scheme apply in BN45 (Brighton)?

Yes. BN45 (Brighton) 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 BN45 (Brighton) 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 BN45 (Brighton)

Pre-grant install costs in BN45 (Brighton) typically run £8,000 to £14,000 for a 5–10 kW air-source unit, in line with UK averages — labour rates in E12000008 sit close to the national mean. After the £7,500 BUS deduction most BN45 (Brighton)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 BN45 (Brighton)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.
