EPC Price Check

Does a C-or-better EPC sell for more in SM7 2 (Reigate and Banstead)?

No measurable EPC premium here. In postcode sector SM7 2 (Reigate and Banstead), comparing like with like — same floor area, property type, build period and year of sale — the difference is −0.9% (95% range −3.4% to +1.6%): the EPC band itself is not reflected in sale prices here. The raw gap is bigger: C+ homes sold for 2% less per square metre than D–G homes (median £5,068 vs £5,188, 1,239 sales 2015–2026), mostly because they are different homes. Across England and Wales the like-for-like figure is +1.2%. Data: HM Land Registry Price Paid to 30 September 2026 matched to the EPC register.

From the raw gap to like-for-like

The homes are not alike: C+ homes here have a median floor area of 75 m² against 105 m² for D–G; the most common build period is 2003–2006 for C+ and 1930–1949 for D–G; 22% of C+ and 67% of D–G sales are detached or semi-detached houses.

The first row compares median prices per m²; the second compares whole prices; each later row adds one more thing that must be equal, ending with the like-for-like premium (regression of log price; build period from the certificate, 12 bands). The raw gap per m² and the whole-price gap differ because C+ and D–G homes differ in size.

Average gas use in SM7 2 (2024): meters vs certificates

A rough comparison: the certificate figure is an upper-bound estimate (primary energy including lighting, converted with one factor), so treat the share as an order of magnitude.

Postcodes with published gas data (5+ meters)125 (2,641 meters)
Median gas use per meter (median of postcodes)14,314 kWh
Gas-heated homes with an EPC1,733
Energy implied by their certificates (median)19,912 kWh
Metered gas as a share of the certificate figure (median of 121 postcodes)67% (middle half 61%–78%)

Certificates by band imply: B 7,023 kWh (49 homes) · C 11,305 kWh (635 homes) · D 22,487 kWh (731 homes) · E 32,837 kWh (280 homes) · F 49,860 kWh (37 homes). Across England and Wales, real use is much closer to the certificate for A–C homes than for D–G homes, so the saving an upgrade promises is usually smaller than the certificate suggests.

Certificate energy = primary energy per m² × floor area ÷ 1.13, for homes whose latest certificate shows mains gas heating; it also covers lighting and other uses, so it is an upper bound for gas. DESNZ gas is weather-corrected and covers all meters in the postcode, with or without a certificate.

Can the local grid take heat pumps in SM7 2?

About 1,540 of the 1,643 gas-heated homes with an energy certificate in SM7 2 (94%) could switch to a heat pump before their local substations run out of spare capacity, on UK Power Networks' figures. 6 of the 30 local substations would fill up before every gas-heated home they supply could switch.

Local (street) substations serving homes in the sector30
Already at or over capacity0 (0%)
Their combined spare capacity (demand headroom)≈ 6,770 kVA
Heat pumps that spare capacity could take, at 1.7 kW each≈ 3,980
Gas-heated homes with an EPC on these substations1,643 (95% of the sector's)
Of them, could switch within the spare capacity≈ 1,540 (94%)
…if each heat pump adds 3 kW (a cold snap)≈ 1,200 (73%)

How: each substation's spare capacity (UK Power Networks publishes utilisation in 20% bands; we take the low end of the spare-capacity band) is divided by 1.7 kW, the extra winter peak one heat pump adds once many are spread over a street; a substation can take as many heat pumps as that allows, shared among the gas-heated homes on all its postcodes whose centre lies inside the substation's published supply area. Some substations also serve neighbouring sectors, so their whole capacity is counted here and there. Spare capacity is UK Power Networks' figure as published on 15 June 2026; network operators must still be told about each heat pump, and a full substation means reinforcement (usually a delay), not a refusal. Homes without an energy certificate are not counted. All areas and the method.

1,239 of 1,321 house and flat sales in the sector since 2015 (94%) were matched to a certificate.
