EPC Price Check

Does a C-or-better EPC sell for more in PR26 9 (Chorley)?

A small premium for a better EPC here. In postcode sector PR26 9 (Chorley), comparing like with like — same floor area, property type, build period and year of sale — homes rated C or better sold for 9.3% more (95% range +4.6% to +14.2%). The raw gap is different: C+ homes sold for 5% more per square metre than D–G homes (median £2,518 vs £2,395, 652 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 102 m² against 96 m² for D–G; the most common build period is 1996–2002 for C+ and before 1900 for D–G; 51% of C+ and 57% 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 PR26 9 (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)65 (1,502 meters)
Median gas use per meter (median of postcodes)11,299 kWh
Gas-heated homes with an EPC993
Energy implied by their certificates (median)18,410 kWh
Metered gas as a share of the certificate figure (median of 63 postcodes)59% (middle half 51%–66%)

Certificates by band imply: B 7,069 kWh (116 homes) · C 14,018 kWh (335 homes) · D 20,860 kWh (415 homes) · E 30,583 kWh (108 homes) · F 52,917 kWh (18 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 PR26 9?

About 900 of the 993 gas-heated homes with an energy certificate in PR26 9 (91%) could switch to a heat pump before their local substations run out of spare capacity, on SP Electricity North West's figures. 1 of the 33 local substations would fill up before every gas-heated home they supply could switch.

Local (street) substations serving homes in the sector33
Already at or over capacity0 (0%)
Their combined spare capacity (demand headroom)≈ 4,460 kVA
Heat pumps that spare capacity could take, at 1.7 kW each≈ 2,620
Gas-heated homes with an EPC on these substations993
Of them, could switch within the spare capacity≈ 900 (91%)
…if each heat pump adds 3 kW (a cold snap)≈ 780 (78%)

How: each substation's spare capacity (transformer demand headroom in kVA, from estimated maximum demand) 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 nearest SP Electricity North West substation it is (supply areas are not published). Some substations also serve neighbouring sectors, so their whole capacity is counted here and there. Spare capacity is SP Electricity North West's figure as published on 24 March 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.

652 of 713 house and flat sales in the sector since 2015 (91%) were matched to a certificate.
