EPC Price Check

Does a C-or-better EPC sell for more in EX15 3 (Mid Devon)?

No premium here: C+ homes sold for slightly less. In postcode sector EX15 3 (Mid Devon), comparing like with like — same floor area, property type, build period and year of sale — homes rated C or better sold for 6.1% less (95% range −9.8% to −2.2%). The raw gap is different: C+ homes sold for 0% less per square metre than D–G homes (median £2,970 vs £2,976, 1,029 sales 2015–2026), mostly because they are different homes.

From the raw gap to like-for-like

The homes are not alike: C+ homes here have a median floor area of 111 m² against 90 m² for D–G; the most common build period is 2012 onwards for C+ and before 1900 for D–G; 73% of C+ and 74% 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 EX15 3 (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)47 (1,015 meters)
Median gas use per meter (median of postcodes)8,576 kWh
Gas-heated homes with an EPC787
Energy implied by their certificates (median)12,165 kWh
Metered gas as a share of the certificate figure (median of 45 postcodes)59% (middle half 47%–70%)

Certificates by band imply: B 6,750 kWh (182 homes) · C 10,979 kWh (304 homes) · D 18,053 kWh (237 homes) · E 30,393 kWh (53 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.

1,029 of 1,184 house and flat sales in the sector since 2015 (87%) were matched to a certificate.
