Does a C-or-better EPC sell for more in RH14 0 (Chichester)?
Too few comparable sales here for a reliable like-for-like figure. In postcode sector RH14 0 (Chichester), comparing like with like — same floor area, property type, build period and year of sale — there are too few comparable sales in each group for a reliable figure; for district RH14 as a whole the like-for-like difference is −3.9% (95% range −6.0% to −1.8%). The raw gap is bigger: C+ homes sold for 9% more per square metre than D–G homes (median £4,700 vs £4,319, 825 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 133 m² against 138 m² for D–G; the most common build period is 2012 onwards for C+ and 1950–1966 for D–G; 92% of C+ and 85% of D–G sales are detached or semi-detached houses.
This sector has fewer than 150 matched sales, fewer than 30 in one group, or an estimate too imprecise or implausibly large to trust, so the like-for-like comparison is not shown; the district figure is above.

Can the local grid take heat pumps in RH14 0?
SSEN does not publish spare capacity for street substations, so this is the answer for the wider district fed by the Plaistow primary substation (33/11 kV), not for your street. It has no winter demand headroom for 2027 in SSEN's lowest scenario (−2.8 MVA): new heat pumps here depend on reinforcement.
| Primary substation | Share of the sector's gas homes | Headroom 2027 | Gas homes in its area | Room for heat pumps | Headroom 2030 / 2035 (Holistic Transition) |
|---|---|---|---|---|---|
| Plaistow | 92% | −2.8 MVA | 112 | none | 11.2 / 9.4 MVA |
| Billingshurst (upstream constraint) | 4% | 6.1 MVA | 2,566 | ≈ 3,590 (100%) | 6.0 / 4.1 MVA |
| Five Oaks | 3% | 3.6 MVA | 1,171 | ≈ 2,090 (100%) | 2.7 / −0.2 MVA |
Across the sector, about 10 of 97 gas-heated homes (8%) could switch within the primary substations' 2027 headroom.
Caveat: a primary substation feeds a whole town or several villages. Your street's own substation can be full while the primary has room, and the other way round. Headroom: SSEN Network Scenario Headroom Report 2026, winter demand headroom after contracted connections (MVA ≈ MW). Homes: postcodes whose centre lies inside SSEN's published supply area (19 October 2026). A full primary substation means reinforcement (usually a delay), not a refusal. All areas and the method.
825 of 982 house and flat sales in the sector since 2015 (84%) were matched to a certificate.
How this is calculated
- Every standard sale (HM Land Registry Price Paid, category A) since January 2015 is matched to the latest energy certificate of the same address (postcode + house number or name + flat) lodged from 10 years before to 3 months after the sale; sales with no certificate or an ambiguous match are left out. Across England and Wales 92% of sales match.
- Price per m² uses the certificate's total floor area (15–1,000 m²).
- Like-for-like premium: regression of the log of price on “C or better”, log floor area, property type, the certificate's build period and the year of sale. The 95% range shows how precise the estimate is; when it includes zero, the data cannot tell the premium apart from none.
Caveats
- The band is the one on the certificate before the sale; certificates are a median 0.8 years old at the sale, but a quarter are over 4 years old and some homes were improved since.
- Condition, garden, parking, views and the exact position within the sector are not known; a premium could hide in them, or they could hide one.
- Individual sales and addresses are not shown.
