Surrey rankings
Surrey towns with strong green credentials
For buyers who weight energy efficiency highly, the proportion of properties in an area already rated EPC Band C or above is a useful starting signal — it reflects both the age of the stock and the extent of retrofit investment in the area. This ranking lists Surrey outcodes by that share, with gigabit broadband coverage as a secondary column (high connectivity supports working from home and reduces commuting).
EPC certificates are issued at point of sale or rental — not all properties have a current certificate on the register. The sample size per outcode affects the reliability of the percentage; outcodes with fewer than 10 lodged certificates are excluded.
Green Belt, AONB and SSSI designation, solar panel penetration and active travel infrastructure are relevant to green-credentials buyers but are not yet available as per-outcode live data in this system — see the methodology section.

EPC percentages are computed across all lodged certificates for the outcode. Outcodes with fewer than 10 certificates are excluded.
How we ranked this
The ranking uses two criteria applied in order:
- EPC Band C or above share (primary sort) — the proportion of EPC-registered properties in the outcode whose most recent certificate shows Band A, B or C. Computed as a percentage across all lodged certificates for the outcode prefix. Higher share ranks first. Outcodes with fewer than 10 lodged certificates are excluded. Data source: EPC Register (Ministry of Housing, Communities and Local Government), Open Government Licence v3.0.
- Gigabit broadband coverage (tiebreaker) — proportion of premises in the outcode where a gigabit-capable connection is available. Supports working from home and reduces commuting demand. Data source: Ofcom Connected Nations, Open Government Licence v3.0.
Not yet wired — additional green signals: Green Belt and AONB designation, solar panel penetration from MCS data, proportion of EVs in the area, and active travel infrastructure are all relevant to green-credentials buyers but are not available as per-outcode aggregated live data in this system. This ranking therefore uses EPC as the primary proxy.
EPC Band C or above is a useful but imperfect proxy. Newer-built properties and recently retrofitted homes are more likely to be rated C+. An outcode dominated by older housing stock that has been retrofitted may score higher than a newer development whose certificates have not yet been lodged.
