PO20 is around the national average for energy efficiency.
3.5% of homes are rated F or G — above the national average of 2.9%.
When it comes to energy performance, PO20 in Chichester manages an average of 68 out of 100, placing it around the national average. Compared to the national average of 67, that puts PO20 around the norm for England and Wales. The most common rating band is D, with 22.8% of homes rated A or B and 62.0% in the C or D bands. Meanwhile, 3.5% of homes sit in the F or G bands — the least efficient categories. In practical terms, a rating of D means many homes here lose more heat than average — potentially adding £200-400 per year to energy bills compared to a C-rated home.
The area is characterised by houses. Around 76% of properties are owner-occupied . Gas central heating is the main fuel source for 84% of homes, which is typical for urban areas across England.
There is genuine room for improvement here. If every recommended upgrade were carried out, the average score could climb from 68 to 82 — a 14-point jump that would lift the typical rating to B.

Frequently asked questions
What is the average EPC rating in PO20?
Homes in PO20 have an average EPC rating of D, scoring 68 out of 100 for energy efficiency. That figure comes from 13,359 certificates issued across the district.
This is broadly in line with the national average of 67 — neither particularly efficient nor particularly wasteful. A D rating typically means higher-than-necessary heating bills, especially in older properties without adequate insulation.
What percentage of homes in PO20 are rated F or G?
3.5% of homes in PO20 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means PO20 has a higher-than-average proportion of poorly insulated homes. On the positive side, many of these properties may qualify for free improvements through government schemes like ECO4 or the Great British Insulation Scheme. Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
