PO31 is around the national average for energy efficiency.
3.6% of homes are rated F or G — above the national average of 2.9%.
When it comes to energy performance, PO31 in Isle of Wight manages an average of 65 out of 100, placing it around the national average. Compared to the national average of 67, that puts PO31 around the norm for England and Wales. The most common rating band is D, with 8.1% of homes rated A or B and 74.2% in the C or D bands. Meanwhile, 3.6% 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 77% of properties are owner-occupied . Gas central heating is the main fuel source for 86% 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 65 to 80 — a 15-point jump that would lift the typical rating to C. That is a substantial gain, suggesting many homes are missing basic efficiency measures. If you live in PO31 and want to reduce your energy bills, start with our guide to loft insulation — it is one of the most cost-effective upgrades you can make.

Frequently asked questions
What is the average EPC rating in PO31?
Homes in PO31 have an average EPC rating of D, scoring 65 out of 100 for energy efficiency. That figure comes from 5,507 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 PO31 are rated F or G?
3.6% of homes in PO31 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means PO31 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.
