10.5% of homes are rated F or G — above the national average of 2.9%.
When it comes to energy performance, YO21 in North Yorkshire manages an average of 61 out of 100, placing it below the national average. Compared to the national average of 67, that puts YO21 below the norm for England and Wales. The most common rating band is D, with 12.5% of homes rated A or B and 57.1% in the C or D bands. Meanwhile, 10.5% 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. Flats make up a notable 25% of homes here. Around 66% of properties are owner-occupied , while 23% are privately rented . Gas central heating is the main fuel source for 67% of homes, which is typical for urban areas across England.

Frequently asked questions
What is the average EPC rating in YO21?
Homes in YO21 have an average EPC rating of D, scoring 61 out of 100 for energy efficiency. That figure comes from 6,087 certificates issued across the district.
That is below the national average of 67, which means there is real scope to improve energy efficiency here. A D rating typically means higher-than-necessary heating bills, especially in older properties without adequate insulation.
What percentage of homes in YO21 are rated F or G?
10.5% of homes in YO21 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means YO21 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.
