LL65 Ynys Môn
Isle of Anglesey Rating D Score: 61 / 100

LL65 is below average for energy efficiency — most homes here have room to improve.

10% of homes are rated F or G — above the national average of 2.9%.

For the 8,431 homes assessed in LL65, the average energy score comes in at 61 out of 100, placing it below the national average. The national average is 67, which means LL65 performs below most areas. The most common rating band is D, with 11.8% of homes rated A or B and 60.4% in the C or D bands. Meanwhile, 10% 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.

Houses make up the bulk of the housing in this district. Around 57% of properties are owner-occupied and 25% are social housing. Gas central heating is the main fuel source for 74% 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 61 to 83 — a 22-point jump that would lift the typical rating to B. That is a substantial gain, suggesting many homes are missing basic efficiency measures.

Frequently asked questions

What is the average EPC rating in LL65?

Homes in LL65 have an average EPC rating of D, scoring 61 out of 100 for energy efficiency. That figure comes from 8,431 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 LL65 are rated F or G?

10% of homes in LL65 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.

That means LL65 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.
