LL68 Ynys Môn
Isle of Anglesey Rating D Score: 57 / 100

LL68 is below average for energy efficiency — most homes here have room to improve.

15.1% of homes are rated F or G — above the national average of 2.9%.

Across 2,061 assessed properties, LL68 achieves an average EPC score of 57 out of 100, placing it below the national average. For reference, the England and Wales average is 67 — so LL68 is below that benchmark. The most common rating band is D, with 4.9% of homes rated A or B and 57.7% in the C or D bands. Meanwhile, 15.1% 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.

Walk through LL68 and you will mostly see houses. Around 66% of properties are owner-occupied and 20% are social housing. Gas central heating is the main fuel source for 59% 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 57 to 83 — a 26-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 LL68?

Homes in LL68 have an average EPC rating of D, scoring 57 out of 100 for energy efficiency. That figure comes from 2,061 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 LL68 are rated F or G?

15.1% of homes in LL68 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.

That means LL68 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.
