SS0 is around the national average for energy efficiency.
3.3% of homes are rated F or G — above the national average of 2.9%.
Based on 14,668 Energy Performance Certificates, SS0 in Southend-on-Sea has an average EPC score of 62 out of 100, placing it below the national average. To put this in context, the national average sits at 67. The most common rating band is D, with 4.9% of homes rated A or B and 72.7% in the C or D bands. Meanwhile, 3.3% 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.
Most of the housing stock here consists of flats. Flats alone account for 53% of all certificated properties — a distinctly urban profile. Around 56% of properties are owner-occupied , while 38% are privately rented . That high proportion of rental homes matters — landlords in SS0 must comply with the Minimum Energy Efficiency Standards (MEES), which currently require at least an EPC E rating. Properties rated F or G cannot legally be let. Gas central heating is the main fuel source for 88% 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 62 to 77 — 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.

Frequently asked questions
What is the average EPC rating in SS0?
Homes in SS0 have an average EPC rating of D, scoring 62 out of 100 for energy efficiency. That figure comes from 14,668 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 SS0 are rated F or G?
3.3% of homes in SS0 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means SS0 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.
