DN1 is around the national average for energy efficiency.
3.3% of homes are rated F or G — above the national average of 2.9%.
For the 4,454 homes assessed in DN1, the average energy score comes in at 64 out of 100, placing it around the national average. The national average is 67, which means DN1 performs roughly in line with the rest of the country. The most common rating band is C, with 3.2% of homes rated A or B and 75.1% 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 C rating suggests reasonably efficient homes, though there is still room for improvement on heating and insulation.
Flats make up the bulk of the housing in this district. Flats make up a notable 48% of homes here. Around 28% of properties are owner-occupied , while 48% are privately rented and 23% are social housing. That high proportion of rental homes matters — landlords in DN1 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 75% 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 64 to 78 — a 14-point jump that would lift the typical rating to C.

Frequently asked questions
What is the average EPC rating in DN1?
Homes in DN1 have an average EPC rating of D, scoring 64 out of 100 for energy efficiency. That figure comes from 4,454 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 DN1 are rated F or G?
3.3% of homes in DN1 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means DN1 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.
