WD24 Watford
Watford Rating D Score: 65 / 100

WD24 is around the national average for energy efficiency.

For the 7,142 homes assessed in WD24, the average energy score comes in at 65 out of 100, placing it around the national average. The national average is 67, which means WD24 performs roughly in line with the rest of the country. The most common rating band is D, with 9.2% of homes rated A or B and 75.7% in the C or D bands. Meanwhile, 1.6% 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. Flats make up a notable 34% of homes here. Around 56% of properties are owner-occupied , while 28% are privately rented and 16% are social housing. Gas central heating is the main fuel source for 83% 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 65 to 80 — 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 WD24?

Homes in WD24 have an average EPC rating of D, scoring 65 out of 100 for energy efficiency. That figure comes from 7,142 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 WD24 are rated F or G?

1.6% of homes in WD24 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.

This is actually better than the national picture, suggesting the housing stock in WD24 is in relatively good shape — though any home rated F or G would still benefit enormously from basic upgrades. Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
