AL6 Stevenage
Welwyn Hatfield Rating D Score: 67 / 100

AL6 is around the national average for energy efficiency.

3.1% of homes are rated F or G — above the national average of 2.9%.

The 3,475 EPC certificates on record for AL6 paint a clear picture — the area averages 67 out of 100, placing it around the national average. The national average is 67, which means AL6 performs roughly in line with the rest of the country. The most common rating band is D, with 15.3% of homes rated A or B and 69.9% in the C or D bands. Meanwhile, 3.1% 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.

Houses make up the bulk of the housing in this district. Around 77% of properties are owner-occupied . Gas central heating is the main fuel source for 89% 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 67 to 80 — a 13-point jump that would lift the typical rating to C.

Frequently asked questions

What is the average EPC rating in AL6?

Homes in AL6 have an average EPC rating of D, scoring 67 out of 100 for energy efficiency. That figure comes from 3,475 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 AL6 are rated F or G?

3.1% of homes in AL6 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.

That means AL6 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.
