The Compliance Gap
The gap between the best and worst performing constituencies reveals a stark postcode lottery. Homes in the worst areas face upgrade costs, carbon emissions and energy bills far exceeding those in the best.

The gap is 41.1 percentage points. A home in Cambridge is 3.1x more likely to fail the 2030 minimum than one in Brent Central. This is not just an environmental issue: landlords in the worst-performing constituencies face the greatest compliance costs and legal risk.
Private Rental Hotspots
These constituencies combine high levels of private renting with poor EPC scores. Landlords here face the greatest compliance pressure: more properties to upgrade, and greater likelihood of enforcement action after 2030.

Methodology and Data Notes
Data sourced from the official UK Energy Performance Certificate (EPC) register via the Open Data Communities API, operated by the Ministry of Housing, Communities and Local Government. This analysis covers up to 5,000 of the most recently lodged certificates per constituency, filtered by Parliamentary constituency code.
Below-C definition: Properties rated D, E, F, or G. Under the proposed 2030 MEES regulations, private rented properties will require a minimum EPC C rating. Properties below this threshold will be unlawful to let without a valid exemption.
Solid wall: Properties where the walls description contains "solid" but not "insulated" or "filled cavity". These properties typically require external or internal wall insulation to reach EPC C.
Private rental: Properties where tenure is recorded as "Rented (private)" at time of EPC assessment. Note: many EPCs are commissioned for sales, so this figure reflects the assessed sample composition.
SAP score: Standard Assessment Procedure score (1 to 100). Higher is better. Ratings: A=92+, B=81-91, C=69-80, D=55-68, E=39-54, F=21-38, G=1-20.
Coverage: This analysis covers 25 Parliamentary constituencies selected to represent a diverse mix of urban and rural areas, regions, and socioeconomic profiles. It is not a nationally representative sample. Data current as of March 2026.
