Energy Performance Certificates
Complete UK EPC register with 20M+ certificates. Energy ratings, efficiency scores, running costs, CO2 emissions, and building component analysis for every assessed property.
Complete EPC Register
20M+ certificates from official government registers. Domestic, non-domestic, and Display Energy Certificates. Full historical record with multiple assessments per property.
Dual Rating System
Both letter grades (A-G) and numerical SAP scores (1-100) for precise filtering. Current ratings show today's efficiency; potential ratings reveal improvement opportunity.
Running Cost Analysis
Annual heating, hot water, and lighting costs in pounds. Compare current vs. potential to quantify savings. Essential for rental yield calculations.
Overview
Access the most comprehensive Energy Performance Certificate database in the UK, covering over 20 million domestic and non-domestic assessments across England, Wales, and Scotland. Each certificate contains detailed energy efficiency analysis including current and potential ratings (A-G), numerical efficiency scores (1-100), annual running costs, CO2 emissions, and component-level assessments for walls, roof, floor, windows, heating, and hot water systems.
Our EPC data integrates directly with the Property Index, enabling energy-aware property analysis for valuations, portfolio screening, retrofit planning, and regulatory compliance. With MEES regulations requiring minimum E ratings for rental properties and net-zero targets driving market premiums for efficient homes, EPC data has become essential infrastructure for property intelligence.

Use Cases
MEES Compliance Screening
Screen rental portfolios for Minimum Energy Efficiency Standard compliance. Properties rated F or G are unlettable without exemption. Identify non-compliant assets before they become stranded.
LendersRetrofit Investment Analysis
Compare current vs. potential ratings to quantify improvement opportunity. Running cost savings justify retrofit investment. Target D-rated properties upgradeable to B/C for maximum value creation.
DevelopersGreen Mortgage Underwriting
Factor energy efficiency into mortgage risk models. A/B rated properties retain value better. Lower running costs improve affordability calculations. ESG-compliant lending requires EPC data.
LendersCarbon Footprint Reporting
Aggregate CO2 emissions across portfolios for ESG disclosure. Track decarbonisation progress over time. Identify highest-emission assets for prioritised intervention.
InvestorsProperty Valuation Enhancement
Energy efficiency increasingly material to property values. Premium properties command higher prices. Running costs affect rental yields. EPC provides standardised quality signal.
ValuersTenant Cost Transparency
Disclose estimated running costs to prospective tenants. Required at marketing under Consumer Rights regulations. Differentiate efficient properties in competitive markets.
