Energy Performance Certificates (EPCs) are required by law whenever a property is built and needed if someone wishes to sell or let their property.
The purpose of the EPC is to give you an indication of how much it will cost you to heat and light the property, and how much CO2 the property emits.
With an energy efficiency rating from A (most efficient) to G (least efficient), an EPC is valid for 10 years. Each EPC contains both information about a property’s energy use and typical energy costs and recommendations about how to reduce energy use and save money.
The better the rating on the EPC certificate, the lower the cost of running the property.
AFD’s range of address lookup and address cleansing solutions can now return EPC data for the address
being validated and appended to addresses
during a batch data cleanse process.
Using the form below, enter your postcode or start typing an address to see results. Select an address and you will see a complete list of results returned.
As not all properties will have an EPC, please use HD3 2AF as an example.
This enhanced dataset helps the property sector with accurate and upto date data, safety and energy efficiency in many ways:
Bill Powell, Software Development Manager at bpha:
“AFD’s solutions enabled us to cleanse our property database and add property level grids to the data. We also appended UPRN data to match Energy Performance Certificates (EPC) to each property, quickly identifying how well insulated they are.
EPC data allowed us to instantly identify a list of our poorest performing properties, so we could then plan what performance upgrades were needed to keep our tenants safe and warm. This vital job would be impossible to get right without having an authoritative dataset of accurate property details that we could match with the EPC data.”
Available EPC data that can be returned with an address lookup or appended during database cleansing:
CURRENT ENERGY RATING
Current energy rating converted into a linear ‘A to G’ rating (where A is the most energy efficient and G is the least energy efficient)
POTENTIAL ENERGY RATING
