Environmental Performance Certificates
ODUG developing business case
Data request description:
Energy Performance Certificates (EPCs) provide information on energy efficiency, energy costs and carbon emissions for individual properties. All homes bought, sold or rented in England and Wales require an EPC. Most types of non-residential property also require an EPC. The EPC data additionally includes useful general property details such as property type, total floor area, floor height and number of rooms. EPC data is held in a central database, the EPC Register.
The data is available but only to specific categories of re-user and at the discretion of the data provider. There are also financial charges for the data. Earlier this year, following a consultation, the DCLG began to make individual Energy Performance Certificates accessible to the public via a website, and to license the bulk data to certain categories of "authorised recipient" based on criteria set by DCLG. There is a description of the availability of the data and the current charging regime on the DCLG website. Now that DCLG has conceded that there is no privacy barrier to public release of EPCs for individual addresses, it should be viable to open the bulk data more widely as well.
Potential uses of this data include: -- analysis and research to promote and improve energy efficiency in buildings, including the development of commercial apps and services, -- enhancement of comparables used in real estate appraisal, and -- sociodemographic analysis in support of policy development and action by local government and community groups.
1. Broad availability of EPC data would influence calculations and decisions in the property market, particularly in the private rental sector. Homebuyers and tenants would find it easier to compare properties and estimate the total costs of occupancy, and owners would be incentivised to improve the energy efficiency of their properties. 2. Social landlords and other property investors would be able to judge the energy efficiency of their portfolios relative to housing and commercial stock in the same local areas, and prioritise improvements. 3. DCLG maintains that the current charging regime, for authorised recipients of the bulk EPC data, is required only to "cover the cost of collating and providing the data." If that is the case, there is clearly scope for a more cost-efficient process. Releasing the data in bulk would enable developers and users to "cut" the data themselves or present the data through APIs. This would eliminate the cost of preparing extracts of the data at source.
