(Carbon Savings Community Obligation (CSCO Eligibility System)

We’ve just successfully delivered a new publicly available online Postcode Checker Tool to the Office of Gas and Electricity Markets (Ofgem).

Ofgem is the government regulator for the electricity and downstream natural gas markets in Great Britain.  Based in London, and employing a team of approximately 800 staff, Ofgem protect the interests of existing and future electricity and gas consumers in Great Britain.

Ofgem appointed thinkWhere in October 2014 to develop, maintain and host an online Postcode Checker tool to aid installations of energy efficiency measures under the Community Obligation (CSCO) of the Energy Companies Obligation (ECO).

The new tool makes use of publicly available data sources from data suppliers such as the Office of National Statistics (ONS), Scottish Government and the Department of Energy and Climate Change (DECC).  Working closely together on the development of the new tool, Ofgem and thinkWhere started the project mid October 2014, with release of the completed live product a few weeks later at the end of November.  Complex data management structures and algorithms sit behind the scenes of the data model.  However, the online tool has been designed to make the user experience as simple, clear and concise as possible.  Available 24/7 on desktop and mobile devices, the design of the Postcode Checker tool is responsive and supports all major, widely used browsers.

Consumers, energy suppliers, the ECO supply chain and Ofgem themselves can now easily confirm whether postcodes in GB are eligible under CSCO, to identify CSCO eligible areas and to validate CSCO specific information:

  • The Map Search allows the identification of CSCO eligible areas based on specific criteria via an online Mapping portal.  This uses Open Data available through the OpenSource “Location Centre” platform developed by thinkWhere.  The site includes black and white or full colour background maps and shows Low Income Areas, Low Income Adjoining Areas, Rural Areas and Deprived Rural Areas.

  • The Validation tool is designed for use by the ECO administrator, energy suppliers and those within the ECO supply chain wishing to validate ECO specific data (this function is not designed for use by consumers).  Click here to validate data

The site will be hosted by thinkWhere for a 3 year period with regular updates to the information applied as required.
