About the DCA
The Data Co-operation Agreement is issued by GeoPlace® LLP to all district, county and Unitary councils in England and Wales. It provides a legally binding agreement between the parties to support the creation and maintenance of GeoPlace databases (particularly related to address and street information for England and Wales and address information for Scotland through separate agreements).
The Agreement underpins a recognition by government of the substantial social and economic benefits that core reference geography brings and forms part of the framework put in place by Government to enable access by the whole of the public sector to definitive spatial information through the Public Sector Mapping Agreement (PSMA). The Agreement also recognises the role of councils in the creation and source of particular spatial information.
With an Effective Date of 1st April 2012, the DCA replaces similar arrangements between all councils and the Local Government Information House (LGIH - a subsidiary of the LGA) which were in place from 2005 (the Mapping Services Agreement (MSA)) and expired on the 31st March 2012.
Welcome to the DCA
You are part of the most successful shared service arrangement there has been in Great Britain. The AddressBase range of products and the National Street Gazetteer are used across the public and private sector and are informed by the hard work you do as the Custodian for your authority in partnership with GeoPlace.
This document summarises the relationship between Data Cooperation Agreement (DCA) contacts and GeoPlace, including the DCA contractual arrangement and governance structure. It also provides information on how address and street data is used within councils; further information about GeoPlace, including key contact details, and where to find key documents and resources to help you in your day-to-day role.
The document also provides information and evidence of the benefits of well managed address and street data to councils. From tax revenues to route optimisation in waste management, the savings stem from transforming the way services are delivered, enabling channel shift and reducing duplication of effort.
The address and street data you create and maintain is also being widely used by central government:
drives the location services on your smart phone
helps emergency responders share information more effectively get to call outs
enables utilities to connect services to a new home
is used by the Office for National Statistics to collect census data
helps packages be delivered to your house
is used by HMRC to detect fraudulent activity across tax systems
helps identify properties suitable for sustainable energy schemes
is part of the Individual Electoral Registration programme
helps ensure the UK has secure, clean, affordable energy supplies
is used by Tell Us Once to ease the burden of reporting a bereavement
used for risk assessment and underwriting by insurance companies
enables the Health and Safety Executive (HSE) staff to rapidly identify and prioritise high-risk businesses for inspection along with their locations
