Can I get data of current constituency boundaries to use in a geographical information system (GIS)?
Yes, current UK Parliament constituency and Scottish Parliament boundaries are available in Ordnance Survey's Boundary-Line™ product, which is available as part of the OS OpenData™ portfolio of products. OS OpenData™ products are made available by Ordnance Survey through the OS OpenData website under a licence agreement with the Department for Communities and Local Government. OS OpenData™ products are available:
- to all users;
- free of charge; and
- for free re-use, including commercial re-use.
Full details of the licence terms for OS OpenData™ are available on the OS OpenData website.
Can I get data of past constituency boundaries to use in a geographical information system (GIS)?
Can I get data of boundaries from Ordnance Survey before they come into force?
In some cases. When a major new set of boundaries is going to come into force, Ordnance Survey may produce a supplementary release of its Boundary-Line™ product in advance of the new boundaries coming into force. In these cases, the boundaries will be available as part of the next appropriate Boundary-Line™ product release to the full Ordnance Survey product specification.
For example, the Scottish Parliament boundaries for the elections in May 2011 became available when Ordnance Survey issued a supplementary release to its Boundary-Line™ product in October 2010 which included the constituencies and regions recommended in our First Periodic Review of Scottish Parliament Boundaries. An enhanced version of these Scottish Parliament boundaries, to the full Ordnance Survey product specification, became available as part of the Boundary-Line™ product release in May 2011.
Do you issue data for the boundaries that you are proposing?
When we consult on proposed boundaries during a review, we usually make shape files of those boundaries available in order to assist people to respond to our consultation. We are able to do so under the terms of our licence with Ordnance Survey. Anyone who downloads those shape files is bound by the terms of an End User licence with Ordnance Survey which we make available from the same page where the data is available.
