Election candidate target databases

As part of your subscription to our Advocacy tools, we also provide candidate databases for selected data sets which you can use with Email-to-Target pages.

Before using a candidate database…

We strongly recommend that you use a custom envelope for sending to candidate targets, otherwise delivery is likely to be affected. Please check this article on how to do this, or talk to support.

Which candidate databases are provided?

We provide:

  • Westminster MP candidates

  • Devolved nations candidates (Scotland, Wales and Northern Ireland)

  • Police Commissioner candidates

  • London Assembly candidates 

  • Mayoral candidates – note that these should be used as custom contacts rather than a postcode-matched database. Please contact support who can provide you with a candidate list nearer these elections

When are these released?

We would expect to provide a working database roughly 3 months before an election, with coverage increasing every week after making it available. We will provide an ongoing report to show you how many candidates are currently on the list and then you can decide when to launch your campaign.

While this takes place, we will clear the actual target databases (we will mark this as DO NOT USE) since it would otherwise contain out of date data.

Once the election is over and candidates elected, we update the actual databases for you to use with the new targets and close the candidate database. We would have the new database ready for you a couple of days after the results are published on official websites. For a rough guide after the election ends you should expect the database to be ready:

  • UK – within a week for national elections, or over a month after councillor elections. 

  • USA – 2-3 months

  • Canada – a number of weeks, usually over a month.

  • Australia – a number of weeks, usually over a month. We will let you know once the databases have been updated after the recent Australian elections. 

What databases will you provide for elections in 2024?

UK local elections in 2024

  • UK / Special : Constituency lookup 2024 – A new database has been created that includes changes to constituency boundaries. This can be used to label supporters via data mapping. If you do not have this database and would like to use it, please contact your account manager

  • Councillor databases – these have been updated with new targets after the recent local elections. Council leads is yet to be updated, but is planned for July 2024

  • UK / English : Police Commissioners – this is now updated and ready to be used as of May 2024. Note that two PCC districts have been abolished – South Yorkshire and North Yorkshire

  • UK / English : London Assembly – this is updated after the recent elections

UK General Election in 2024


We released a candidate database on 5th July 2024 which should no longer be used.

We are preparing an updated Westminster MP database which is planned to be released on Thursday 11th July 2024.

What about boundary changes?

We will take account of the new boundary changes in the new Westminster MP database. You can use this to data map these to your supporter record, or alternatively use the “UK / Special : Constituency lookup 2024” dataset to do this.

What about candidate databases for councillor elections?

We do not provide a candidate database for councillor elections. There is a lot of work required to maintain candidate databases. Data changes frequently, and often use personal email addresses. This data is hard to collect, and hard to verify.

The councillor databases contain many thousands of contacts, and with candidates as well this would multiply the list by many times. It would be a massive undertaking to provide this accurately.

In addition, ward boundaries change during an election and Ordnance Survey do not release these new boundaries until after the election. It is therefore not possible for us to properly match a postcode to a ward and to select the correct candidates.
