Completeness and accuracy reports

Great Britain and Northern Ireland have two different electoral registration systems and studies have therefore been conducted separately.

Pilot Evaluation Reports

By law we have to evaluate pilot schemes that test changes to how electoral registration works in Great Britain.


Public opinion research

Winter tracker research

Once a year, we conduct a UK-wide survey to find out the public's views on electoral issues such as the voting and registration process, party finance and electoral fraud.

See our Winter Tracker page for our latest headline findings

The most recent surveys are available below. The 2012, 2013 and 2014 research also included a black and minority ethnic (BME) groups boost element.


Post-election surveys

We also conduct  public opinion surveys following elections

See our post-election survey page for our latest headline findings
