What you need to do with spending returns

You must send copies of election spending returns and declarations to the Commission as soon as reasonably practicable after the return or declaration is received. Please also provide copies of the relevant invoices and receipts.

Please also supply the following information to enable us to carry out our compliance duties:

  • statement of parties and other persons nominated, notice of agents, and declaration of result for each election
  • confirmation of who has not delivered a return or declaration

Our preferred method of receipt is secure document transfer, which will make the process of delivering these returns easier for you. The Commission can provide access to a secure document transfer system on request. Please contact us at [email protected] to arrange this.

If for any reason you prefer to email the returns and declarations, please email scanned PDF copies to [email protected]. It will be of significant help to us in processing emailed returns and declarations, and prevent queries from us to you, if you:

  • scan each candidate’s spending return or declaration, with the relevant invoices and receipts, separately
  • send each return by separate email, as very large attachments will be rejected by our server
  • identify the constituency and the candidate name in the subject line of the email
  • do not password protect emails or provide passwords or secure websites – a normal email is fine

If neither of the above options are viable, you can forward paper copies of the returns to the following address:
