The rules only apply in the period before certain elections. We call this the ‘regulated period’. In this period, if you spend over a threshold on regulated activity in a particular part of the UK, then you must register with us.
If your total regulated spending stays below these thresholds in each part of the UK, you do not need to register.
|Part of the UK||Registration threshold|
If your regulated spending goes over one of the thresholds, then rules apply on spending, donations and reporting, and you must register with us. It is an offence to spend more than the threshold without being registered first.
For more information on registering with us, see
In addition, please contact our advice teams who are always happy to provide you with specific advice on the need to register.
Attributing your spending to the different parts of the UK
Each of the four parts of the UK has its own separate registration threshold. This means that you will need to attribute your regulated spending to the relevant part of the UK. For example, if your campaign is run only in Scotland, then all of your spending should be attributed to Scotland.
If your campaign is run across more than one part of the UK, you should attribute the relevant proportion of the spending to each part.
Registered campaigners must attribute their spending in proportion to the number of Westminster constituencies in each part of the UK. Unregistered campaigners may wish to attribute their spending in the same way.
