Non-domestic rates guidance

If your business or premises change

Last updated
30 Mar 2026

Your non-domestic rates bill could change if:

  • you move
  • the property you own becomes empty
  • the nature of your business changes
  • there are ‘material changes’ to your premises

Material changes could include:

  • physical changes to your property – for example expansion or demolition
  • new roads or changes to access routes
  • events that affect your business – for example a fire in your area

You must tell your local assessor about any changes. This helps to ensure you're paying the right amount and do not get a backdated increase in your bill.

You must also tell your local council if the occupier of a property changes or if your property becomes empty. You must do this within 42 days or you may get a fine of £370.

If you're moving to new premises, you can use our non-domestic rates calculator to estimate your non-domestic rates bill.

Contact your local council about non-domestic rates
