To find out your Council Tax band for a property in England or Wales, you can look up its address or postcode on the GOV.UK website. For properties in Scotland, you can search on the Scottish Assessors website. You can also use this service to challenge your Council Tax band if you think it's wrong, and you'll need to provide evidence for your challenge. The valuation band for properties in England and Wales is based on their value on 1st April 1991, and it determines how much Council Tax you pay. If you want further details about your banding, you can visit the Valuation Office Agency (VOA) website, call them on 03000 501501, or email them at [email protected]
