Revaluation of rateable value
Assessors check and calculate rateable values every 3 years to reflect changes in the property market. This process is known as a 'revaluation'.
For most properties, rateable value is based on an estimate of their rental value. Assessors take rental values from the same point in time, known as the 'tone date'.
The last revaluation was in 2026. The tone date for this was 1 April 2025.
The next revaluation will be in 2029. The tone date for that will be 1 April 2028.
Your rateable value will usually stay the same until the next revaluation, unless there are changes to your business or premises.
How assessors calculate rateable values
Assessors use different methods to calculate rateable values. For example, they might use information such as rent or floor space. They’ll usually ask property owners, tenants or occupiers for this information. This is to make sure the calculations are as accurate as possible.
Assessors will contact you for this information. You need to give it by law. You may be fined if you do not. Contact your local assessor right away if you do not have the information they ask for.
Getting a new rateable value at the 2029 revaluation
The assessor will write to you about the revaluation of your property.
You’ll get:
- an estimate of your new rateable value (a 'draft valuation notice') once the draft valuation roll is published on 30 November 2028
- confirmation of your new rateable value (a 'valuation notice') that applies from 1 April 2029 – this might be different from the draft value
There’s more information about valuation notices on the Scottish Assessors Association website.
You can seek to pre-agree the rateable value before a revaluation. Contact your assessor if you want to discuss this.

If you think your draft valuation notice is wrong
Contact your local assessor to explain why you think the estimated value is wrong. This is called 'making representations'. For example, you might argue that changes to your property have affected its rental value.
The assessor may adjust your rateable value because of the information you give them.
You can find your assessor’s contact details on the Scottish Assessors Association website. They’re also included on your draft valuation notice.
If you think your current rateable value is wrong
If you think your current rateable value is wrong, you can ask your local assessor to check it. You’ll need to provide evidence to support your claim. This is called ‘making a proposal’.
If you still disagree with the assessor’s decision about your proposal, you can usually make an appeal.
You must make your proposal or appeal within a certain time.
