Revaluation 2026
All rateable values are reassessed at a general revaluation to ensure rates paid by any one ratepayer reflect changes over time in the value of their property relative to others. This helps maintain fairness in the rating system by updating valuations in line with changes in the market.
The current rating list came into effect on 1 April 2026 and is based on values as at 1 April 2024.
In the year a revaluation takes effect, the multiplier is rebased to account for overall changes to total rateable value and to ensure that the revaluation does not raise extra money.
How to appeal against your rateable value

When you contact them, you need to tell them the reasons why you think your rateable value is wrong.
They will compare your rateable value with similar properties in the area and consider any other reasons you have mentioned when they check the rateable value for you.
If you do not agree with the outcome of the discussions, you can make an appeal against the rateable value.
