2026 Revaluation

On the 1st April 2026, the new rating list will go live, reflecting changes in rental values from April 2021 until April 2024.

The purpose of the revaluation is to redistribute the property tax base to reflect rental changes in the commercial property market. Properties that have witnessed rental value increases will see an increase in their rateable values and the converse applies to properties with rental falls.

At Knight Frank we have used our extensive market knowledge to carry out a series of research articles across the various sectors. These will inform businesses of not only the likely changes to their sectors but also provide an insight into other important changes to the rating system.

For the first time, all our research can be viewed on an interactive map, allowing users to look at how their liabilities may change in 2026 across a variety of sectors and locations.

Our first research article covers the Central London office market. You can view the data on our interactive map and read our article below.

We will be publishing additional research and data on other submarkets over the next few months and recommend you bookmark this page or email us to subscribe to our bulletins at rating@knightfrank.com.
