The commercial property landscape in the UK, particularly within the bustling confines of London, is perpetually dynamic. The recent revaluation of non-domestic properties, effective from April 1, 2026, has sent ripples across the sector. Many businesses are bracing for substantial increases… However, a crucial mechanism is in place to mitigate the immediate impact: the £3.2 billion Transitional Relief Scheme.
Understanding the Revaluation and the Need for Relief
Every few years, the Valuation Office Agency (VOA) undertakes a revaluation of all non-domestic properties in England and Wales. This process adjusts the rateable values (RVs) of properties to reflect changes in the property market.
The latest revaluation, based on property values as of April 1, 2024, will come into effect on April 1, 2026. For many businesses, especially those in areas that have seen significant property value growth like Central London, this means a considerable jump in their rateable values – and consequently, their business rates bills.
Without intervention, these sudden increases could be crippling for businesses already managing tight margins. The government recognised this potential shock and introduced the Transitional Relief Scheme to phase in these increases gradually, allowing businesses time to adjust.
How the Transitional Relief Scheme Works
The core principle of transitional relief is straightforward: it caps the amount by which a business rate bill can change each year following a revaluation. The £3.2 billion fund is specifically designed to manage these caps over a three-year period, from April 1, 2026, to March 31, 2029.
The Annual Increase Caps (2026-2029):
- Small Properties (RV up to £28k in London): Increases capped at a lower percentage each year (historically single digits).
- Medium Properties (RV £28,001 – £100,000): A slightly higher cap will apply here, acknowledging greater capacity to absorb changes.
- Large Properties (RV over £100,000): The annual caps for these properties will be the highest, targeting the greatest support to those who need it most.
Impact on London Office Space
London’s commercial property market has demonstrated remarkable resilience and growth. This growth is precisely why many London-based businesses are facing significant increases in their rateable values.
Consider a tech startup in Shoreditch that saw its rateable value jump by 30% or a financial services firm in Canary Wharf facing a 25% increase. The scheme allows them to spread this increase over three years, providing vital breathing room to budget effectively, adjust operations, and negotiate leases.
