What is Supporting Small Business relief 2026?

Checked against the rating list and the rules in force as at 2026-08-23.

In short

Supporting Small Business relief 2026 is for ratepayers who lost some or all of their small business rate relief, or rural rate relief, because their rateable value rose at the April 2026 revaluation. It caps the increase in the bill at £800 a year, or the transitional relief percentage if that is higher. Your council applies it automatically. On the 2026 list, 9,390 London retail, hospitality and leisure premises moved from £12,000 or below to above it, and those are the premises it is aimed at.

Who it is for

You had small business rate relief or rural rate relief on 31 March 2026, and the new rateable value took some or all of it away. That includes moving from the full band into the tapered band, and moving out of the tapered band altogether.

It also covers ratepayers who lost retail, hospitality and leisure relief or 2023 supporting small business relief at the revaluation, on the terms your council publishes.

What it does

The bill can rise by no more than £800 a year, or by the transitional relief percentage for the band if that is a larger amount. The scheme runs from 2026/27 to 2028/29. Anyone who was still on the 2023 scheme on 31 March 2026 gets the 2026 scheme for one year only, to 31 March 2027.

It is applied by your council without an application. It shows as its own line on the bill.

How many London premises crossed the line

We compared the 2023 and 2026 rateable values of every London retail, hospitality and leisure premises. 9,390, or 8.6%, were at £12,000 or below on the 2023 list and are above it on the 2026 list. In Sutton it is 20.9% of premises, in Bromley 15.4%, in Barking and Dagenham 14.9%. In the City of London it is 0.5%, in Westminster 1.4%.

These are premises whose value crossed the line. Whether the occupier held the relief before, and so qualifies for the cap now, is on the bill and not in the public data.
