Small Business Rates Relief 2026/27: who qualifies?
The April 2026 revaluation changed many business rates bills. Here is the plain-English guide to the main relief thresholds, the new multipliers and what to check if your bill has increased.
Polar in 30 seconds
In England, small business rate relief may be available when your property has a rateable value below £15,000 and your business normally uses only one property. A property with a rateable value of £12,000 or less can receive 100% relief, while relief tapers between £12,001 and £15,000. If you lost relief after the 1 April 2026 revaluation, supporting small business relief may limit the increase.
What changed in 2026?
A business rates revaluation took effect in England and Wales on 1 April 2026. The Valuation Office updated rateable values using estimated open-market rental values from 1 April 2024. A changed rateable value does not automatically mean the same percentage change in your final bill because multipliers and reliefs also matter.
For England from 1 April 2026 to 31 March 2027, GOV.UK lists a small business multiplier of 43.2p and a standard multiplier of 48p. A separate 38.2p multiplier applies to qualifying retail, hospitality and leisure properties below £51,000 rateable value.
Who can get small business rate relief?
Rateable value up to £12,000
If it is the only property your business uses, you will normally pay no business rates because the relief is 100%.
£12,001 to £15,000
The relief reduces gradually. GOV.UK gives examples of 50% relief at £13,500 and 33% at £14,000.
Below £51,000
Even without small business rate relief, the lower small business multiplier may apply.
More than one property
Extra rules apply. Businesses taking a second property on or after 27 November 2025 can keep relief on the main property for 36 months.
What is supporting small business relief?
If the 2026 revaluation caused you to lose some or all of your small business rate relief, you may qualify for supporting small business relief. For eligible businesses, the increase for 2026/27 is capped by rules based on the previous bill and the property’s rateable value. Your council should apply the adjustment if you qualify.
Your five-step check
- Find the rateable value shown on your latest business rates bill.
- Compare it with the current Valuation Office record for the property.
- Check whether small business rate relief or a lower multiplier appears on the bill.
- Ask your council whether supporting small business relief applies if your relief fell after April 2026.
- Put the full rates cost into your cash-flow forecast rather than relying on last year’s figure.

The Polar view
Business rates are a fixed cost that can quietly distort pricing and cash flow. Check the bill, confirm every available relief and then use the real annual figure in your forecasts and prices.
