Understanding UK Business Rates (2024/25)
Business rates are a tax charged on most non-domestic properties in the UK, such as shops, offices, pubs, warehouses, and factories. The amount you pay is primarily calculated based on your property's Rateable Value (RV).
The Basic Formula:
Business Rates = Rateable Value (RV) × Multiplier
1. What is Rateable Value?
The Rateable Value is an estimate by the Valuation Office Agency (VOA) of how much your property would rent for on the open market annually. For the 2024/25 tax year, this is based on rental values as of 1 April 2021.
2. The Multiplier
The multiplier is the number of pence per pound of Rateable Value that you must pay. There are two standard multipliers in England for 2024/2025:
Small Business Multiplier: 49.9p (0.499) – Applies if your RV is below £51,000.
Standard Multiplier: 54.6p (0.546) – Applies if your RV is £51,000 or higher.
3. Small Business Rate Relief (SBRR)
If your property's Rateable Value is less than £15,000 and it is your only business property, you may qualify for Small Business Rate Relief:
RV up to £12,000: You get 100% relief. You pay £0.
RV between £12,001 and £15,000: The relief is tapered from 100% down to 0%.
RV over £15,000: No SBRR is available, though the Small Business Multiplier still applies up to £51,000.
Calculation Example
Imagine you have a shop with a Rateable Value of £13,500 and it is your only property.
Multiplier: Since RV < £51,000, we use 49.9p.
Gross Bill: £13,500 × 0.499 = £6,736.50.
Relief Calculation: Since £13,500 is halfway between £12,000 and £15,000, you get 50% relief.
Relief Amount: 50% of £6,736.50 = £3,368.25.
Total Payable: £6,736.50 – £3,368.25 = £3,368.25 per year.
