Comprehensive Guide: How Rateable Value is Calculated in the UK
The rateable value of a property is a fundamental concept in the UK’s business rates system. It represents the rental value of a property at a specific date, adjusted for various factors, and serves as the basis for calculating business rates. This comprehensive guide explains how rateable values are determined, the factors that influence them, and how they impact your business rates bill.
What is Rateable Value?
Rateable value is an assessment of the annual rent a property could reasonably be expected to achieve on the open market, assuming:
- The property is available to let
- The landlord pays for insurance, repairs, and other costs
- The tenant pays all other occupier costs
- The valuation date is fixed (currently 1 April 2021 for the 2023 revaluation)
This value is determined by the Valuation Office Agency (VOA) in England and Wales, or the Scottish Assessors in Scotland. The rateable value is then used to calculate your business rates bill by multiplying it by the appropriate multiplier (also called the ‘poundage’).
The Valuation Process
The VOA uses a standardized approach to value properties:
- Rental Analysis: Valuers examine rental evidence for similar properties in the area
- Property Inspection: Physical characteristics are recorded (size, age, condition, etc.)
- Comparative Adjustment: The property is compared to others with known rental values
- Tone of the List: Ensuring consistency across similar properties
- Final Determination: The rateable value is set and entered into the rating list
Key Factors Affecting Rateable Value
Several factors influence a property’s rateable value:
| Factor | Impact on Rateable Value | Weighting |
|---|---|---|
| Location | Prime locations command higher rents | High |
| Size | Larger properties generally have higher values | High |
| Property Type | Retail often higher than industrial per sq ft | Medium |
| Condition/Age | Modern, well-maintained properties valued higher | Medium |
| Accessibility | Good transport links increase value | Medium |
| Local Economy | Strong local economy supports higher rents | Low-Medium |
The 2023 revaluation used rental values as at 1 April 2021. This means that even if market rents have changed significantly since then, your rateable value won’t reflect those changes until the next revaluation (currently scheduled for 2026).
How Business Rates are Calculated from Rateable Value
The formula for calculating business rates is:
Rateable Value × Multiplier = Annual Business Rates Bill
There are two multipliers:
- Standard multiplier (2024/25): 54.6p (for properties with RV ≥ £51,000 in England)
- Small business multiplier (2024/25): 49.9p (for properties with RV < £51,000 in England)
For example, a property with a rateable value of £20,000 would pay:
£20,000 × 0.499 = £9,980 per year
| Rateable Value Band | 2024/25 Annual Rates (England) | Monthly Cost |
|---|---|---|
| £10,000 | £4,990 | £416 |
| £20,000 | £9,980 | £832 |
| £50,000 | £27,300 | £2,275 |
| £100,000 | £54,600 | £4,550 |
| £250,000 | £136,500 | £11,375 |
Appealing Your Rateable Value
If you believe your rateable value is incorrect, you can challenge it through the VOA’s “Check, Challenge, Appeal” process:
- Check: Verify your property details are correct on the VOA website
- Challenge: If you disagree with the valuation, submit evidence (rental comparisons, property details)
- Appeal: If still unsatisfied, appeal to the Valuation Tribunal
Common grounds for appeal include:
- Incorrect property details (size, layout, facilities)
- Changes in the local area that affect value
- Evidence that similar properties have lower rateable values
- Physical changes to the property that reduce its value
Note that you can’t appeal just because you think the rates are too high – you must demonstrate that the rateable value itself is incorrect.
Recent Changes and Future Trends
The 2023 revaluation brought several important changes:
- Based on rental values from April 2021 (pre-pandemic recovery)
- More frequent revaluations (every 3 years instead of 5)
- New “improvement relief” for property improvements
- Expanded retail relief (though now ended for most properties)
Looking ahead, we can expect:
- More frequent revaluations to keep pace with market changes
- Potential reforms to the multiplier system
- Increased use of digital valuation tools by the VOA
- Possible changes to relief schemes for struggling sectors
Practical Tips for Business Owners
To manage your business rates effectively:
- Review your valuation: Check your rateable value when you move into a property and after any revaluation
- Claim reliefs: Ensure you’re claiming all eligible reliefs (small business, retail, rural, etc.)
- Monitor changes: Stay informed about revaluations and legislative changes
- Consider appeals: If your circumstances change significantly (e.g., flood damage, local economic decline)
- Plan for costs: Budget for rates as a fixed cost in your financial planning
- Seek advice: Consult a rating surveyor for complex properties or large potential savings
Remember that business rates are a significant overhead for many businesses – typically representing about 50% of the rent for smaller properties and 30-40% for larger ones. Proper management of your rateable value can lead to substantial savings.
