Business Rates in the UK: What They Are and How to Reduce Them
The tax on commercial property that catches out businesses taking their first premises — including several reliefs that go unclaimed.
Business rates are a tax on most non-domestic property, and they are frequently the second largest fixed cost after rent. Businesses taking premises for the first time are routinely surprised by them, because they are billed separately from rent and are not always mentioned during negotiation.
How the Bill Is Calculated
Each property has a rateable value, set by the Valuation Office Agency and based broadly on an estimate of open market annual rent at a fixed valuation date. The bill is that value multiplied by a multiplier set by government, then adjusted for any reliefs that apply.
The valuation date is historic and revalued periodically, which means your rateable value may not reflect current market rent. That works both ways.

Relief is available for properties below a rateable value threshold, and at the lower end it can remove the bill entirely. It generally applies where you occupy a single property. It is not always applied automatically, so check your bill and contact the local authority if it is missing — this is the most commonly unclaimed relief.
Other Reliefs Worth Checking
Depending on circumstances there are reliefs for rural businesses, charities, empty properties for a limited period, and sometimes discretionary relief at the local authority’s discretion. Retail, hospitality and leisure schemes have run at various points. Availability and thresholds change, so check the current position with your local council rather than relying on published summaries.
Check Your Rateable Value Is Right
You can view the valuation for your property and the evidence behind it. Errors happen — wrong floor area, wrong description, wrong classification — and they are worth correcting because the bill follows the valuation. There is a formal process for challenging it.
Beware Firms Charging to Do This
Rating agents contact businesses offering to reduce bills for a fee or a share of savings. Some are legitimate; many charge for work you can do yourself free through the official channel. Be particularly cautious of anyone requiring payment upfront or a long contract.
Working From Home
Home working does not usually trigger business rates, but it can where part of the property is used exclusively for business or has been adapted, such as a converted outbuilding or a shop front. If you are unsure, ask rather than assume, because backdated liability is unpleasant.
Empty Property Still Costs
An empty commercial property attracts rates after an initial exemption period. Businesses that take premises and then downsize sometimes find themselves paying for space they no longer use, which is a reason to think carefully about lease length before committing.
Factor It Into Any Premises Decision
When comparing sites, compare rent plus rates plus service charge rather than rent alone. A cheaper rent in a higher-rated location can cost more overall. Include the figure in your cash flow forecasting forecast as a real monthly cost, since most authorities allow payment by instalments across the year.
Who Is Liable for the Bill
Liability generally falls on the occupier rather than the owner, which means a tenant is usually billed directly rather than through the landlord. Establish this before taking premises, because a rent figure that sounds affordable can look very different once rates are added on top of it.
Transitional Arrangements After Revaluation
When rateable values are reassessed, schemes frequently phase large increases and decreases over several years rather than applying them at once. This means your bill may not reflect your current rateable value directly, and a reduction you expected may arrive gradually.
Splitting or Combining Space
Taking additional adjacent space, or subletting part of what you occupy, can change how the property is assessed and may affect eligibility for small business relief, which generally depends on occupying a single property. Check the consequences before rearranging occupancy.
Appeals Take Time
Challenging a valuation follows a defined process with stages and deadlines, and it is not quick. Importantly, you must generally keep paying the existing bill while a challenge is ongoing. Withholding payment because you are disputing the valuation causes recovery action regardless of the merits.
Check the Bill Itself Every Year

Bills are issued annually and errors persist unless someone notices. Verify the rateable value used, the period covered, the reliefs applied and the instalment plan. A relief that was applied last year does not always carry forward automatically, particularly after a change of occupier or a revaluation.
Budget It as a Fixed Monthly Cost
Rates do not flex with trade. In a quiet month they arrive unchanged, which is exactly what makes fixed premises costs risky for seasonal businesses. Treat the annual figure divided across the year as a committed cost in the same category as rent.
Reliefs Are Not Always Automatic
Some reliefs are applied by the authority once it knows the circumstances; others require an application. Assuming a relief will appear because you appear to qualify is how businesses overpay for years. Read the bill line by line and ask if something you expected is missing.
Rates Follow the Property, Not the Business
Liability attaches to occupation of a specific property, so two locations mean two bills, and moving mid-year means an apportionment. This also affects relief eligibility, since some schemes depend on occupying only one property.
Rates Are Devolved
The system differs across the UK. Scotland, Wales and Northern Ireland each set their own multipliers and relief schemes, and thresholds do not match those in England. Guidance written for one nation can be misleading elsewhere, so check the rules for where your property actually sits.
Tell the Council When Things Change
Moving in, moving out, altering the property or changing how it is occupied can all affect liability, and the obligation to notify generally sits with you. Businesses that vacate without telling the authority frequently keep receiving bills, and sorting it out retrospectively is slower than a phone call at the time.
If You Cannot Pay
Contact the local authority before missing a payment. Recovery for unpaid rates is relatively swift, and authorities are considerably more willing to discuss an arrangement in advance than after enforcement has begun.
