Business Rates: What They Are and How to Calculate Them

Business rates can feel like a minefield for UK small business owners — but ignoring them is not an option. Whether you operate from a high street shop, an office, or even your own home, understanding business rates is vital for budgeting and compliance. This guide explains what business rates are, how they’re calculated, key reliefs and exemptions, and the exact steps to work out what you owe. We’ll tackle common misconceptions, practical pitfalls, and offer clear advice so you can manage this essential cost with confidence.

Business rates are a local tax that businesses pay on most non-domestic properties, such as shops, offices, pubs, warehouses, and factories. The money collected goes to your local council and helps fund local services like street cleaning, policing, and social care. In England and Wales, the system is overseen by the Valuation Office Agency (VOA), while Scotland and Northern Ireland have their own arrangements. If you use a building or part of a building for non-domestic purposes, you’ll almost certainly be liable for business rates, even if you’re running a home business from a dedicated room.

It’s a common misconception that only large businesses or high street retailers pay business rates. In reality, any organisation—be it a limited company, partnership, sole trader, charity, or even a public sector body—can be liable if they occupy commercial premises. Landlords are usually responsible if the property is empty, but once it’s let, the tenant takes over the liability. If you share premises or have a serviced office, check your contract: you might pay rates directly or as part of a service charge.

Some properties are exempt, such as agricultural land and buildings, places of worship, or certain properties used by charities. However, most small businesses operating from a shop, office, or industrial unit will need to factor business rates into their costs. This makes it crucial to understand how rates are assessed and what support is available.

• Most non-domestic properties are liable, including offices, shops, factories, pubs, and warehouses.
• Local councils collect business rates and use them to fund community services.
• Both landlords and tenants can be liable, depending on occupancy and contract terms.
• Certain properties (agricultural, religious, some charitable) are exempt from business rates.
• Small businesses may be eligible for reliefs, but are not automatically exempt.

At its core, your business rates bill is calculated by multiplying your property’s rateable value by a government-set multiplier (sometimes called the 'poundage'). The rateable value is the open market rental value of your property as estimated by the VOA, based on what it could have been let for on a fixed date (currently 1 April 2021 for the 2023 rating list). This figure is reassessed every few years in a process called revaluation.

There are two multipliers in England: the Standard Multiplier and the Small Business Multiplier. For the 2026/27 tax year, the Standard Multiplier is 51.2p, and the Small Business Multiplier is 49.9p. If your property’s rateable value is below a certain threshold (£51,000 in England), you usually qualify for the lower multiplier. Scotland, Wales, and Northern Ireland have their own multipliers and thresholds.

Your final bill may be reduced by reliefs or transitional arrangements, but the basic calculation remains: Rateable Value x Multiplier = Gross Rates Bill. Knowing how your rateable value is set and which multiplier applies is essential for accurate budgeting and checking your bill for errors.

• Rateable value is based on open market rent as assessed by the VOA or equivalent.
• Check your property's current rateable value at www.gov.uk/find-business-rates.
• Multipliers are set annually and published on GOV.UK.
• Reliefs and transitional arrangements can further affect your final bill.

Calculating your business rates bill is straightforward in principle, but several factors can complicate matters in practice. Here’s how to work through the process using up-to-date figures and official sources. Always double-check the details with your local authority or a qualified adviser if in doubt.

Start by finding your current rateable value, determine which multiplier applies, and then check for any reliefs or transitional adjustments. If you’re in a devolved region (Scotland, Wales, or Northern Ireland), be sure to use the relevant rates and reliefs for your area.

Many small businesses are eligible for business rates relief, which can substantially reduce your bill. The most significant is Small Business Rate Relief (SBRR) in England, which offers up to 100% relief on properties with a rateable value up to £12,000, and tapering relief up to £15,000. If you have more than one property, you may still qualify, but only on your main property if the others have rateable values below £2,900 each and their total is under £20,000 (£28,000 in London).

There are also sector-specific reliefs: Retail, Hospitality and Leisure Relief (75% off bills for eligible properties in England in 2026/27, up to a cash cap), Rural Rate Relief for properties in designated rural areas, and charitable rate relief for registered charities and community amateur sports clubs. Empty property relief can apply if your premises are unoccupied, but only for a limited period—usually three months, or six months for industrial premises.

Some properties are entirely exempt, such as agricultural buildings, places of worship, and certain properties used by charities. However, exemptions are tightly defined—don’t assume you qualify without checking the criteria on GOV.UK or with your local authority.

• Apply for SBRR if your rateable value is under £15,000 and you occupy only one property.
• Retail, hospitality, and leisure businesses get temporary discounts—check annual updates.
• Charities and sports clubs can claim up to 80% mandatory relief plus discretionary top-ups.
• Rural businesses should check if their postcode qualifies for rural rate relief.
• Empty properties get limited relief—plan ahead if vacating premises.

Many small business owners pay more than they should—or end up with nasty surprises—because of common misunderstandings around business rates. One frequent error is assuming that if you work from home, you’re always exempt. If you use a room exclusively for business (e.g. as an office, studio, or workshop), the VOA may assess it separately for business rates, even if you also pay Council Tax on the rest of the property.

Another pitfall is not checking the rateable value after a revaluation. The 2023 rating list was based on market rents from April 2021—a period of huge upheaval due to COVID-19. If your property’s rateable value seems high or doesn’t reflect local rents, you have the right to challenge it through the 'Check, Challenge, Appeal' process, but strict deadlines and evidence requirements apply.

Don’t assume your rates bill is set in stone. Reliefs change frequently (especially retail and leisure discounts), and councils sometimes make errors with multipliers or reliefs. Always scrutinise your annual bill, and query anything that looks off. If you move or make alterations, inform the VOA and your council promptly to avoid backdated bills or penalties.

• Don’t ignore your bill—late payment can lead to court action and enforcement.
• Check your rateable value every time a revaluation occurs.
• Apply for all the reliefs you’re entitled to—don’t assume they’re automatic.
• If you sublet or share space, clarify who is responsible for rates in your contract.
• Home businesses may still be liable if you use a room exclusively for business.

Business rates are a devolved matter, meaning each nation in the UK has its own rules, reliefs, and multipliers. While the broad principles are similar, the details can vary significantly—so don’t rely on English guidance if you’re based elsewhere.

In Scotland, the system is called Non-Domestic Rates (NDR). As of 2026/27, the Basic Property Rate (their equivalent of the multiplier) is 49.8p, with higher rates for properties over £51,000 and £100,000. The Small Business Bonus Scheme offers up to 100% relief for properties with a rateable value up to £15,000, but the rules differ from England. In Wales, there’s a single national multiplier and different eligibility criteria for Small Business Rates Relief. Northern Ireland uses a different system altogether, with NAV (Net Annual Value) instead of rateable value, and separate relief schemes.

Always check the official websites for your region or contact your local council for guidance. Reliefs, multipliers, and application processes are reviewed annually and can change at short notice, especially in response to economic events or government policy shifts.

If you believe your rateable value is wrong—perhaps local rents have dropped, part of your property is unusable, or there’s a factual error—you have the right to challenge it. In England and Wales, the process is called 'Check, Challenge, Appeal' (CCA). Begin by checking the details held by the VOA. If you spot an error, submit a 'Check'. If you disagree with their response, move to the 'Challenge' stage, submitting evidence such as rental agreements or photos. The final 'Appeal' stage is for unresolved disputes and may involve the independent Valuation Tribunal.

You must act promptly: there are strict deadlines for each stage, and rateable values can only be changed in limited circumstances. It’s wise to start gathering evidence early—recent local rents, details of changes to your property, and correspondence with your council. If you make alterations, vacate part of your premises, or split/merge units, notify the VOA and your council immediately. Delays can result in unexpected backdated bills or missed opportunities for relief.

Professional rating surveyors can help with complex cases, but beware of unscrupulous firms promising huge savings for a hefty fee. Always check credentials and consider whether the likely reduction justifies the cost. The government maintains lists of reputable agents on GOV.UK.

• Begin with the official 'Check, Challenge, Appeal' process via the VOA.
• Provide clear evidence—recent rents, plans, or photos—to support your case.
• Keep copies of all correspondence and decisions.
• Notify the VOA and your council promptly about occupation changes or alterations.
• Seek professional advice for complex or high-value properties, but beware of scams.

Business rates can be a major overhead, especially for small businesses in city centres or high-value areas. It’s essential to include rates in your cash flow forecasts and to budget for possible increases at each revaluation. If you’re taking on new premises, always check the rateable value and likely rates bill before signing a lease. Ask the landlord or agent for historic bills and clarify who is responsible for payment.

If you’re eligible for reliefs, apply promptly and keep records of correspondence with the council. Set reminders to reapply where necessary, and check for new reliefs and discounts each April, as the government sometimes introduces temporary measures. If your business is seasonal or you’re likely to have periods of vacancy, factor in the limited duration of empty property reliefs.

Cash flow can be tight, especially for startups or businesses with variable income. Most councils offer monthly instalment options—usually 10 or 12 per year. If you’re struggling to pay, contact your council early. They may offer payment plans to avoid enforcement action, which can escalate quickly and damage your credit rating.

• Check the full business rates liability before taking on a lease—not just the rent.
• Build a 3-5% buffer into your cash flow for unexpected rates increases.
• Reapply or check for new reliefs every April after the Budget announcements.
• Keep all bills and correspondence with the council for at least six years.
• Contact your council immediately if you can't pay—don't ignore reminders.
