Business Rates for Offices: A Complete UK Guide

If you occupy an office, you pay business rates on it — the tax on non-domestic property — and for 2026/27 offices are charged at the standard multipliers of 43.2p (small) or 48p in the pound. Unlike shops, pubs and gyms, offices do not qualify for the new lower retail, hospitality and leisure (RHL) multipliers, so an office and a café with the same rateable value now pay different amounts. That makes it especially important for office occupiers to make sure they are not overpaying: checking the rateable value, claiming Small Business Rate Relief where it applies, and challenging an over-assessment can all cut the bill. With 2026 also being a revaluation year — and office values shifting as hybrid working reshapes demand — this is a good moment to review. This guide explains exactly how office business rates work, what reliefs you can get, and how to reduce them.

What office business rates are

Business rates are a tax on the occupation of non-domestic property, and an office is a textbook example. If your business occupies office space — whether a single room, a floor, or a whole building — you are generally liable for business rates on it. In most commercial leases the tenant pays the rates directly to the local council, not the landlord, so for the great majority of office occupiers this is a cost they manage themselves. The bill is based on the office’s rateable value and the national multiplier, then reduced by any reliefs. Rates are one of the larger fixed costs of occupying an office, which is exactly why it pays to make sure the figure is right.

How office business rates are calculated

The calculation is the same for offices as for any property: rateable value × multiplier = annual charge, before reliefs. The rateable value is set by the Valuation Office Agency and broadly reflects the office’s open-market annual rent at a set valuation date. The multiplier is a nationally set figure in pence in the pound. So an office with a rateable value of £40,000, charged at the 43.2p small business multiplier, has a bill of £40,000 × 0.432 = £17,280 a year before any relief. Because there are only three moving parts — rateable value, multiplier and reliefs — reducing your office rates always comes down to checking each one is correct.

The 2026/27 multipliers for offices

From 1 April 2026 there are five national multipliers, and offices fall under the standard ones (the small business multiplier below £51,000 rateable value, the standard multiplier at or above it, and the high-value multiplier from £500,000):

Note that the lower RHL multipliers of 38.2p and 43p do not apply to offices. Confirm your bill uses the correct standard multiplier for your rateable value band, because the jump from 43.2p to 48p at £51,000 is significant.

Why offices miss the RHL discount

From 2026, retail, hospitality and leisure properties get permanently lower multipliers (38.2p and 43p) to support the high street. Offices are deliberately excluded: they are not “wholly or mainly used” for retail, hospitality or leisure, so they pay the standard rate. This creates a real difference — a shop and an office with identical rateable values now pay 5p in the pound apart. For most pure offices there is no way around this; the standard multiplier applies. The exception worth checking is genuinely mixed-use premises (for example an office above or attached to a qualifying retail or leisure use), where the classification can be more nuanced and worth examining. For a straightforward office, though, the standard multiplier is correct, and the savings come from reliefs and an accurate rateable value instead. Our guide to RHL business rates explains who does qualify.

The 2026 revaluation and offices

2026 is a revaluation year, with new rateable values taking effect from 1 April 2026 based on more recent rental evidence. This matters especially for offices, because the office market has changed dramatically: hybrid and remote working has reduced demand for some space and shifted it towards smaller, higher-quality or better-located premises. As a result, office rateable values have moved — down in some areas and categories, up in others — independently of the multiplier changes. Do not assume your office bill simply rose or fell; check the new rateable value against the rent you actually pay and against comparable nearby offices. A revaluation is the single best moment to spot and correct an over-assessment, because the figure is fresh and a challenge is in time.

Small Business Rate Relief for offices

Small Business Rate Relief (SBRR) is the most valuable relief for small offices and frequently removes the bill entirely. If your office has a rateable value of £12,000 or less, you generally pay no business rates at all. Between £12,001 and £15,000 the relief tapers from 100% down to 0%. SBRR generally applies where you occupy only one property, with limited exceptions for additional small properties. Many small consultancies, agencies and professional firms occupy offices within the SBRR threshold and are entitled to pay nothing — but the relief is not always applied automatically, so it is worth confirming with your council that you are receiving it. For small office occupiers, this is the first thing to check, because it can make every other consideration academic.

Other reliefs an office can claim

Beyond SBRR, a few reliefs can apply to offices in the right circumstances:

Offices do not get the RHL multiplier or rural relief in the way shops can, so the practical reliefs are SBRR for small offices, empty-property relief for vacant space, and transitional relief to soften a revaluation jump. Reviewing your eligibility across these is where overlooked savings are found.

Empty office rates

Empty offices are a common cost trap. When an office becomes empty, there is generally a three-month rates-free period, after which empty-property rates — typically the full charge — become payable, with some exemptions for particular cases. With hybrid working leaving many businesses holding surplus space, this matters more than ever: a floor you no longer need can keep generating a full rates bill once the void period ends. Options include genuinely reletting or subletting the space, formally vacating part of the building, or in some cases applying for relief on an empty part of a property that is otherwise occupied. These areas carry anti-avoidance rules and need careful handling, but for businesses carrying surplus office space the savings can be significant. Always notify the council promptly when space becomes empty, because relief periods usually run from notification.

How an office’s rateable value is set

For most offices, the Valuation Office Agency assesses rateable value by reference to rent per square metre, adjusted for the size, location, specification and condition of the space, using rental evidence from comparable offices. Factors such as floor area, the quality of the building, car parking, air conditioning and the strength of the location all feed in. This is why an accurate record matters: if the floor area is overstated, or the office is recorded as a higher specification than it is, the rateable value — and your bill — will be too high. Checking the details the Valuation Office Agency holds about your office, and comparing your rateable value with similar nearby offices, is the foundation of making sure you are not overpaying.

How to reduce your office business rates

There are several legitimate levers, and most office occupiers find a saving in at least one:

• Check the rateable value on the Valuation Office Agency service and confirm the floor area and details are correct.
• Claim Small Business Rate Relief if your rateable value is £15,000 or under and you occupy one property.
• Confirm the correct multiplier for your rateable value band (43.2p, 48p or 50.8p).
• Use empty-property relief for any genuinely vacant space, and tell the council promptly.
• Claim transitional relief if the 2026 revaluation pushed your bill up sharply.
• Challenge an over-assessment through Check, Challenge, Appeal, with evidence on comparable rents.

A successful reduction in rateable value lowers your bill every year until the next revaluation, so the effort repeats its value many times over.

Business rates vs rent: the true cost of an office

When businesses budget for an office, they often focus on the rent and treat rates as an afterthought — but for many offices the business-rates bill is a substantial fraction of the rent, and occasionally rivals it. Because rates are calculated from a rateable value that itself reflects rental value, a high-rent office generally carries a high rates bill too. The two together are the real cost of occupation, alongside service charges and utilities. This matters when you compare offices or negotiate a lease: a slightly cheaper rent in a higher-rated location can end up costing more overall once rates are added. The practical lesson for any business taking office space is to model rent and rates together as a combined occupancy cost, and to factor in any Small Business Rate Relief or revaluation effect, rather than letting the rates bill arrive as a surprise after you have signed.

Office rates and your lease

Who pays the rates on an office is a question of occupation and of what the lease says. As the rateable occupier, the tenant is generally liable to the council for business rates — and most commercial leases, including the common “full repairing and insuring” (FRI) lease, make this explicit by requiring the tenant to pay all rates and outgoings. That means budgeting for rates is the tenant’s job from day one, and it continues even during rent-free periods at the start of a lease, when rates are still payable. It also has consequences at the end: if you remain in occupation, you remain liable. Before taking an office, check the lease’s wording on rates and outgoings, confirm the current rateable value and likely bill, and treat both as part of your committed cost. A clear understanding of the rates position avoids disputes with the landlord and unwelcome surprises with the council.

An annual office-rates review

Office rates reward a little regular attention. Once a year — and especially around the 2026 revaluation — it is worth running a short review: pull your latest bill and note the rateable value, the multiplier and any reliefs; check the rateable value and the recorded floor area on the Valuation Office Agency service; confirm you are receiving Small Business Rate Relief if your rateable value is £15,000 or under; flag any empty or surplus space to the council; and decide whether the rateable value is worth challenging. For a business with one office this takes minutes; for one with several offices, or with surplus space following a move to hybrid working, the potential savings justify a more thorough look, possibly with a rating surveyor. The key is that every error you correct keeps saving money for as long as you hold the office, so the review pays for itself many times over.

Serviced offices, co-working and hybrid space

How rates are handled depends on how you occupy the space. In a serviced office or co-working space, business rates are usually built into the all-inclusive fee you pay the operator, who is the rateable occupier — so you do not receive a separate rates bill, though the cost is reflected in your monthly charge. In a conventional leased office, you are normally the rateable occupier and pay rates directly. Hybrid arrangements — taking less space, or flexible memberships — change who is liable and how, so it is worth understanding the rates position before you commit to a particular type of space. For a growing business weighing serviced versus leased offices, the rates treatment is part of the true cost comparison, not an afterthought.

Worked example: two offices, two outcomes

A two-person consultancy occupies a small office with a rateable value of £11,000. Because that is under £12,000 and it is their only property, Small Business Rate Relief wipes the bill out entirely — they pay nothing. A larger agency occupies a city-centre office with a rateable value of £70,000. That is above £51,000, so the standard 48p multiplier applies: £70,000 × 0.48 = £33,600 a year, with no RHL discount available. After the 2026 revaluation the agency checks its rateable value, finds the floor area overstated, and a successful challenge reduces it — cutting the bill for every future year. The contrast shows the two routes to a lower office bill: relief for small offices, and an accurate rateable value for larger ones.

How office rates shape relocation and downsizing decisions

Business rates increasingly influence the big property decisions, not just the annual budget. With hybrid working, many businesses now hold more office space than they use, and the rates on that surplus space — payable in full once any empty-rates void period ends — can tip the balance towards downsizing or relocating. When weighing a move, the rates position deserves the same scrutiny as the rent: a smaller office, or one in a different rating band, can cut the combined occupancy cost substantially, and crossing back under the £51,000 rateable-value threshold moves you from the 48p standard multiplier to the 43.2p small business multiplier. Equally, dropping to a rateable value of £12,000 or less can remove the bill entirely through Small Business Rate Relief. Before committing to new space or surrendering old space, model the rates outcome of each option — including any empty-rates liability on space you are leaving behind until it is relet or the lease ends. Treating rates as a live factor in property strategy, rather than a fixed cost you simply absorb, is how well-run businesses keep their occupancy costs under control as working patterns change.

Common mistakes to avoid

• Expecting the RHL discount. Offices pay the standard multiplier, not the lower RHL rate.
• Not claiming Small Business Rate Relief. A rateable value of £12,000 or less usually means no bill.
• Paying full rates on empty space. Use the void period and tell the council promptly.
• Ignoring the 2026 revaluation. Office values have shifted — your rateable value may be wrong.
• Overlooking an overstated floor area. Check the details the Valuation Office Agency holds.
• Assuming the landlord handles rates. In most leases the tenant pays and must manage them.

London offices: a quick note

London office rateable values are among the highest in the country, so the thresholds bite hard: many London offices sit above £51,000 (the 48p standard multiplier) and some above £500,000 (the 50.8p high-value multiplier), where the bill is substantial and there is no RHL relief to soften it. The 2026 revaluation has also moved London office values significantly as occupiers rethink space. For London office occupiers, carefully checking the rateable value, the applied multiplier and any over-assessment after the revaluation can produce savings that recur every year — and the larger the office, the bigger the prize.

What we see in practice

The point office occupiers most often miss is that offices get none of the headline retail reliefs. They do not qualify for Retail, Hospitality and Leisure relief, so from 1 April 2026 an office is charged on the standard non-RHL multiplier — and any property, including a large office, with a rateable value of £500,000 or more pays the new higher multiplier of 50.8p for 2026/27. For occupiers near that threshold the 2026 revaluation figure is worth checking early.

The other recurring issue is space you pay for but barely use. Offices are valued largely on net internal area, so storage, plant rooms and vacant floors all feed the rateable value. Where part of a building is genuinely unused, it is sometimes possible to ask the Valuation Office Agency to split the assessment or reflect the disrepair, and empty-rates relief may apply to a clearly separable empty part. We look at the floor plan, not just the bill.
