Business rates for self storage (UK)

Business rates are the tax almost every new storage operator under-budgets — and one of the few running costs that arrives whether the site is full or empty. They are charged on non-domestic property, billed by your local council, and calculated from two numbers: the rateable value the Valuation Office Agency (VOA) assigns to your property, and a multiplier the government sets for each tax year. A storage facility is rateable like any other commercial premises, and a new operator who budgets zero for rates is planning with a hole in the plan.

This guide explains how the system works for a storage business in England in 2026: where rateable values come from, the current multipliers, the relief that takes many small sites out of the bill entirely, how new and growing sites get assessed, and what to do when a valuation looks wrong. It is part of our wider guide to starting a self storage business in the UK.

What business rates are

Business rates — formally non-domestic rates — are the commercial counterpart of council tax. If you occupy property for non-domestic purposes, a storage yard included, your local council sends an annual bill, normally payable in monthly instalments, and the money funds local services. The calculation is mechanical:

rateable value × the year's multiplier − any reliefs = your annual bill

Two properties of the tax matter for a storage business plan. First, it is a tax on the property, not on profits: the bill takes no interest in your turnover, your margins or your occupancy. Second — the consequence worth internalising — an empty-but-open site pays what a full one pays. Rates are a fixed cost that lands hardest during the fill-up phase, exactly when revenue is thinnest.

Rateable value: what the VOA is measuring

The VOA, an agency of HMRC, maintains the rating list — the register of every non-domestic property and its rateable value. A rateable value is the VOA's professional estimate of the property's open-market annual rental value at a fixed valuation date. It is not what you paid for the site, not what you spend on it, and not your revenue; it is what the property could reasonably let for on the standard assumptions the rating system uses.

Values are refreshed periodically by revaluation to keep the list in line with the market: a new rating list took effect in England on 1 April 2026 (per gov.uk, checked July 2026), so current assessments are freshly revalued. You can look up any property's rateable value — yours, or usefully a nearby competitor's — free of charge through the VOA's find-a-business-rates-valuation service on gov.uk, which is the quickest way to get a realistic feel for what storage sites in your area carry before you commit to one.

The rateable value is not the bill. It is the input the multiplier turns into one.

England's multipliers for 2026-27

The multipliers below are the verified figures from gov.uk's business-rates guidance ("Estimate your business rates", checked July 2026), applying from 1 April 2026 to 31 March 2027:

Multiply your rateable value by the applicable figure and you have the gross annual bill, before relief. Two notes for storage operators. First, most independent sites — certainly most container yards and farm stores — will sit below £51,000 and pay 43.2p. Second, 2026-27 also introduced lower multipliers for eligible retail, hospitality and leisure properties (38.2p below £51,000 and 43p from £51,000 to £499,999, per the same gov.uk page). Eligibility for that category is specifically defined, and a storage facility is not the retail, hospitality or leisure business it is aimed at — plan on the standard multipliers unless your council tells you otherwise.

Small business rate relief

For new operators this is the relief that matters, and at the small end it can eliminate the bill. Per gov.uk's small business rate relief guidance (checked July 2026):

• 100% relief — no rates at all — on a property with a rateable value of £12,000 or less, where that is the only property the business uses.
• Tapered relief from £12,001 to £15,000. The percentage falls gradually across the band; gov.uk's own worked examples put it at roughly 50% relief at a £13,500 rateable value and 33% at £14,000.
• Above £15,000, no relief — though below £51,000 you still pay the lower 43.2p multiplier rather than the standard one.
• Taking on a second property does not end relief immediately. You keep it on the main property for 36 months where the second property is acquired on or after 27 November 2025 (12 months for earlier acquisitions) — and can keep it beyond that if none of the other properties has a rateable value above £2,899 and the combined total stays under £20,000 (£28,000 in London).

For a small first site this is a serious number. A compact container yard or single farm store assessed at £12,000 or less can legitimately pay nothing in rates for as long as it remains the business's only property. The relief is claimed through your local council rather than arriving automatically — so ask, and never assume it has been applied.

How a new storage facility gets assessed

A property enters or changes in the rating list a few ways. For a newly built facility, the council can issue a completion notice that brings it into the list. For a conversion or a change of use — a yard becoming a container site, a barn becoming a store — the VOA typically picks the change up from planning records and council reports, or you can tell it directly through your online business rates valuation account.

Two practical realities follow. Assessment can lag the opening of your site, sometimes by months — and when the bill arrives it can be backdated to the date your liability began. A quiet first year is a deferral, not an exemption: budget rates from the day the gates open and treat any delay in billing as money you are holding for the council, not money you have saved.

One line for farm operators, because it catches people every year: an agricultural building is exempt from business rates only while it is in agricultural use — put it to paid storage and the exemption ends and the building becomes rateable, a principle set out in the VOA's own rating guidance and covered further in our farm diversification guide.

Container sites: questions for the VOA

Container yards occupy a genuinely nuanced corner of the rating system. The unit being assessed is fundamentally the land you occupy for the business, and how a valuation treats the containers themselves — moveable stock from your point of view, potentially part of the rateable whole from the VOA's — is a fact-specific question this guide is not going to pretend has one general answer. What is certain is the direction: land occupied for a paid-storage business is rateable, and "the containers are moveable" does not make the site free of rates.

The productive move is to put the questions to the VOA — or to a reputable rating surveyor — early, rather than assume:

• What will the assessment for this site be based on: the land, the hardstanding and works, the containers, or all of them together?
• How will phased growth be handled? A 20-container yard and the same yard at 60 containers are different propositions — expect the valuation to be revisited as the site densifies, and report material changes rather than waiting to be found.
• From what date would the site enter the list, and from what date would liability run?

Asking first costs nothing. An unbudgeted, backdated bill is the avoidable version of this story.

A worked example

The rateable values below are invented for illustration — real ones come from the VOA and vary enormously with location, site quality and size. The multipliers and relief percentages are the verified England 2026-27 figures above.

The farm store is why so many farm and small-yard operators pay nothing. The container yard is the one to internalise: a mid-sized independent site can carry a four-figure monthly rates bill, and it belongs in your fixed costs next to the cost of the site itself. (The £14,000 case: £14,000 × 43.2p = £6,048 gross; ≈33% relief leaves ≈£4,050.)

The four nations diverge

Business rates are devolved, and the figures in this guide are England’s.

A storage business outside England should treat this guide as a map of the concepts — rateable value, multiplier, relief — and take every figure from its own nation's guidance.

Do storage customers pay business rates?

Normally, no. The storage facility is assessed as a whole and the operator is the rateable occupier, so the rates bill lands on the business, not on its customers. A customer holding a unit under a storage licence has permission to store goods rather than exclusive occupation of premises, and does not usually receive any separate rates assessment for the unit — their contribution to the site's rates arrives the same way as their contribution to its lighting: inside the licence fee.

That holds for business customers storing stock just as it does for households. Anything beyond a standard licence arrangement — exclusive use of a whole compound or a defined parcel of the site, for instance — can change the analysis, and is a question to put to the VOA rather than to guess.

Challenging the valuation

If the rateable value looks wrong — wrong floor areas, a wrong site description, or a figure out of line with comparable storage sites nearby — England runs a formal three-stage process, generally known as Check, Challenge, Appeal, through your online business rates valuation account with the VOA. Check confirms or corrects the facts the valuation rests on. Challenge argues the valuation itself, with your evidence. Appeal takes an unresolved challenge to the independent Valuation Tribunal.

Three practical rules. Start with the facts — errors in site area and description are the commonest and cleanest wins. Keep paying the billed amount while the process runs; a successful outcome is refunded. And be sceptical of cold-calling "rates specialists" promising guaranteed reductions for a percentage — the process is free to use directly, and the facts-first stage needs no specialist at all.

Budgeting for rates from day one

Rates belong in the fixed-cost line of your business plan, next to the cost of the site itself — and they share its most dangerous property: complete indifference to your occupancy. That makes them a fill-up-phase burden precisely when revenue is thinnest, and it makes "we'll see what the bill says" a plan to be surprised.

The practical sequence: look up comparable storage sites on the VOA's find-a-valuation service before committing to a site; pencil that estimate × 43.2p into the plan; work out the small business rate relief position honestly rather than optimistically; and never write zero against the line unless the relief genuinely puts it there. Where rates sit among the other numbers a first site has to carry — build costs, fit-out, professional fees, management software — is covered in our guide to the cost of building self storage.

Rates are one line in a bigger cost picture. Cost to build self storage covers the capital side, is self storage profitable? puts rates into a full P&L, and the UK self storage industry statistics give the revenue benchmarks to weigh them against.
