Search for a self-storage business to buy and you will find plenty of inventory. The listing marketplaces are full of stores and removals-and-storage companies with an asking price, a turnover figure and a photograph. What none of them tell you is the only thing that determines whether you can actually buy it: how a lender will value the earnings, how much debt those earnings will carry, and what is left for you to fund in cash.
That is the gap this guide fills. We arrange acquisition financing, and specifically self-storage acquisition finance across the United Kingdom, and the deals we see most often sit in South East England, where the density of stores, the strength of catchments and the weight of institutional ownership make the buy side genuinely competitive. Below we set out how a self-storage business is valued for lending, why asset and share purchases fund differently, how much you can borrow, and what the equity cheque really looks like once fees are in. All figures are indicative market commentary, not quotes or offers.
How a self-storage business is valued for lending
A trading self-storage business is valued primarily as a multiple of EBITDA, the earnings the store generates after operating costs, supported by a discounted cash flow of its net operating income. Valuing a self-storage facility is a different exercise from valuing a let commercial building, and it is worth understanding before you make an offer.
The valuer looks at four things. Occupancy rates against the maximum lettable area, because empty storage space is capacity you have paid for and are not earning on. The net achieved rate per square foot, which is what customers actually pay after discounts and promotions, not the rate on the price list. The quality and location of the site, which drives both the catchment and the ceiling on rate. And the scope to push pricing, which is where a buyer’s upside usually sits.
Two national benchmarks give you the reference points. Average annual revenue across the UK estate runs at £27.40 per sq ft excluding VAT on the 2026 definition, and mature stores average 79.6% occupancy against 74.5% across all stores (SSA UK / Cushman & Wakefield Annual Industry Report, 2026). If the store you are buying is materially below those on either measure, that is either your value-add case or your warning sign, and the diligence has to establish which.
The critical consequence is that the trading valuation usually sits well above the vacant possession value of the building. On the evidence from listed operators, trading stores range from £185 per sq ft for smaller-format regional stock up to £458 per sq ft for prime London and South East weighted portfolios, going-concern basis (Big Yellow FY2026 results, JLL-valued). You are buying a business inside a building, and you are borrowing against the business.
Asset purchase or share purchase, and why it changes the debt
Almost every self-storage acquisition is structured one of two ways, and the choice reaches further into the funding than most buyers expect.
An asset purchase buys the property and the trading assets, leaving the seller’s company behind with its history. It is cleaner for a lender because the liabilities stay with the vendor, so diligence is narrower and appetite is generally broader. It is the default for a first-time buyer.
A share purchase buys the company that owns the store, which means you inherit everything: the trading history, the contracts, the employment position, the tax position and any liability sitting in the balance sheet. Sellers often prefer it for their own tax reasons, and it can be the only way a deal gets done. Lenders will fund it, but they will want deeper diligence, more comprehensive warranties and indemnities, and sometimes a retention. Expect the process to take longer.
Neither is universally right. What matters is that you decide early, because switching structure halfway through re-opens the credit paper and can cost you weeks you do not have. This is a question for your solicitor and your accountant as much as your broker, and it should be settled before heads of terms are signed.
How much a buyer can borrow against the trading valuation
Most lenders advance up to around 60 to 70% loan to value against the trading valuation of a stabilised self-storage facility, on loans from around £250,000 to £50m and beyond. Because that valuation reflects the earnings of the business rather than just the building, the debt a strong store supports is often well above what a vacant possession valuation would suggest.
But loan to value is only the first ceiling. The second is debt service cover: the lender sizes the loan so EBITDA covers interest and any capital repayment with headroom to spare. On a stabilised store with a settled trading record, the loan to value ceiling usually binds first. On a store with lumpy earnings, a short trading history, or occupancy still climbing, the cover test binds first and the advance comes in below the headline percentage. Do not budget on the headline.
Rates start from around 6% and move with leverage, the store’s trading record, the strength of the buyer’s covenant and whether the rate is fixed or floating. With Bank of England base rate held at 3.75% since December 2025, term pricing has been comparatively stable through 2026, which makes forward planning on a purchase easier than it has been for several years.
What the equity cheque actually looks like
Here is the worked example we use most often, because it makes the arithmetic concrete.
A buyer is acquiring an established self-storage facility for £3m. The store has 35,000 sq ft of maximum lettable area, occupancy settled in the mid eighties in percentage terms, and EBITDA of £330,000 a year, so the price reflects a multiple of roughly nine times earnings. The lender values the asset on its trading income and offers 65% loan to value, an advance of £1.95m. The buyer funds £1.05m of equity, plus costs.
On an indicative rate in the region of 6.5%, the EBITDA covers the debt service comfortably, so the deal clears both ceilings.
Now add the costs the headline price does not include: an arrangement fee typically at 1 to 2% of the facility, so £19,500 to £39,000; a valuation, which on a trading store is a going-concern valuation and costs accordingly; legal fees on both sides; stamp duty land tax on an asset purchase; and diligence on the trading records. Fit-out costs on an older store can add to that too, so budget meaningfully above the £1.05m, and hold a contingency, because the one thing that reliably moves in an acquisition is the timetable.
Buying in the Home Counties and the wider South East
South East England is the most competitive buy-side market in the country, and there are good reasons to be in it and good reasons to be careful.
The case for it is straightforward. The South East and London carry the strongest catchments and the highest achieved rates in the UK, which is why the listed operators are so heavily weighted there: 75% of Big Yellow’s same-store portfolio sits in London and the commuter towns, and Safestore holds 78 of its 139 UK stores in London and the South East (Big Yellow FY2026 and Safestore FY2025 results). Consistent demand across these catchments is why institutional buyers agree: the QuadReal and Clear Sky joint venture that acquired a 27-asset, 1.2m sq ft UK portfolio in March 2026 was South East concentrated (QuadReal press release, March 2026).
The case for caution is the same fact from the other side. You are bidding against self storage operators with cheaper capital and against real estate institutions writing portfolio cheques. Our planning data shows steady development activity through South East authorities including Adur and Worthing, Reigate and Banstead, and Windsor and Maidenhead (Construction Capital planning data, August 2026), so new supply is coming into some of these catchments. A store bought at a full multiple in a catchment about to receive a competing purpose-built facility is a very different proposition from the one in the information memorandum.
The practical point for a buyer: value the store on what it earns today with a realistic view of what a new entrant would do to your rate, not on a growth case that assumes no competition arrives.
Buying as an operator or buying as an investment
The same store funds differently depending on who is buying it, and it is worth being clear which you are before you approach the market.
Operators buy to run. Lenders assess the operating capability alongside the real estate: the management platform, the pricing policy, the staffing model, the marketing. Established self storage operators with a trading record get the keenest terms available, because the lender is underwriting a business it can already see working. Loans here run the full range, from around £250,000 to £50m and beyond.
Investors buy for income and capital growth, with management provided by a third party or retained from the vendor. Here the credit question becomes what happens if that management arrangement ends. A store with a strong third-party contract, clean reporting and a documented handover is a straightforward real estate investment. A store where the operating knowledge sits entirely with the person selling it is a much harder credit paper, whatever the trading figures say, and the leverage will reflect it.
The published evidence on returns is worth reading before you commit either way. Prime self storage yields sat at 5.0% at Q4 2025 with secondary at 6% and above (Savills, European Self Storage Spotlight, Q4 2025), and Big Yellow reported a weighted average exit cap rate of 5.2% across its portfolio at September 2025 with a year-one net initial NOI yield of 4.9% (Big Yellow H1 FY2026 valuation, CBRE-valued). Those are institutional-quality assets. A single regional store bought at a full multiple will not price like one, and the annual report of any listed operator is a more useful benchmark than a broker’s projection.
Two more investment considerations that catch buyers. Self storage revenue attracts VAT in most cases, which is a cashflow and pricing question rather than a barrier, but it needs to be in the model. And the operating leverage cuts both ways: because storage operating costs are low relative to revenue, occupancy gains fall through to earnings quickly, and so do occupancy losses.
The diligence a lender will want before it commits
Expect to produce, at minimum: three years of trading accounts and management accounts to date; a unit-level occupancy and rate report showing how the achieved rate has moved, not just where it sits; the licence agreement terms and any long-standing customer concentrations; the site’s planning position and use class; a schedule of the fit-out and its condition, because racking and partitioning have a real replacement cost; and evidence of the operating platform, whether that is management software, staffing or a third-party management contract.
Two items catch buyers out. The first is the difference between headline rate and achieved rate: a store running heavy introductory discounting looks better on the price list than in the cash. The second is capital expenditure that has been deferred. A store that has not reinvested in its fit-out for a decade has a bill coming, and a lender that spots it will size the loan down accordingly.
If the store you are buying is not yet stabilised, or the vendor will not wait for a term lender’s credit process, the route is usually a bridge first and a refinance onto term debt later. We cover that structure in the bridging guide in this series.
Frequently asked questions
How much does it cost to buy a self storage business in the UK? It depends entirely on the earnings rather than the floor area. Trading stores have changed hands on the listed evidence at anywhere from £185 per sq ft for smaller-format regional stock to £458 per sq ft for prime London and South East weighted portfolios, going-concern basis (Big Yellow FY2026 results, JLL-valued). In practice a single established store commonly sits in the low single-digit millions, priced off a multiple of EBITDA. Buying an established store costs more than building one, but it comes with earnings from day one rather than a 3 to 5 year lease-up.
How is a self-storage business valued? Primarily as a multiple of EBITDA, supported by a discounted cash flow of net operating income. The valuer tests occupancy against maximum lettable area, the net achieved rate per sq ft, site quality and location, and the scope to push pricing. That going-concern figure is normally well above the vacant possession value of the building, which is why the debt available is higher than a bricks-and-mortar valuation would imply.
Can I buy a self-storage business with no trading history in the sector? Yes, but expect the terms to reflect it. Lenders price the operator as well as the asset. A first-time buyer with no storage operating experience will usually see lower leverage, tighter covenants and sometimes a requirement for a third-party management contract or an experienced operations hire. The most common way through is to buy a stabilised store with a management platform already in place, so the lender is underwriting a functioning business rather than your learning curve.
