How industrial property is valued

Industrial property valuation is the process of estimating what an industrial building would sell for, expressed through two connected numbers: the rent the space would achieve per square foot, and the yield a buyer would pay for that income. Almost everything else in an industrial valuation, the comparables, the adjustments, the assumptions about vacancy and condition, exists to sharpen one of those two figures. That makes industrial simpler in structure than many asset classes, but the detail still decides whether a valuation survives a lender's scrutiny or falls short of the agreed price.

This guide explains how the method works in practice across the size range, from small units to investment-grade distribution and logistics warehouses: rental comparables and pounds per sq ft, yields and capitalisation, the difference between ERV and passing rent, why vacant possession value and investment value diverge, how big-box investments are priced on covenant strength and unexpired lease term, what lenders actually instruct valuers to do under the RICS Red Book, and the wrinkles peculiar to multi-let estates. We arrange finance against these valuations as a broker and introducer. We are not valuers or a lender, and nothing here is financial, legal or tax advice.

How do rental comparables set industrial value?

Every industrial valuation starts with rent, because industrial buildings are commodities priced by the square foot. The valuer assembles recent lettings of comparable units nearby, adjusts for differences, and lands on a market rent for the subject building. The national frame is wide and varies by size: the UK average prime rent was £12.55 per sq ft in 2025 (Savills), within which prime big-box distribution space ran at £11.90 per sq ft and prime mid-box and multi-let space at £15.55 per sq ft (Colliers, H2 2025), and multi-let rents split regionally at £16.82 per sq ft across London and the South East and £8.40 per sq ft across the rest of the UK at Q3 2024 (Gerald Eve Multi-Let, Winter bulletin 2024). Within any one town the spread is narrower but still real, and three or four genuinely comparable lettings within a few miles outweigh any national figure.

The adjustments are where judgement lives. Size matters, because a 2,000 sq ft small warehouse typically lets at a higher rate per sq ft than a 20,000 sq ft unit on the same estate, since more occupiers can afford it. Specification matters: eaves height, loading, yard depth, power supply, office content and EPC rating each move the rate. Location within the town matters as much as the town itself, with estate quality and road access priced street by street. A valuer who cannot find close comparables widens the search and adjusts harder, and the confidence of the final figure falls accordingly, which is something lenders notice.

The evidence itself is more findable than buyers assume. Letting and sale listings on the portals show asking terms, and expired listings show what the market absorbed. Local industrial agents will usually share recent achieved rents on their own estates when asked directly, because today's enquirer is tomorrow's client. The EPC register confirms floor areas, and Land Registry sold-price data anchors the capital side. An afternoon spent building a small comparables table, unit, size, rent or price, date and source, puts a buyer or owner on something close to equal footing with the valuer who will eventually report on the same building.

How do yields turn rent into capital value?

A yield is the annual rent expressed as a percentage of the price, and capitalisation is the act of dividing the rent by that yield to produce a capital value. The two move inversely: the lower the yield a buyer accepts, the more they are paying for each pound of rent. The sourced benchmarks span the size range: UK prime distribution and logistics yields stood at 5.00 percent in January 2026 (Knight Frank, UK Logistics Market Dashboard), the prime multi-let equivalent yield was 5.45 percent at Q3 2024 (Gerald Eve Multi-Let, Winter bulletin 2024), and the all-industrial equivalent yield across the whole market was 6.21 percent in February 2026 (Knight Frank / MSCI). Ordinary secondary units price at softer yields than prime, deal by deal.

That single example is why the chosen yield, not the rent, is usually the figure worth arguing over in a valuation. Capitalised at 6.5 percent the unit is worth about £1.38 million; at 7.5 percent about £1.2 million.

What sets the yield is risk and the depth of demand. On a big-box distribution warehouse let to a single occupier, two factors dominate the valuer's yield choice above all others: the covenant strength of the tenant, meaning how financially secure the business paying the rent is, and the unexpired lease term, meaning how many years of contracted income remain before a break or expiry. A long lease to a strong national covenant prices at a keen yield near the prime distribution benchmark, while a short unexpired term or a weaker covenant pushes the yield out sharply, because the buyer is pricing the risk of an empty shed. More broadly, yields tighten with location quality, tenant strength, lease length and the breadth of the buyer pool, and soften with risk in any of those. Yields also move with the wider cost of money, since property competes with other income-producing assets for capital, which is why valuations can shift across a whole market without a single building changing. The evidence for the chosen yield comes from actual sales of comparable investments, not from sentiment, and a good valuation report names those transactions.

What is the difference between ERV and passing rent?

ERV, the estimated rental value, is the rent a property would achieve if let today at market levels; passing rent is the rent actually being paid under the current lease. The two diverge constantly, because leases fix rents for years while markets move. After the strong industrial rental growth of recent years, many units are reversionary, with passing rent below ERV, and the gap is called the reversion: embedded future income growth that crystallises at rent review, lease renewal or re-letting. Forecast multi-let rental growth of 4.6 percent a year on average over 2024 to 2028 (Gerald Eve Multi-Let, Winter bulletin 2024) suggests reversions will keep being created as fast as they are captured.

Valuers handle the gap explicitly. A reversionary investment is valued on the passing rent until the next lease event and on ERV thereafter, so the value reflects both what the asset earns now and what it should earn soon. An over-rented unit, where passing rent exceeds ERV, is marked the other way, with the excess income treated as less secure. For buyers, the practical reading is simple: two units with identical passing rents are not identical investments if one has a review in eighteen months and rents nearby have moved. The reversion is often where the real value in an industrial purchase sits, and it is also what a good agent will make you pay for.

Testing an ERV claim is straightforward in principle: it should be evidenced by recent lettings of comparable space, not by asking rents alone and not by the seller's optimism. When a sales pack quotes an ERV well ahead of anything actually achieved nearby, the gap is a negotiating point, because the lender's valuer will apply the same scepticism. Equally, a genuinely reversionary unit with a rent review eighteen months out and hard local evidence behind the uplift deserves to be priced as such. The discipline cuts both ways, and the tenancy schedule plus three or four named comparables settles most arguments.

Why do vacant possession value and investment value differ?

Vacant possession value is what a property is worth empty, available for an occupier to buy and use; investment value is what it is worth with its tenancies and income in place. For most commercial property the investment value of a well-let building comfortably exceeds its empty value. Small industrial units are the great exception: owner-occupier demand for units businesses can buy and occupy is so deep, and the stock so scarce, that vacant units regularly sell for more than the same unit would fetch as a tenanted investment. Strong businesses will outbid investors for control of their own premises.

This crossover has practical consequences. Sellers of smaller units increasingly wait for leases to end and sell empty rather than selling the investment. Valuers asked for both bases can legitimately report a higher figure for the empty building than for the let one, which surprises owners used to residential logic. And the buyer's identity changes the right price: an owner-occupier comparing the mortgage cost against the rent they would otherwise pay can justify a figure a yield-driven investor cannot, especially while rents keep rising. Knowing which buyer you are, and which basis the asking price reflects, is half of negotiating an industrial purchase well.

Lenders read the two numbers as a pair. On an investment loan, the investment value sizes the facility, but the vacant possession figure tells the credit team what their security is worth in the downside scenario where the tenant leaves and the unit must be sold empty. On small units, where the vacant figure is the higher one, that downside is unusually well protected, which is part of why lender appetite for ordinary small industrial stock is as deep as it is. On big single-let boxes the gap runs the other way, and the credit questions get harder accordingly.

What does a lender instruct the valuer to do?

When finance is involved, the valuation is the lender's document, not the buyer's. The lender instructs a valuer from its panel to report under the RICS Valuation Global Standards, the Red Book, which governs independence, inspection, evidence and the bases of value. A typical instruction asks for market value as the headline figure, often market rent alongside it, a reinstatement cost for insurance, and commentary on saleability, condition, environmental risk and EPC compliance. For tenanted assets the lender usually wants market value both as an investment and with vacant possession, precisely because the downside scenario, an empty building, is the one its security exists for.

The borrower pays the fee but the valuer owes the duty of care to the lender, and the loan is sized from the reported figure, not the agreed price. Where the valuation lands below the price, the loan shrinks and the buyer funds the gap, renegotiates or walks away. In our experience arranging commercial mortgages on industrial property, valuation shortfalls usually trace back to thin comparable evidence behind an ambitious price, and the best protection is assembling the rental and sales evidence before offering rather than hoping the valuer finds it.

Borrowers are not passengers in this process. You can and should send the valuer the evidence that supports the price: the comparable lettings and sales you priced from, the planning position, the EPC, any recent works and, on investments, a clean tenancy schedule. Valuers are required to reach their own view, but they work from the evidence available, and a well-organised pack both speeds the inspection and reduces the odds of a conservative figure built on missing information. We prepare that pack with clients as part of packaging the loan, because a valuation that lands where the deal needs it is mostly the product of preparation.

How are multi-let industrial estates valued?

A multi-let industrial estate is valued as a single income-producing asset, but its income is a mosaic: a dozen or more leases with different rents, lengths, break clauses and tenant strengths, plus whatever stands empty. The valuer works from the tenancy schedule, comparing each passing rent with ERV, weighting the unexpired lease terms, and deducting the costs a single-let building does not carry, including void holding costs, letting fees and estate management. Vacancy is treated as a feature to be priced rather than a flaw: the 9.4 percent vacancy across institutionally held UK industrial property at December 2025 (MSCI UK Quarterly Property Index, Q4 2025) reflects an asset class where some churn is structural.

The wrinkle that surprises first-time estate buyers is that granularity is rewarded, not punished. Because no single tenant dominates the income, the failure of any one of them is survivable, and because small units relet quickly in an undersupplied market, voids are short. Institutional buyers pay up for exactly this profile: Sirius Real Estate's four UK acquisitions in its FY2026 year, led by the £101 million Hartlebury Trading Estate purchase, averaged a 6.7 percent gross yield with 84.2 percent occupancy at purchase (Sirius Real Estate FY2026 annual results), buying income with vacancy left to work on. For lenders, estate valuations get an extra layer of interrogation, with credit teams testing the schedule for concentration, imminent expiries and the gap between passing rent and ERV, and sizing the loan against income that survives a tenant or two leaving.

How can you estimate an industrial unit's value yourself?

A defensible desktop estimate takes an afternoon. First, establish the floor area in sq ft from the listing, the EPC record or a measurement. Second, find the rent: gather asking and achieved rents on comparable units within a few miles from the portals and local agents, adjust for size and specification, and settle on a rate per sq ft you could defend out loud. Third, choose a yield from evidence of what comparable units and investments have actually sold at locally, sense-checked against the sourced benchmarks, prime distribution and logistics at 5.00 percent (Knight Frank, January 2026), prime multi-let at 5.45 percent (Gerald Eve Multi-Let, Winter bulletin 2024) and an all-industrial equivalent of 6.21 percent (Knight Frank / MSCI, February 2026), with an appropriate margin for secondary stock, since ordinary units in ordinary towns transact well wide of prime. Multiply area by rent, divide by the yield, and you have an investment-basis estimate; then compare it against straight sales of similar units, which captures the owner-occupier premium where one exists.

Treat the result as a negotiating tool, not a number to borrow against. Online estimates and calculators cannot see the roof, the title or the tenancy schedule, and a formal figure for purchase or lending purposes needs a RICS Registered Valuer reporting under the Red Book. The desktop exercise still earns its keep twice over: it stops you anchoring on an asking price, and it predicts roughly where the lender's valuation will land, which lets the funding be sized realistically from the start. Our commercial mortgage calculator turns that estimated value into indicative loan sizes and payments in a few minutes.
