Business rates on industrial property explained

Business rates are the tax on the occupation of non-domestic property, and for an industrial occupier they are one of the largest fixed costs after rent itself. For an investor they are a void cost on empty space and a factor in occupier demand, because a high rates bill suppresses the rent a tenant can afford to pay. Understanding how rates are calculated, what reliefs exist and how empty property is treated is therefore part of reading the real economics of an industrial unit, not just its headline rent.

This guide explains what business rates are, how they are calculated from the rateable value and the multiplier, the main reliefs including small business rate relief, how empty property rates work, and how the rates position feeds into value and finance. We arrange commercial mortgages and finance on industrial property as a broker and introducer, not a lender, and we are not rating surveyors or tax advisers. For a valuation, an appeal or a relief application, use a qualified rating surveyor and the Valuation Office Agency; everything here is general information.

What are business rates and how are they calculated?

Business rates are charged on most non-domestic properties, including industrial units, warehouses, shops and offices. The bill is calculated by taking the property's rateable value and multiplying it by the business rates multiplier, sometimes called the poundage, set by central government and updated each year. So a unit with a rateable value of £40,000 and a multiplier of, illustratively, around 50 pence in the pound would face a gross rates bill of roughly £20,000 a year before any relief. The actual multiplier changes annually and differs for smaller and larger properties, so always check the current figure.

The rateable value is the key variable, and it is not the rent you pay. It is the Valuation Office Agency's professional estimate of the property's annual rent on the open market at a fixed valuation date, on standard assumptions about repair and terms. Because it is tied to a valuation date and updated only at periodic revaluations, the rateable value can drift away from current market rents between revaluations, which is part of why rateable values are so frequently challenged.

The building blocks of a business rates bill

Element	What it is	Who sets it
Rateable value	Estimated annual open market rent at the valuation date	Valuation Office Agency
Multiplier	Pence in the pound applied to rateable value	Central government, annually
Reliefs	Reductions such as small business rate relief	Set by government, applied by the council
Net bill	Rateable value times multiplier, less reliefs	Billed by the local council

What reliefs reduce business rates on industrial property?

Several reliefs can reduce or remove a business rates bill. The most widely relevant is small business rate relief, which can substantially reduce, or in some cases entirely remove, the bill for properties with a rateable value below set thresholds, with tapering between them, where the business occupies only one main property. For many smaller industrial occupiers in starter units and workshops, small business rate relief is the difference between a manageable cost and a punishing one, and it is one reason demand for small units is so deep.

Other reliefs apply in specific circumstances: rural rate relief, charitable relief for qualifying organisations, transitional relief that phases in large changes at revaluation, and discretionary reliefs councils can grant. The detail and the thresholds change, and they differ between England, Scotland and Wales, so the only reliable approach is to check the current rules for the jurisdiction and the specific property rather than rely on remembered figures.

Do you pay business rates on empty industrial property?

Yes, after an initial relief period. Empty non-domestic property generally attracts an initial period of relief from rates, after which full empty property rates usually become payable, with industrial property and warehouses historically receiving a longer initial empty period than other commercial types. The exact periods and the rules have been changed over time and differ by property type, so confirm the current position, but the principle holds: a vacant unit is not a cost-free asset, because rates fall due once the relief period ends.

This is why void costs are larger than many first-time investors expect. An empty industrial unit carries not only lost rent but also, once the relief period expires, business rates, plus insurance, security and the service charge on common parts that the absent tenant would otherwise have funded. A realistic appraisal of an industrial investment, particularly a multi-let estate with some vacancy, has to carry the full void cost, not just the rent forgone. Our guide to industrial property yields covers how vacant units held in the figures affect a quoted yield.

A vacant industrial unit is not a cost-free asset: once the empty-rates relief period ends, rates fall due alongside insurance, security and the service charge.

Empty rates also shape behaviour. They create a real incentive to let or sell vacant space quickly, and they are part of why owners invest in refurbishment to make tired units lettable rather than leaving them empty to accrue cost. For an investor weighing a part-vacant estate, the empty rates position on the void units is a number to model explicitly, not an afterthought.

How do business rates affect value and finance?

Business rates affect industrial value indirectly but powerfully, through the rent a tenant can afford. An occupier looks at total occupancy cost, rent plus rates plus service charge plus utilities, not at rent in isolation. Where rates are high relative to rent, they cap what a tenant will pay in rent, which feeds straight into the rental value the property can achieve and therefore its capital value. Two physically similar units in different rating positions can support different rents for that reason alone.

For lenders, rates are part of the picture in two ways. On owner-occupied lending, the rates bill is one of the fixed costs that shapes the business's affordability and therefore the loan it can service. On investment lending, the empty rates liability on any vacant space is a void cost the lender will factor into a stressed view of net income, particularly on multi-let estates where some vacancy is normal. A clean, fully let estate with modest rates relative to rent presents a simpler income story than a part-vacant one carrying empty rates.

The practical point for a buyer is to treat rates as part of due diligence, alongside the lease and the planning position. Check the rateable value, understand the reliefs the current or likely occupiers qualify for, and model the empty rates on any vacant space. We see these figures feed into lender appetite on the multi-let industrial estates we arrange finance against, and our commercial mortgage page sets out how investment debt is built.
