Commercial property transactions are complex enough that most buyers and sellers focus on the headline numbers: the price, the yield, the lease terms, the financing structure. The tax position, and specifically the capital allowances embedded in the property, frequently gets either overlooked entirely or addressed too late to capture the full benefit. This is one of the most consistently expensive mistakes in commercial property investment.
Capital Allowances Explained
When a business purchases a commercial property, part of what they are acquiring is not just bricks and walls but a collection of plant and machinery embedded within the building. Heating and ventilation systems. Electrical installations. Fitted equipment. Security systems. Lifts. Fire suppression infrastructure. Under UK tax law, expenditure on qualifying plant and machinery attracts capital allowances, which are a form of tax relief that reduces taxable profit.
The challenge is that these allowances are not automatically applied. They require identification, quantification through a specialist survey, and a formal claim. Without this process, the relief simply does not happen, regardless of whether the qualifying expenditure exists within the property.
Professional Commercial Property Guidance from Property Capital Allowance provides exactly this service for buyers and sellers navigating commercial property transactions, ensuring that the embedded tax value of a property is identified and appropriately handled before and at the point of sale.
The Transaction Timing Problem
Capital allowances in commercial property transactions are governed by specific rules under UK tax legislation. When a property changes hands, the buyer and seller are required to make a Section 198 election to agree on how the historic allowances are split between them. This election must be made within two years of the transaction completing.
If no election is made, or if it is made on unfavourable terms because neither party took specialist advice, significant allowance value can be lost permanently. The two-year window sounds generous, but given that tax affairs in a business context tend to move slowly and this is not an area most accountants specialise in, the deadline passes without proper action more often than it should.
What a Capital Allowance Survey Involves
A specialist capital allowance survey involves a qualified surveyor reviewing the property and its embedded fixtures and plant to identify and value qualifying items. This is distinct from a standard structural survey and requires expertise specific to capital allowances rather than general property condition.
The output is a formal report that quantifies the value of qualifying expenditure and supports a tax claim. For commercial properties of significant value, particularly those with substantial M and E installations, the relief can run to hundreds of thousands of pounds.
Why Both Buyers and Sellers Benefit From Specialist Advice
From a seller’s perspective, understanding what capital allowances exist within a property is relevant to how the transaction is structured. A seller who has been claiming allowances on embedded plant needs to understand the implications of transferring those allowances and the tax consequences of different structuring approaches.
From a buyer’s perspective, identifying available allowances before exchange means they can be factored into the purchase rationale and claimed efficiently after completion. Without pre-transaction advice, buyers regularly acquire properties with significant embedded tax value they never access.
The combination of technical tax knowledge and property expertise required to navigate this properly is the reason specialist advisory input makes commercial sense for most transactions above a threshold value.
FAQ
What is a Section 198 election in commercial property? A Section 198 election is a formal agreement between buyer and seller that fixes the value at which historic capital allowances are transferred in a commercial property sale. It must be made within two years of completion and affects how much tax relief the buyer can claim.
How much can capital allowances be worth in a commercial property? The value depends on the property’s specification and the type of embedded plant and machinery. In commercial buildings with significant M and E installations, qualifying expenditure can represent 20 to 40 percent or more of the property’s total value for allowance purposes.
Do residential properties qualify for the same capital allowances? Capital allowances for plant and machinery are generally only available on commercial property. Furnished holiday lets have specific rules. Standard residential buy-to-let properties do not qualify for the same allowances.
When is the best time to get capital allowance advice in a transaction? Before exchange of contracts. This is when structuring decisions can still be made and when the election terms can be negotiated as part of the wider transaction.
Does every commercial property have claimable capital allowances? Most commercial properties contain some qualifying plant and machinery. The value varies significantly by property type, age, and specification. A specialist survey will establish what is actually present and claimable in any given property.
