Landed estates and rural businesses: The distinction between revenue and capital expenditure

Against a backdrop of rising compliance obligations, ageing building stock, sustainability-driven investment and significant reform of the residential lettings market through the Renters’ Rights Act 2025, estate owners are increasingly required to undertake works that enhance, modernise and maintain their properties. 

The tax treatment of those costs can have a material impact on cash flow and profitability. While expenditure on repairs is generally deductible against rental income, capital expenditure is usually relieved only through capital allowances or on a future disposal. As estates seek to balance regulatory compliance, tenant expectations and long-term asset stewardship, understanding where maintenance ends and capital improvement begins remains one of the most important and frequently challenged areas of property taxation.

Whether an item of expenditure is classified as a capital or revenue expense first depends on the “entirety principle”. This principle centres on the importance of identifying the asset on which work is being carried out. This is because the cost of repairing a worn or dilapidated asset is normally considered revenue and therefore allowable, but the cost of replacing the whole or entirety of an asset is capital and therefore not allowable. 

An example of this principle would be replacing the roof on a property. The entirety for these purposes is the whole building and therefore by replacing only the roof, you are not replacing the entirety of the asset. As such, the roof replacement works would be considered a revenue expense.

It is largely a question of fact as to whether works to a specific property result in an improvement to that property.

However, where a property is improved simply by virtue of bringing that property up to modern standards, using up to date materials and technology, this would still be considered a revenue expense. 

Examples of this would be replacing single glazed windows with double glazed windows or replacing wooden beams with steel girders. While there is an apparent element of improvement here, because the windows and beams are being replaced with similar but more modern materials, this would still be considered a revenue expense. 

Where a significant improvement arises due to these changes, however, then there would be a capital element to the works. For example, if as part of a property refurbishment a room is added, the element of works relating to that new room would be considered capital.

It is common for works to a single property to include both capital and revenue works. In this situation, HMRC accepts that expenditure can be apportioned on a reasonable basis. This could be based on a contractor’s schedule of works, for example.

As mentioned above, tax relief for capital expenditure may still be available against profits in the form of capital allowances. Broadly speaking, capital allowances are not available in respect of works undertaken to residential property, but they are available on commercial property and assets used within a trade. 

The level of capital allowances available will depend on the nature of the relevant capital expense and the categories are set out below. 

Plant and machinery will be apparatus used for carrying on the business, which can include costs incurred to alter a building to install plant and machinery equipment. 

For a trading business, this could include tractors, drills and rollers used within a farming business. It could also include new items in the farm office such as computers, desks and chairs. 

The annual investment allowance (AIA) is a 100% relief for qualifying plant and machinery expenditure, although it is worth noting that trusts are not entitled to claim AIA and neither are partnerships that have a trust or corporate partner. Instead, a writing down allowance (WDA) of 18% would be available on qualifying plant and machinery costs.

Integral features are specific plant and machinery that are classified as integral to a building. Examples include an electrical system (including a lighting system), cold water system, water heating system, any floors or ceiling comprised in such a system, lifts, escalators and external solar shading. 

There is a particular quirk with integral features, whereby if repairs are carried out to an integral feature and that expenditure amounts to more than 50% of the replacement costs of that item, it will not be regarded as a repair. Instead, it will be treated as capital expenditure and capital allowances may be claimed if relevant. 

Similarly to plant and machinery, integral feature expenditure is pooled, and capital allowances claimed as a 6% WDA.

Some costs are treated as part of the building, and therefore standard capital allowances are not available. These assets would include walls, floors, ceilings, doors, gates, shutters, windows and stairs. An example could be new stairs or a new doorway being built on renovation of a commercial building. This would be a capital cost and structural in nature.  

If these costs relate to a non-residential property, the costs will qualify for the structures and buildings allowance (SBA), which allows the business to claim 3% of the cost every year for 33 years and one-third. 

The distinction between capital and revenue expenditure is complex and highly fact specific. Reviewing projects at an early stage can help ensure costs are treated correctly, and that all available tax reliefs are identified.

We recommend preparing a schedule of works before a project begins, allowing expenditure to be reviewed as it is incurred and helping to maximise available tax deductions, reliefs and allowances. 

If you are planning refurbishment works, estate improvements or property compliance projects, our team would be happy to discuss how these costs should be treated for tax purposes.
