Capital allowances on commerical property
Capital allowances are a valuable form of tax relief if you own a commercial property. They can bring considerable cash flow benefits for any eligible capital expenditure, such as plant and equipment.
When making a capital allowances claim there are different types of relief available to your business depending on the asset class you have invested in.

Plant and machinery capital allowances
One type of expenditure that qualifies for capital allowances relief is plant and machinery. This is expenditure incurred on items that are used in your business.
What can be claimed?
There are a wide range of assets that businesses can claim deductions on as part of plant and machinery capital allowances. These include cars, fixtures, and parts of a building considered integral. You can also claim for the cost of altering a building to accommodate plant and machinery, as well as demolishing it.
What are capital allowances integral features?

Integral features for the purposes of capital allowances claims fall into six categories:
- lifts, escalators and moving walkways;
- space and water heating systems;
- air-conditioning and air cooling systems;
- hot and cold water systems (but not toilet and kitchen facilities);
- electrical systems, including lighting systems; and
- external solar shading.
What are capital allowances fixtures?
When you’re assessing what might qualify as a capital allowance fixture, consider what is attached to the building itself. Examples might include:
- fitted kitchens and bathrooms; and
- fire alarm and CCTV systems.
What can’t be claimed?
As with other forms of capital allowances, there are inevitably exclusions. It’s not possible to claim plant and machinery allowances on items that have been leased; items used exclusively for business entertainment; structures such as roads; or buildings, including doors, shutters and gates.
Keep in mind that you may be eligible to claim for structures and buildings allowances. If you require guidance on what falls into each category, contact a reputable adviser such as ForrestBrown, who can advise you on eligibility.
Structures and buildings allowances
Structures and buildings allowances (SBAs) are a type of expenditure that qualifies for capital allowances relief. It can be claimed if the taxpayer has a relevant interest in the building or structure. A relevant interest is the interest in the building or structure held by the person who incurred the expenditure. That person will likely have bought, built or leased the property.
Who can claim?
Those that are eligible to claim fall into three broad categories and reflect a range of different interests in/relationships with the property.
Investors in projects involving new builds or enhancements of existing property – may be eligible to claim SBAs on related expenditure if construction contracts were signed on or after 29 October 2018. The SBAs potentially claimable are on construction costs including design fees; preparation of the construction site; construction works; renovations and conversions.
Lessors are entitled to claim SBAs if the lease that has been granted is less than 35 years. If the lease is for 35 years or more and the lessee pays a substantial premium, the right to claim SBAs passes to the lessee.
If you purchase a property, your claim eligibility will vary depending on who you purchased the property from, whether it’s been sold more than once and whether it is used or unused.
What can’t be claimed?
There are a number of expenses associated with buildings that can’t be claimed as SBA, for example, planning permission, legal expenses and land costs.
You also need to be mindful of any other allowances that you’ve claimed and ensure that the item you’re claiming for hasn’t already been used to claim another allowance. Be aware that you can’t claim on anything for which you’ve received a grant or contribution.
If in any doubt as to what qualifies and what doesn’t, seek the advice of an expert adviser. At ForrestBrown, we can review your purchase or project and give you clear advice on the parameters of your claim, including applicable rates and allowance periods.
