What Replaced the ECA Scheme?
Annual Investment Allowance (AIA)
The original Enhanced Capital Allowance (ECA) scheme, which provided 100% first-year relief on energy-saving equipment, ended in April 2020. However, several highly valuable allowances remain available to commercial property owners today.
Provides 100% first-year tax relief on qualifying plant and machinery expenditure up to £1 million per year. For most commercial property purchases, renovations, or fit-outs, AIA remains one of the most powerful tools available.
Full Expensing
Introduced as the successor to the super-deduction, full expensing allows companies to deduct 100% of qualifying main pool expenditure in the year it is incurred, with no upper limit. Available to limited companies on new qualifying plant and machinery.
Structures and Buildings Allowance (SBA)
Provides 3% per year relief on the costs of constructing, renovating, or converting non-residential buildings. Often overlooked by accountants and a key area CARS examines in every review.
Embedded Property Capital Allowances
The most significant opportunity for most commercial property owners. The fixtures and fittings embedded within the fabric of a building, installed by a previous owner or during construction, often carry unclaimed allowances that can be identified through a specialist survey. This is CARS’ area of deepest expertise.
Frequently Asked Questions
Can I still claim enhanced capital allowances on my commercial property?
The original ECA scheme ended in April 2020. However, significant capital allowances remain available on commercial property through the Annual Investment Allowance, Full Expensing, Structures and Buildings Allowance, and embedded property capital allowances. CARS can identify which allowances apply to your specific property and circumstances.
How far back can I claim capital allowances on a commercial property?
In many cases, there is no time restriction on claiming embedded capital allowances on commercial properties purchased before April 2014. For properties acquired after April 2014, a two-year window from completion typically applies, though exceptions exist. CARS will assess your specific situation during a free initial review.
Does my accountant not already claim these allowances?
Most accountants claim standard capital allowances but do not carry out the specialist property survey required to identify embedded fixtures and fittings. CARS operates as a specialist alongside your existing accountant, uncovering allowances that would otherwise remain unclaimed.
What types of properties qualify?
Any commercial property used for a qualifying business activity can be reviewed. This includes offices, factories, retail premises, care homes, hotels, restaurants, and commercial investment properties.
Is there a cost to the initial review?
CARS offers a complimentary initial review to assess the potential value of your claim before any commitment is made.
