If you’re investing in commercial property or managing development projects, there’s a valuable tax relief you might be overlooking: Capital Allowances.

These allowances can significantly reduce your tax bill — but many property owners and developers miss out because they don’t know what qualifies or how to claim correctly.

Here’s a practical overview of what Capital Allowances are, how they apply in the property sector, and how you can benefit.

---

What Are Capital Allowances?

Capital Allowances allow you to claim tax relief on certain capital expenditure — essentially the cost of purchasing or improving assets used in your business.

Instead of deducting the cost all at once (like you would with day-to-day expenses), Capital Allowances let you spread the tax relief over time, reducing your Corporation Tax or Income Tax liability.

Common Qualifying Assets in Property & Construction:

While land and buildings themselves don’t qualify, many of the assets inside or attached to buildings do, especially in commercial property.

Here are some typical qualifying items:

• Heating and air conditioning systems
• Electrical systems
• Fire safety and security systems
• Plumbing and water systems
• Lifts and escalators
• Kitchens and sanitary fittings (in commercial settings)
• Integral features (like lighting or ventilation)

These are known as “plant and machinery” — and they form the basis of most claims.

Key Types of Capital Allowances

1. Annual Investment Allowance (AIA)

You can claim up to £1 million of qualifying expenditure immediately (per business, per year). This is especially useful for developers fitting out new commercial spaces.

2. Writing Down Allowances (WDA)

If your spend exceeds the AIA limit, or if it’s on items that don’t qualify for AIA, you may still claim relief at a set percentage each year (typically 6% or 18%).

3. Structures and Buildings Allowance (SBA)

Introduced in 2019, this gives relief on the cost of constructing or renovating commercial buildings, claimed at 3% per year over 33⅓ years. Land and residential property don’t qualify.

4. Enhanced Capital Allowances (ECA)

These used to apply to energy-efficient items — now phased out — but some green tech still qualifies under separate schemes.

Real-World Example

Let’s say you’ve just refurbished a commercial office space and spent:

• £40,000 on air conditioning
• £25,000 on electricals
• £15,000 on a fire alarm system

All these may qualify for Capital Allowances, potentially allowing you to offset £80,000 against your taxable profits, reducing your Corporation Tax liability by up to £15,200 (based on 19%).

Why You Shouldn’t Leave It to Chance

Capital Allowances are often overlooked, especially when buying or refurbishing properties. HMRC doesn’t prompt you to claim — and if you miss the window, the tax benefit is lost forever.

That’s why it’s critical to:

• Review purchases and developments carefully
• Work with a specialist accountant
• Claim allowances during or immediately after project completion
