Replacement Relief: What Counts as Like-for-Like

Introduction: The Mechanics of Replacement Relief

For UK residential landlords, the landscape of tax relief shifted permanently with the phased introduction of Section 24 of the Finance (No. 2) Act 2015.

By April 2020, the ability to deduct finance costs from rental income was effectively eradicated for most, replaced by a basic-rate tax credit.

Amidst this tightening of the rules, Replacement of Domestic Items Relief (often shortened to Replacement Relief) remains one of the few legitimate deductions available to reduce taxable rental profits.

However, the legislation is deceptively narrow.

Misunderstanding the scope of "like-for-like" can lead to incorrect tax returns, potential HMRC enquiries, and unexpected tax liabilities.

This guide focuses strictly on the practical application of Replacement Relief.

It moves beyond the theory to examine the specific criteria for what constitutes a valid replacement, the definition of "like-for-like" in the eyes of HMRC, and the financial trade-offs involved when upgrading assets.

It is relevant for landlords operating under the standard tax regime; those with properties in a limited company structure can generally claim capital allowances or deduct costs as repairs, but the rules discussed here specifically apply to unincorporated property businesses.

The Core Principle: Replacement vs.

Improvement

To claim Replacement Relief, you must satisfy the fundamental condition that an old item has been replaced by a new one.

This is not a deduction for general maintenance or the purchase of new assets for a property that previously lacked them.

The relief applies when a domestic item is genuinely replaced.

The cost of the new item is deductible from your rental income in the tax year in which the expenditure is incurred, provided the old item is no longer available for use.

The friction arises in the distinction between a "repair" and a "replacement".

If you repair a broken washing machine by replacing a specific component, this is generally treated as a revenue repair expense, deductible against income.

However, if the machine is beyond repair and you purchase a new one, this falls under Replacement Relief.

The distinction matters because while both reduce taxable profit, Replacement Relief has specific rules regarding the disposal of the old asset and the quality of the new one.

The "New to the Property" Trap

A common error involves furnishing a previously unfurnished property.

If you purchase a property and subsequently buy a sofa, a bed, and a dining table, you cannot claim Replacement Relief.

There was no old sofa to replace.

These are capital additions.

While the "wear and tear allowance" (which allowed a 10% deduction for furnished lettings) was abolished in April 2016, it has not been replaced by a general deduction for new furniture.

Consequently, the initial cost of furnishing a property is a capital expense and is not deductible against rental income, nor is it eligible for Replacement Relief.

Defining "Like-for-Like": The 90% Rule

The phrase "like-for-like" is often misinterpreted by landlords to mean "functionally similar." In reality, HMRC guidance is more granular.

The relief allows for the replacement of an item with a new one that is broadly similar in function and quality.

However, if the new item is significantly superior to the old item, the cost is split.

You may deduct the cost of a "like-for-like" replacement, but the excess cost (attributable to the improvement) is treated as capital expenditure.

There is no statutory percentage that defines "significantly superior," but HMRC manuals and case law suggest a practical tolerance.

If the new item is functionally identical but simply a modern equivalent (e.g., replacing a 10-year-old fridge with a standard new fridge of the same dimensions and capacity), the full cost is usually allowable, even if the new model is slightly more energy efficient.

This is considered a "modern equivalent" rather than an improvement.

The problem arises when functionality changes.

Replacing a standard electric storage heater with a high-end air source heat pump system, or replacing a freestanding fridge with an integrated American-style fridge-freezer, creates a capital element.

You must apportion the cost.

If a standard replacement would have cost £500, but you purchase a superior model for £1,500, only £500 qualifies for immediate relief.

The remaining £1,000 adds to the cost base of the property for Capital Gains Tax purposes.

The Scope of Domestic Items

The relief is restricted to "domestic items." This category is explicitly defined and covers furniture, furnishings, appliances, and kitchenware.

It includes movable assets such as beds, sofas, tables, carpets, curtains, televisions, and white goods (fridges, washing machines, cookers).

It also includes smaller items like cutlery and crockery, provided they are genuine replacements.

It does not include fixtures.

The distinction between a fixture and a domestic item is critical.

A fixture is something attached to the land or building that cannot be removed without causing damage.

Examples include fitted kitchens, built-in wardrobes, boilers, and bathroom suites.

The replacement of a boiler or a bathroom suite is generally treated as a repair to the property fabric, deductible as a revenue expense under general repair rules, not under Replacement Relief.

While the tax outcome (a deduction) may appear similar, the classification dictates the documentation required and the rules regarding improvement.

Fitted vs.

Freestanding: The Grey Area

Carpets are generally treated as domestic items (movable), whereas fitted flooring (laminate or wood glued down) is often treated as part of the building fabric.

Curtains are domestic items; blinds are often considered fixtures.

This distinction changes the relief mechanism.

If you replace fitted wardrobes with free-standing wardrobes, the complexity increases.

The removal of the fitted wardrobes is a repair/restoration of the building fabric, while the purchase of the free-standing wardrobes is a replacement of a domestic item.

In practice, most landlords simply treat the entire cost as a repair if the item is fixed to the building, but claiming Replacement Relief for curtains and carpets is the correct statutory route.

Calculating the Relief: The Formula

The calculation for Replacement Relief is not always a simple deduction of the receipt.

The legislation provides a specific formula to determine the allowable amount.

The deduction is the lowest of three figures:

1.

The cost of the new item.

2.

The cost of the old item (broadly, the cost of buying a replacement of equivalent quality).

3.

The sale proceeds from the old item (if any).

In most scenarios, the cost of the new item will be higher than the cost of an equivalent old item, and the old item will have no sale value (it is scrapped).

Therefore, the deduction is usually the cost of the new item, capped at the price of a like-for-like equivalent.

If you sell the old item, you must deduct the sale proceeds from the cost of the new item.

If you sell the old sofa on eBay for £100, and buy a new sofa for £800, your relief is restricted to £700.

The "Incidental Costs" Advantage

One of the most overlooked aspects of Replacement Relief is the ability to include incidental costs.

The legislation allows you to add the costs of removing the old item and installing the new item to the "cost of the new item." This can significantly boost the deduction.

For example, if you replace a heavy double mattress in a second-floor flat, the cost of the mattress might be £400.

However, if you pay a removal company £50 to take the old one away and £50 for the delivery and installation of the new one, your total allowable cost rises to £500.

These incidental costs are often forgotten but are fully permissible under the rules.

This includes delivery charges, installation fees, and disposal fees.

Trade-offs: When NOT to Claim

There are strategic trade-offs to consider.

Replacement Relief is a revenue deduction, meaning it reduces your taxable profit and, consequently, your income tax liability.

However, if you are making a significant improvement—such as replacing a basic kitchen with a high-specification designer kitchen—the portion of the cost deemed "improvement" is a capital expense.

In some cases, landlords may prefer to treat the entire expenditure as capital to enhance the base cost for Capital Gains Tax (CGT) purposes.

This is particularly relevant if you are in a year with low profits (perhaps due to void periods or high mortgage interest) or if you anticipate selling the property in the near future at a significant gain.

By capitalising the cost, you reduce the taxable gain upon sale.

However, you cannot pick and choose arbitrarily; the classification depends on the nature of the work.

If it is a genuine replacement of a domestic item, relief is mandatory under these rules, but the "improvement" element can be capitalised.

Funding, Timing, and Cash Flow

The timing of the relief is governed by the "accruals" basis of accounting, which most landlords use.

The relief is given in the tax year in which the expenditure is incurred. "Incurred" generally means when the legal obligation to pay arises (the invoice date), not necessarily when you pay the bill, provided you are not using the cash basis of accounting.

However, many smaller landlords may be eligible to use the cash basis, where relief is given when payment is made.

This distinction is vital for year-end tax planning.

If you have a high tax bill for the current tax year and need to reduce your profit, purchasing a replacement washing machine on April 1st (before the tax year ends on April 5th) allows you to claim the relief in that year.

If you wait until April 6th, the relief falls into the next tax year.

Funding the replacement is a separate issue.

Unlike the old "wear and tear" allowance which was a flat 10% regardless of whether you spent money, Replacement Relief requires actual cash outlay.

This creates a cash-flow burden.

You must spend the money to get the tax relief.

For higher-rate taxpayers, the effective "discount" on the purchase is 40% (or 45% for additional rate), but you must front the full cost first.

Documentation and Evidence

If HMRC opens an enquiry into your Self Assessment, the burden of proof lies with you.

You must demonstrate that the expenditure qualifies.

This requires a paper trail that proves two things: the existence of the old item and its disposal, and the purchase of the new item.

Retain the following for at least 5 years after the 31 January submission deadline for the relevant tax year:

• ✅ Invoices for the new item showing the date of purchase, description, and cost.

• ✅ Receipts for delivery and installation costs.

• ✅ Evidence of disposal (e.g., a receipt from the council tip, a confirmation from a charity shop, or a screenshot of an eBay sale).

• ✅ Photographs of the old item (highly recommended to prove its condition and existence).

• ✅ Bank statements showing the outflow of funds.

• ❌ Credit card statements alone (these are often insufficient as they do not detail the item purchased).

"The relief is for the replacement of domestic items.

It is not for the improvement of the dwelling house.

The distinction between a repair to the fabric of the building and the replacement of a domestic item is a question of fact and degree." — HMRC Internal Manual PIM3210

Common Mistakes and Compliance Pitfalls

The most frequent mistake is claiming for initial furnishing.

Landlords often assume that because the property is let, items bought for the tenant are deductible.

They are not.

They are capital costs.

The second major error is failing to account for the disposal proceeds.

If you trade in an old appliance at a retailer (e.g., they take the old fridge and give you £30 off), that £30 is technically proceeds.

You must deduct it from the cost of the new item.

Ignoring this can lead to a discovery assessment by HMRC.

Another area of confusion is the "bundle." If you buy a "furniture pack" from a supplier (sofa, bed, and table for a fixed price) to replace old items, you must apportion the cost.

You cannot simply claim the total bundle cost if you are only replacing the sofa and bed, but adding a new coffee table.

The new coffee table is an addition, not a replacement, and is not allowable.

The "Landlord's Energy Saving Allowance" Overlap

Historically, there was an allowance for energy-saving items.

This has largely been subsumed or expired.

However, be careful not to double-claim.

You cannot claim Replacement Relief for an item and also claim a different capital allowance or tax relief for the same expenditure.

If you install a new energy-efficient boiler (which is a fixture, not a domestic item), you claim it as a repair/improvement to the building, not Replacement Relief.

You cannot claim Replacement Relief for fixtures.

Practical Checklist: Can I Claim?

Before entering the figure on your Self Assessment tax return (form SA105), run the expenditure through this logic check.

If the answer to all the following is "Yes," the relief is likely valid.

• ✅ Was the item a movable domestic item (furniture, appliance, furnishing)?

• ✅ Did a previous item exist in the property which was disposed of?

• ✅ Is the new item broadly similar in function to the old item?

• ✅ Have you deducted any sale proceeds from the old item?

• ✅ Have you included delivery and installation costs?

• ✅ Is the property let on a commercial basis (not rent-a-room scheme using allowance)?

Conclusion: A Relief of Last Resort?

Replacement Relief is a valuable, albeit restricted, tool for the unincorporated landlord.

It serves as a partial mitigation for the loss of the wear and tear allowance and the finance cost restrictions.

However, it requires active management.

Unlike the old flat-rate deduction, you must spend to save.

The definition of "like-for-like" is reasonably generous regarding modern equivalents, but strict regarding improvements.

The key to utilising this relief lies in rigorous documentation—specifically proving the disposal of the old asset—and a clear understanding of the boundary between a domestic item and a fixture.

For landlords looking to optimise their tax position, ensuring every eligible penny of replacement cost, including incidental expenses, is claimed is essential, but overclaiming on improvements or new items is a risk not worth taking.
