Can You Reclaim SDLT if a Property Had Asbestos and Could Not Be Lived In?

Introduction

A common SDLT question is whether a buyer can reclaim tax because a property needed major works after completion and could not be occupied for a time. This often arises where serious defects were discovered before purchase, the price was reduced, and the buyer then had to carry out extensive remedial works.

In cases involving asbestos, stripped-out ceilings, missing insulation and temporary inability to live in the property, the key issue is not simply whether the property was inconvenient or expensive to repair. The legal question is whether, at the effective date of the transaction, the property was suitable for use as a dwelling for SDLT purposes.

That threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

The Question

A buyer purchased a residential property. Before exchange, asbestos was identified in ceilings and flooring throughout the property. The buyer negotiated a price reduction to reflect the cost of professional removal. After purchase, the removal works involved taking down ceilings, which also affected insulation, and the property could not be lived in while reinstatement works were carried out.

The question is whether those facts are likely to justify an SDLT reclaim on the basis that the property was uninhabitable or not suitable for use as a dwelling.

Nick’s Explanation

Nick’s response was cautious. He pointed the buyer to material explaining HMRC’s current approach to “uninhabitable” property claims and suggested reviewing that position before deciding how to proceed.

The substance of his reasoning can be summarised like this: where a claim depends on a property being uninhabitable, the modern case law has made these claims harder. The fact that a property required substantial works, or that the buyer could not move in immediately, does not automatically mean the SDLT residential rules do not apply.

In anonymised form, his point was effectively that the buyer needed to consider HMRC’s current stance and the developing case law before assuming that asbestos-related works would support a reclaim.

The Law

SDLT on land transactions is charged under the Finance Act 2003. Whether residential rates apply depends in part on whether the subject matter consists of a dwelling, or land that is or forms part of the garden or grounds of a dwelling.

The central statutory provision is Schedule 4ZA to the Finance Act 2003, which uses the concept of a “dwelling”. In broad terms, a building counts as a dwelling if it is used or suitable for use as a single dwelling, or is in the process of being constructed or adapted for such use.

In disputes of this kind, the argument is usually that the property was not “suitable for use as a dwelling” at the effective date of the transaction. If that argument succeeds, residential treatment may not apply in the way originally assumed.

The courts have repeatedly held that this is a factual question assessed at the effective date of the transaction. The test is not whether the property was ideal, modern, mortgageable, comfortable, or capable of immediate occupation without work. The issue is whether the building had deteriorated, or was in such condition, that it ceased to be suitable for use as a dwelling.

The Court of Appeal’s decision in Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799 confirms that the threshold is relatively high. A property will not fail the dwelling test merely because it needs repair, modernisation, or even significant remedial work. Temporary unoccupiability while works are undertaken is not enough by itself.

Analysis

The facts here need to be tested against the legal position step by step.

First, asbestos was identified before exchange. That matters because it suggests the issue was known and reflected in the agreed price. A price reduction for remedial works does not itself show that the building had ceased to be a dwelling. It often points the other way: the parties were still treating the asset as a residential property requiring repair.

Second, the presence of asbestos is serious, but not every asbestos problem makes a property unsuitable for use as a dwelling in the SDLT sense. Much depends on the condition, extent, risk, and whether the property could still function as a home at the effective date. If asbestos is present but the building still has the ordinary characteristics of a dwelling, the claim is difficult.

Third, the fact that ceilings were removed and insulation was affected appears to relate mainly to works carried out after completion. For SDLT, the relevant date is the effective date of the transaction, usually completion. The question is the property’s condition at that date, not after contractors began stripping out elements of the building.

Fourth, being unable to live in the property while works were undertaken is relevant evidence, but it is not decisive. Many homes undergoing major repairs are temporarily vacant or impractical to occupy. The courts have made clear that temporary inability to occupy does not necessarily mean the building was not suitable for use as a dwelling.

Fifth, a successful claim usually needs stronger facts than inconvenience, health concerns, or extensive reinstatement. The strongest cases tend to involve properties lacking fundamental characteristics of a dwelling at completion, such as major structural failure or the absence of basic facilities in a way that takes the property outside the ordinary concept of a dwelling. Even then, the courts apply the test strictly.

Applying that approach here, the buyer’s position looks challenging. The property was bought as a residence, the defect was identified before exchange, the price was renegotiated to reflect the remediation cost, and the inability to occupy seems tied to the removal and reinstatement works rather than proving that the building had already ceased to be a dwelling at completion.

Following Mudan, those facts are unlikely, without more, to meet the now relatively high threshold for showing that the property was not suitable for use as a dwelling.

Outcome

On these facts alone, an SDLT reclaim based on the property being uninhabitable is unlikely to be straightforward and may well fail. The presence of asbestos and the need for substantial remedial works do not automatically prevent a property from being treated as a dwelling for SDLT purposes.

The practical conclusion is that a temporary inability to live in the property during asbestos removal and reinstatement is not, by itself, enough. After Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the condition threshold is relatively high.

Practical Steps

If a buyer wants to assess whether there is any realistic SDLT reclaim position, they should gather evidence focused on the property’s condition at the effective date of the transaction, not just the scale of later works.

• Obtain the survey, asbestos reports, contractor reports and any contemporaneous photographs.
• Identify exactly what condition the property was in on completion.
• Separate defects existing at completion from damage or disruption caused by post-completion works.
• Check whether the property retained basic residential features and facilities at completion.
• Review the purchase contract, valuation material and any evidence showing why the price was reduced.
• Consider whether the facts go beyond repair and remediation and genuinely show that the building had ceased to be suitable for use as a dwelling.
• Take specialist SDLT advice before making a reclaim, particularly because weak “uninhabitable property” claims are now more exposed after Mudan.

Conclusion

A property that contains asbestos and needs major remedial works is not necessarily outside the SDLT dwelling rules. The legal test is whether it was suitable for use as a dwelling at the effective date of the transaction. Because that threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, a claim on these facts would usually need very strong evidence to succeed.
