Can you reclaim SDLT if a property was uninhabitable when you bought it?

Introduction

Many buyers ask whether they can reclaim Stamp Duty Land Tax (SDLT) if the property they bought was in such poor condition that it could not be lived in at completion. This issue usually arises where a dwelling was empty, unfurnished and in need of major works, for example because there was no working kitchen, no functioning bathroom, unsafe electrics, or extensive structural disrepair.

The difficulty is that the legal test is now strict. A property does not become “not suitable for use as a dwelling” merely because it needs renovation or modernisation. The condition 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 leasehold residential property for a modest price. At the time of purchase, the property was said to be empty, unfurnished and undergoing substantial repair. The buyer said there was no functioning toilet and no working kitchen, and that rewiring and repairs to walls and ceilings were needed from the date of purchase. Some of the work was carried out personally, with other parts done by contractors.

The buyer also had a letter from the local authority relating to council tax and major repair works, together with conveyancing documents such as the transfer, SDLT certificate, completion statement and sale contract. The question was whether this material could support an SDLT reclaim on the basis that the property was not suitable for use as a dwelling at completion.

Nick’s Explanation

Nick’s explanation focused on evidence and on the high legal threshold for this type of claim.

In anonymised form, his key points were:

• It is important to prove the exact condition of the property on the day of purchase.
• Photographs from the time of completion are especially important.
• Any survey, sales particulars, contractor invoices, receipts or other records can help verify the extent of the defects.
• A local authority letter about council tax and major repair works may support the factual picture, but it is not conclusive for SDLT.
• Following the Mudan decision, HMRC will usually require evidence that, at completion, the property had effectively lost its identity as a dwelling rather than merely needing substantial renovation.

Nick’s reasoning can fairly be summarised as follows: to persuade HMRC, it is not enough to show that the property was in poor condition. The buyer must show, with objective evidence, that the dwelling was genuinely unsuitable for use as a dwelling at the effective date of the transaction.

The Law

SDLT is charged under the Finance Act 2003. Whether residential rates apply depends on whether the subject matter of the transaction includes a “dwelling”. For these purposes, the question is whether the property was suitable for use as a dwelling at the effective date of the transaction, usually completion.

The key statutory provision is Schedule 4ZA to the Finance Act 2003, which deals with higher rates for additional dwellings. Case law has also developed the meaning of a “dwelling” and what counts as “suitable for use as a dwelling”.

The modern case law makes clear that:

• the test is applied at the effective date of the transaction;
• the test is objective;
• the fact that a property is empty, dilapidated or in need of major works does not automatically mean it is not a dwelling;
• serious disrepair must go far enough that the property is not suitable for use as a dwelling in its existing state.

In uninhabitable or “not suitable for use” cases, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. That decision reinforces that many run-down properties remain dwellings for SDLT purposes even where they require extensive renovation.

Analysis

The correct approach is to work through the facts step by step.

First, identify the relevant date. The condition that matters is the condition at completion, not what the property looked like weeks or months later after strip-out or further deterioration.

Second, gather objective evidence of that condition. The strongest evidence usually includes:

• dated photographs showing each room and any external defects;
• a survey or valuation report prepared before exchange or completion;
• auction or estate agent particulars describing the condition;
• contractor quotations, invoices and receipts close to completion;
• local authority correspondence about the property’s condition;
• completion documents confirming the nature of the property transferred.

Third, separate evidence of disrepair from evidence of legal unsuitability as a dwelling. For example:

• No functioning kitchen may help, but it is not always decisive.
• No functioning toilet or bathroom may be more serious, especially if there were no basic sanitary facilities at all.
• Unsafe electrics may be important if they made occupation realistically impossible.
• Damage to walls and ceilings may support the case, but much depends on severity.
• The fact that the property was empty and unfurnished helps very little on its own.

Fourth, consider the local authority material carefully. A council tax letter about major repair works can support the buyer’s account, but council tax rules are different from SDLT rules. A property may qualify for a council tax discount or exemption because it is empty and under repair, yet still be treated as a dwelling for SDLT purposes.

Fifth, assess whether the defects show the property had effectively ceased to function as a dwelling. This is where many claims fail. A property can be unpleasant, outdated, partly stripped out, or in need of major investment and still remain suitable for use as a dwelling in law.

On the facts described here, the buyer appears to have some supportive evidence:

• the property was empty and unfurnished;
• there were photographs from around the time of purchase;
• there was local authority correspondence referring to major repair works;
• there was evidence that no functioning toilet and no working kitchen were present;
• rewiring and fabric repairs were required immediately.

Even so, the real question is whether that evidence is strong enough to meet the post-Mudan threshold. If the property still retained the basic character of a flat or house and could, viewed objectively, still be regarded as a dwelling needing renovation, HMRC may reject the reclaim. If, however, the evidence shows that essential facilities were absent and the condition was so severe that occupation as a dwelling was not realistically possible at completion, the claim may be arguable.

Outcome

A buyer in this position may have grounds to explore an SDLT reclaim, but success depends on the quality of the evidence and whether the property’s condition crossed the now demanding legal threshold.

The practical conclusion is this: needing substantial works is not enough. The buyer must be able to show that, at completion, the property was genuinely not suitable for use as a dwelling. After Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, that is a relatively high bar.

Practical Steps

If you are assessing this type of SDLT position, you should:

• collect all photographs showing the property exactly as it was at completion;
• obtain any survey, valuation or lender report prepared before purchase;
• find the sales particulars, auction pack or marketing description if available;
• gather contractor invoices, quotations and receipts dated close to completion;
• keep local authority correspondence relating to condition, occupation or repair works;
• review the transfer, contract, completion statement and SDLT filing documents;
• prepare a clear chronology showing the condition on completion and the works carried out afterwards;
• focus on evidence of missing essential facilities and serious defects, not just general disrepair.

If the evidence mainly shows renovation, refurbishment or improvement works, rather than a property that had ceased to be a dwelling, the reclaim is less likely to succeed.

Conclusion

You can only reclaim SDLT on this basis if the property was genuinely not suitable for use as a dwelling at completion. Evidence such as photographs, surveys, invoices and local authority correspondence can help, but the legal threshold is now high. After Mudan, many properties needing major works will still be treated as dwellings for SDLT purposes.
