How do refurbishment costs affect the SDLT personal representative relief and the permitted amount?

Introduction

Buyers sometimes ask whether major renovation works will prevent them from claiming the stamp duty land tax relief that can apply when a dwelling is bought from personal representatives. A common concern is whether the planned works will exceed the “permitted amount”, especially where the property is in poor condition and needs extensive repairs, replacement services, or safety-related work.

This issue matters because the rules distinguish between different types of expenditure. Some costs may count towards the permitted amount, while others may be excluded, for example where they are genuinely required to deal with serious safety issues. The distinction is highly fact-sensitive and often turns on the evidence available at the time of purchase and refurbishment.

It is also important to separate this relief from the separate SDLT question of whether a property was suitable for use as a dwelling on the effective date of the transaction. In that separate context, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

The Question

A company is buying a residential property from personal representatives. The property is in very poor condition and the buyer intends to renovate and resell it. The planned works include replacement plumbing, rewiring, roofing, windows, and making the kitchen and bathrooms usable and safe.

The buyer wants to know how to assess whether the refurbishment costs will stay below the permitted amount for the relief. In particular, the buyer wants to understand whether some of the expenditure can properly be excluded because it is needed to bring the property up to modern safety standards, and whether a surveyor’s report and itemised contractor pricing would help support that position.

Nick’s Explanation

Nick’s response was that the treatment of refurbishment costs is detailed and can be contentious. In anonymised form, his explanation was that there is often disagreement about “which types of work are necessary for safety, which are considered repairs, and which are enhancements”. He also noted that transactions involving a low acquisition price or significant refurbishment are likely to attract scrutiny from HMRC.

That is the key practical point. The answer rarely depends on labels alone. Calling expenditure “safety works” will not decide the issue. What matters is the real nature of the works, why they were needed, and whether the evidence shows that the expenditure falls within the statutory treatment for the relief.

Nick’s comments also support a careful evidential approach. A properly instructed surveyor can help identify the condition of the property at acquisition, the defects present, the risks involved, and which works were necessary to address those defects. Separately, a builder’s quotation or contract schedule that breaks costs down line by line can help show what was spent on each category of work. That said, the evidence must be objective and credible. It should explain the condition and need for the works, not simply be drafted to maximise excluded expenditure.

The Law

The relevant SDLT rules are found in the Finance Act 2003 provisions dealing with relief for certain acquisitions from personal representatives. Where the statutory conditions are met, the relief can be lost if refurbishment expenditure exceeds the permitted amount within the relevant period.

The legal analysis usually requires attention to:

• the statutory conditions for the personal representative relief;
• the definition of refurbishment expenditure for the purpose of the permitted amount test;
• whether particular items are properly characterised as repairs, improvements, replacements, or safety-related works;
• any statutory or HMRC-recognised exclusions from the expenditure that counts towards the permitted amount; and
• the timing of the expenditure and the evidence showing what the works were for.

In practice, the legislation must be read together with HMRC guidance and applied to the facts. The words used in invoices are relevant but not conclusive. HMRC and the tribunal will look at the substance of the works.

Where readers are also considering whether a property was uninhabitable or not suitable for use as a dwelling, that is a separate legal question. The leading modern authority is Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, which confirms that the threshold is now relatively high. Serious disrepair alone does not automatically mean a building is not suitable for use as a dwelling.

Analysis

The starting point is to identify exactly what works are proposed and why.

If a property needs new plumbing and wiring, the first question is whether the existing systems are defective, dangerous, or beyond repair, or whether the buyer is simply replacing dated but functioning systems as part of a modernisation project. A full rewire because the installation is unsafe is easier to argue as necessary safety-related work than a rewire done mainly to improve layout, capacity, or specification.

The same applies to windows and roofing. Replacing broken or dangerous elements may be different from upgrading serviceable items to a better standard. If the roof is failing and allowing water ingress that creates immediate structural or safety risks, that is materially different from replacing an old roof to improve energy performance or appearance.

Kitchens and bathrooms often create mixed categories of expenditure. If sanitary facilities are unusable, dangerous, or fail basic safety requirements, some of the work may be necessary to make the property safe and functional. But if the project also includes redesign, enlargement, higher-specification fittings, or layout changes, those elements may be treated as improvements rather than excluded safety expenditure.

This is why a condition-led report is useful. A surveyor should record:

• the state of the property at acquisition;
• the defects present in each element;
• whether each defect creates a safety hazard, functional failure, or ordinary disrepair;
• what remedial works are necessary to address that defect; and
• whether any part of the proposed work goes beyond what is necessary.

A Housing Health and Safety Rating System assessment can be a helpful reference point because it focuses on hazards and risk. But it is not, by itself, the legal test for every SDLT question. It is best used as supporting evidence rather than as a substitute for the statutory analysis.

The buyer should also ensure that the contractor’s pricing mirrors the surveyor’s analysis. If the quote simply gives one figure for “full refurbishment”, it will be difficult to prove which costs should be counted and which should be excluded. A better approach is a detailed schedule separating, for example, dangerous electrical replacement, essential plumbing remediation, roof defect repairs, and any non-essential upgrades or enhancements.

Even then, care is needed. HMRC may challenge an allocation that appears artificial or overly convenient. The more the documents were prepared contemporaneously, independently, and with clear technical reasoning, the stronger the evidential position will be.

It is also important not to confuse “repair” with “excluded expenditure”. Some repairs may still count, depending on the statutory wording and the nature of the relief being claimed. Likewise, some replacement works may partly address safety issues but also partly improve the property. Mixed expenditure may need to be apportioned on a principled basis.

Finally, if the purchase price is low relative to the property’s potential value after works, HMRC may look closely at whether the transaction and subsequent expenditure fit the relief conditions. That does not mean the claim fails, but it does mean the evidence should be assembled carefully from the outset.

Outcome

The practical conclusion is that a surveyor’s report and itemised building costs can be very helpful, and in many cases they are essential. However, they must be used to document the true condition of the property and the genuine necessity of the works, not simply to maximise excluded expenditure by description alone.

If significant parts of the project are genuinely required to remedy dangerous defects or bring the property up to a safe standard, there may be a sound basis for excluding those costs from the permitted amount calculation, depending on the precise statutory rules. But extensive modernisation, redesign, or enhancement is less likely to be excluded.

Practical Steps

• Obtain a detailed pre-works survey from a suitably qualified surveyor with experience in residential defects and hazard assessment.
• Ask the surveyor to distinguish clearly between safety-critical works, essential remedial works, ordinary repairs, and improvements or enhancements.
• Keep photographs, videos, and contemporaneous notes showing the property’s condition on acquisition.
• Obtain itemised contractor quotations and invoices that follow the same categories used in the surveyor’s report.
• Avoid broad descriptions such as “full refurbishment” where separate categories can be identified.
• Check the statutory wording of the personal representative relief and the permitted amount test against each item of expenditure.
• Review whether any part of the project goes beyond what is necessary to remedy defects or hazards.
• Keep a clear timeline showing when each item of expenditure was incurred.
• If the figures are close to the permitted amount, obtain specialist SDLT advice before completion of the works if possible.

Conclusion

Whether refurbishment costs stay within the permitted amount depends on the real character of the works and the quality of the evidence. Necessary safety-related works may be treated differently from general refurbishment or enhancement, but the line can be fine. A careful survey, properly itemised costings, and a disciplined legal analysis are the best way to assess the position.
