Can a company buy a property to rescue a broken chain and claim SDLT relief?

Introduction

People often search for this issue when a sale collapses and they need another way to keep a property chain moving. A common idea is to use a company they already own to buy one of the properties, then sell it on later or let it out in the meantime. The key question is whether that company purchase can qualify for any Stamp Duty Land Tax relief, especially what is sometimes called “broken chain relief”.

The answer depends very heavily on the exact statutory conditions. In many cases, the fact that a purchase helps a chain complete is not enough on its own. The buyer must fit within a specific relief in the Finance Act 2003, and the intended use of the property matters.

The Question

A homeowner was trying to sell their existing home and buy another dwelling. Buyers had pulled out on both sides of the chain. To keep the purchase moving, the homeowner considered having a company they owned buy the new property instead, with the intention of letting it to an unconnected third party and possibly selling another property later.

The homeowner wanted to know whether the company purchase could be exempt from SDLT under a form of “broken chain relief”, and if not, whether any other SDLT treatment might reduce the tax.

Nick’s Explanation

Nick’s main point was that the relief being considered was not generally available just because a company purchase would rescue a chain. He explained that the relevant SDLT reliefs in this area are aimed at property traders, and that if the company intends to hold the property rather than acquire it in the course of a qualifying property trading activity, the relief is unlikely to apply.

In anonymised form, his explanation was:

“The stamp duty exemptions you mentioned are only applicable to property traders, and since you intend to hold the property, this exemption will not apply in your case.”

He then identified the only other possible angle raised by the facts: whether the property was so defective at completion that it could be treated as unsuitable for use as a dwelling, so that non-residential rates might apply instead of residential rates.

However, once it was confirmed that the property was in good, liveable condition, that route also appeared unavailable.

The Law

SDLT is charged under the Finance Act 2003. Whether residential or non-residential rates apply depends on the nature of the subject matter acquired at the effective date of the transaction.

Where a property is a dwelling, residential rates usually apply. If the buyer is a company acquiring a dwelling, higher charges may also need to be considered, including the higher rates for additional dwellings and, in some cases, the 15% rate for certain enveloped dwellings, subject to reliefs.

Some SDLT reliefs are available for property traders. These are not broad fairness-based exemptions for transactions that help a chain complete. They apply only where the statutory conditions are met. In outline, reliefs of this kind normally require the purchaser to be carrying on a qualifying property trade and to acquire the property for the purposes of that trade, not simply to retain it as an investment or to let it out.

Separately, there has been substantial litigation on when a building is not suitable for use as a dwelling at the effective date of the transaction. That issue affects whether residential or non-residential rates apply. The modern case law shows that the threshold is relatively demanding. In an uninhabitable or not suitable for use case, the condition thresholds are now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

Analysis

The first step is to identify what the company is actually doing. If the company is buying the property to hold it, let it to a third party, and possibly sell later, that normally looks like an investment acquisition rather than a qualifying property trading acquisition.

That matters because a relief sometimes described informally as “broken chain relief” is not triggered simply because a chain has broken and the company steps in. The legislation does not create a general SDLT exemption for chain rescue purchases. The buyer must fall within the wording of the relevant relief.

On the facts described, the intended arrangement was:

• a company connected with the homeowners would buy the target property;
• the purchase would help the chain proceed;
• the property would then be let to an unconnected third party rather than immediately turned over in a qualifying trade.

That combination is usually inconsistent with property trader relief. A company that acquires and holds a dwelling as a rental investment is generally not buying it “as a property trader” for the purpose required by the relief.

The second step is to consider whether the property could instead be treated as non-residential because it was unsuitable for use as a dwelling at completion. This argument can sometimes arise where a property has major defects, lacks essential facilities, or is in such poor condition that it cannot realistically be lived in at the effective date.

But that route depends on the actual physical condition of the property, not on the buyer’s plans. If the property is in good and liveable condition, it will usually remain a dwelling for SDLT purposes. Minor disrepair, cosmetic issues, or the buyer’s intention to refurbish are not enough. Following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the threshold for showing that a property is unsuitable for use as a dwelling is now relatively high.

So, where:

• the company intends to hold or let the property, and
• the property is in good condition and capable of occupation,

there is usually no basis for claiming either property trader relief or non-residential treatment on “unsuitable for use” grounds.

The practical result is that the acquisition will normally be taxed as a residential company purchase in the ordinary way, with any applicable surcharges considered under the standard SDLT rules.

Outcome

Using a company to buy a property in order to keep a chain alive does not, by itself, create an SDLT exemption. If the company is acquiring the property to hold it or let it out, relief aimed at property traders is unlikely to apply.

If the property is in good, liveable condition, it is also unlikely to qualify for non-residential treatment on the basis that it is unsuitable for use as a dwelling.

In a case like this, the likely outcome is that normal residential SDLT rules apply to the company purchase.

Practical Steps

If you are assessing a similar transaction, the sensible approach is:

• identify exactly which SDLT relief you think applies by reference to the Finance Act 2003, not by a general description;
• check whether the buyer is genuinely carrying on a qualifying property trade and whether the purchase is for that trade;
• review the intended use of the property immediately after purchase, especially whether it will be held as an investment or rental asset;
• consider the property’s physical condition at the effective date of the transaction, with photographs, surveys, and contemporaneous evidence if “unsuitable for use as a dwelling” is being considered;
• remember that after Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the condition threshold for an uninhabitable argument is relatively high;
• ask the conveyancing solicitor and tax adviser to confirm the SDLT basis before filing the return, because the SDLT return should reflect the correct treatment from the outset.

Conclusion

A company purchase that rescues a broken property chain is not automatically exempt from SDLT. If the company intends to hold or let the property, property trader relief is unlikely to be available. And if the property is habitable, non-residential treatment is also unlikely. The real answer lies in the statutory conditions and the detailed facts of the transaction.
