Do two titles bought together count as one SDLT transaction, and can separate woodland make the purchase mixed-use?

Introduction

Buyers often ask whether Stamp Duty Land Tax (SDLT) should be worked out separately where a property is made up of more than one title, especially if one title contains a house and another contains woodland or other land. A related question is whether the purchase can be treated as mixed-use, so that non-residential SDLT rates apply to the whole transaction.

These questions matter because the SDLT difference can be large. The answer depends less on how the seller acquired the land in the past, and more on what the buyer acquired in the transaction and whether any part of that subject matter was genuinely non-residential at the effective date.

The Question

A buyer purchased a property at auction for just over £1.2 million. The purchase included two registered titles acquired together in one auction lot and completed in one transaction. One title included a dwelling. The other included woodland and surrounding land. The total area was said to be about 5.94 acres.

The buyer wanted to know:

• whether SDLT should be calculated separately for each title or as one combined transaction; and
• whether the woodland or other land might allow the purchase to be treated as mixed-use, so that non-residential SDLT rates would apply.

Nick’s Explanation

Nick’s reasoning was that the starting point is to look at what was bought in the transaction, not how the seller had assembled the land historically. If two titles are bought together under one contract or one auction lot, that will usually be treated as a single land transaction for SDLT purposes unless there is a real legal basis for splitting it.

On the mixed-use point, Nick identified features that could support an argument that the woodland was not part of the residential grounds of the dwelling. In anonymised form, the points he highlighted included:

• the woodland was held under a separate title;
• it was not immediately adjacent to the dwelling;
• it appeared to be accessible to the public and unfenced;
• planning or title restrictions limited development or adaptation;
• tree protection restrictions limited how the land could be used; and
• overall, there was an argument that the land was not held for the benefit of the dwelling.

He also identified points against mixed-use treatment:

• the land was still near the house;
• the title documentation suggested the land was to be used only for the enjoyment of the dwelling; and
• there was no separate commercial activity or agreement showing an independent non-residential use.

Nick’s later view was that, on the facts he had reviewed, there was a basis for arguing that the property should be classified as mixed-use. At the same time, he recognised that HMRC would be likely to examine a claim of that kind closely.

The Law

SDLT is charged under the Finance Act 2003. The key distinction here is between:

• residential property, which is taxed at residential rates; and
• non-residential or mixed property, which is taxed at non-residential rates.

Under section 55 Finance Act 2003, different rate tables apply depending on the nature of the property. Broadly, a transaction is residential if the subject matter consists entirely of residential property. If any part of the subject matter is non-residential property, the transaction can fall within mixed-use treatment.

For SDLT purposes, “residential property” includes a building used or suitable for use as a dwelling, and land that is or forms part of the garden or grounds of that dwelling. That “garden or grounds” question is often the real issue in cases involving paddocks, woodland, fields, strips of land and amenity land.

Where several interests are acquired from the same seller as part of one deal, SDLT usually looks at the transaction as a whole. The fact that land is divided into separate Land Registry titles does not by itself mean there are separate SDLT transactions. Separate titles are relevant evidence, but they are not decisive.

Case law has shown that the question is intensely fact-sensitive. Tribunals and courts look at matters such as:

• physical layout and proximity to the dwelling;
• whether the land is enclosed with the house or separate from it;
• how the land is actually used;
• whether the land is capable of ordinary domestic enjoyment with the house;
• title restrictions and planning controls;
• whether there is any independent commercial or public use; and
• the character of the property as a whole at the effective date.

Where a buyer argues that a dwelling was not suitable for use as a dwelling at completion, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. Ordinary disrepair, age, or the need for renovation will often not be enough. The same practical lesson applies more generally in SDLT disputes: HMRC and the courts now take a stricter approach to arguments that seek non-residential treatment unless the facts are strong.

Analysis

The analysis usually has two stages.

First, is this one SDLT transaction or more than one? If the buyer purchased both titles together in a single auction lot, with one price and one completion, the normal view is that SDLT is assessed on the acquisition as one transaction. The seller’s earlier separate purchases do not usually matter. SDLT is concerned with the buyer’s acquisition, not the seller’s acquisition history.

So the practical answer to the first question is usually that the two titles are not taxed separately just because they are separate titles. They are usually treated together.

Second, what is the nature of the property acquired as a whole? If all of the land falls within the dwelling and its garden or grounds, the transaction is residential. If any meaningful part of the subject matter is genuinely non-residential, the transaction may be mixed-use.

In a case involving woodland, the key question is whether that woodland forms part of the grounds of the dwelling. Relevant points include the following.

• If the woodland is physically detached, not contiguous in any practical sense, or accessed separately, that may help a mixed-use argument.
• If it is open to the public, unfenced, or otherwise not under the normal domestic control of the homeowner, that may also help.
• If title covenants or public law restrictions prevent ordinary domestic use or enjoyment, that may point away from the land being residential grounds.
• If the land has an independent non-residential function, such as commercial exploitation, agricultural use, or public amenity characteristics, that may strengthen the case.

Against that, HMRC will often argue that woodland near a house is still part of the property’s amenity and therefore part of its grounds, especially where:

• it was marketed with the house as one country home package;
• the title links the land to the enjoyment of the dwelling;
• there is no genuine independent use; and
• the buyer acquired it as part of the same residential purchase.

Separate title numbers alone are not enough. Nor is the fact that the land cannot be built on. Land can still be part of the grounds of a dwelling even if development is prohibited.

On the facts described here, there appears to have been an arguable basis for saying the woodland was not part of the dwelling’s grounds, particularly because it was separate land and said to be physically separate from the house. But the contrary points were also real, especially if the title documents tied the woodland to the dwelling’s enjoyment. That means the case sits in the fact-sensitive middle ground rather than being an obvious mixed-use claim.

Outcome

The practical conclusion is:

• the two titles would usually be treated as one SDLT transaction if they were bought together in one auction purchase; and
• the whole purchase might still qualify as mixed-use if the woodland was genuinely non-residential and not part of the dwelling’s garden or grounds, but that would depend on the detailed facts and documents.

In other words, the existence of two titles does not itself split the SDLT calculation. The real issue is classification of the subject matter acquired.

Practical Steps

If you are assessing a similar purchase, the following steps are sensible:

1. Review the contract, transfer and auction particulars to confirm whether the acquisition was one transaction or several.
2. Obtain title plans for each title and compare them with the physical layout on the ground.
3. Check whether the land is fenced, enclosed, separately accessed, or physically detached from the dwelling.
4. Review title covenants, easements and restrictions to see whether the land is legally tied to the dwelling’s enjoyment.
5. Check planning status, Tree Preservation Orders and any other restrictions affecting use.
6. Gather evidence of actual use at the effective date, including photographs, videos, site plans and any evidence of public or commercial use.
7. Consider how the property was marketed. If the land was presented as part of the home’s amenity, that may weaken a mixed-use argument.
8. Calculate SDLT both ways so you understand the tax difference and the litigation risk.
9. If filing on a mixed-use basis, ensure the return position is supportable by contemporaneous evidence in case HMRC opens an enquiry.

If the argument instead is that the dwelling was uninhabitable or not suitable for use, take particular care. Following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the threshold is now relatively high.

Conclusion

Where a house and separate woodland are bought together, SDLT is usually assessed on the acquisition as one transaction. The more difficult question is whether the woodland is part of the dwelling’s grounds or is genuinely non-residential. If it is genuinely non-residential, the whole transaction may be mixed-use and taxed at non-residential rates. That outcome depends on the facts, the title documents and the physical character and use of the land at completion.
