Stamp duty: do attached rights make a purchase mixed use?
In brief
For SDLT, classify the main land interest you buy. A right that comes with it does not by itself make the purchase mixed-use.
- Rights of way can be attached rights

Stamp duty: do attached rights make a purchase mixed use?
Usually, no. For stamp duty land tax, the key question is the land interest you are buying.
A right that comes with that land interest, including a right of way over neighbouring land that you do not acquire, does not by itself make the purchase mixed-use. That alone is not enough.
What this rule is about
A property deal may include the house, flat or plot itself, as well as rights over nearby land that accompany the interest being bought. Those rights may come with it.
This can matter because SDLT treats residential and mixed purchases differently.
Start with the main interest in land. Then consider any right that goes with it.
What the official source says
HMRC’s manual identifies the main subject matter as the interest in land acquired in the deal. It does not treat rights acquired alongside that interest as the main subject matter.
It draws the line there. When deciding whether land is residential, non-residential or mixed, the manual says an attached right is left out of the classification exercise. The right is disregarded.
- The main subject matter is the interest in land you acquire.
- An attached right must be acquired with that interest.
- That right does not itself change the land’s classification.
What this means in practice
Do not assume that every extra right makes a home purchase mixed-use. Start with the property interest you are buying.
Then consider whether the extra right simply goes with it.
- A right of way may be an attached right.
- A right to use land may need closer examination.
- A separate interest bought as part of the deal may have a different result.
How to analyse it
Before considering any description, right or plan connected with the transaction, ask what actual interest in land the legal documents transfer to you. Start there.
The label used in an estate agent’s details will not settle that question.
- Read the contract and transfer.
- Identify the land or property interest being bought.
- List any rights included with it.
- Work out whether each right is attached to that main interest.
Example
Maya buys a house. The transfer also gives her a right to pass over a private road owned by someone else.
If that right goes with the house, the road right does not by itself make Maya’s purchase mixed-use. The house interest remains the point to classify.
Why this can be difficult in practice
A right over other land can look separate from the property you are buying. For SDLT purposes, however, it is not always a separate purchase.
The result depends on what the legal documents give you and on how that right relates to the property.
- Plans may show land and rights differently.
- Marketing words may not match the legal title.
- A right bought separately may not be an attached right.
Key takeaways
- Focus on the main land interest you buy.
- Attached rights do not decide the classification alone.
- Check the transfer, title and plans carefully.

Official guidance
The pages below are HMRC’s guidance. Guidance is not law. It sets out how HMRC reads the legislation, and it is not binding on you, on a tribunal or on a court. Where guidance and the legislation differ, the legislation wins. HMRC can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- The boundary between an attached right and a separate interest may be unclear on particular facts.
Evidence you would need
This kind of case is decided on the facts of the individual property. These are the records that usually settle it, and the ones an adviser would ask you for.
- The contract, transfer and title plan
- Details of every right transferred or granted
- Documents showing how each right relates to the land bought
