LTT compulsory purchase relief when a sale is agreed
Agreed sales and compulsory purchase relief
For Welsh LTT, agreement on a price or sale terms does not by itself prevent compulsory purchase relief. The key issue is whether the body that made the compulsory purchase order actually buys the land.
- The purchase must facilitate development by another person.
- The public body must be the buyer under its compulsory purchase order.
- A direct sale from the owner to the developer cannot use this relief.

LTT compulsory purchase relief when a sale is agreed
An agreed price does not automatically stop Land Transaction Tax relief for a compulsory purchase in Wales.
Who buys the land under the compulsory purchase order is the key question. If the public body buys it, relief may still apply. If the owner sells straight to a developer, it cannot.
What this rule is about
This rule concerns a narrow LTT relief. LTT is the Welsh tax sometimes described as stamp duty on land purchases. This relief allows a public body to obtain project land through compulsory purchase powers.
Before the order takes effect, the landowner, local authority and developer will often discuss a sale, agree a price or other terms, and expect the authority to acquire the land under its order before the developer’s project proceeds. That is not unusual. Agreement itself is not a reason to deny relief.
What matters is the route the land takes. That distinction can decide whether the authority’s purchase is relieved from LTT.
What the official source says
Official guidance says that relief is not blocked when the seller and developer have an agreement, provided the other conditions are met and the public body obtains the land under its order.
Legislation disregards acquisition method, including agreement.
- The buying body must have made the compulsory purchase order.
- That body must buy the land under its order.
- The purchase must help development by another person.
- The developer must be someone other than the body making the order.
- The parties may already have agreed a price.
- The parties may also have agreed other sale terms.
- A direct sale from the owner to the developer does not receive this relief.
In this context, “development” has the meaning used in planning law. The source does not set out that wider definition. Simply labelling a project as development is not enough.
What this means in practice
A deal can remain compulsory. Agreement on the price does not decide the issue here. An agreed purchase can still be made under a compulsory purchase order.
Yet an agreement cannot change who bought the land.
Where the authority buys from the owner under its order and later makes land available for the developer’s project, relief may be available despite a prior agreement on price or terms.
Buyer identity decides. If the developer buys direct, the authority was not the buyer.
- Check the name of the buyer in the transfer document.
- Check who made the compulsory purchase order.
- Check whether the order covers the land being bought.
- Read any agreement between the owner and developer.
- Keep evidence of the planned third-party development.
- Do not rely on the project name alone.
How to analyse it
Begin with the legal route, not the commercial story. A project may involve an authority and a developer, but the documents may show that only one of them actually bought the land.
- Is there a compulsory purchase order?
- Who made that order?
- Who is named as buyer in the land transfer?
- Does that buyer obtain the land under its own order?
- Will another person carry out the development?
- Does the project fall within the planning-law meaning of development?
- Was the land instead sold directly to that other person?
Where the last answer is yes, the official source gives a clear outcome: this compulsory purchase relief cannot be claimed for that direct sale.
For this relief, the authority must be the buyer.
Example
A council makes a compulsory purchase order. The land is needed for a redevelopment scheme.
Before the transfer, the owner and a developer agree the price and terms. The council then buys the land from the owner under its order, so the agreement does not by itself prevent relief.
Change one fact: the owner transfers the land straight to the developer. The council has not bought it, so this relief is unavailable.
Why this can be difficult in practice
A developer may fund work, negotiate with the owner, or expect to receive the site later, even while the authority acquires the land under its order for a project the developer will carry out. None of those facts alone answers the LTT question.
People often confuse agreement with a direct sale. The transfer, order and parties’ roles must match.
- A negotiated price does not necessarily mean the relief fails.
- Developer involvement does not make the developer the buyer.
- A later transfer to a developer is different from a direct first sale.
- The project must facilitate development by someone other than the ordering body.
- Whether works are development may need careful planning-law analysis.
Key takeaways
- An agreed purchase can still qualify for this LTT relief.
- The body making the compulsory purchase order must buy the land.
- A direct sale from the owner to the developer does not qualify.

Official guidance
The pages below are the Welsh Revenue Authority’s guidance. Guidance is not law. It sets out how the Welsh Revenue Authority 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. the Welsh Revenue Authority can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- Whether particular works amount to development depends on the statutory planning definition and the facts.
- An agreement may involve several linked contracts. The documents must show who actually buys the land and under what order.
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 compulsory purchase order and details of the body that made it.
- The sale contract, transfer and any agreement on price or other terms.
- Evidence showing that a third party will carry out the development.
- Documents showing the route of ownership from landowner to buyer.
