Stamp duty when flat owners buy their block’s freehold
In short
When tenants use a statutory collective right to buy their block’s freehold, SDLT can be calculated by dividing the total amount between the participating qualifying flats first.
- The nominee may claim through the SDLT return.
- Each participating flat matters, including two flats held by one tenant.
- Check the current higher-rate rules where the divided figure exceeds £500,000.

Stamp duty when flat owners buy their block’s freehold
When flat owners act together to buy their block’s freehold, stamp duty does not always use the full price in the usual way. Under the law, the calculation can split the total between the flats taking part first. That can reduce the SDLT bill.
What this rule is about
Buying a freehold for a whole block is one deal. Yet the people taking part may be buying it for several separate flats.
Section 74 of the Finance Act 2003 tries to reflect that reality. It applies where tenants use a legal group right to buy the freehold and appoint someone to buy it for them.
That person can be one individual, several people or a company. People often call them the nominee or appointee.
What the official source says
HMRC’s manual says that you divide the total amount paid for the freehold by the number of flats whose qualifying tenants are taking part. You work out SDLT on that smaller figure. You then multiply the result by the number of those flats.
Two routes appear in the legislation:
- the right of first refusal under the Landlord and Tenant Act 1987;
- the right to collective enfranchisement under the Leasehold Reform, Housing and Urban Development Act 1993;
- a purchase made by a person nominated or appointed by the tenants;
- flats held by qualifying tenants who are actually taking part.
This is the key point: the calculation counts flats, not simply people. If one participating tenant holds two flats, both flats can count if each meets the test.
HMRC says the claim should be made in the land transaction return using relief code 25. For a notifiable transaction, the statutory return deadline is 14 days after its effective date.
What this means in practice
This rule can stop tax authorities from treating a group purchase as though one buyer had bought one very expensive home. Instead, it tests the amount per participating flat first.
It is a calculation rule, not a full exemption. SDLT may still be due. Your rate depends on the rate that applies to the divided figure.
- Count only the flats held by tenants taking part.
- Do not divide by every flat in the block automatically.
- Keep clear records where one tenant holds more than one flat.
- Make sure the person named on the purchase papers was properly appointed.
- Put the claim into the SDLT return if the transaction is notifiable.
There is an important limit. If the divided figure is more than £500,000, a separate test applies for companies, certain partnerships and collective investment schemes.
According to the HMRC page, a company purchase over £500,000 attracts a 15% charge. That is not the full statutory test. For this purpose, the law first looks at the divided figure, not just the full amount paid.
How to analyse it
Start with the legal route used to buy the freehold. The title “collective enfranchisement” alone is not enough: the documents should show the statutory right being exercised.
- Identify whether the right of first refusal or collective enfranchisement is being used.
- Check who has been nominated or appointed to complete the purchase.
- List each participating qualifying tenant and each flat they hold.
- Count the participating qualifying flats.
- Divide the total amount used for SDLT by that number.
- Check whether that figure is £500,000 or less.
- If it is higher, check the company or investment-scheme condition.
- Apply the SDLT calculation required by section 74.
If the divided figure is £500,000 or less, section 74 directs you to calculate SDLT on that figure and multiply the answer by the number of qualifying flats.
If it is above £500,000 and the Schedule 4A company condition is met, that special calculation does not apply.
Example
Eight flats take part in buying a ten-flat block’s freehold for £500,000. One of the tenants holds two of the eight participating flats. The count is still eight flats, not seven people.
Divide £500,000 by eight. The figure is £62,500 per participating flat. HMRC’s example says the SDLT rate on that figure is 0%, so multiplying the result by eight still gives £0 SDLT.
Change one fact and the result may differ. If only six qualifying flats take part, the figure becomes £83,333.33 per flat. The calculation still starts there, but the applicable SDLT rate must then be checked.
Why this can be difficult in practice
The maths is simple. Getting the starting facts right is harder.
People often divide by every flat in the building. That is wrong if some tenants are not taking part. Equally, counting one tenant only once can be wrong where they hold more than one participating flat.
- The legal status of each tenant may need checking.
- A tenant may hold more than one flat.
- Some flats in the block may not take part.
- The nominee’s role must match the statutory process.
- Company involvement can change the outcome where the divided figure exceeds £500,000.
- HMRC guidance is not the law and its quoted 15% rate is out of date against the supplied statutory text.
The supplied legislation records a 17% rate for the company higher-rate outcome, rather than 15%. Because this statutory copy is current only to 17 November 2025, a later transaction needs a current legislation check before a return is filed.
Key takeaways
- Group freehold purchases can be taxed by reference to the amount per participating flat.
- Count participating qualifying flats, not simply tenants or all flats in the block.
- The company higher-rate test applies only after the per-flat division step.

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
- Whether a tenant and flat meet the housing-law definitions depends on the particular statutory right being used and the facts of the block.
- The supplied statutory material is current only to 17 November 2025. The applicable rates and wording must be checked against current legislation for a transaction after that date.
- HMRC’s manual is guidance, not law. Its broad statement that a company paying over £500,000 faces the higher rate leaves out the statutory first step of dividing the total amount by participating qualifying flats.
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.
- documents showing which statutory collective right is being exercised
- the nomination or appointment of the person buying the freehold
- a list of participating tenants and the flats each holds
- the agreement and calculation of the total amount paid for the freehold
- the completed SDLT return and relief claim details
