Stamp duty on six flats later turned into a hotel
In short
HMRC’s historic example says that converting six rented flats into a hotel within two years can undo the tax reduction claimed on purchase.
- The tax is recalculated using the full price.
- The example treats the property as non-residential.
- A further SDLT return and payment are due within 30 days.

Stamp duty on six flats later turned into a hotel
When six rented flats are bought, the stamp duty calculation can begin as one for homes, but starting work later to turn them into a hotel can change it. HMRC’s example says extra tax becomes due when the work starts.
This is an historic example about the tax reduction for buying more than one home at once. For this purpose, the purchase date matters. It cannot safely be used as proof that the same relief is available now.
What this rule is about
Under the old multiple-home relief, buying homes together spread the tax calculation across those homes rather than treating the whole price as one purchase. That could lower the bill.
If a later change affected qualification within the relevant period, the law looked back and recalculated the purchase as though that change had happened before the tax date. That could undo the earlier result.
Harsh as that may sound, it can produce a large extra bill.
What the official source says
HMRC’s manual gives an example of a freehold building containing six flats. A buyer pays £1.2 million and claims the relief. Each flat has an assured shorthold tenancy.
Because each flat has an assured shorthold tenancy, HMRC says the buyer has bought the superior interest in six homes for this historic relief purpose. Its manual applies the historic averaging calculation.
- The total price is £1.2 million.
- There are six flats.
- The starting figure for the averaging calculation is £200,000 per flat.
- The tax on that figure is then multiplied by six.
- HMRC says the higher rates for additional homes apply in its example.
- HMRC also says non-UK-resident rates may apply if any buyer is not UK resident.
- Two years after the purchase, the tenancies end.
- The buyer then starts work to convert the building into a hotel.
A hotel does not count as residential property for SDLT. Under HMRC’s stated facts, conversion work means that the flats are no longer suitable for use as homes once work on the hotel project begins. That change matters.
As the conversion begins two years after the purchase, HMRC’s manual says it happens within the three-year period that matters for the historic relief. The purchase therefore stops qualifying.
- The law treats the later event as if it happened just before the original tax date.
- The calculation no longer uses six separate homes.
- The whole £1.2 million becomes the figure used for the new calculation.
- The property is treated as non-residential for that recalculation.
- The buyer must send a further SDLT return within 30 days of the work starting.
- Any extra tax must be paid by that filing date.
What this means in practice
After completion, do not assume that the tax treatment is fixed forever, because a planned change of use can matter even when it occurs much later. Timing can change the result.
For HMRC’s example, the key moment is not when the hotel opens but when the conversion work begins. That is the important date.
- Keep a clear record of the first day of work.
- Check whether that day falls within the relevant period.
- Review the SDLT calculation before work begins.
- Work out whether the building still counts as homes at that point.
- Allow for a further return and possible extra payment.
How to analyse it
Begin with the original purchase, then work forward through what happened afterwards. Dates and evidence matter more than labels.
- Find the SDLT effective date, usually the key tax date.
- Check the relief claimed on the original return.
- Confirm how many homes the buyer acquired.
- Read the leases and confirm their original terms.
- Identify the first real conversion activity.
- Decide whether that work made the flats unsuitable as homes.
- Check whether the event fell within the relevant period.
- Recalculate using the rules that applied on the original tax date.
What actually decides the result when rented flats are turned into a hotel project is both the change itself and the point at which that change began. Timing decides it.
Example
Sam buys a building with six rented flats for £1.2 million. For the historic relief calculation, dividing £1.2 million by six gives £200,000 for each flat, which the initial tax calculation uses subject to the higher rates in HMRC’s example. That is the starting position.
Two years later, Sam’s tenants leave, and builders start stripping out the flats for a hotel conversion; HMRC’s example treats that start date as the event ending the relief. The tax is then recalculated using the full £1.2 million and non-residential treatment.
Sam must not wait for the hotel to open. Under the example, the further return is due within 30 days after the builders start work.
Why this can be difficult in practice
People often focus on the finished building, but that misses the point in HMRC’s example because the first conversion work can be the date that matters. Evidence of that work is important.
Not every repair, empty period or discussion about a hotel has the same effect, since the facts must show what changed and whether the flats remained suitable as homes. Labels alone are not enough.
- Planning permission alone may not show when work began.
- An empty flat is not automatically unsuitable as a home.
- Early site activity may need careful evidence.
- Work on only part of a building can raise harder questions.
- The original tax date may change which version of the law applies.
- HMRC’s example is its view, rather than a binding legal decision.
Key takeaways
- A later hotel conversion can change an earlier SDLT result.
- In HMRC’s example, the trigger is the start of conversion work.
- The historic relief and rates must be checked against the original tax date.

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 supplied example does not state the tax date, so this page cannot confirm whether the historic multiple-home relief was available for a real purchase.
- Whether work has made flats unsuitable for use as homes can depend on what work began and when.
- The supplied facts do not explain why the higher rates apply or whether any buyer is not UK resident.
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 completion or other SDLT effective date
- The contracts and title showing the interest bought
- The tenancy agreements and their original terms
- A record of when conversion work actually started
- Plans, building contracts, invoices and site records
- Evidence of the property’s use before and after the work
- Details of every buyer and their UK residence status
