If you’re buying a second home in the UK, you’ve likely come across the extra 5% stamp duty land tax (SDLT) that applies to additional properties. It’s a major cost consideration and often a frustrating surprise for buyers who may already be stretching their budgets.
At London Stays, we know that finding the perfect second property—whether for family, investment, or holiday use—is only part of the journey. The real headaches often start when navigating complex taxes like SDLT. That’s why we’ve put together this clear, human-focused guide to help you make confident decisions and avoid costly pitfalls.
What is the 5% Stamp Duty Land Tax on Second Homes?
When purchasing an additional residential property in England or Northern Ireland (not your main residence), you’ll usually pay a 3% surcharge on top of the standard SDLT rates. For properties worth between £250,001 and £925,000, that means the rate jumps to 8% total, but 5% of this is the base SDLT rate in this band—hence the common reference to the “5% stamp duty land tax”.
This rule came into effect in April 2016, aimed at curbing property investment pressures in overheated housing markets.
Who Is Required to Pay the Higher SDLT?
The only time you become liable for paying the higher rate is when:
You already own a home anywhere in the world except that you are not replacing your main residence.
Coupling and civil partnership are equated; thus, one of you can own an existing property: both members are regarded as a unit. If one partner already owns a home and the other buys a property, a surcharge applies.
How to Escape the 5% SDLT on Second Homes?
The surcharge will not apply in certain circumstances. These include:
Replacing your main residence: sell your main residence and buy another one within three years to claim a refund.
Inherited property: if you have inherited a share of another property below 50 percent, then you qualify for exemption.
Mixed-use properties: if your second home becomes partially commercial (with, say, a shop or office), the surcharge may not apply.
Always best practise to double-check with a qualified solicitor or conveyancer.

Q. What about Buy-to-Let landlords?
However, the 3% surcharge will apply when the intention is to rent, even in the event of buying. Tax reliefs available on mortgage interest and other expenditures may provide some balance to the overall investment strategy. MoneySavingExpert and Which? usually provide the latest updates on landlord-specific breakdowns.
Q. Who has to pay the higher stamp duty?
If you own any home practically anywhere in the world, in buying another one, you will most likely pay the higher SDLT rates for having not sold your current main residence.
Important:
Married couples and civil partners are considered one unit. The 3% surcharge applies even if only one of you owns another property.
Q. Are any second-home purchases exempt from the surcharge?
Yes, there are a handful of cases:
- You’re replacing your main home and sell the previous one within 3 years.
- You inherit a share of a property under 50% (this usually doesn’t trigger the surcharge).
- Your property is mixed-use (like a flat above a shop), which falls under non-residential rates.
You can apply for a refund on the extra stamp duty that you may have paid. This can be done when you pay the higher tax rate but sell your former main residence within 3 years.
Suppose you buy a new property before selling your old one after a long delay, in which case you will need to pay the higher SDLT while you wait to sell the old home. After doing so, you can submit a refund request to HMRC.

Q. Is the 5% SDLT applied to buy-to-let properties?
Yes, all buy-to-let properties are included in the surcharge. This surcharge applies to all properties that are classified as additional properties, unless they fall under an exemption from a special rule.
That said, some tax reliefs and deductions are still applicable for landlords, which can help settle at least part of the costs incurred. Always consult a financial advisor.

Q. What if I am purchasing a property with someone else?
If at least one of the two buyers has a property already, then both pay the higher rate of SDLT. It will apply even if your partner is a first-time buyer.
Q. I own a house abroad. Will this make me pay the 5% SDLT here?
Yes, even if you own a single home elsewhere outside the UK, you will pay the higher rate when you are purchasing in the UK. HMRC counts property ownership worldwide to impose the surcharge.
Q. Are holiday lets and second homes covered in the same act?
Generally speaking, yes. They qualify as a second property and the additional charge applies whether it is a weekend cottage or an apartment in the city, utilised occasionally.
Q: What are the procedures for the refund?
A: Application for the refund can either be made online, or one can fill out the HM Revenue and Customs’ repayment request forms, print it, and send it to HM Revenue and Customs.
Applications are transferred from the previous 10 months to now being 12 months after the date of sale.
HMRC denies late applications.
Q: How long does it take the stamp duty surcharge refund to process?
HMRC aims to process all refunds within 15 working days of the date they are received, but on occasion, refunds have taken up to fifty-five working days. (HMRC said at a recent meeting that they were now doing more than ninety per cent of refund applications within fifteen working days.)
Payment will be made via BACS transfer if your application is successful.
Q. But what if I purchase in Scotland or Wales?
It is a different kettle of fish:
- Scotland : Additional Dwelling Supplement (ADS).
- Wales : Higher Rates for Additional Dwellings (HRAD).
Conclusion
Although stamp-duty tax is at times seen rather as a hindrance on the way to the purchase of property, understanding the application of the 5% stamp duty land tax on second homes does offer financial leverage. It gives room in budgeting, provides grounds for smart negotiations, and prevents nasty surprises on completion day.
