Understanding the 5% Surcharge

What is it?

Since April 2025, if you buy an additional property (second home, holiday home, or buy-to-let), you pay an extra 5% on top of the standard stamp duty rates. This applies to the entire purchase price.

When does it apply?

The surcharge applies when you already own another residential property anywhere in the world at the end of the day of purchase, and the new property costs £40,000 or more.
