The boost only has to be repaid on sale or at the very end of your mortgage term. You don’t have to make any boost repayments before then if you don’t want to.

But you'll have to choose from a family of New Build Boost mortgage rates while your boost is outstanding, and these may be higher rates you could get elsewhere.

You're liable for the full mortgage and boost, and if you don't make your contractual payments, we can take legal action including repossessing your home.
