Zilch Boost lets you pay for a purchase that costs more than your available credit. Boost adds the difference between your available credit and your purchase value to your first instalment.

For example, if your available credit is £200 but you want to make a £300 purchase, we'll just add the extra £100 to your first instalment and you'll pay the rest in your usual three remaining instalments.

You must have enough in your bank account to cover your first instalment + the extra Boost amount or your purchase will be declined.
