Deposit a non-whole number

It’d be good if we could deposit a non-whole number, e.g. £174.42, using an instant transfer method.

At the moment, the “amount” field will not allow a “.”

Currently I have £x pounds and .58p in my ISA account (due to a free share) and I would like to make a deposit of £x and .42p to bring it make to a whole number.

I understand why you wouldn’t want people depositing less than a pound, but for amounts over that, it should be fine, right?

When I was writing this, why could I not think of the word “decimal”? Non-whole number… Hahaha
