Some schemes are specifically tailored towards buying a new build home, with different allowances when you buy in London. If you’ve already opened a London Help to Buy ISA, here you’ll find more information on what counts as London and how your ISA works.

How often can I pay into my Help to Buy ISA savings fund?

You can pay £200 each calendar month (up until 30 November 2029). In the first month, you can kick-start your savings by paying in an additional contribution of £1,000. If you were to withdraw money in the month, you are unable to replace it to top up your fund until the next calendar month.

What happens if I miss a Help to Buy ISA payment?

It’s OK to miss a contribution one month. You won’t be penalised, but you won’t benefit from the Government bonus contribution that month. You also won’t be able to double your payment to make it up the following month.
