Help to Buy: ISA at a glance

Saving to buy your first home can be a challenge, but now there’s a way you can get a helping hand.

With our new Help to Buy: ISA, when you purchase your first home the UK Government will pay you a bonus of 25% of your closing savings balance e.g. £50 for every £200. So you could get up to £3,000 towards your first home.

You can kick start your Help to Buy: ISA when you open it by putting in up to £1,200 in the first calendar month of funding. After that you can save a maximum of £200 a month.

What you should know
  • Available to first time buyers aged 16 or over who are UK residents and have never owned a residential property or any interest in land in or outside the UK.
  • Save up to £1,200 in the first calendar month of funding and then up to £200 per month thereafter. Please note that the later in the month you first fund the less time you will have to add further funds. E.g. – if you first fund with £200 on 30 May 2017, you only have until 31 May 2017 to add up to another £1,000.
  • Save in both a NatWest cash ISA and a NatWest Help to Buy: ISA in the same tax year providing between the two accounts you do not exceed the overall ISA allowance (£20,000 for 2017/2018). E.g. if you save £2,000 in you Help to Buy:ISA, the maximum you can save in your regular cash ISA is £18,000
  • The UK Government will pay a bonus of 25% of your closing savings balance. The minimum bonus is £400 on a closing balance of £1,600 and the maximum bonus is £3,000 on a closing balance of £12,000. E.g. - if you have a closing balance of £8,000, the UK Government will pay you a bonus of £2,000. The UK Government bonus is paid towards the completion of your first home and not at the deposit stage.
  • When you have found a property to purchase and received your mortgage offer there are four steps to complete to claim your bonus:
  1. Request to close your NatWest Help to Buy: ISA. You can do this in branch, over the phone or in writing.  Do not withdraw your savings before the account is closed as the bonus will be calculated on your closing balance.
  2. You will receive a Closing Document within 7 days of the account being closed.
  3. You must give your Closing Document to your conveyancer (i.e. solicitor) who will claim the 25% bonus from the UK Government. You have up to 12 months from closing your Help to Buy: ISA to claim your bonus but this should be done as soon as possible to make sure the bonus is received before you are due to complete the purchase of your new home.
  4. The bonus will be paid directly to your conveyancer, who will add it to your deposit and mortgage funds to make up the total purchase price of your new home.
  • The maximum property price a bonus will be paid on is £450,000 in London and £250,000 elsewhere in the UK.

Please note: You will need your National Insurance number during the application.
