The government has created the Help to Buy ISA scheme to help hardworking people save towards their first home. First time buyers can save up to £200 a month towards their first home with a Help to Buy ISA and the government will boost their savings by 25%. That’s £50 government bonus for every £200 saved up to a maximum government bonus of £3,000. The bonus is available for home purchases up to £450,000 in London, and up to £250,000 outside London.
