The Help to Buy ISA is a government-backed savings account designed to assist first-time homebuyers in the United Kingdom. It allows individuals to save up to £200 each month, with the government providing a bonus of 25% on savings, up to a maximum of £3,000. This means that for every £200 saved, the government adds an extra £50. To qualify for the Help to Buy ISA, you must be a first-time buyer aged 16 or over. The account can be opened with an initial deposit of £1,000, and the bonus can be claimed when purchasing a home valued up to £450,000 in London or £250,000 elsewhere in the UK.
