These new accounts to help first time buyers save for a deposit to buy their first home will be available from Autumn 2015. First time buyers over 16 will be able to open these special ISAs, make an initial deposit of up to £1,000 and then save up to £200 a month, and the Government will boost it by 25%. That’s a £50 bonus for every £200 saved, up to £3,000 in total topping up their £12,000 savings to £15,000.
