Help to Buy Isa - first-time buyers

If you're saving for your first home, you can now open a Help to Buy Isa, which is designed to help first-time buyers get onto the property ladder.

You can deposit up to £200 a month in a Help To Buy Isa (plus an additional initial deposit of £1,000), with the government topping up these savings by 25% up to a maximum of £3,000.

Your Help To Buy Isa savings can be used to buy a home worth up to £250,000, or £450,000 in London. And if you're buying with someone else, you can open separate accounts and jointly earn a bonus of up to £6,000.

Virgin Money's Help to Buy Isa currently offers the best deal, paying 3% AER. 

You can't contribute to a cash Isa in the same tax year as a Help to Buy Isa, so if you want to open a Help to Buy Isa in 2016-17, make sure you don't deposit new funds into another cash Isa in this tax year.   

The Which? Money Compare tables let you search hundreds of savings accounts and cash Isa deals from providers large and small so that you can find a good home for your nest egg. We also combine this with our unique customer scores that show you how well the providers featured are likely to treat you in the long run.
