Cash Isa deals of the week

Find out which accounts pay the best rates

Discover the best cash Isa deals currently available with the Which? Money roundup.

Each year, you can deposit your savings into a cash or stocks and shares Isa, or both. The overall limit for the 2016-17 tax year for both cash and stocks and shares Isas is £15,240.

Here, we take a look at some of the best cash Isa rates on the market. We have excluded Isas with certain qualifying conditions and restrictions on withdrawals.

If you’re keen to find out more about any of these deals we’ve also included links to Which? Money Compare, the comparison site which lets you see banks’ customer scores as well as their rates, and where you’ll find more details about each Isa.

No cash Isas can beat inflation

At the moment, you can find better savings rates on non-Isas. In fact there are no cash Isas on the market that pay enough to beat the current rate of inflation (1.8%).

To ensure your money doesn’t lose value in real terms you’ll need to be prepared to tie up your money for at least three years in an ordinary fixed-rate savings account.

Best instant-access cash Isa

The top rate meeting our criteria is offered by NS&I, which is paying 1% AER on its Direct Isa. However, NS&I has announced that it will be cutting this rate to 0.75% as of 1 May 2017.

You can open the NS&I cash Isa with as little as £1.

Mansfield Building Society and Saga offer the next best rates in our table, both at 0.95% AER.

Best notice cash Isa

Notice cash Isa accounts used to pay a higher rate than instant-access Isas, but at the moment this isn’t the case.

Help to Buy Isa – first-time buyers

If you’re saving for your first home, you can 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 when you buy a home.

Your Help To Buy Isa savings can be used to buy a property 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.

Barclays currently offers the best instant-access deal, paying 2.27% 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 providers are likely to treat you in the long run.
