Best cash Isa rates this week

Everyone aged over 16 can save up to £15,240 in an Isa during the 2016/17 tax year.

The benefit of an Isa is that all the interest you earn is free of tax, which is why it should usually be your starting point for savings.

The personal savings allowance means basic rate taxpayers can earn £1,000 interest tax free without using their Isa, and people who pay the 40% rate can get £500.

However, wrapping your money in an Isa means you don't need to worry about a future tax bill because your savings have grown, or if better rates become available. 

The main reason not to use an Isa for your savings is if doing so will eat into the amount you could put into an investment Isa, where the tax relief could save you far more tax, as your investments are likely to grow faster.

Which type of cash Isa do you need?

When picking an Isa, the first thing to decide is whether you want to fix your interest rate or opt for more flexibility with a variable rate.

If you want to secure the interest rate you earn on your savings, and are happy to lock your money away for a set period of time, a fixed-rate Isa might be for you.

However, if you want to make additional deposits beyond the upfront opening deposit, or make withdrawals, then a variable-rate Isa with easy access is probably more suitable.

If you're looking for a savings account to save a deposit for your first property, you might be benefit from a Help to Buy Isa. See our top Help to Buy Isas guide.  

Remember, savings with UK banks are covered by the Financial Services Compensation Scheme (FSCS), so deposits up to £75,000 with any institution are protected by the UK government. If two banking brands (for example, NatWest and RBS) share a banking licence, the £75,000 guarantee is shared across the two brands.

All these savings accounts are covered by the FSCS unless otherwise specified. If your bank is licenced by another European country, savings up to €100,000 will be protected, but by the government where the bank is headquartered, rather than the UK authorities.

We look across as much of the of the savings market as possible to find the best deals using industry data from Defaqto.

All our picks are nationally available. We try and pick products that are available to both new and existing customers, but we’ll highlight some offers for existing customers if they’re much better than what else is on offer.

Unless rates are significantly higher than on other accounts, we avoid products that pay an initial bonus (which is normally a euphemism for a rate cut after 12 months), or those with tiered rates (these may not pay the advertised interest rate if your balance rises above or falls below a set amount).

All these savings accounts are covered by the FSCS unless otherwise specified. If your bank is licenced by another European country, savings up to €100,000 will be protected, but by the government where the bank is headquartered, rather than the UK authorities.

We will never include a savings account that isn’t covered by a European deposit protection scheme.
