Best cash Isas 2021: Where to get the best cash Isa rates and deals

Our savings picks: This is Money’s five favourite best buy cash Isas – rates begin to nudge higher, but none beat inflation..


Our assistant editor Lee Boyce picks his five favourite cash Isas for savers in 2021 – essential reading to help you choose a top savings account for your money.

This top Isa round-up has keeping our readers updated on the best savings deals since 2014 – and is kept up-to-date throughout the year – bookmark it for the very latest developments.

How an Isa works and why you should have one

Each year in April, savers are given a fresh Isa allowance that qualifies for tax-free interest. 

For the 2021/22 financial year, starting 6 April 2021, the limit is £20,000.

Piggy five: We round-up the best tax-free deals – and it is slim pickings at the moment

You can transfer Isa money whichever way you wish between an investment account to savings account, whereas previously you could only shift it from saving to investments. 

Although cash Isas don’t currently offer fantastic rates, it is still worthwhile opening one to shield money away from the taxman.   

Isa rules state you can only contribute to one Isa per tax year.

You can also transfer an old Isa for better returns. Here’s a quick guide to Isa saving.

It is possible to switch your current year’s cash Isa if you move the entire amount, but it is far simpler to get your choice right in the first place.

Rates are low and that makes the best Isa more important

Banks and building societies should be apologising to savers for the slim pickings on offer here. 

The best buy easy-access rate on a tax-free account has plunged under 1 per cent for the first time while no major bank comes close to featuring on the list. 

It also comes at a time as inflation races higher, leaving all savers with a serious headache.

Savings rates really are dire at the moment and unfortunately, institutions are doing little to shelter savers from the assault of the low interest rate environment.

The coronavirus crisis cut to 0.1 per cent for the base rate, launch of a new funding scheme to pump cheap money to banks, and expansion of quantitative easing, has made things even worse. 

Many now ask themselves why bother?

Yet when rates are low it becomes even more important to make sure you are getting as much as you can from your savings. 

We also think an Isa is still worth having, despite the new tax-free savings interest allowance of £1,000 a year for basic rate taxpayers and £500 for higher rate taxpayers. 

It’s tough to get that much interest now, but one day rates will rise. 

Money sheltered in an Isa will deliver a tax-free income, even above that £1,000 level and if you are building up a long-term pot, you may one day be very grateful for that.

And who knows if the personal savings allowance will be around forever – it is much more likely to disappear than the Isa wrapper.
