Which? rounds-up the best online cash Isa deals on the market to help you invest your tax-free allowance for 2015/2016.
Online instant-access and fixed-rate cash Isas
Over the years, online banking has become increasingly popular due to convenience and more importantly, competitive interest rates.
The majority of accounts sitting within the top section of our instant-access and fixed-rate Isa tables must be managed online, or in some cases, offer this method as an option.
At the moment, Punjab National Bank dominates the top spot in all categories, however you won’t be able to manage these accounts via the internet as in-branch or postal access are the only options.
Here, we take a look at some of the best online cash Isa rates on the market. If you’re keen to find out more about any of the deals, we’ve also included links to Which? Money Compare, where you’ll find more details about each Isa.
