Best Online Savings Accounts

So many banks and building societies now use web based banking that it is difficult to know which provider is offering the best online savings account. The main advantage of an online savings account is the access, but there are other benefits too:

Can open online for a little as £1
Accessible 24 hours a day
Allow payments, transfers and withdrawals at any time, online, with no notice period
Offer a good rate of AER
Should link to other accounts you hold
Offer secure online banking

Online savings accounts are generally instant access, which means the AER may be slightly lower than with a bond or notice period account, but there are still some very competitive deals on the market so it is worth shopping around.
