Key Features

An ISA is an individual savings account. The main difference between this and other forms of savings accounts is that the interest you earn with an ISA is tax-free, whereas you may have to pay tax on other savings accounts.

Unlike a standard savings account you may have with your Bank or Building Society, an ISA allows you to save or invest up to a set amount (your ISA allowance) each tax year without having to pay tax on interest, dividends, or gains.

You get a new ISA allowance every year, which is set by the UK Government. The ISA allowance for the current tax year is £20,000. The tax year runs from April 6th to April 5th.

  • There are several different types of ISAs, each one designed for a particular kind of saving or investing.
  • The various types of ISA available include Cash, Stocks and shares, Innovative finance, lifetime and junior.
  • New rules were introduced on 6th April 2024, you can now open as many ISAs as you want in a tax year. However, you still have the same ISA allowance of £20,000 across these accounts.
  • ISA allowances can’t be carried over from one tax year to the next, so if you don’t pay in your full allowance before April 5th, you’ll lose the rest of that year’s allowance.
  • Anything you save into an ISA after April 5th will be counted as part of your ISA allowance for the new tax year. Use it, don’t lose it.

*AER stands for annual equivalent rate and illustrates what the rate would be if interest was paid and compounded once a year. Your tax treatment will depend on your individual circumstances and may be subject to change in the future. The rate of interest payable on variable rate accounts may be subject to change in the future.

Helpful staff made for a pleasant experience. The account I wanted, which had one of the best interest rates I could find, was easily set up when I called into Harpenden branch. Tabitha was most helpful and it was a relaxed experience in pleasant surroundings.
