At Compare the Market we compare cash ISA savings accounts from a wide range of providers – big banks and building societies, and smaller providers you might not have heard of. You can compare interest rates all in one place and find ways to help your savings grow.
ISAs explained in 20 seconds
- ISAs are tax-free accounts for your savings or investments.
- When your money is in an ISA, you don’t pay tax on any interest you earn.
- Each year, the Government sets an ISA allowance, the maximum amount you can save tax-free.
- Your ISA allowance resets every new tax year (6 April-5 April).
- If you don’t use your allowance, you lose it.
Which ISA providers do we compare?
Several types of ISA are available, including cash ISAs, stocks and shares ISAs, Help to Buy ISAs and Junior ISAs. You can compare cash ISAs (instant and fixed) and Help to Buy ISAs with Compare the Market.
We work with most of the UK's top ISA providers to find you great deals. Our searches don't include every single provider in the market – a very small number opt out of all comparison sites and others do not meet the strict partner criteria we use to protect our customers.
Compare cash ISAs using our comparison tables
You can see and compare offers in our comparison tables. The tables show rates of interest and are a way to find providers that offer all the features you want from your ISA.
