A free website – at www.savingschampion.co.uk – that tracks the interest rates paid on bank and building society savings accounts.
Add details of savings accounts and you'll be emailed if there are rate changes and told if there are better deals around. There's also a rate alert you can sign up to which emails you when there are interesting new deals around.
If you're not online you can't use the Rate Alert.
This is a great free service which could ensure you don't get stuck in a useless account paying 0.1 per cent or worse. The site is hoping to widen the net this year, to include interest-paying current accounts for instance. However, we could do with a similar site for other financial products.
