The rates of fixed-term savings bonds continue to creep upwards, with the most competitive accounts now all offering an annual interest rate of over 2pc.
Competition is being driven by a number of small, online only banks which savers may not be familiar with.
Check if the providers are covered by the Financial Compensation Services Scheme, which protects up to £85,000. Some European banks which "passport", meaning they have a UK division, may subscribe to a similar scheme in their home country. If it goes bust, you may face exchange rate and language issues and it may take longer to get your money back.
By tying up funds in fixed savings bonds, customers can guarantee the rate for the term and protect themselves against future cuts.
Savers who have used up their cash Isa subscription for this tax year (£20,000), and want to deposit any extra savings into fixed-rate bonds or easy-access savings accounts, should read this guide (which will be updated as deals change) to find out the best rates on offer.
