What is the best Coventry Fixed Rate ISA?
A Fixed Rate ISA is a type of savings account where your money is locked away for a set period, and in return, you get a guaranteed interest rate. Your interest will also be tax-free, but you won’t be able to withdraw your money until the end of your fixed term (usually between one to five years).
In this guide, we’ll cover all the Fixed Rate ISAs currently offered by Coventry Building Society. If you’re looking for the best Fixed Rate ISA on the market, keep in mind that the familiar high-street banks don’t always offer the most competitive rates.
Withdrawing funds before maturity will incur a charge. Partial withdrawals from a Fixed Rate ISA are restricted. Tax treatment depends on individual circumstances and may be subject to change in the future

Currently, Coventry Building Society is offering three Fixed Rate ISAs, with rates ranging from 3.65% to 3.80% AER (fixed).

After all, the big high street banks and building societies don’t always offer the best rates and you may find a more competitive ISA with a different provider.

How to find the best Fixed ISA Rates
There are hundreds of Fixed Rate ISAs to choose from across a range of banks, building societies and modern app-based providers. Opening an ISA with a high street bank might seem like the easiest option, especially if you already have a current or savings account with them. This could see you missing out on a better interest rate, as the biggest banks don’t always offer the best rates.
By choosing an ISA with a competitive interest rate, you can reach your savings goals faster and reduce the impact of inflation. And, with a fixed rate account, you’ll protect your savings from falling interest rates too!
Although the interest rate is important, it’s a good idea to look for excellent customer service and an easy-to-use savings app too. That way, you should find it easier to save money and stay on track.
