The new tax year may only just have begun, but there's no excuse not to find a home for your ISA allowance as soon as possible.
ISAs have become the UK's savings weapon of choice since they were launched in 1999, with only the reach of the current account more widespread amongst UK consumers when it comes to personal finance.

"Savers investing now are being offered a host of competitive rates, some as high as 5.00%, but they need to act fast as the best deals won't last for long."
