ISAs are some of the best savings vehicles you can use in the UK as they allow for up to £20,000 of tax-free savings a year.

However, speculation about changes to ISA rules have made headlines recently, after chancellor Rachel Reeves was lobbied to reduce the maximum annual limit to £4,000 for cash ISAs.

Even if this policy were to be imposed, it would not detract from the fact that putting your money into an ISA can be one of the most tax-efficient ways to save your money.
