Agree that an ISA type wrapper is much needed here. However the UK ISA is far too generous, basically a bribe to wealthy middle aged and older voters. €5k or so limit p.a. much more sensible
I have moved to Australia and savings interest rates are much better. I get 3.5% interest before tax in an instant access account. The card I get with the account entitles me to 2% back on all transactions 100 dollars or less, and also there are no atm fees at any ATM. It's amazing. The banking apps are also so slick and convenient
