Holly Black: A reader this week asks, should I switch ISA provider? Short answer, probably yes. So, many people end up staying with the same company for insurance, banking and whatever else. And all that means is you usually end up with a bad deal. But there are three things to check first. One charges, will the new provider be cheaper? And will there be exit fees for leaving your current provider, it might not be worth doing if it's going to cost you. Second available investments, you need to make sure you're going to be able to access the things you want to invest in. Some providers only offer funds from certain firms, others might not offer ETFs for example. And third, check the new provider accepts transfers in from elsewhere. So if you still want to switch, just open the account with a new provider. Let them know you're switching. They do all the hard work for you. The whole thing should take around four weeks.
