Do your own research and dont rush into anything ... although if you are thinking of a tax wrapper, you only have a few days left to get some cash into an ISA (up to this years allowance). If you have money in an ISA you can then move it around into another investment once you have done some research at a later date.
Everone will have their own ideas when it comes to investment, but only you will know what level of risk you are willing to accept. The greater the risk .. the greater the reward .. or the greàter the loss. Putting money in a banks savings account is not investing, but buying shares within the tax wrapper of an ISA and keeping buying monthly through a saving scheme through good and bad times would prove a hard one to beat. As I said it's a risk reward thing and no one can advise you until you have sorted out what level of risk you are willing to accept along with over what period you are willing to invest.
Hargreaves Lansdown is my choice as their platform allows me total control over everything I need to do. Have a look at their website ... plenty advice on saving, investing and especially on risk and reward.
Remember do your own research, as I have found that even some IFA's are to be watched !
