Hi leoden47,
As conmankiller suggests, you could start by comparing a range of products and rates using our comparison tool.
The length of time you can 'lock' away your money will help to determine the rates available to you. And even after you've decided, it's still well worth keeping an eye on the rate of return and comparing it to what else is currently available.
Also bear in mind the security of your savings. The Financial Services Compensation Scheme (FSCS) in the UK covers an individual for up to £50k worth of savings (£100k for a joint account). However, that protection applies per banking institution, not per account. If you have more than £50k with any one bank or building society it is worth spreading your money around between different providers. Take a look at Clare Francis's article 'Who owns who?' for more information. Off the top of my head, I'm fairly sure deposits by small clubs are treated in the same way as individual accounts - but I'll double check and let you know as soon as I can find out.
I hope that helps. Do let us know what you decide to do and how you get on. I'm sure our other community members can also offer their thoughts and opinions on the important things to consider.
