Hi Biddy,
Just to add more to Gordon's comment, There is a lot more that needs to be taken into account and a lot more information needed.
You refer to 'Best provider to invest with'. That can be interpreted a few ways.
Are they the best in regard to charges, do they offer the best returns. There are a lot of funds and providers out there so maybe if you are looking for advice it may be beneficial to find a Financial Advisor who is not a tied agent and is a Multi Agency advisor so that they have access to the different providers. Just to note There are some very good tied agents out there also and they may be accessing the great funds also but they can be limited to options.
The only advice that I feel I could give is to try and speak with a Financial Advisor direct. It is a bit cliched but there isn't one answer fits all.
Regards
David K
