Pensions payments as a sole trader

I have an existing stakeholder pension scheme from when I was employed. However, I am now a sole trader and haven’t paid into it since going on my own. I want to (or rather feel I really ought to) start paying into it again. Does anyone know what the best way to do this is? Can I make my business pay half and me pay half? Does that work out more tax efficient? Or is there some other way I should do it? I want it to be as tax efficient as possible. thank you.

Hi - is nobody out there (accountant?) able to comment/assist with this query??

You may want to post something on UK Business Forums. They have quite an active number of accountants posting there.
