rovsoup, Why do you wan to go agency? There are a number of problems going on in the agency work at the moment with reference to the tax position. If you live in the UK it looks like you will no longer be able to work as self-employed. Agency PAYE is a bum deal as you have to pay the 12.8% employers national insurance liability out of your day rate so as the agency can continue to make its profit. You have no benefits, pension or income if itβs quiet. Not to mention health cover for being sick.
There are good points for going agency especially if you only want to work say 100 days or so but with loss of the self employed status it all seems hardly worth it to remain agency if you live in the UK. I would advise you to have a think about why you want to change.
