Income Tax - where to pay it.

My French accountant deals with my TVA and income tax at present.

Now that the rules about TVA are changing from October, how easy it is to dispense with her services altogether and pay income tax soley in the UK. Even if it is a little more, I am sure I will be better off as I won't have to pay 2 accountants.

Will the French chase me for tax, or can I just ignore it and pay it all in the UK (that is if my UK accountant can't find a way for me to avoid it here )
