If you are not working here, either self or employed you do not need to pay SS. However you may have a problem with Double taxation as the income would be taxable in both countries. In order to pay only here you need to demonstrate to HRMC that you pay your taxes here, this is by fling returns and paying taxes, that would mean paying in both countries for a couple of years, and then claiming the tax back from the UK. The personal allowances are different UK allowances are for the UK only.
This i my understanding so I suggest you take professional advise for the complete answer.
