Thank you for your reply.
If your income is not likely to exceed £15,000 pa initially, you are better off running your profession as a self employed sole trader.
All profits would be taxed at basic rate of 20% after your personal allowance.
If you were to trade as sole trader then you would also pay national insurance Class 2 (weekly flat rate) and Class 4 contributions (profits based).
Trading as LTD company, your profits would attract a Corporation Tax rate of 20%. Here again, draw a lower salary that woudl be covered by personal allowance and also have salary as a tax allowable expense in the company's accounts.
You could draw a lower salary (sufficient that you don't actually pay NI contributions but they count towards state pension contributions). More information on this can be found here
There is a lot that can be said but this is good starting point to consider. The rest can be classed as effective tax planning exercise. I will be happy to follow up when you are next in the UK as you visit every 2 months.
I hope this is helpful and answers your question.
