B2B Contract - Consultant Income Taxable?

As a business registered in South Africa we have the opportunity to contract with a UK based company. This contract would involve consultants travelling from South Africa to territories where the UK Client conducts business, to support local teams. These would be for periods of 10 to 15 working days and would include support to the UK company in London from time to time. The South African company would invoice the UK based company, as per the agreement between the two entities, and the consultants would remain employed by the South African company, and their income taxed accordingly in South Africa. All consultants are South African and none are UK residents. What responsibility lies with the UK company in terms of declaring funds paid for these services rendered?

Hi NadiaGenis,
The responsabilty of what actions are taken by the UK based Company, lies with that company. We are not permitted to make comment on this matter.
Thank you.
