If you personally move to the the UK and no longer reside in South Africa then your personal taxes will be paid in the UK to the HMRC.
However the company in South Africa will still pay corporations tax in SA if it continues to be run in SA and earns income from SA. You could make the company a non-resident company given that you and your wife would be the directors, but not tax resident of South Africa and therefore your taxes as a result of dividends or directors fees may be taxed in the UK. Furthermore it can then be said that the company is not effectively managed in South Africa which changes quite a few things from a tax perspective. Are you planning on officially emigrating?
The basic principle though for paying taxes is that if earned in South Africa for the company then taxes will be paid on those earnings and similar to yourselves. If you are no longer resident of SA, but earning from an SA source there may be tax in SA, but your overall tax liability would be in the UK which means you would be allowed a tax credit against your overall liabilities in the UK.
