South African licences are on DVLA's designated-country exchange list, so the exchange route applies. The official outcome states:
"You can continue to drive in the UK without exchanging your licence for 12 months after becoming resident."
"After 12 months you must exchange your licence to keep driving. You can exchange it up to 5 years after becoming resident, if it has not expired."
Old-format licences: "You can no longer drive in the UK with an old South African book of life-style licence or letter of entitlement to one, and you cannot exchange these for a UK licence. You must have a new credit-card style licence or a letter of entitlement to one."
The exchange route also asks you to email the Road Traffic Management Corporation (RTMC) for a "Confirmation of South African Driving Licence" letter first.
Wording from GOV.UK, Exchange a foreign driving licence, the South African outcome page, checked 22 July 2026. Exchange uses a D1 form from a Post Office that offers DVLA services, with a £43 fee.
