How to send money to the UK from South Africa: What to know before you transfer

Key insights: Sending money from South Africa to the UK 

• Compare exchange rates, not just transfer fees. When sending money from South Africa to the UK, the banks’ hidden GBP/ZAR spread can have a greater impact on the total cost than the advertised transaction fee, particularly on larger transfers.
• South African residents aged 18 or older currently have a R2 million Single Discretionary Allowance (SDA) per calendar year (doubled from R1 million on 8 April 2026), shared across qualifying offshore transactions.
• Larger transfers may require an Approval of International Transfer (AIT) from SARS, along with supporting documents confirming the source and purpose of the funds.
• If you're transferring money from South Africa to the UK to cover a fixed payment in pounds, changes in the GBP/ZAR exchange rate can significantly affect the Rand amount you need.
• If you're buying property in the UK, account for additional expenses such as the 2% stamp duty surcharge that may apply to non-UK residents in England and Northern Ireland, as well as the property price and transfer costs.

Whether you’re buying UK property, moving savings after emigration or investing offshore, there are several factors to consider when transferring money from South Africa to the UK. On a R3 million transfer, a 2% difference in the exchange rate equates to R60,000, while delays in obtaining the necessary SARS approvals can affect payments with fixed deadlines.

These transfers are increasingly relevant to South Africans living and investing abroad. According to the 2026 South African Diaspora Report, more than a million South Africans now live overseas, with over half of them based in the UK, Australia and the US.

For larger South Africa to UK money transfers, the exchange rate is only one part of the equation. Your available foreign exchange allowances, SARS requirements, supporting documentation and payment deadlines can all affect how much you need to send and when the funds will arrive. Understanding these factors upfront can help you plan your transfer and avoid unnecessary costs or delays.

Understand which offshore allowance applies to you

Since 8 April 2026, South African resident individuals aged 18 and older have been eligible for a R2 million Single Discretionary Allowance (SDA) per calendar year for qualifying offshore transactions, double the previous R1 million limit. Importantly, this is not a dedicated allowance for sending money to the UK. Travel expenses, qualifying foreign card transactions, gifts, investments and other permitted payments all draw on the same annual allowance.

For larger capital transfers, residents may generally access a further R10 million Foreign Investment Allowance (FIA) after obtaining an Approval of International Transfer (AIT) from SARS, and transfers exceeding the applicable limits may require additional approval from the South African Reserve Bank’s Financial Surveillance Department. SARS can take up to 21 working days to approve AIT applications, so it’s worth starting the process well ahead of your payment deadline.

Your allowance route also depends on your tax-residency status. If you’ve formally ceased to be a South African tax resident, the requirements for transferring funds offshore may differ from those that apply to a South African tax resident who is temporarily living in the UK. Establishing your status and the applicable requirements before initiating a large transfer can help prevent unnecessary delays.

If your transfer forms part of a broader relocation to the UK, our tax emigration service can help you navigate the relevant tax and documentation requirements.

Why the purpose of your UK transfer matters

The reason for your transfer to the UK helps determine which exchange control rules and supporting documents apply. Common reasons to send money from South Africa to the UK include:

• Purchasing or maintaining UK property
• Moving savings after emigration
• Funding relocation expenses
• Making offshore investments
• Supporting family members
• Paying university or education costs
• Paying professional or legal costs

Every international payment must be reported under the correct Balance of Payments (BoP) category. Depending on the transaction, you may need supporting documents such as a property sale agreement, investment statements or proof of the source of funds. Different types of transfers also require different considerations:

Purchasing or maintaining UK property: Your deposit and completion funds will typically need to reach your UK conveyancer by a specified deadline. Arrange your international money transfer well in advance of exchanging contracts to allow time for exchange rate planning, documentation and processing.

For non-UK residents purchasing residential property in England or Northern Ireland, a 2% Stamp Duty Land Tax (SDLT) surcharge generally applies on top of the standard rates. A further 5% additional-property surcharge may also apply if the purchase falls under the additional-property rules, including where you already own a home in South Africa.

Moving savings after emigration: If you’ve formally ceased South African tax residency, the process for transferring savings offshore may differ from that applicable to South African tax residents. The usual R2 million Single Discretionary Allowance (SDA) and R10 million Foreign Investment Allowance (FIA) limits don’t apply in the same way, and the transfer may be treated as a capital transfer, subject to source-of-funds verification and the relevant requirements.

It’s worth noting that ceasing your South African tax residency can also trigger exit tax, with certain assets deemed to have been disposed of for Capital Gains Tax (CGT) purposes. Given the potential tax implications, seek professional advice on the timing of your emigration and any associated asset transfers before formally ending your South African tax residency.

Funding relocation expenses: Relocating to the UK often involves moving a lump sum of money, particularly if you’re using proceeds from the sale of your South African home to cover a property deposit, school fees and other initial set-up costs before your first UK salary arrives. Planning and staging these transfers around your move can give you greater control over your currency conversion and help you manage the timing of your funds more strategically.

Making offshore investments: Funding a UK brokerage account or investment platform will typically involve your SDA, while larger transfers may use the FIA, subject to the relevant requirements and SARS approval through an AIT. Start the process early, as delays in obtaining approval or preparing supporting documents could mean missing an investment window.

Compare the exchange rate, not just the transfer fee

When you transfer money from South Africa to the UK, a low transaction fee doesn't necessarily mean a low-cost transfer. Many providers, including most banks, build a hidden 2-3% margin into their exchange rates. This spread between the market rate and the rate you actually receive can add significantly to the cost of your transfer, even when no separate fee appears on the invoice.

GBP/ZAR traded at around R21.77 in late September 2026. At that rate, £50,000 costs roughly R1.09 million at the market rate, but a hidden 2.5% exchange rate margin adds approximately R27,000 to the Rand cost. That’s why it’s important to assess the total cost of the transaction, including the exchange rate, spread and any additional transfer fees.

Don’t leave the currency conversion until the payment deadline

Imagine you've agreed to pay £100,000 towards a UK property purchase. While the amount due in Pounds is fixed, the Rand required to buy those Pounds can change with the GBP/ZAR exchange rate. Waiting until your conveyancer's deadline means accepting the rate available on the day, potentially increasing the cost of your transfer. Depending on your circumstances and timeframe, you may be able to plan your currency conversion in advance, secure an exchange rate using a Forward Exchange Contract (FEC), or transfer funds in stages.
