The 28-Day Rule: Proving South African Funds for a UK Visa

Key takeaways

• The 28-day rule requires visa maintenance funds to be held continuously for 28 consecutive days, with the balance never dipping below the required amount on any single day (as of July 2026).
• The 28 days are counted back from the closing balance on your most recent statement, and that closing balance must be dated no more than 31 days before you submit your online application.
• Funds in rand are converted to pounds using the OANDA spot rate on the date of application, so a rand-denominated balance needs headroom against currency movement.
• Student route applicants can rely on a parent's account; Skilled Worker maintenance funds must be held by the applicant or their partner.
• A large deposit landing mid-window restarts the 28 days, which is why the South African transfer must be planned before the visa timeline, not alongside it.

What the 28-day rule requires

The 28-day rule is the UK Home Office requirement that visa maintenance funds be held at or above the required level for 28 consecutive days before the application. It applies where a route requires funds "as specified in Appendix Finance" of the Immigration Rules, which in practice covers the Student route, Skilled Worker maintenance and several other work and study routes. Two clocks run together:

• The 28-day holding period. The balance must not fall below the required amount on any day in the window. Even a one-day dip, for a small direct debit, fails the test.
• The 31-day freshness limit. The 28 days are counted back from the closing balance on the most recent statement you provide, and that closing balance must be no more than 31 days old on the date you submit the online application.

The Home Office sets this out in its guidance on financial evidence for student applicants and financial evidence for sponsored work routes. Caseworkers apply the rule mechanically, with essentially no discretion.

The rule does not apply to the spouse and partner route, which runs under Appendix FM and uses a six-month evidential period for cash savings instead. We cover that separately in our spouse visa financial requirement guide.

Why moving money resets the clock

A qualifying 28-day window needs a continuous, evidenced balance, so a large deposit arriving mid-window means the full amount has only been held from the deposit date. If R500,000 lands in the account on day 14, the 28 days effectively restart from day 14. This is the single most important planning point for South African applicants, because the money usually has to make two moves before it is ever counted:

1. Out of South Africa. For typical maintenance amounts, this runs under the R2 million Single Discretionary Allowance, which requires no SARS pre-approval (the SDA was doubled to R2 million in the 2026 Budget). Our money transfers service handles this leg at bank-beating rates, with the bank's flat R250 SWIFT fee the only transfer cost.
2. Into the account that will be evidenced. Whether that is a UK account or stays in a South African account (see below), the 28-day clock only starts once the full required amount is sitting in the account named in the evidence.

Work backwards from your intended application date: 28 days of holding, plus up to 31 days of statement validity, plus the transfer itself, plus contingency. Two months of genuine lead time is the realistic floor; starting the South African transfer after booking a visa appointment is how applications end up rushed or refused.

Can the funds stay in a South African account?

Funds held in a South African bank account can qualify, provided the account and evidence meet the Home Office's conditions. The requirements that matter most for SA-held funds (as of July 2026):

• The bank must be regulated by the appropriate regulatory body for the country it operates in, use electronic record keeping, and be verifiable by UK Visas and Immigration. Major South African banks meet this.
• The funds must be immediately accessible cash. Fixed deposits with withdrawal restrictions, investment accounts, shares and pension funds do not count.
• Statements must show the account holder's name, the account number, the bank's details, and the balance across the full 28-day period.
• Foreign currency balances are converted to pounds at the OANDA spot rate on the date of application.

That last point deserves respect. A rand balance that sits exactly at the required threshold can fall below it in pound terms purely because the conversion is done on a date you do not control. The practical answer is headroom: hold comfortably more than the requirement, or convert to pounds before the evidential window starts so the number is fixed in the currency the Home Office measures.

Whose account, and what paperwork travels with the money

Who can hold the funds differs by route (as of July 2026). For the Student route, funds may be held by the applicant or a parent or legal guardian, with the relationship evidenced. For Skilled Worker maintenance, the funds must be held by the applicant or their partner; parents' accounts do not qualify. Route-specific amounts and exemptions are covered in our spoke guides for each visa: our complete guide to proving and funding your UK visa links them all.

South African applicants also carry a second documentation trail that UK-focused guides ignore: the SA side. The Home Office wants to see the funds were lawfully acquired, and the same source-of-funds paperwork that satisfies a South African bank processing the transfer under the SDA (sale agreements, salary records, gift letters) is exactly what answers a UKVI query about a large recent deposit. Keeping the SARS and bank paperwork from the transfer leg filed alongside the visa evidence closes both loops at once.

The pattern we see repeatedly: the visa timeline gets planned in detail and the money is treated as an afterthought. Then the transfer lands mid-window, the 28 days restart, and a course start date or job start date is suddenly at risk. When clients tell us at the first conversation that the transfer is for a visa application, we plan the transfer date against the evidential window from day one. That single piece of sequencing removes most of the risk.

Frequently asked questions

What is the 28-day rule for UK visas? The 28-day rule requires maintenance funds to be held continuously at or above the required amount for 28 consecutive days, ending no more than 31 days before the visa application is submitted. It applies to routes governed by Appendix Finance, including the Student and Skilled Worker routes.

Does the balance really fail if it dips for one day? Yes. If the balance falls below the required amount on any single day in the 28-day window, the requirement is not met and the application can be refused. Caseworkers check every line of the statement.

Can I use money in a South African bank account for my UK visa? Yes, provided the bank is properly regulated, keeps electronic records, and the funds are immediately accessible cash. Rand balances are converted to pounds at the OANDA spot rate on the application date, so hold headroom above the threshold.

What happens if money is transferred into my account during the 28 days? A deposit that is needed to reach the required amount restarts the 28-day clock from the date it lands. Complete all transfers before the evidential window begins.

Do my parents' bank statements count? For the Student route, yes, with evidence of the relationship. For Skilled Worker maintenance, no: the funds must be held by the applicant or their partner.
