Our verdict on each
Discovery Bank
Discovery Bank suits South African adults with a good credit record who want a personal loan or a revolving credit line from a direct lender, and it holds up well for anyone who plans to clear a loan early.
National Building Society
National Building Society suits borrowers who already bank with the society and want home finance and personal lending in one place. Its 50% maximum loan to value sits below what many rivals offer, so buyers needing a larger mortgage should compare elsewhere before applying.

Pros and cons
Discovery Bank
Pros
- Free early repayment: settling a personal loan early adds no charge, which is true of 81.2% of the listings.
- Lending runs ZAR 15,000 to ZAR 500,000, well past Monzo Flex at £10,000 to £35,000 and Cashspace ES at €100 to €5,000.
- A personal loan and a revolving credit line sit with the same lender (personal and credit line), so a staged home improvement draws only what the work needs.
Cons
- A variable rate leaves the final cost open until rates move, and the field leans the other way at 80.5%.
- The credit check is hard and the record needed is good, so a thin file has to clear a full assessment before an offer.
- The arrangement fee adds a monthly credit service fee on top of the once-off credit initiation fee, so a small balance still carries a monthly charge.
National Building Society
Pros
- Fixed periods of 5 to 25 give borrowers room to plan ahead
- Home improvement is listed as a use case, alongside purchase and equity release
- A direct lender, so applications go straight to the provider rather than a broker
Cons
- The 50% ceiling is low for a home purchase, and a 12 personal loan term is short
- Lending is listed as personal and secured, so debt consolidation and car finance sit outside the range
- Funding takes 5 working days on personal loans, longer than the quickest lenders compared here
Who each suits
Discovery Bank
Who it suits
- South African adults with a good credit record who can show a valid identity document, recent proof of residence and proof of income.
- Borrowers funding home improvements who want a revolving credit line for staged work as well as a personal loan.
- Homebuyers, since lending covers purchase, remortgage and first time buyer and a home loan runs to 100%.
Who should look elsewhere
- Anyone after a small one-off sum: Cashspace ES runs €100 to €5,000 and Cashspace runs PHP 500 to PHP 25,000, both far below ZAR 15,000 to ZAR 500,000.
- Borrowers who need a fixed rate to plan ahead: Discovery Bank is variable while 80.5% of the listings are fixed.
- Borrowers outside a single market: the bank is based in South Africa, so Monzo Flex at £10,000 to £35,000 suits a sterling customer better.
National Building Society
Who it suits
- Borrowers who keep their salary in an account with the society
- Home buyers who value a longer fixed period over a higher loan to value
- Members planning home improvement work
Who should look elsewhere
- Anyone borrowing the maximum the market offers, because 50% is capped low
- Applicants with income paid outside the society, since eligibility requires a National Building Society account
- Sofkredit, Creditilia ES and Prestalo followers, whose fixed periods of 0.5 to 20, 5 and 25 sit elsewhere in the market

Questions about each
Discovery Bank
Who regulates Discovery Bank, and does that protect the loan?+
Discovery Bank is authorised as an authorised financial services provider by the Financial Services Conduct Authority under FSP48657, and registered as a credit provider with the National Credit Regulator under NCRCP9997. Lending is direct, so the bank is the counterparty on the balance. Ask the bank directly what applies to a loan in good standing.
How quickly is a Discovery Bank personal loan funded?+
Money is released within 48 hours of the application being approved. Terms run 6 to 72 and the amount runs ZAR 15,000 to ZAR 500,000, so a home improvement can be covered in one draw once the paperwork is in. Applications ask for proof of income and recent proof of residence, which adds handling time before the clock starts.
National Building Society
What fixed periods can I choose?+
Fixed periods run 5 to 25, a spread of lengths for a purchase, an equity release or a home improvement plan. The upper end suits a borrower who wants the payment settled for years, while the shorter end keeps the rate commitment modest if plans change.
How much can I borrow against a home?+
The maximum loan to value is 50%, so you would fund a large share of the purchase price yourself. That suits buyers with a solid deposit or equity in an existing property. Anyone stretching further on the deposit would find a higher ceiling elsewhere.
