Santander's student account advertises an interest-free overdraft of £1,500, yet the limit on the day you open it is £250. The larger figure arrives only after you register for online banking and pay in £500, and Santander then expects at least £500 to go in every four months. That gap between the shop-window number and the day-one number is the most useful thing to check on any student account, and in the first week of October it is worth checking quickly, because two of the offer windows close before the end of the month.
Most freshers are settled in by now, and the case for choosing an account on its overdraft rather than its welcome gift has been made repeatedly since the summer. The Guardian's 18 August round-up quoted Moneyfactscompare saying that an interest-free overdraft can be worth more over a degree than a one-off freebie, and Save the Student's banking expert Tom Allingham put the pressure in numbers: maintenance loans now fall short of living costs by an average of £502 a month. Both points hold up. The figures below come from the banks' own product pages as they stood on 3 October 2026, with the Guardian piece as a cross-check, and they add the parts the headlines skip: starting limits, deadlines, exclusions and what happens once you graduate. Every limit is an "up to" figure, which means it depends on a credit check and on how you run the account.
The overdraft ladder, bank by bank
| Bank | Starting limit | Where it climbs to | The catch |
|---|---|---|---|
| NatWest / RBS | Up to £500 | Up to £2,000 from the second term of year one; up to £3,250 from year three | Must be your main account, with student finance or other income paid in |
| HSBC | Up to £1,000 | Up to £2,000 in year two; up to £3,000 in year three | Increases depend on status and how you have run the account |
| Nationwide FlexStudent | Up to £1,000 | Up to £2,000 in year two; up to £3,000 in year three | Needs £500 paid in each term, or £1,500 over the past year in two or more payments |
| Lloyds | Up to £1,500 | Up to £2,000 in years four to six | The limit you are offered depends on your circumstances |
| Santander Edge | £250 until conditions are met | £1,500 in years one to three; £1,800 in year four; £2,000 in year five | Online banking registration, then £500 paid in and £500 every four months |
| TSB | Up to £500 | Up to £1,000 from month seven; up to £1,500 from month ten | Approval needed at each step |
Read across the rows and the headline numbers mislead in both directions. NatWest's £3,250 is the biggest interest-free limit on the market according to the Moneyfacts figures the bank cites, correct at 30 June 2026, but a first-year student gets £500 on day one and has to wait for the second term to reach £2,000. HSBC and Nationwide offer £1,000 from the start, which suits a first term in which a deposit, the first month's rent and a kitchen shop all land together. Lloyds is the plainest of the six, with £1,500 from the outset and barely a ladder to climb. Santander's table looks similar at £1,500 for years one to three, but the £250 starting limit means the money you may actually need in October is not there until you have registered and paid in £500. TSB asks for the most patience, with £500 for six months, £1,000 from month seven and £1,500 from month ten, and offers 5.00% AER (variable) on balances up to £500 as the consolation. For a first term with heavy upfront costs, HSBC or Nationwide is the better pick; if you expect to be borrowing in year three, NatWest's ceiling wins.
Freshers offers still open, and the dates that matter
- Santander Edge: a free four-year 16-25 Railcard, which Santander values at £115, plus a prize draw for anyone who opens or transfers an account between 14 July and 16 October 2026 and makes a debit card purchase by 31 December. Santander's draw terms say everyone who enters wins at least £20.
- Lloyds: £100 cash for opening a Student Account, or converting an existing Lloyds account, between 30 July and 30 October 2026 and paying in at least £500 by 30 October. The £500 can include your student loan. Up to £120 of Deliveroo vouchers follow at £20 for each month from November to April in which you make 20 or more qualifying debit card transactions.
- Nationwide FlexStudent: £100 cash and £120 of Just Eat vouchers, paid as £10 a month for a year, for first-year students who pay in £500 and make five debit card payments by 11 December 2026. The page gives no closing date for the offer itself, and Nationwide says it may change or withdraw it at any time.
- NatWest and RBS: £100 cash and a four-year Tastecard, which NatWest values at £79.99 a year, paid within 10 days of opening according to the bank's July press release. NatWest says the offer can be withdrawn at any time because of limited availability.
- HSBC and TSB list no sign-up gift on their product pages, so for those two the overdraft and the savings rate are the whole pitch.
Read the exclusions before you move an account you already hold. Lloyds will not pay the £100 to anyone who has held a Lloyds, Bank of Scotland or Halifax student or graduate account since 1 August 2021, NatWest excludes anyone who has received a NatWest student incentive since July 2022, and Nationwide's offer is for first-year students who had no FlexStudent or FlexGraduate account open before 15 July 2026. A returning student with a student account at one of those banks should assume the cash is not on offer. Banks normally allow only one student account per person, and Nationwide says it will ask you to switch an existing one across, which the free Current Account Switch Service does in seven working days. The starting limits in the table apply to new accounts, so find out what limit the new bank will give you in your own year of study before you move anything. Lloyds adds a small trap of its own: it will not reissue a Deliveroo voucher if the email address on the application is wrong, and each voucher expires after 30 days.
Freebies against interest: the sums
Cash and vouchers top out at £220 at Lloyds and Nationwide, and that is the full figure only for students who meet every monthly condition. Set it against the cost of borrowing beyond the interest-free line. Lloyds quotes 39.9% EAR on graduate account borrowing above the interest-free amount, and at that rate £1,000 left outstanding for a full year costs about £399, which is simple arithmetic rather than a bank illustration. The railcard and the Tastecard are different animals, because they pay back only if you travel by train or eat out often enough to use them. Santander says the railcard could save a third on rail travel in Great Britain, while NatWest's £79.99 valuation of the Tastecard compares with the £39.99 sale price the Guardian spotted when it wrote up the accounts.
If you know you will never touch an overdraft, take the biggest freebie you qualify for. If you will, take the account with the largest limit you can reach in your own year of study and treat the gift as a bonus.
The regular savers attached to the accounts
Two of the banks add a regular saver. HSBC's pays 5.00% AER over a fixed 12-month term on deposits of £25 to £250 a month, and Santander's advertises 8.00% AER (variable) on up to £200 a month for the first 12 months, of which 5.00% is a bonus. Both sit above Bank Rate, which the Monetary Policy Committee held at 3.75% on 17 September by six votes to three, with the three dissenters preferring 4%; the next decision is due on 5 November. The catch with any regular saver is that each deposit earns interest only from the day it goes in, so £25 a month at 5.00% for a year earns roughly £8 on £300 paid in, again by simple arithmetic.
When the interest-free money stops
Every one of these overdrafts is repayable on demand, the interest-free part included.
After graduation the rules change bank by bank. HSBC converts a Student Bank Account to a Graduate Account on 31 July of the year you finish and reduces the interest-free amount each year. Lloyds steps down from £2,000 in the first year after graduating to £1,500 and then £1,000, charging 39.9% EAR on borrowing above each year's interest-free amount. TSB keeps an optional interest-free overdraft of up to £2,000 for three years after you graduate, a flatter and gentler cliff. NatWest says the interest-free amount reduces until the fourth year after graduation, when the account moves to a Select account and the interest-free overdraft ends. Santander transfers the account to its Edge Grad account automatically at the end of the course. The bigger limit is not automatically the better deal if you would otherwise leave university owing most of it.
Credit files matter here too, and the banks do not describe the effect identically. HSBC says it reports account activity, including overdraft use, to credit reference agencies, and that staying inside an arranged limit will not hurt a credit score, whereas Lloyds says an arranged overdraft adds to your overall borrowing and may affect the score. They agree on the danger zone: TSB warns that going over the limit or having payments rejected can lower a score, and HSBC says an unarranged overdraft lasting more than 30 days could damage a credit rating.
If you are opening one this week
Have the paperwork ready first. NatWest asks for your 16-digit UCAS code and HSBC for the 16-digit UCAS status code, while Santander accepts a student ID card or a letter from your university or college as proof of study. Santander's prize-draw window shuts on Friday 16 October and Lloyds's cash offer on Friday 30 October, and for Lloyds the £500 has to be in the account by that date, so a student whose loan has not landed yet should check the timing before applying.
