What Happens If You Don't Pay Your Student Loan UK — Complete Guide

What happens if you don't repay your student loan, can't afford it, or ignore SLC. How repayments work, avoiding arrears, self-employed rules, living abroad, and when loans get written off.

Salary and income data is based on ONS and other official UK statistical sources. Figures are averages and may not reflect your individual circumstances.

Student loans work differently to normal debt — you only repay when earning over the threshold, and the loan is eventually written off. Here’s how it all works and what happens in different scenarios.

How Student Loan Repayment Actually Works

Automatic Repayment (If Employed)

DetailHow It Works
PAYE deductionTaken automatically from salary
You can’t opt outMandatory once over threshold
Employer deductsLike tax and National Insurance
Shown on payslipAs “Student Loan” deduction
No choice in amountFixed percentage of earnings over threshold

Key point: If you’re employed and earning over the threshold, you can’t “not pay” — it’s taken before you receive your salary.

Does Student Loan Affect Credit Score?

Credit Score Impact

FactorImpact
Appears on credit report?No
Affects credit score?No
Affects mortgage applications?Yes (indirectly)
Affects other borrowing?Sometimes

How It Affects Mortgages

FactorHow It Matters
Reduces net incomeLenders see lower take-home pay
Affordability calculationRepayments included in outgoings
Borrowing power reducedBy roughly 10-15% for typical borrower
Not shown as debtBut affects what you can borrow

Example: £50,000 salary borrower with Plan 2 loan might borrow £15,000-£20,000 less than someone without a student loan.

Overpaying Your Student Loan

Should You Overpay?

FactorConsider
Interest rateCurrently RPI + up to 3% (can be high)
Likely to repay in full?Most won’t — overpaying may be wasted
Other debts?Pay high-interest debt first
Other savings goals?ISA, pension, house deposit may be better
Income trajectoryIf earning £60k+ long-term, may repay anyway

When Overpaying Makes Sense

SituationRecommendation
High earner (£60k+)Will likely repay — overpaying reduces interest
Small balance remainingNear end of loan — clear it
Near write-off dateDon’t overpay — let it write off
Lower/average earnerDon’t overpay — unlikely to repay in full anyway

Refunds If You Overpay

SituationWhat Happens
Overpaid after balance clearedSLC refunds automatically
Overpaid near write-offCannot reclaim — be careful
PAYE continued after clearingContact SLC for refund
Time limitMust claim within set period

Myth vs Reality

MythReality

“Bailiffs can chase student loans”No — SLC uses different recovery methods
“It affects my credit score”No — doesn’t appear on credit reports
“I’ll lose my house”No — can’t secure against property
“It’s written off at 65”Only some Plan 1 loans — others based on years
“Interest is capped”Interest can be RPI + 3% (currently very high)
“Overpaying always makes sense”Most people won’t repay in full — overpaying wastes money
