Quick answer
There is no single answer - it depends on the product. Unsecured personal loans typically go to £25,000-£50,000. Mortgages are calculated as 4 to 4.5 times gross income (sometimes more). Secured loans depend on available equity. Car finance depends on the vehicle value. Across all types, your actual maximum is restricted by your credit history, income, existing commitments, and each lender's specific criteria. What you are approved for is not necessarily what you should borrow.
Unsecured Personal Loans
Most mainstream unsecured lenders offer between £1,000 and £25,000. Some lenders extend to £50,000. The amount available depends on your income, credit score, and creditworthiness. Term lengths typically run from 1 to 7 years.
Mortgages
The primary benchmark is an income multiple:
- Most lenders: 4 to 4.5 times gross annual income
- Some lenders for higher earners: up to 5 or 5.5 times
- Lenders then run a full affordability model on top of the multiple calculation
Your deposit also determines how much you need to borrow. A larger deposit reduces the mortgage needed for the same property price.
Secured Loans and Second Charge Mortgages
The limiting factor is your available equity and the lender's maximum LTV:
- Maximum combined LTV (first mortgage plus second charge) is typically 80-85% of property value
- Some specialist lenders go to 90% LTV
- Minimum equity retained: usually 15-20% of property value
Amounts typically range from £10,000 to £500,000+ depending on property value and equity.
Car Finance
Linked to the vehicle price rather than primarily to income, though affordability is still assessed. HP and PCP deal amounts are set by the vehicle cost minus deposit. Personal loans for cars are assessed like any unsecured loan. Most car finance products are available up to around £100,000+ for appropriate vehicles with creditworthy applicants.
The Right Borrowing Amount
Understanding the maximum is one thing. Deciding the right amount for your circumstances is another. Run a genuine stress test: if your income fell by 20% for a sustained period, could you still meet all your financial commitments including the new borrowing? If the honest answer is no, you may be at the top of the range approved by a lender, but not necessarily at a level that is prudent for you.
Frequently Asked Questions
Yes, for most credit products. Lenders combine incomes on joint applications and therefore arrive at a higher maximum based on the income multiple or affordability model. Both applicants' credit profiles are assessed, however. If one applicant has significantly adverse credit, this may offset the income benefit of adding them. On a joint mortgage application, the weaker credit file can sometimes determine the rate available more than the combined income.
Not necessarily. The "how much can I borrow?" figures from calculators and Decision in Principle tools are indicative, not guaranteed. Full underwriting may reveal factors not captured in an initial assessment. A lender might offer less than the stated maximum if your committed expenditure is higher than their model assumes, if the property valuation comes in lower, or if further document review changes the picture. Always treat indicative figures as a starting point, not a commitment.
Deposit size directly determines your loan-to-value ratio, which in turn affects the rate you pay. A larger deposit reduces the mortgage you need to service and gives you access to better rates. Both of these can increase effective borrowing capacity - a lower rate at the same mortgage size means a lower monthly payment, which means your income can support a larger mortgage. Run the numbers both ways: deposit amount and monthly affordability together determine the maximum you can practically borrow.
Extending a mortgage term lowers the monthly payment for the same balance, which may allow you to pass an affordability assessment at a higher loan amount. However, lenders have caps on maximum terms and age at end of term (typically 70 to 75 for mortgages). For personal loans, terms are much shorter (1 to 7 years). Extending the term increases total interest paid over the life of the loan, even if the monthly payment falls.
No. The maximum a lender approves is a ceiling based on their risk model - not an endorsement of that amount as the right amount for you personally. You should make your own honest assessment of what you can comfortably repay across different income scenarios (including income dropping). Borrowing to the maximum approved is one of the most common financial mistakes UK households make.
