How Much Can I Borrow on a £100,000 Salary?
On a £100,000 salary, UK lenders typically offer between £500,000 and £600,000. That £100,000 gap exists because premium lenders compete aggressively for high earners. Several building societies offer up to 6x income, and private banks offer bespoke terms that can push even higher with the right deposit and profile.

What If You Have Overtime or Bonuses?
At £100k, many earners have significant variable income. A £30,000 annual bonus with a lender accepting 60% adds £18,000 to assessed income, increasing your maximum mortgage by £72,000 to £117,000. Private banks and premium divisions often take a more holistic view of income, considering assets, investment portfolios, and career trajectory alongside base salary. If your total compensation is significantly above £100k, it is worth speaking to private banking divisions directly or having a broker approach them on your behalf.
What Could You Buy?
A larger deposit can unlock higher income multiples at some lenders. At 25% deposit, several lenders in the table above would offer even more. Use our calculator to check your exact figure with your specific deposit.
At this level, premium London properties become accessible — period houses in desirable boroughs, large flats in zones 1-2, and substantial family homes in commuter towns. Outside London, you can comfortably afford top-end properties in most areas. Be aware that properties over £625,000 attract higher stamp duty for first-time buyers, and the standard rate applies above £500,000 for additional properties.
What Reduces Your Borrowing?
Even at £100k, lenders still subtract commitments before lending:
- Credit cards — a combined £30,000 limit counts as roughly £900/month. High earners often have high limits they do not use — closing unused cards before applying is particularly impactful.
- Car finance — a £600/month lease could reduce your mortgage by £30,000 to £45,000. Consider whether settling the finance before applying would be cost-effective.
- Student loans — Plan 2 repayments on £100k are around £643/month, a significant deduction. Plan 1 repayments are lower. Some lenders are notably more lenient in how they factor student loans into their calculations.
Buying with a Partner
A joint income of £200,000 could unlock borrowing of £800,000 to £1,300,000. At this level, private banking divisions actively compete for your business. Bespoke underwriting means the income multiples are negotiable, and some private banks will consider assets and investment portfolios alongside salary. A whole-of-market broker with private bank access can often secure terms that are not available directly.
