How it works

Income multiple

Mainstream UK lenders typically cap borrowing at 4.5× annual gross income (combined for joint applications). A few specialist lenders go to 5–5.5× for high earners or specific professions.

Outgoings deduction

Existing credit card balances, personal loans and car finance reduce borrowing capacity. Lenders subtract roughly 60× the monthly outgoing from the income-based maximum.

Stress test (+3%)

Since 2014 (FCA Mortgage Market Review) lenders must check you can afford repayments if rates rose ~3% above the product rate. The Bank of England removed the formal requirement in Aug 2022 but most lenders still apply it.

Loan-to-Value (LTV)

Your deposit as a % of the property price. 95% LTV is the typical max; better rates are available at 90%, 85%, 80%, 75% and 60% bands. A 25% deposit (75% LTV) usually gets meaningfully cheaper rates.

Term length

Standard UK term is 25 years but 30, 35, and even 40 are increasingly common. Longer terms lower the monthly payment but increase total interest paid significantly.

What this doesn't include

Credit score, income type (PAYE vs self-employed), bonus reliability, recent credit defaults, property type (BTL, new-build, leasehold) — all affect what lenders will actually offer. Always get a broker Decision in Principle.
