Underwriting process

How lenders make underwriting decisions

Underwriting can feel like a black box, but the questions lenders are actually asking are broadly consistent across products: can this be repaid, and what happens if it can't. Knowing what sits behind those two questions makes the process far less opaque.

Category: How it works

Product: Commercial Loans

Core assessment: Affordability, security, exit
Typical decision speed: 24 hours to several weeks by product
Common referral triggers: Adverse credit, complex structure, valuation issues
Who decides: Automated score, human underwriter, or credit committee

Affordability and covenant strength

For business lending, underwriters assess whether cash generation comfortably covers repayments, usually applying a stress margin above current rates. For investment property, this becomes rental cover — the ratio of rental income to mortgage cost — and for bridging, the strength of the exit route.

Security and loan-to-value

The property or asset offered as security is assessed for value, marketability and condition. Specialist or unusual assets — leisure properties, HMOs, land without planning — reduce the pool of lenders willing to proceed and often result in lower LTVs to compensate for reduced marketability.

Valuation and condition of the security
Ease of resale if repossession were ever needed
Existing charges or debt secured against the same asset

Credit history and background checks

Personal and business credit history, director conduct history, and AML/source-of-funds checks all feed into the decision. Historic issues are rarely an automatic decline; how they're explained and how long ago they occurred matters more than the fact they exist.

Decision routes: automated versus manual

Smaller, simpler facilities are often approved through automated scoring within minutes or hours. Larger or more complex deals go to a human underwriter and, above certain thresholds, a credit committee — which is why timescales vary so widely between a £20k asset finance deal and a £5m commercial mortgage.

Frequently asked

What's the single biggest factor in an underwriting decision?

For most products it's demonstrable ability to repay — through business cash flow, rental income or a credible sale/refinance exit — with security as the backstop rather than the primary factor.

Can a strong broker actually change the outcome?

Yes, in the sense that a well-presented case with the right supporting evidence and the right lender match is far more likely to be approved than the same facts presented poorly to the wrong lender.

How long does underwriting typically take?

From same-day for automated asset finance decisions to several weeks for larger, committee-approved commercial mortgages, depending on complexity.

What happens if I'm declined by one lender?

It's common, and doesn't mean the deal is unfundable — different lenders weight risk factors differently, which is exactly why a whole-of-market approach matters.

Will underwriters ask for more information after the initial application?

Almost always, at least once. Clarifying questions on income, security or credit history are a normal part of the process, not necessarily a sign of a problem.
