What affects UK business loan approval speed?

Product type is the biggest single driver

Small revenue-linked products - merchant cash advances under £50k, some revenue-based facilities for digital businesses - can produce an indicative decision in hours and drawdown in two to three working days. The underwriting model is built around card data or platform data, the documentation requirement is light, and the lender's risk window is short.

Vanilla unsecured term loans up to around £150k typically decision in one to three working days for clean applications, with drawdown in three to seven days. Larger unsecured loans and any deal involving more than the standard pack can stretch to two weeks.

Secured products - commercial mortgages, bridging finance, larger asset finance, larger invoice finance - involve valuations, legals and sometimes searches. One to three weeks is normal for a straightforward deal, longer for complex or large transactions.

Document readiness changes the timeline more than people expect

An application submitted with a complete, clean pack runs through underwriting faster than one that needs three or four follow-ups for missing items. Each follow-up usually adds at least a day, sometimes more if the missing item requires accountant or solicitor input.

Owners who pre-build a standard document pack - and refresh it monthly - can move from quote to drawdown noticeably faster than owners who scramble after applying. The difference can be one to two weeks on a deal of any size.

Affordability complexity adds time

Simple, clean affordability cases - one trading entity, predictable monthly revenue, no existing debt, clean bank statements - underwrite quickly. The model accepts them, a credit analyst signs off, and the deal moves.

Complex cases take longer. Group structures, intra-company flows, seasonal revenue, recent significant one-offs, multiple existing facilities, recent adverse credit with an explanation - each of these adds underwriting touches. The lender may ask for management accounts, an accountant's letter, or a call with the director. Each touch is at least a day.

External dependencies that slow things down

On secured deals, valuations are usually the longest single item. A commercial property valuation can take one to three weeks depending on the surveyor's diary and the complexity of the property. Bridging deals sometimes use a desktop or AVM valuation to shave days off but the lender still has to be comfortable.

Legals - both the lender's solicitor and yours - can add a week or two on any secured deal. Title issues, planning concerns, missing certificates or unexplained charges in the title register can each add days. Engaging a solicitor familiar with commercial finance, rather than a general practitioner, materially helps.

External checks - sanctions lists, anti-money-laundering verification, source-of-funds evidence - are usually quick but can occasionally flag and require follow-up. Politely-exposed-person checks, complex group ownership and overseas directors all add steps.
