Realistic timelines by product

"Fast" claims are only meaningful per product, because the underwriting work differs. These are the realistic bands we see across the panel, assuming documents are ready; individual cases vary.

### Realistic UK decision and funding timelines by finance product, assuming documents ready. Indicative, compiled from FundBiz product pages and published lender claims, July 2026.

| Product | Decision | Money lands | Why |
| --- | --- | --- | --- |
| Revolving credit facility (already open) | Already approved | Same day drawdown | Underwriting was done when the limit was agreed |
| Merchant cash advance | Same day to 48 hours | Same day to 5 days after decision | Underwritten on card-takings data |
| Fintech term loan (open banking) | Hours; Funding Circle advertises as little as 1 hour | 1 to 3 working days | Automated underwriting on live bank data |
| Specialist short term loan | Same day to 48 hours | 1 to 5 working days | Statement-based underwriting, light security |
| Invoice finance (first facility) | Days | First advance ~1 to 2 weeks | Debtor book verification takes time; fast per-invoice after setup |
| Asset finance | 1 to 5 days | Days to weeks | Asset valuation and supplier coordination |
| Commercial mortgage / bridging | Days to weeks | Weeks | Valuation and legal work cannot be compressed |

Note the first row: the fastest money is the facility you opened before you needed it. If urgency is a recurring pattern in your business, agreeing a revolving credit facility in a calm week beats every emergency application in a bad one.

What genuinely speeds an application up

Lender pipelines are largely fixed; the variable is how much of the checklist you clear in the first submission. Docs-ready means:

• Bank statements, ideally via open banking. The last 3 to 6 months of business bank statements, or an open banking connection, which replaces days of paper-chasing with a data feed.
• Filed accounts current. Latest filed accounts plus recent management accounts if the filed set is dated. Overdue Companies House filings are checked as a matter of routine and stall everything.
• Director ID ready. Photo ID and proof of address for every director who will sign or guarantee, available on day one, since identity verification is a hard gate before payout.
• A specific amount and purpose. "£40,000 for stock for a confirmed order" underwrites in hours; "as much as possible for general purposes" invites questions.
• Know your card and invoice numbers. MCA lenders want monthly card volumes; invoice finance wants the aged debtor list. Having them ready removes a full round-trip.

The speed premium: urgent money costs more

Fast lending and cheap lending are different products. Speed comes from lighter underwriting, and lenders price that risk: specialist fast money typically costs materially more per pound than a slower bank facility. That is a fair trade for a short, urgent, profitable need, such as stock for a confirmed order, and a poor trade for long-term funding. Two disciplines protect you: convert every quote to total pounds repaid, using the factor rate to APR converter for factor and monthly rates, and ask whether a cheaper product could still land inside your real deadline. Deadlines are often softer than they feel; a week of patience can be worth thousands. For the duration question rather than the speed question, see short term business loans, which covers 3 to 18 month lending and its true cost.

"Instant approval": the claims to distrust

• "Guaranteed approval" or "no credit check". No genuine lender guarantees approval before underwriting. This framing is the classic mark of upfront-fee harvesting.
• Upfront fees to "release" or "secure" funds. Real lenders deduct arrangement fees from the advance or add them to the balance. Paying a fee before any money moves is the scam shape itself.
• "Instant decision" meaning instant filter. Legitimate lenders do offer automated indicative decisions in minutes; the real approval follows document checks. The claim is not false, but read it as "instant maybe".
• Pressure to sign today. A quote that expires in hours is a negotiation tactic, not a market condition. Reputable offers survive a day of scrutiny.

Declined today? Still fundable this week

The most common fast-funding scenario we see is not a business that woke up needing money; it is a business that applied weeks ago, waited on its bank and got a no. The clock did not stop with the decline. Specialist lenders underwrite on the last few months of bank statements and current trading, exactly the evidence a declined-but-trading business already holds, so with documents ready the realistic path is a specialist decision within 48 hours of the decline and funds the same week. Start with what to do after a business loan decline, or find your specific scenario, from CCJs to HMRC arrears, in the decline scenarios hub.

Eligibility

FundBiz arranges fast business funding for UK limited companies, LLPs and partnerships of 4 or more partners only. Sole traders are outside our scope. Checking eligibility uses a soft search with no credit-file footprint, and the checker routes your file to the lenders whose criteria it actually fits, which is itself the biggest speed lever: the fastest application is the one that does not get declined first.

Related finance

For the duration question, see short term business loans (3 to 18 months). If the urgency comes from a timing gap in cash, a quiet season, a slow payer, stock bought ahead of demand, cash flow loans covers how to size and shape that borrowing. For repeat urgency, a revolving credit facility makes the next draw same-day. Card-led businesses can compare a merchant cash advance, and business loan interest rates shows what the speed premium looks like against the wider market.
