Fast business loans in the UK, from same day to 48 hours
The only routes that reliably put money in your account within 24 to 48 hours are a loan or overdraft from the bank you already use, an online lender that decides from open banking, and a card-sales advance from your payment provider. Speed costs extra; on a £5,000 need the gap between the quickest and the cheapest option is several hundred pounds.

What lenders publish about speed
Adverts blur a fast decision with fast money. This table sticks to what each lender states on its own site.
| Route | Published speed | Size | Catch |
|---|---|---|---|
| Your own bank (NatWest example) | Same day if you apply online, are unconditionally accepted and sign by 16:30, Monday to Friday | £1,000 to £100,000 | Existing customers get the fast lane; a personal, director or member's guarantee may be required. |
| Overdraft increase | Online for limits up to £50,000 (NatWest) | Usually small | Arrangement fee, reviewed after 12 months. |
| Online lender (Funding Circle) | Decision in as little as 5 minutes; funds typically within 48 hours of accepting an offer | £10,000 to £750,000 | Limited companies; rates from 6.9% a year. |
| Card-sales advance (Square) | Money “in days, not weeks” | Sized to your card takings | Not regulated by the FCA; fixed fee. |
| Start Up Loan | Within a month if your plan and cash flow forecast are ready | £500 to £25,000 | Cheap at 7.5%, but not fast. |
Most merchant cash advance providers do not publish a decision time or a rate card, so we do not quote one. Ask any provider for both in writing before you hand over bank statements. One enquiry reaches our partner's panel of more than 200 UK lenders, so you are not stuck with the first answer.
What paying for speed costs, worked through
The house example: a shop taking £5,000 a month on cards needs £5,000 this week to buy stock. Three ways to fund it:
- Card-sales advance. An illustrative quote (example numbers, not a real offer): £5,000 repaid as £6,000 at 15% of card takings. £5,000 × 15% = £750 a month, so it clears in £6,000 ÷ £750 = 8 months. Cost: £1,000.
- Overdraft. At NatWest's representative 13.37% EAR on a £5,000 limit, fully drawn for the same 8 months: £5,000 × (1.13378/12 − 1) = £436.28, plus the £100 arrangement fee. Cost: £536.28, less if you pay it down as takings come in.
- 12 month loan. At 15%, the middle of our partner's panel range: £451.29 a month, £415.50 interest. Cheapest of the three, but a fixed payment every month whatever trade does.
The verdict: if the stock sells within weeks and you already have an overdraft, use it. If you have no facility and the money has to arrive this week, the card-sales advance is the only option of the three that does not depend on your bank, and its fee is the price of that. If you can wait a week, a term loan is cheaper.
How to get the money faster
- Apply on a Monday to Thursday morning; Friday afternoon applications often roll to Monday.
- Connect open banking instead of uploading statements. It removes a manual review step.
- Have photo ID, proof of address and three to six months of bank statements to hand.
- Answer underwriter questions the same day. A dip in takings or a large transfer will be queried.
- Check the offer's total repayable in pounds, not just the rate, before you e-sign.
When paying for speed makes sense
Fast funding earns its premium when the spend has a short, clear payback: an emergency repair that reopens the till, stock for a proven busy week, or payroll while a large invoice clears. It does not make sense for a loss-making quarter or a long refurbishment, and it never makes sense for repaying another advance. Read when not to take a merchant cash advance and the factor rates guide before signing one. If card fees are eating the margin you are trying to protect, start with a free statement review.

Questions people ask
Can I get a business loan the same day?
Yes, from your own bank if it already holds your account. NatWest, for example, pays funds the same day if you apply online, are unconditionally accepted and sign by 16:30, Monday to Friday. Elsewhere, a decision can be same day but the money usually lands within one to two working days: Funding Circle pays out typically within 48 hours of accepting an offer.
What is an instant decision business loan?
A loan where the lender scores your application automatically, often from open banking data, and returns an offer in minutes. Funding Circle advertises a decision in as little as 5 minutes. An instant decision is not instant money: e-signing, ID checks and the payment run still take time.
Is there fast business funding with no credit check?
Card-sales advances come closest. Square bases offers on your Square sales data, not your credit history, so your credit file is not the deciding factor. Loans always involve a credit check; anyone advertising a 24 hour loan with no checks at all should be checked on the FCA register before you share bank statements.
Does fast funding cost more?
Usually, yes. On our £5,000 worked example, an illustrative card-sales advance costs £1,000, an overdraft at NatWest's representative rate about £536 including the arrangement fee, and a 12 month loan at 15% £415. Speed is worth paying for when not having the money costs more.
How do I get the money faster?
Apply early in the week, connect open banking rather than uploading PDFs, have photo ID and three to six months of bank statements ready, and answer underwriter questions the same day. Applications that land on a Friday afternoon often wait until Monday.
