Top 10 Lenders to Secure a £1 Million Invoice Finance Loan in 2026

A £1 million invoice finance facility allows your business to borrow against the value of your unpaid customer invoices. Rather than waiting 30, 60, or 90 days for clients to pay, the lender advances you a percentage of each invoice value — typically 80% to 90% — within 24 to 48 hours of raising it. You retain control of your sales ledger and continue chasing payments as normal. Once your customer settles the invoice, the lender releases the remaining balance to you, minus their agreed fee. The facility can be structured as either disclosed (your customers know about the arrangement) or confidential (they do not), depending on your preference and the provider's terms.

To qualify for a £1 million invoice finance facility, your business will typically need an annual turnover of at least £1.2 million to £1.5 million, as the facility limit is based on your sales ledger value. Lenders will review the quality of your debtor book, the creditworthiness of your customers, and your trading history — most providers want to see at least 12 to 24 months of trading. You must be a UK-registered limited company or LLP, and your invoices should be raised on standard payment terms (usually 30 to 90 days) to creditworthy commercial or public sector customers. Businesses with concentration risk — where a single customer represents a large share of your ledger — may face a lower advance rate or additional scrutiny.

Invoice finance costs are typically made up of two elements: a service fee, which covers the administration of the facility and is usually a percentage of your turnover (commonly between 0.5% and 3%), and a discount charge, which is the interest applied to the funds you draw down, calculated daily and linked to the Bank of England base rate plus a margin. For a £1 million facility, rates tend to be more competitive than for smaller arrangements due to economies of scale, though the exact pricing will depend on your debtor quality, sector, and trading history. Terms are usually agreed on a rolling 12-month contract with a notice period, and facilities can be structured as whole turnover (all invoices financed) or selective (you choose which invoices to finance).

Invoice finance differs from a revolving credit facility in that its funding limit grows in line with your sales ledger — as your invoicing increases, so does your available capital — whereas a revolving credit facility has a fixed cap agreed upfront. Compared to an unsecured business loan, invoice finance does not typically require a personal guarantee or a fixed charge over business assets, since the invoices themselves serve as security. Invoice finance also offers faster access to working capital than most unsecured loans, which require full underwriting of your business rather than primarily assessing your debtor book. However, unsecured loans provide a lump sum with fixed repayments, which can suit businesses wanting certainty over monthly costs, whereas invoice finance costs fluctuate with your borrowing and turnover levels.

When evaluating providers for a £1 million facility, look for a lender with experience in your sector and a track record of handling facilities of this size. Check their advance rates — the percentage of invoice value they will release upfront — and whether they offer confidential or disclosed arrangements to suit your customer relationships. Review the service fee structure carefully: some providers charge a flat percentage of turnover, while others have tiered rates that reduce as volumes increase. Ask about their collections process if you are considering a factoring arrangement, and clarify whether there are any hidden costs such as arrangement fees, exit fees, or minimum volume commitments. Finally, assess the quality of their client support — at this facility level, you should expect a dedicated relationship manager rather than a call centre.

The timeline for securing a £1 million invoice finance facility typically ranges from two to six weeks, depending on the complexity of your debtor book and how quickly you can provide the required documentation. The process usually involves an initial consultation, submission of your sales ledger and management accounts, a credit review of your major customers, and a formal proposal from the lender. Once you accept the proposal, legal documentation is drawn up and the facility can go live. Some specialist providers offer accelerated onboarding for straightforward cases, potentially activating the facility within 10 to 14 working days. Having your paperwork — including aged debtor reports, management accounts, and company financials — prepared in advance can significantly speed things up.
