How to Switch Invoice Finance Provider Mid-Contract: A Complete Guide for UK SMEs

Switching invoice finance provider mid-contract is possible but requires careful planning. You need to check your notice period, understand how the old funder will handle outstanding ledger balances, coordinate a clean handover with the new provider, and manage debtor notifications if required. Done correctly, a switch can reduce costs and improve service without disrupting your cash flow.

Why UK SMEs Switch Invoice Finance Provider

Businesses switch invoice finance provider for several practical reasons. The most common are a better pricing offer from a competitor, dissatisfaction with service levels, a funder withdrawing from a sector, or the original facility no longer fitting the business as it has grown. Some SMEs also switch when a high street bank restructures its asset-based lending division and migrates clients to less favourable terms.

Whatever the trigger, the mechanics of switching are broadly the same. The key difference from switching a current account or energy supplier is that invoice finance involves a legal charge over your entire debtor book. That security interest means two funders cannot simply overlap without a formal legal agreement. Understanding this constraint early saves time and prevents expensive mistakes.

Before approaching any new provider, gather your current contract, the most recent facility letter, and your aged debtor report. These three documents will answer most of the questions a new funder will ask at first enquiry.

Reviewing Your Existing Contract: Notice Periods and Exit Clauses

The starting point for any switch is a thorough read of your current invoice finance agreement. Look specifically for four things: the minimum contract term, the notice period required to terminate, any minimum annual fee, and early termination penalty clauses.

Minimum terms of 12 or 24 months are common. If you are inside that period, the funder may charge a fee equivalent to several months of service charges to release you. Some agreements express this as a fixed sum; others calculate it as a percentage of the average monthly ledger over the preceding three to six months.

Notice periods in the UK market typically run from 30 days at the short end to 90 days for larger or more complex facilities. Some contracts with embedded bad debt protection carry a separate notice requirement for that element. If you serve notice but then fail to complete the switch, the facility will terminate regardless, leaving you without funding. Serve notice only when you have a credible replacement lined up.

If your agreement is unclear, ask your funder for a written confirmation of your outstanding obligations. They are required to provide this.

Understanding the Legal Charge and How It Is Released

When you sign an invoice finance facility, the funder takes a fixed charge over your book debts and typically a floating charge over the rest of your assets, registered at Companies House as a debenture. This charge prevents another lender from taking a competing interest in the same assets without consent.

To switch providers, the existing debenture must be released or subordinated before or at the same time as the new funder registers their own charge. In practice this happens in one of two ways.

The cleaner route is a full repayment and release. The new funder advances enough on day one to repay the old funder in full, the old funder releases its charge, and the new debenture is registered. This works when the new funder is comfortable funding the entire current ledger from the outset.

The alternative is a deed of priority, where the old and new funders agree which charge ranks first over which assets. This is used in more complex situations, such as where the old funder is unwilling to release immediately until a disputed debtor balance is resolved. Deeds of priority add legal cost and time, typically two to four weeks of solicitor involvement on each side.

Coordinating the Handover: Timeline and Parallel Running

A well-managed switch normally follows a six to ten week timeline from instructing a new provider to the first drawdown on the new facility.

Weeks one and two cover the new provider's credit assessment, KYC checks, and site visit if required. The new funder will want to see three to six months of management accounts, your aged debtor ledger, a sample of invoices and purchase orders, and your Companies House filings. They will also want to speak with your finance director or owner to understand the debtor concentration and any disputed invoices.

Weeks three and four cover legal documentation. The new facility letter, debenture, and any personal guarantee paperwork are drafted, negotiated, and signed. Your solicitor should review the debenture wording if the facility is above around £500,000.

Weeks five and six cover the practical handover. The new funder notifies the old funder formally, the old funder calculates the repayment figure, and funds flow to clear the old balance. In some cases a short parallel running period of five to ten working days is needed while both ledgers are reconciled. During this window you draw nothing from the old facility and begin uploading invoices to the new system.

Plan the switch to avoid month-end payroll dates or VAT payment deadlines.

Managing Debtor Notifications During a Switch

Whether your debtors need to be told about the switch depends on the type of facility you hold and the type you are moving to.

If you are switching from one disclosed facility to another, your debtors are already aware that their invoices are assigned to a finance company. They will need to be told to redirect payments to the new funder's trust account. A poorly managed notification can cause payments to arrive at the old funder's account after the facility has closed, creating delays and reconciliation problems.

The standard approach is to send a formal reassignment notice to each debtor on the day the new facility goes live. Many new funders will draft this letter for you and send it on your behalf. Check that the letter clearly states the new remittance address, the effective date, and a contact number for queries. Large debtors, particularly supermarkets or public sector bodies with long payment processing cycles, may need extra lead time to update their supplier payment systems.

If you are moving from a disclosed facility to a confidential invoice discounting arrangement, the notification process is different. Debtors are not told about the new facility, but you still need to manage the closure of the old disclosed account carefully so that final payments are not misdirected.

Calculating the True Cost of Switching

Before committing to a switch, produce a simple comparison of total cost over a 12-month period under the old and new facilities. Include all of the following items.

On the exit side: any early termination fee, the cost of legal work to release the old debenture, and any audit fee the old funder charges on closure. Some funders also retain a small reserve for 30 to 60 days after termination to cover late-arriving debtor payments or disputed invoices; factor in the cash flow impact of that retention.

On the new facility side: the arrangement fee, the service charge expressed as a percentage of turnover, the discount charge (typically priced over the Bank of England base rate, currently 3.75% as at 18 December 2025), any bad debt protection premium if applicable, and the annual review fee.

A saving of 0.1 percentage points on the service charge across a £2 million annual turnover is £2,000 per year. That saving needs to exceed the total switching cost before the move makes purely financial sense. Many SMEs find the switch is justified on service quality grounds even when the headline saving is modest.

Common Mistakes to Avoid When Switching

Serving notice too early is the most frequent error. If the new facility falls through during underwriting, you may be left with a terminated facility and no replacement. Serve notice only once the new facility letter is signed or at least conditionally approved subject only to legal formalities.

Failing to check debtor concentration limits is another common problem. A new funder may have stricter limits on how much of your ledger can be concentrated with a single debtor. If your largest customer represents 40% of your turnover and the new funder's limit is 25%, the available funding on day one will be lower than expected.

Underestimating the time required for KYC is also a recurring issue. If your business has complex ownership, overseas shareholders, or recent changes to directors, the new funder's compliance team will need additional documentation. Start gathering certified ID, proof of address, and corporate structure charts early.

Finally, do not overlook your existing funder's co-operation. The outgoing funder controls the timing of the debenture release. Maintaining a professional relationship throughout the process, and continuing to operate the old facility correctly until the final day, will reduce the risk of delays on their side.

Checklist

• ☐Obtain your current contract and identify the notice period, minimum term, and any early termination fee before approaching a new provider.
• ☐Request a written redemption figure from your existing funder so you know the exact amount needed to repay and release the facility.
• ☐Confirm the new funder's debtor concentration limits and compare them against your current ledger before signing a new facility letter.
• ☐Serve formal written notice to your existing funder only after the new facility letter is signed or conditionally approved.
• ☐Prepare debtor reassignment notices in advance and agree with the new funder who will send them and on which date.
• ☐Calculate the total switching cost, including exit fees, legal costs, and the new arrangement fee, and compare it against the projected 12-month saving.
