Using Escrow and Retention Payments Properly

Selling your business is a high-stakes process, and getting paid in full is never a guarantee. Escrow and retention payments are powerful tools to protect both buyer and seller—but only if you set them up correctly. This guide cuts through the jargon, explains exactly how these mechanisms work in the UK, and gives you a practical, step-by-step approach to using them properly when selling your business.

When selling a UK business, the fear of either party not honouring their side of the deal is real. Escrow and retention arrangements are designed to bridge the trust gap and reduce risk for both seller and buyer. But they're not the same thing, and using them incorrectly can create more problems than they solve.

An escrow payment involves a neutral third party (the escrow agent) holding funds until certain agreed conditions are met. This might be the completion of legal paperwork, delivery of assets, or satisfaction of specific warranties. The escrow agent—usually a solicitor, specialist provider, or sometimes even a bank—releases the money when everyone is satisfied the deal terms are met.

A retention payment is when a portion of the purchase price is held back by the buyer (or in escrow) for a set period after completion. This money is then paid out later, usually if there are no claims under warranties, indemnities, or other post-sale conditions. Both mechanisms are common in UK business sales, especially where there are concerns about liabilities or performance.

It's essential to understand why these mechanisms exist: neither party wants to be left exposed. The seller wants certainty of payment. The buyer wants protection in case the business isn't as described, or if unexpected liabilities emerge after completion. Used properly, escrow and retention arrangements can create much-needed trust and smooth the path to completion.

Escrow and retention payments aren't required by law, but they are standard practice in many UK business sales—especially where the transaction is complex, the sums are significant, or there are uncertainties about the business's condition. Most often, they're used when there are warranties, indemnities, or completion deliverables that can't be ticked off instantly at completion.

You might use escrow if: the buyer wants assurance that their money won't be released until they've received all assets and documents; the seller wants proof that the funds are available; or there's a dispute over a specific item that needs to be resolved after completion. An escrow arrangement can prevent last-minute walkaways, and can also be used for staged payments.

Retention payments are especially common where there are potential liabilities (for example, an outstanding tax enquiry, unresolved employee claims, or concerns over customer contract renewals). The buyer holds back part of the price, and pays it out if no claims arise within a set period—typically 6-24 months.

The key advantage for the seller is increased buyer confidence (which can help secure a better price or a faster sale). For the buyer, it’s a safety net against unexpected costs or misrepresentations. But both sides need to be clear about exactly what triggers the release or forfeiture of the held funds—and these terms must be set out unambiguously in the Sale and Purchase Agreement (SPA).

• Warranties or indemnities in the SPA that might lead to future claims
• Unresolved disputes or due diligence issues (e.g. tax, legal, IP)
• Uncertainty over business performance or customer retention post-sale
• Complex asset transfers or staged handover of business elements

You should always seek legal advice before agreeing to escrow or retention arrangements. The wrong setup can tie up your money for years, or fail to give you the protection you need.

In UK business sales, an escrow arrangement is usually set up through a solicitor or specialist regulated provider. It's vital that the escrow agent is truly independent, FCA or SRA registered, and experienced in business transactions—not just residential property.

Both parties sign an escrow agreement that spells out exactly when and how the funds will be released. The agent then holds the buyer’s money in a ring-fenced client account. The seller only receives the money when all the agreed conditions are satisfied—often upon Companies House filings, asset transfers, or confirmation of no outstanding liabilities.

The terms should cover: what triggers a release (e.g. completion, delivery of specific documents, clearance of debts), the process for raising a dispute, and what happens if there’s a disagreement. It’s also vital to specify the agent’s fees (which can range from a flat fee of £500 to 0.1–0.5% of the escrowed amount), who pays them, and what happens if the agent ceases to trade.

Escrow is especially useful for staged payments, such as when a portion of the price is released at completion, and further amounts are released once specific handover milestones have been met. This can be important if, for example, the seller is staying on for a transition period.

• Choose an FCA-regulated or SRA-registered escrow provider
• Define clear release triggers and dispute resolution steps in the agreement
• Ensure both parties authorise releases (dual signatures or written confirmation)
• Budget for escrow fees and agree who pays them upfront
• Check what happens if the agent is unable to act or becomes insolvent

A retention payment is when part of the purchase price is withheld—often by the buyer, but sometimes held in escrow as a compromise. The idea is that if any post-completion warranty or indemnity claim arises, the buyer can deduct the cost directly from the retention sum, rather than chasing the seller later.

The main risk for sellers is that the retention period drags on, or that buyers make spurious claims to avoid releasing the funds. For buyers, the risk is that the retention sum isn’t enough to cover real liabilities, or that the seller becomes uncontactable (or insolvent) if a claim does arise. For both sides, airtight documentation is crucial.

In the UK, retention periods usually run from 6 to 24 months, depending on the nature of the business and the risks uncovered during due diligence. The triggers for release should be crystal clear: a set date if no claims are notified, or immediately upon resolution of any disputes. Retentions can also be split into tranches, with staged releases after, for example, 6 months and 12 months.

A common mistake is failing to specify what counts as a valid claim, or allowing the buyer to make vague or unsubstantiated claims to block release. Sellers should insist on a clear process for notifying claims, a time limit for investigation, and a requirement for evidence.

• Define exactly what claims can be made against the retention (e.g. tax, HR, IP)
• Require written notice and supporting evidence for any claim
• Set time limits for both claim notification and resolution
• Agree up front what happens if the retention is not released on time

For extra security, especially in larger deals, you can agree to hold the retention sum in escrow rather than with the buyer. This reduces the risk of funds being withheld unfairly or the buyer becoming insolvent.

Getting escrow and retention arrangements right takes careful planning and negotiation. Below is a practical, step-by-step process that UK small business owners can follow to ensure payments are protected and disputes are minimised.

Remember: your solicitor should be closely involved in every step. Never be tempted by shortcuts, handshake agreements, or free online templates—these mechanisms only work if the legal documentation is watertight and reflects the real commercial risks of your deal.

In the UK, escrow and retention arrangements are governed by contract law and, where relevant, the rules of the FCA or SRA. It’s vital that the agreement is drafted by someone who understands both the legal and commercial realities of business sales, as well as current regulations.

For sellers, one of the biggest issues is tax timing. HMRC typically treats the whole consideration, including any sum held in escrow or retention, as received at completion, unless the sum is genuinely contingent (i.e. you might never receive it). This means you may owe Capital Gains Tax (CGT) on the full sale price, even if part of it is held back. There are exceptions and nuances—discuss with your accountant before completion.

Escrow agents must comply with anti-money laundering (AML) and Know Your Customer (KYC) rules. This means both seller and buyer will need to provide proof of identity and source of funds. Delays are common if documentation isn’t in order, so start early.

Another legal consideration: if there is a dispute over release, the escrow agent may require a court order before releasing funds. This can be expensive and time-consuming—so a robust dispute resolution clause (such as requiring mediation or expert determination) is essential.

• Check the FCA or SRA status of any escrow agent before transferring funds
• Discuss tax treatment of escrow/retention with your accountant before completion
• Ensure AML/KYC checks are completed in advance to avoid delays
• Include a clear dispute resolution process in the agreement

Even experienced business owners can fall into traps when it comes to escrow and retention payments. These mistakes can cost you time, money, and even the sale itself. The most common issues usually stem from unclear documentation, using the wrong provider, or failing to plan for edge cases.

One of the biggest mistakes is agreeing to an open-ended retention or escrow period with vague triggers for release. This gives the party holding the money too much power, and can lead to protracted disputes. Always insist on a firm end date and objective criteria for release.

Another frequent error is failing to address what happens if the buyer or seller becomes insolvent during the retention period, or if the escrow agent ceases trading. Without clear provisions, you could be left chasing money through the courts or insolvency proceedings.

It's also a mistake to use an escrow provider with no track record in business sales. Property-focused agents or unregulated online services often lack the expertise to handle the complexities of a business transaction, and may not offer adequate client money protection.

• Never use an unregulated or overseas escrow provider
• Avoid vague or subjective release conditions in your agreements
• Don’t ignore the tax consequences—check with your accountant early
• Don’t rely on handshake or informal deals for retentions

Lastly, don’t underestimate the time it takes to negotiate and set up these arrangements. Delays with escrow/KYC checks, disputes over wording, or last-minute changes can all push out your completion date. Build in extra time and keep all parties informed throughout.

To see how escrow and retention payments work in real life, it’s helpful to look at some practical UK examples. These scenarios highlight best practice and common pitfalls, so you can avoid costly mistakes.

Case Study 1: Tech SME Sale with Escrow for IP Transfer. A London-based software business was sold for £2 million. £1.8 million was paid at completion, with £200,000 held in escrow by a regulated law firm until all source code and IP transfer documents were delivered and registered. The escrow released the funds promptly after Companies House confirmation, giving both sides confidence to proceed.

Case Study 2: Engineering Firm with Retention for Warranty Claims. An SME engineering firm in the Midlands was sold for £1.5 million. The buyer held back £150,000 (10%) in retention, to be released after 12 months if no warranty claims arose. A customer dispute emerged 8 months in; the claim was investigated and settled for £40,000, with the balance released at the end of the period. The SPA specified the claims process and time limits clearly.

Case Study 3: Retail Business Pitfall—Unregulated Escrow Provider. A small chain of shops sold for £400,000 used an unregulated online escrow service, which went bust before funds were released. The seller lost £50,000 that should have been protected. Had they used an FCA-regulated provider, the funds would have been ring-fenced and protected under client money rules.
