Getting Paid Without Burning Bridges: A Subcontractor's Cash Recovery Plan

Late payment is not a seasonal inconvenience. It is a persistent cash-flow risk that can decide whether a competent subcontractor survives a difficult project. The UK construction and trade sectors have spent years discussing the problem, yet small firms still find themselves chasing invoices months after the work is complete. The answer is not to become aggressive with every client. It is to build a recovery routine that is clear, documented and proportionate, so that slow payers understand you are organised and key relationships remain intact.

Start with the invoice, not the argument

A payment dispute is often easier to prevent than to win. Before work begins, confirm the client’s purchase order number, the correct legal entity, the invoicing address and any portal requirement. Make sure your invoice matches the contract: the right valuation period, the right description, the right amount and the right payment terms. Attach the evidence the client will need to approve it, such as signed sheets, photographs or completion certificates. If the client requires a particular format, use it. An invoice that is technically correct is harder to ignore and easier to escalate.

Put the payment terms in writing

If you have a written contract, check the payment period, the valuation date and the notice requirements. If you do not have one, confirm the terms in an email before starting work. A short message can be enough: “We will invoice monthly, payment due 30 days from invoice date, and all variations must be instructed in writing.” Keep it polite and factual. For construction contracts in the UK, the payment notice regime under the Housing Grants, Construction and Regeneration Act 1996 provides a framework for payment and adjudication, but it does not replace clear contractual terms. Scotland has its own arrangements, so confirm the position if your project crosses borders. The point is simple: do not rely on a conversation you cannot prove.

This week: a five-step cash check

First, list every invoice that is overdue and rank it by value and age. Second, check whether the client has issued a payment notice or a pay-less notice, and whether you have responded within any contractual time limit. Third, gather the evidence that supports the invoice: instructions, timesheets, delivery notes and correspondence. Fourth, send a short, firm reminder that refers to the invoice, the due date and the amount outstanding. Fifth, pick up the phone to the person who can actually approve payment. A call is not a substitute for a letter, but it often reveals whether the delay is administrative, disputed or deliberate.

Use escalation letters that preserve the relationship

A good escalation letter is not a threat. It is a record. It should state the invoice number, the work done, the amount due, the date payment was due and the date by which you expect payment. It should invite the client to identify any genuine dispute and set out what evidence is needed. Keep the tone professional and avoid personal criticism. If payment remains outstanding, send a second letter that refers to statutory interest and compensation under the Late Payment of Commercial Debts (Interest) Act 1998, where applicable. Mention that you reserve your rights, but leave the door open to a payment plan. The aim is to make non-payment more inconvenient than payment, without making the relationship impossible to repair.

Know when adjudication is the right tool

For construction contracts, adjudication can provide a relatively quick decision on a payment dispute. It is not free, and it is not always the best first move. Before adjudication, consider the value of the debt, the strength of your evidence and the cost of enforcement. A consultant can help you assess whether the contract gives you a right to adjudicate, whether the dispute is suitable and whether a negotiated settlement is more sensible. Adjudication is most effective when the paperwork is clear and the client understands that you are prepared to use it. It is least effective when it is used as a blunt instrument in a relationship you need to keep.

When to bring in a consultancy

Bring in external help when the debt is material to your cash flow, when the client has stopped responding, when the contract terms are unclear, or when a payment notice has been missed. A consultancy can review the file, draft the escalation correspondence, prepare a payment claim and advise on adjudication or mediation. It can also act as a buffer, which sometimes makes negotiations easier. The earlier you seek advice, the more options you have. Leaving a debt until it is six months old narrows the routes available and increases the pressure on your business.

Protect the relationship and the cash

The most effective collection strategy is consistent rather than confrontational. Invoice promptly, follow up on time, keep records and escalate in stages. Do not let a small administrative issue become a large legal one. Do not accept vague promises without a date. And do not assume that a long-standing client is immune from cash-flow pressure. A calm, documented approach gives you the best chance of recovering what you are owed while preserving the commercial relationship. If you need support, P.F.
