You have delivered the work, sent the invoice, followed up more times than you can count — and still nothing. Unpaid invoices are not just a cash flow problem; they are a drain on your time, your energy, and your patience.

At some point, it makes sense to stop chasing and start acting. Bringing in a professional to handle the recovery process can be one of the most practical decisions a business owner makes. But knowing how to choose the right firm, what to expect from the process, and where the pitfalls lie — that is where most people get stuck.
This guide covers everything you need to know, step by step.
What These Professionals Actually Do
When a debt has gone unpaid for too long, enforcement specialists step in to recover what is owed on your behalf. They handle everything from sending formal demand letters and negotiating directly with the debtor, to escalating matters through the courts if needed.
A good debt recovery agency does not just chase money — it manages the entire process strategically, using legal tools that most creditors simply do not have direct access to. That includes County Court Judgments (CCJs), High Court Enforcement, attachment of earnings orders, and charging orders on property.
Some firms also offer ongoing credit control support, helping you put better payment processes in place so you are less likely to be in this situation again in future.
When Should You Actually Bring Someone In?
Many businesses wait far too long. The general rule of thumb is this: if an invoice is more than 60 days overdue and the debtor is not engaging constructively, it is time to get professional help.
The older a debt becomes, the harder it is to recover. Debtors move, change bank accounts, or — in the worst cases — enter insolvency. Acting early gives you the best chance of a successful outcome and often signals to the debtor that you are serious, which can be enough to prompt payment on its own.
How to Choose the Right Firm
Check Their Credentials
For consumer debts — money owed to you by individuals — the firm must be authorised and regulated by the Financial Conduct Authority (FCA). For commercial debts, look for membership of the Credit Services Association (CSA), which sets professional standards for the industry. Do not skip this step.
Understand How They Charge
Fee structures vary widely. Some firms charge a fixed upfront fee; others work on a no-win, no-fee basis, taking a percentage of whatever is recovered — typically between 10% and 25%. A contingency model can feel low risk, but always check whether additional charges apply if the case goes to court.
Ask About Their Methods
The firm you hire will be contacting your debtor in your name. Ask them directly: how do they communicate with debtors? What does their escalation process look like? Are they able to handle legal proceedings in-house, or will you need to instruct a solicitor separately? These questions will quickly tell you whether they are the right fit.
Look at Their Track Record
A reputable firm will be happy to share case studies, client references, or success rate data. If they are vague or evasive when you ask, treat that as a warning sign.
What to Prepare Before You Make Contact
Before you approach any firm, gather the following:
• A copy of the original invoice and any related contracts or agreements
• A record of all previous payment requests and any responses received
• The debtor's full name, trading name (if applicable), and last known address
• Any dispute history — if the debtor has raised a complaint or query, document it
The stronger your documentation, the more leverage you have — both in negotiation and in any legal proceedings that may follow.
A Note on Personal Debt Recovery
If you are an individual — rather than a business — trying to recover money from another person, the process works slightly differently. A personal debt recovery agency will typically focus on locating the debtor, making formal demand, and assisting with court proceedings if needed. The legal routes available to you are the same, but the agency's approach will be tailored to the consumer context and must comply with stricter FCA regulations.
What to Watch Out For
• Firms that guarantee full recovery — no reputable agency can promise this
• Vague or unclear fee schedules with hidden escalation charges
• No FCA registration when dealing with consumer debts
• Agencies that rely solely on threatening letters with no genuine legal follow-through
• Poor communication — if they are slow to respond to you, they will likely be slow with your debtor too
Frequently Asked Questions
How long does the debt recovery process take?
It depends on how the debtor responds. Cases resolved through negotiation can be wrapped up in a few weeks. If legal proceedings are required — such as applying for a CCJ or instructing enforcement agents — the process can take several months. Your chosen firm should give you a realistic timeline once they have reviewed your case.
Will this damage my relationship with the debtor?
A professional firm will communicate firmly but appropriately, especially if you flag that the relationship matters to you. In many cases, debtors respond better to a formal third-party approach than to repeated calls from the creditor directly. The key is choosing a firm that understands the difference between pressure and harassment.
What happens if the debtor still refuses to pay even after a court judgment?
A CCJ gives you the legal right to enforce the debt, but it does not automatically result in payment. Enforcement options include instructing High Court Enforcement Officers, applying for an attachment of earnings order, or pursuing a charging order against the debtor's property. A good recovery firm will guide you through the most appropriate route for your situation.
Is it worth pursuing a small debt?
That depends on the size of the debt relative to the cost of recovery. Many firms have minimum debt thresholds — often around £500 to £750 for commercial debts. For smaller amounts, a solicitor's letter or formal demand may be enough to prompt payment without the need for full enforcement. It is worth having an initial conversation with a specialist to weigh up your options.
Can I still recover a debt if I do not have a written contract?
Yes, though it becomes more complex. If you can demonstrate that goods or services were provided and payment was agreed — through emails, messages, or other correspondence — you may still have a viable claim. An experienced firm will assess the strength of your evidence and advise on the best course of action.
What is the difference between a CCJ and a High Court Writ of Control?
A CCJ is a court order issued by the County Court confirming that money is owed. A Writ of Control is an enforcement tool issued by the High Court, which authorises High Court Enforcement Officers to attend the debtor's premises and take control of goods. Transferring a CCJ to the High Court for enforcement is a common and effective step when the debtor ignores a judgment.
Final Thoughts
Chasing unpaid invoices is frustrating, but staying passive is rarely the answer. The longer a debt sits unresolved, the lower your chances of recovering it in full.
Whether you are a business dealing with a commercial debt or an individual pursuing a private matter, getting professional help earlier rather than later puts you in a much stronger position. The right firm will not just chase — it will build a case, use the appropriate legal tools, and keep you informed throughout.
