A County Court Judgment is a significant milestone in commercial debt recovery. But winning in court is only half the battle. If the debtor refuses to pay voluntarily, you need to enforce it — and that is where the right enforcement tool makes all the difference.
An attachment of earnings order (AEO) is one of the most reliable post-judgment enforcement mechanisms available to UK creditors. Rather than chasing the debtor directly, it instructs their employer to deduct money from their wages before it even reaches them. Here is how it works, when to use it, and what UK creditors need to know in 2026.
What is an Attachment of Earnings Order?
An attachment of earnings order is a court order, issued under the Attachment of Earnings Act 1971, that compels an employed debtor’s employer to make regular deductions from their wages and pay those amounts directly to the creditor (or to the court, which then distributes them).
The key point is that it removes the debtor from the payment chain entirely. You are not relying on the debtor’s good faith or memory. The employer becomes the collection agent, and they are legally obliged to comply.
For debts up to £5,000, applications are dealt with by the County Court. For larger debts, or where the creditor holds a High Court judgment, High Court enforcement officers (HCEOs) can be instructed instead — a faster and often more effective route.
The Legal Foundation: County Court Act 1984 and the 1971 Act
The Attachment of Earnings Act 1971 is the primary statute governing AEOs in England and Wales. It sets out who can apply, on what grounds, and how the protected earnings rate is calculated. The County Courts Act 1984 supplements this with provisions covering judgment enforcement more broadly.
Scotland and Northern Ireland have separate frameworks. In Scotland, earnings arrestment fulfils a similar function but operates under different rules. This article covers England and Wales only.
When Can You Apply?
To apply for an attachment of earnings order in England and Wales, you must:
- Hold an unsatisfied County Court Judgment (CCJ) against the debtor
- Establish that the debtor is employed at the time of application
- Apply on form N337 to the County Court that issued the judgment
You cannot use an AEO against a debtor who is self-employed, unemployed, or a director drawing dividends rather than a salary. In those cases, different enforcement tools — such as a third party debt order, a charging order, or High Court enforcement — may be more appropriate.
How the Court Sets Deduction Amounts
Once an application is made, the court sends a questionnaire (form N56) to the debtor, asking for details of their income and outgoings. Based on this, the court sets two figures:
- The normal deduction rate: the amount to be deducted each pay period
- The protected earnings rate: the minimum take-home pay the debtor must retain
If the debtor’s earnings fall below the protected earnings rate in a given period (due to sick leave, reduced hours, or overtime variance), the employer makes no deduction that period. This can slow recovery significantly for debtors on variable or low incomes.
The Employer’s Obligations
Once served with an AEO, the employer has clear legal duties:
- Begin making deductions from the debtor’s next available pay period
- Remit the deducted amounts to the court on the schedule specified in the order
- Notify the court if the debtor leaves employment or changes their pay arrangements
- Maintain records of all deductions made
Employers are entitled to deduct £1 per payment as an administrative handling fee. This is a statutory entitlement under the 1971 Act and cannot be waived by the order.
Employers who fail to comply risk being held in contempt of court. In practice, AEO compliance rates among employers are high — few are willing to risk court sanction over an employee’s personal debt.
Priority AEOs vs Non-Priority AEOs
Not all attachment of earnings orders are equal. The 1971 Act distinguishes between priority and non-priority orders:
Priority orders cover maintenance payments, fines, and certain council tax debts. These take precedence in the deduction queue and are paid first from available earnings above the protected rate.
Non-priority orders cover commercial and personal debts repaid via CCJ enforcement. If a debtor has multiple non-priority AEOs against them, the court consolidates them into a single consolidated attachment of earnings order (CAEO) to avoid over-deduction.
Commercial creditors pursuing trade or invoice debts will typically be dealing with non-priority orders. This means recovery can be delayed if the debtor already has a consolidation order running for other debts.
What Happens if the Debtor Changes Jobs?
This is the most common practical challenge with AEOs. The order is attached to the debtor’s current employment, not to the debtor personally in perpetuity. If they change jobs, the order is suspended until their new employer is identified and notified.
As the creditor, you (or your debt recovery agent) bear responsibility for tracing the new employer and applying to redirect the order. Courts do not do this automatically. Debtors who are aware of this sometimes use job changes as a delaying tactic.
Where employment instability is a concern, it may be worth considering whether a charging order against property or other assets offers a more durable long-term security.
AEOs vs Other Post-Judgment Enforcement Tools
Attachment of earnings orders sit within a wider toolkit of post-judgment enforcement options. Choosing the right tool depends on the debtor’s circumstances:
- AEO: Best where debtor is employed with stable income. Gradual, reliable, passive recovery once set up.
- Third party debt order: Best where debtor has money in a bank account. Fast but requires locating the account.
- Charging order: Best where debtor owns property. Provides long-term security; enforced on sale or via an order for sale.
- Writ of control (High Court enforcement): Best for swift enforcement against assets. Requires transfer of judgment to High Court. Often the fastest option for debts over £600.
- Winding up petition: Best for company debtors refusing to pay. Triggers liquidation proceedings if debt exceeds £750.
Many commercial creditors use a combination: for example, a High Court writ for immediate pressure while a charging order is applied for as long-term security.
Using an AEO Against a Personal Guarantor
One scenario where AEOs are particularly relevant for commercial creditors is recovery from a personal guarantor. If a limited company debt is guaranteed by a director or individual, and that individual is employed (perhaps by a different company), an AEO can be applied for against their wages once a CCJ is obtained against them personally.
This is a route many creditors overlook. If your original contract included a personal guarantee, check whether the guarantor is now in employment before writing off the debt or pursuing only the company.

What is an attachment of earnings order in UK law?
An attachment of earnings order (AEO) is a court order that directs a debtor’s employer to deduct a fixed amount from the debtor’s wages or salary each pay period and send it directly to the creditor. It is governed by the Attachment of Earnings Act 1971 and is issued by the County Court after a creditor applies following an unsatisfied County Court Judgment (CCJ). The order bypasses the debtor entirely, making it one of the more reliable post-judgment enforcement tools available to UK creditors.
Do I need a CCJ before I can apply for an attachment of earnings order?
Yes. An attachment of earnings order can only be obtained once you hold a County Court Judgment (CCJ) against the debtor and that judgment remains unsatisfied. You must also show that the debtor is an employed person at the time of application — the order cannot be used against someone who is self-employed, a sole trader, or unemployed. If the debtor changes employer, you must notify the court so the order can be redirected.
What is the protected earnings rate and how does it work?
The protected earnings rate is the minimum net income a debtor must retain each week or month after deductions. The court sets this figure based on the debtor’s personal circumstances, including household expenses and dependants. An employer cannot deduct money that would take the debtor below this threshold, even if a deduction is scheduled. This means actual payment amounts can fluctuate in lower-income cases, and recovery may be slower than expected.
How long does it take to recover the debt through an AEO?
Recovery timescales vary considerably depending on the debtor’s salary, the protected earnings rate set by the court, and the total amount owed. For smaller debts with a well-paid debtor, recovery might take three to twelve months. Larger debts or lower wages can extend this to several years. Unlike a writ of control (bailiff enforcement), an AEO is a gradual mechanism rather than an immediate recovery tool.
Can a debtor escape an attachment of earnings order by changing jobs?
Not permanently. If the debtor leaves employment, the order is suspended but not discharged. As the creditor, you or your solicitor must trace the debtor’s new employer and apply to the court to redirect the order. This does create enforcement gaps, particularly if the debtor moves between employers frequently or takes temporary or cash-in-hand work. In those situations, combining an AEO with other enforcement methods — such as a third party debt order or a charging order — is often more effective.
Is an attachment of earnings order suitable for recovering business debts?
An AEO is best suited to recovering personal debts from individual debtors who are in employment — for example, a sole trader or personal guarantor who is also employed. It cannot be used against a limited company. For recovering commercial debts from a company, creditors typically pursue High Court enforcement, winding up proceedings, or a charging order against company property instead. A debt recovery specialist can advise on the most appropriate route based on the debtor’s structure and assets.
What happens if an employer ignores an attachment of earnings order?
An employer who receives a valid attachment of earnings order is legally obliged to comply. Failure to make deductions, or failure to notify the court of the debtor’s employment status, can result in the employer being fined or held in contempt of court. Employers may also charge a small administrative fee (currently £1 per deduction) to cover processing costs. In practice, most employers comply promptly once they receive the official court order.
