When Things Go Wrong: Understanding Liability, Insurance, and Wage Deductions After a PA's Mistake

When Things Go Wrong: Understanding Liability, Insurance, and Wage Deductions After a PA's Mistake

Hiring a personal assistant involves an inherent degree of trust. You are inviting someone into your home, delegating tasks that may involve your property, your finances, your vehicle, or your family members — and accepting that they will exercise judgement on your behalf. In the vast majority of cases, that trust is well placed. But mistakes happen, and when they do, private employers are frequently unsure what their legal position actually is.

The question of who bears responsibility for a PA's error is not straightforward, and the answer depends on the nature of the mistake, the circumstances in which it occurred, and the contractual and insurance arrangements already in place.

The Doctrine of Vicarious Liability

Under English law, an employer can be held legally responsible for the wrongful acts of an employee carried out in the course of their employment. This principle — known as vicarious liability — exists in both contract and tort, and it applies to household employers just as it does to commercial ones.

In practical terms, this means that if your PA accidentally damages a visitor's property whilst performing their duties, causes injury to a third party, or makes an error that results in financial loss to someone else, you as the employer may be exposed to a claim. The fact that you did not personally commit the act offers limited protection if the PA was acting within the scope of their role at the time.

This is not a theoretical risk. Courts have found household employers liable in cases involving accidents during driving duties, harm caused during childcare, and damage to neighbouring properties. The scope of vicarious liability has, if anything, been broadened by recent case law.

The Role of Household Insurance

The most effective safeguard against liability arising from a PA's actions is adequate insurance cover. Standard home contents and buildings insurance policies frequently exclude liability arising from the employment of domestic staff, and many household employers do not realise this until they attempt to make a claim.

You should ensure that your insurance arrangements include:

• Employers' liability insurance: This is a legal requirement if you employ staff, and it covers claims made by an employee who suffers injury or illness as a result of their work. Failure to hold a valid employers' liability policy is a criminal offence, with fines of up to £2,500 per day.
• Public liability insurance: This covers claims from third parties — visitors, neighbours, or members of the public — who suffer loss or injury as a result of your PA's actions in the course of their duties.
• Personal liability insurance: Some household policies include this, but the scope varies significantly. Check whether your policy extends to the actions of domestic employees.

If your PA drives as part of their role, their motor insurance must reflect business use. A personal policy without business cover may be invalid in the event of an accident during working hours, leaving you exposed.

Reviewing your insurance arrangements annually — and whenever the scope of your PA's duties changes significantly — is a prudent habit.

Can You Deduct the Cost of a Mistake from Their Wages?

This is one of the most common questions raised by household employers following an incident, and the answer is firmly constrained by law.

The Employment Rights Act 1996 prohibits deductions from a worker's wages unless one of the following conditions is met:

1. The deduction is required or authorised by statute (for example, income tax or National Insurance).
2. The deduction is authorised by a written provision in the employee's contract, which the employee has been given prior to the deduction being made.
3. The employee has given their prior written consent to the specific deduction.

A clause permitting deductions for accidental damage or errors must be included in the employment contract before any incident occurs. A clause inserted after the fact, or verbal agreement obtained after a mistake has been made, will not be lawful. Even where a valid contractual clause exists, the deduction must be reasonable and proportionate — a clause permitting you to recover the full cost of a significant accidental loss from a modest salary is unlikely to withstand scrutiny.

Attempting to withhold wages without lawful authority, even in response to genuine financial loss, can result in an employment tribunal claim for unlawful deduction of wages. Tribunal claims of this nature are relatively straightforward for a claimant to bring, carry no fee, and frequently succeed.

Handling the Situation Without Escalation

When a mistake occurs, the manner in which you respond will influence both the outcome and the ongoing working relationship. The following approach is generally advisable:

Remain measured. A heated reaction in the immediate aftermath of an incident rarely produces a constructive result. Allow time for the situation to be assessed before initiating any formal conversation.

Establish the facts. Was the PA acting within their duties at the time? Was the error the result of negligence, or was it a genuine accident? Was there any relevant training, instruction, or guidance that they failed to follow? The answers to these questions will inform how you proceed.

Use your disciplinary procedure proportionately. Where a mistake arises from genuine negligence or a failure to follow reasonable instructions, it may be appropriate to address this through your disciplinary process. A first instance of carelessness would typically warrant a verbal or written warning rather than dismissal, unless the consequences were severe.

Consider whether systemic issues contributed. Employers are not immune from responsibility. If the PA was undertaking a task without adequate training, equipment, or supervision, you may bear some responsibility for the outcome.

Why Contracts and Insurance Are Your First Line of Defence

The clearest lesson from this area of law is that prevention is considerably less costly than remedy. A well-drafted employment contract, prepared before your PA begins work, should include:

• A clause addressing deductions from wages in clearly defined circumstances.
• Clear job descriptions and boundaries of authority, particularly where financial transactions or driving are involved.
• Provisions governing the use of your property, vehicle, and financial accounts.

Paired with comprehensive household insurance that genuinely covers domestic employment, these measures transform a potentially costly incident into a manageable one. Without them, even a relatively minor mistake can expose a private employer to disproportionate financial and legal consequences.

If you are uncertain whether your current contract and insurance arrangements are adequate, taking professional advice before a problem arises is invariably the more sensible course.
