Prohibition Notice? 12 Things to Do in the First 48 Hours: A Guide for UK and Global Businesses

If an inspector has just handed you a prohibition notice, an improvement notice, or both, you are in one of the most uncomfortable moments a business owner or operations leader can face. Work has stopped. People are watching. The clock is ticking. Insurance, contracts, reputation and personal liability all hinge on the next few decisions.

This guide is for the directors, HR leaders, facilities managers, contract holders, and international heads of operations who need clarity in those first 48 hours. Below are the 12 essential things to do, in roughly the order they matter, when an HSE enforcement notice lands. The objective is calm, defensible action that protects your people, your business and your standing with the regulator.

1. Understand Exactly Which Notice You Have Received

The first task is the simplest, and the one most often skipped under pressure. Read the notice carefully and confirm exactly which type you are dealing with:

• A prohibition notice stops specified work activities immediately, or by a stated time, because the inspector believes there is a risk of serious personal injury. It is the more serious of the two
• An improvement notice requires you to remedy a contravention of health and safety law by a set deadline, usually at least 21 days, but allows work to continue in the meantime
• An inspector can serve both following the same visit, addressing different issues

The HSE's enforcement policy sets out the formal definitions. Many businesses misread a prohibition notice as advisory, or treat an improvement notice with insufficient urgency. Both mistakes are costly.

2. Stop the Work Immediately if a Prohibition Notice Says So

A prohibition notice is legally binding from the moment it takes effect. If it states "immediate," then the activity must cease immediately. Continuing the prohibited activity, even briefly, is a criminal offence and dramatically worsens your position.

The first practical step is to make sure every supervisor, contractor, and operative on the relevant site understands what has stopped, why, and what they are still allowed to do. Visible communication, in person and in writing, is essential.

3. Secure the Notice, the Scene and the Evidence

Treat the notice itself, and the work area it refers to, as if they will be examined again. That means:

• Keeping the original notice safe and making copies
• Photographing the work area, equipment, signage and any visible defects
• Preserving CCTV, time-stamped photographs, and access logs
• Logging the inspector's name, badge number, time of visit and what was said
• Securing relevant documents: risk assessments, method statements, training records, accident book, maintenance records, and contractor files

This is where well-maintained health and safety software becomes invaluable. The businesses that recover fastest from enforcement notices are nearly always the ones that already had auditable records in one place.

4. Call Your Competent Person or Consultancy First, Then Your Lawyer

You need two perspectives quickly: someone who understands health and safety operationally, and someone who understands the legal consequences. The order matters. A good competent person or experienced health and safety consultants will help you read the notice technically, identify the practical fixes, and frame the engagement with the regulator. A lawyer with health and safety experience then handles the formal exposure, appeals, and any criminal investigation aspect.

Tackling the legal angle without operational input usually produces defensive paperwork. Tackling the operational angle without legal input can prejudice your position. You need both, in parallel.

5. Map Out the Deadlines and the Compliance Schedule

Every notice has dates. Miss them and the situation escalates fast. Note in writing:

• The effective date and time of any prohibition
• The compliance deadline on an improvement notice
• The 21-day appeal window for both types
• Any internal deadlines for board reporting, insurance notification, and contractual obligations to customers

Put these into your project management or health and safety consultants and software platform with named owners. Verbal commitments and informal email reminders are not sufficient at this stage.

6. Notify Your Insurer Promptly

Most employer's liability, public liability and management liability insurance policies require prompt notification of regulatory action. Failing to notify can void cover at exactly the moment you need it most.

Your broker or insurer is also a useful source of practical advice. They have seen enforcement situations many times before and can guide both your response and your communications.

7. Brief the Board and Senior Leadership the Same Day

Directors carry personal responsibility under UK health and safety law. The Health and Safety Executive can, in serious cases, prosecute directors and senior managers under section 37 of the Health and Safety at Work etc. Act 1974.

Brief the board the same day, in writing, with the facts of the notice, what has been done, what is being done next, and what decisions are needed. Hold a follow-up board review when the response plan is ready. Treating the notice as "an operational matter" rather than a board-level event is a classic mistake.

8. Decide Whether to Appeal, and Move Within 21 Days

You have 21 days from the date of service to appeal a prohibition or improvement notice to an employment tribunal. The grounds available include that the notice was not validly served, the contravention has not occurred, or the steps required are not reasonably practicable.

An appeal against a prohibition notice does not automatically suspend it. An appeal against an improvement notice does suspend it until the appeal is decided. That difference is important for planning. Take advice early; the decision to appeal should be a strategic one, not an emotional one.

9. Build a Defensible Compliance Action Plan

Whether or not you appeal, you need a documented plan that demonstrates how the underlying issue is being addressed. A strong plan typically includes:

1. A clear restatement of the contravention identified by the inspector
2. The immediate actions taken to stop the risk
3. The root cause analysis (not just the surface fix)
4. The corrective and preventive actions, with named owners and dates
5. The verification step: who will check the fix actually worked
6. The review point: how the wider system will be improved

10. Communicate Carefully With Staff, Contractors and Customers

The way you communicate during an enforcement event matters. Be factual, calm and consistent. Avoid speculation about blame or outcomes.

• Staff: acknowledge what has happened, what you are doing, and what you need from them
• Contractors: confirm what work is paused and what continues, in writing
• Customers and clients: decide who needs to know, what they need to know, and who delivers the message
• The wider organisation: if multi-site, consider whether the issue could exist elsewhere and act accordingly

Poor internal communication can convert a single-site notice into a broader cultural problem. The same is true in reverse: a well-handled enforcement event can actually strengthen workforce trust in leadership.

11. Use the Notice as a Trigger for a Full Audit

A prohibition or improvement notice is rarely about a single isolated fault. It is usually the visible tip of a wider gap in the management system. The smartest businesses respond by commissioning a full, independent health and safety audit of the affected site, and often the wider business.

Auditors look at the controls around the specific issue, the management arrangements that allowed it, and the cultural patterns that may produce similar issues elsewhere. Pairing the audit with a clear workplace health and safety audit framework gives the board confidence that the response is comprehensive, not cosmetic.

12. Use the Recovery to Build Lasting Resilience

The final, and arguably most important step: do not waste the recovery. Once the immediate crisis has been resolved, use the experience to strengthen the wider system. That typically means:

• Updating your health and safety policy and procedures
• Strengthening health and safety training at supervisor and operative level
• Embedding more effective monitoring and review cycles
• Aligning your management system with ISO 45001, the international benchmark
• For multi-jurisdiction groups, having international health and safety consultants align controls across the UK and overseas equivalents, including French, German, Italian, Dutch and US regimes supported by EU-OSHA, the ILO and ISO 45001:2018

A notice is a hard moment. Handled well, it can become a turning point that improves the business for years.
