Contractor Prosecuted For Ignoring An HSE Prohibition Notice

What’s happened?

A contractor in North London was recently prosecuted after continuing dangerous demolition and work-at-height activities despite being served with a prohibition notice by the Health and Safety Executive (HSE). The HSE described the behaviour as showing “complete contempt” for worker safety. The contractor later failed to attend court, which led to a warrant for his arrest and police detention following local intelligence.

He pleaded guilty to breaching a prohibition notice under section 33 of the Health and Safety at Work etc. Act 1974 and was sentenced to 20 weeks’ imprisonment suspended for 18 months, ordered to complete 200 hours’ community service, and required to pay costs of £12,151.

Why this case matters?

A prohibition notice is one of the most serious enforcement actions an inspector can issue. It requires an activity to stop immediately where there is an imminent risk of serious personal injury. Work must not restart until the specific hazards have been identified and rectified.

Ignoring such a notice not only endangers workers and the public but also exposes the business and individuals to criminal prosecution, financial penalties, damaged reputation and, in extreme cases, custodial sentences.

Lessons for businesses and clients

It’s important to ensure you vet contractors thoroughly. Check risk assessments, method statements, insurances, qualifications and accreditations (including SSIP and other relevant schemes) before appointment.

Contractors might not always volunteer full details of past incidents. Ask direct questions and verify responses.  Consult the HSE enforcement database to see whether a contractor has received improvement or prohibition notices or been prosecuted in the past five years.

Even if a contractor has had prior issues, they don’t necessarily need to be overlooked. Instead look for clear evidence of corrective measures and ongoing improvements rather than dismissing the matter.

Monitor performance. Ongoing oversight and site supervision are essential to ensure work remains compliant with health and safety requirements.
