• Worker struck by reversing road-sweeper
• Family describes Robert Morris as “the centre of our world”
• HSE guidance is available on safe use of vehicles on site

A construction company that specialises in road resurfacing in London has been fined £546,000 after one of its employees was killed by a reversing road-sweeper.

Robert Morris, 48, was working on the resurfacing of Pemberton Road in Haringey for Marlborough Highways Limited on 30 May 2022. A colleague was at the wheel of the vehicle and Robert was struck while it was reversing.

A joint investigation was launched between the Health and Safety Executive (HSE) and the Metropolitan Police. The police submitted evidence to the Crown Prosecution Service (CPS) leading to a separate prosecution, which resulted in the driver being given a suspended prison sentence.

The HSE investigation identified a number of failings. There was no segregation between people and moving vehicles on site and a banksman was not used when the road sweeper reversed and struck Mr Morris. The traffic management systems in place at the site were inadequate and unsafe, placing employees and members of the public at risk of serious injury and death.

The majority of construction transport accidents result from the inadequate segregation of pedestrians and vehicles. This can usually be avoided by careful planning, particularly at the design stage, and by controlling vehicle operations during construction work.

The safe use of vehicles on construction sites: A guide for clients, designers, contractors, managers and workers involved with construction transport – HSE provides detailed guidance on the importance of a safe site and the segregation of people and vehicles.

Marlborough Highways Limited of Woolf House Eagle Way, Chelmsford Garden, Chelmsford pleaded guilty to Sections 2(1) and 3(1) of the Health and Safety at Work etc. Act 1974 at the first opportunity. The company was fined £546,000 , with full costs awarded in the sum of £6,028, at City of London Magistrates’ Court on 3 October 2025.

In the separate CPS case, Jamie Smith, 46, from Essex, who was also an employee of the company, was prosecuted for an offence of causing death by careless driving contrary to section 2B of the Road Traffic Act 1988. He pleaded guilty and in February 2024, at Wood Green Crown Court, he was sentenced to a six-month custodial sentence, suspended for two years, and disqualified from driving for one year.

HSE principal inspector James Goldfinch said: “Our thoughts are with Robert’s family, described by his widow as ‘the centre of our world’. She says his children are ‘sad and angry and cheated of so much of their future’.

“Robert was entitled to return home safely from work to his family but the lack of segregation of vehicles and pedestrians by Marlborough Highways Limited meant he did not.

“This was a case where appropriate controls had been identified but were not being implemented on site.”

The prosecution was brought by HSE’s Enforcement Lawyer Samantha Wells, with the assistance of Paralegal Melissa Wardle.

• Workers put at risk of serious injury.
• Inspector slams contractor for showing “complete contempt” for workers’ safety
• HSE guidance is available on safe working from height and demolition.

A London contractor has been given a suspended prison sentence after risking the lives of workers and ignoring action taken by Britain’s workplace regulator.

The Health and Safety Executive (HSE) ordered Mohammed Mehdi Ali to stop working at a construction site in Willesden on 7 September 2018. Inspectors visited the Willesden Lane site and found unplanned, unsupervised and unsafe work was putting people at serious risk of injury.

Workers had been identified working on the roof area where they were at serious risk of falling from a height as no measures to protect them were in place. Unplanned and unsafe demolition work had also left the building structure at risk of collapse.

Despite the prohibition notice being served against him, Mr Ali ignored it and the work continued as before, putting the lives of those working on the site at risk. Mr Ali, of Barn Hill in Wembley, also failed to turn up at court to face justice in 2021 and as a result a warrant was issued for his arrest. It was only thanks to intelligence from the local community that the police arrested him and the court proceedings could finally resume. He has now been given a suspended 20-week custodial sentence and ordered to complete 200 hours of unpaid work.

Not only did the HSE investigation find that Mr Ali disregarded the prohibition notice, but also that he failed to put in place measures to ensure the health and safety of people at his construction site.

The law requires employers to carry out their legal duty to protect persons’ health and safety at the workplace by ensuring that construction work is adequately planned, managed, and monitored and appropriately supervised.

Falls from height remains one of the leading causes of workplace injury and death and HSE has detailed guidance on working safely at height. In law, demolition work is treated the same as any other construction work. Workers must be supervised and follow safe working practices. HSE guidance on demolition is available.

Mr Ali pleaded guilty to committing an offence under s33(1)(g) of HSWA by breaching a prohibition notice and continuing to carry on the work without suitable and sufficient measures in place thereby exposing his workers to serious risk of personal injury. He was sentenced to 20 weeks imprisonment, suspended for 18 months and must complete 200 hours of unpaid work as well as 10 days of rehabilitation. He was also ordered to pay £12,151 in costs at a hearing at Westminster Magistrates’ Court on 7 October 2025.

HSE inspector Saif Deen said: “Mr Ali not only ignored HSE and the criminal justice system, he showed complete contempt for the safety of workers.

“The law requires employees to ensure the health and safety of persons at their workplace. Employers have a responsibility to ensure that everyone on a building site is safe.

“We will not hesitate to take action against those who fail to comply with HSE enforcement and continue to put their workers at risk.

“Working at height remains one of the leading causes of workplace death and injury.

“We would like to thank the local community for ensuring justice was done, which helps to keep people safe.”

This prosecution was brought by HSE enforcement lawyer Alan Hughes and paralegal officer David Shore.

• Two workers were on first floor when collapse happened.
• “Lucky nobody was killed”, says HSE inspector.
• HSE guidance is available.

A London construction company has been fined £50,000 after four men were injured – two seriously – when the first floor of a house collapsed during building works.

Aryn Stones Ltd had been contracted to build a new domestic property in Hampstead. On 31 May 2022, remedial works were being carried out on a partially built beam-and-block floor, when it collapsed, taking two of the workers down with it.

The two men include a welder, who is now 62, and a 31-year-old bricklayer. They both sustained life-changing injuries, while two other men who were standing at ground level were injured by falling concrete.

Work on the build began in March 2021 but by February the following year, engineers who inspected the property identified errors with the connections of the structural steel beams. This prompted the remedial works that led the structure to collapse. That came about when the welder was using an oxyacetylene torch to cut a steel beam supporting the first floor. However, at the same time, another worker had been removing some Acrow props that were supporting the beam.

An investigation by the Health and Safety Executive (HSE) found that Aryn Stones Ltd had failed to ensure the structure did not collapse while it was in a state of temporary weakness. The company also failed to put any measures in place to manage the temporary remedial work being carried out on the steel connections. They also failed to take all practicable steps to prevent danger to any person while the building was in a temporary state of weakness.

HSE guidance on managing health and safety in construction and the management of temporary works is available.

Aryn Stones Ltd, of Percy Road, London were found guilty of breaching Regulation 19(1) of the Construction (Design and Management) Regulations 2015. The company was fined £50,000 and was ordered to pay £39,000 costs following a two-day trial before City of London Magistrates’ Court on 18 June 2025.

After the hearing, HSE inspector Lucy Ellison-Dunn said: “Although two men were seriously injured, it was lucky nobody was killed.

“This was a completely avoidable incident had a system for the management of temporary works been in place. The company should have taken precautions to protect people from the risk of collapse.

“Everyone working in construction has a responsibility to ensure that everyone on a building site is safe.”

The investigation was also carried out by HSE inspector Alexander McIlwraith.

This prosecution was brought by HSE enforcement lawyer Samantha Crockett and supported by HSE Paralegal Officer Sarah Thomas.
