Scaffold collapse on busy London high street leaves two pedestrians seriously injured

A construction company and its director have been ordered to pay fines and costs totalling more than £30,000 after a scaffold tower collapsed onto a busy London high street, trapping two pedestrians beneath it and leaving them with serious injuries.
The incident on Putney High Street on 19 July 2023 has prompted fresh warnings from safety regulators about the importance of correct scaffold assembly and wind-load management — lessons that carry significant weight for principal contractors and site supervisors across the UK construction sector.
For principal contractors and site supervisors, the message from Putney is clear: failing to assess wind-load risks can have catastrophic consequences.

Fines handed down at Westminster Magistrates’ Court
Add Prop Limited was fined £20,000 and ordered to pay £7,000 in costs during a recent hearing at Westminster Magistrates’ Court. The company’s director, Atif Riaz, received a personal fine of £1,730 and was ordered to pay a further £1,730 in costs.
The Health and Safety Executive (HSE) investigated the collapse and found that the scaffold tower had been incorrectly assembled. Investigators also discovered that the structure had been covered in sheeting, which acted as a sail in windy conditions — significantly increasing the load on the tower.
The HSE concluded that Add Prop Limited, which was acting as principal contractor for a conversion project at the site, had failed to ensure the scaffold could withstand expected wind loads. Riaz had been responsible for supervising the work.
Prior prohibition notice ignored
The court heard that the company had already received a prohibition notice from authorities before the collapse — a formal warning typically issued when workplace activities involve a risk of serious personal injury. Despite this, the scaffold was not constructed or secured to the required safety standards for wind resistance and structural integrity.
The HSE said the incident was entirely preventable had proper procedures been followed.
The HSE’s message is clear: the Putney collapse was entirely preventable with proper procedures. Yet many construction firms lack the documents needed to demonstrate compliance with UK regulations.

Wider context of construction safety
The sentencing comes amid a series of serious incidents at construction and renovation sites across England. On 9 July 2026, a man in his 30s died after falling from a renovation project in Mayfair managed by Structure Tone International. The company said no health and safety violations were involved, but a police investigation remains ongoing.
The following day, a worker employed by BSN Group Construction died after a fall at Birmingham Children’s Hospital. The back-to-back fatalities have intensified scrutiny of safety protocols and regulatory oversight within the construction sector, reinforcing the message that failures in basic structural safety — such as those seen on Putney High Street — can have devastating consequences.
