• Adam’s Building Construction Ltd built an extension over gas pipework and a boiler flue without relocating them, despite repeated warnings
• The gas installation was found to be immediately dangerous, forcing Northern Gas Networks to cut off the property’s gas supply
• The company failed to comply with an HSE Improvement Notice, and its director failed to cooperate with the HSE investigation

A Yorkshire-based building company and its director have been sentenced after botched building work on a home extension compromised gas safety and put the lives of a homeowner and her two children at risk.

Adam’s Building Construction Ltd had been hired by the homeowner to build an extension at the rear of her property in Bradford. Construction began in January 2024, but the extension was built over the top of the existing gas service pipework, and without repositioning the flue serving the property’s gas boiler. This exposed the family to the risk of gas leaks, fire, explosion and carbon monoxide poisoning.

An investigation by the Health and Safety Executive (HSE) found that on 22 May 2024, a Building Control Inspector from the City of Bradford Metropolitan Council attended the property and discovered that the boiler flue was terminating inside the extension. He contacted Northern Gas Networks, who found the gas installation to be immediately dangerous, with the boiler still in operation and the flue discharging into the extension. The gas supply had to be cut off, leaving the residents without gas for several weeks and costing them around £4,000 to put right.

The investigation also found that Adam’s Building Construction Ltd had been warned several times by local authority Building Control Inspectors during the works that the gas pipework and flue needed to be properly relocated. The company’s sole director, Mohammed Adam Azhar, was unable to show HSE inspectors that his company had prepared construction phase plans for any of its building work, which was carried out exclusively for domestic clients.

This led HSE to serve an Improvement Notice requiring the company to put in place a system for producing written construction phase plans for projects where it was the principal contractor. The company subsequently failed to comply with that notice, an offence under Section 33(1)(g) of the Health and Safety at Work etc. Act 1974. Mr Azhar also personally failed to provide relevant information to the investigation when required to do so by the HSE Lead Inspector, an offence under Section 33(1)(e) of the Act. The court heard that neither the company nor Mr Azhar continue to work in the construction trade.

Adam’s Building Construction Ltd, of Leeds Road, Bradford, pleaded guilty to breaching Section 3(1) and Section 33(1)(g) of the Act. On 7 August 2026 at Leeds Magistrates Court, the company was fined a total of £10,000 and ordered to pay costs of £4,263.

Mohammed Adam Azhar, of Intake Road, Bradford, pleaded guilty to breaching Section 37(1) and Section 33(1)(e) of the Act. He was fined a total of £1,000 and ordered to pay a victim surcharge of £400.

HSE Inspector David Beaton said:

“This was a tragic accident waiting to happen. The failure on the part of the company and its director to properly plan this building work, and to make suitable arrangements for relocating the gas pipework and appliances, could have easily had fatal consequences for the family living in the property.

“Those failures were compounded by the further failures to comply with an HSE Improvement Notice, and to provide relevant information to assist our investigation.

“Everyone in control of domestic building work must ensure that a suitable and sufficient construction phase plan is in place before building work commences, so that no-one faces the kind of risks this family were exposed to.”

This Prosecution was brought by HSE Enforcement Lawyer Arfaq Nabi and supported by Paralegal Officer Henrietta Ruthven.

• Worker sustained serious injuries when his foot was trapped in machinery.
• Company had failed to prevent access to dangerous parts.
• HSE guidance is available.

A Yorkshire animal feed manufacturer has been fined £500,000 after a worker lost part of his foot when it was entangled in machinery.

William Thompson (York) Limited pleaded guilty after failing to prevent access to a rotating auger – a tool consisting of a central shaft with a blade wrapped around it – which is designed to transport excess feed away from a press.

The 41-year-old had been working as a supervisor at the company’s Jubilee Mill site in York on 14 November 2023. At the time of the incident, the man had been trying to resolve a maintenance issue with the machinery. However, he was able to open the press while its parts remained in operation at significant speed. His foot became entangled in the rotating auger and he sustained injuries so serious he remained in hospital for a period of six weeks.

An investigation by the Health and Safety Executive (HSE) found that William Thompson (York) Limited failed to prevent access to dangerous parts of the machinery and also to carry out a suitable risk assessment of the work being done.

HSE guidance states employers must take effective measures to prevent access to dangerous parts of machinery. This will normally be by fixed guarding but where routine access is needed, interlocked guards may be needed to stop the movement of dangerous parts before a person can reach the danger zone. Further guidance can be found here: Provision and Use of Work Equipment Regulations 1998 (PUWER) – HSE.

William Thompson (York) Limited, of Main Street, Malton, North Yorkshire, pleaded guilty to breaching Section 2(1) of the Health and Safety at Work Act etc 1974. The company was fined £500,000 and ordered to pay £4,455 in costs at York Magistrates court on 18 November 2025.

HSE Inspector Shauna Halstead said: “This company’s failures resulted in a man sustaining life-changing injuries.

“Too many workers are injured or killed every year because of failures to guard dangerous parts of machinery.

“Companies must implement safe working practices when carrying out maintenance operations.

“We will not hesitate to take action against companies which do not do all they should to keep people safe when working with machinery.
