Unregistered gas installer sentenced for carrying out illegal gas work

An unregistered gas installer has been sentenced after carrying out illegal gas work at two houses in Cheshire.

The work was undertaken on several occasions between 2021 and 2023, resulting in a gas leak inside one of the properties, leaving one of the homeowners without a working appliance for an extended period.

The Health and Safety Executive (HSE) was alerted to Mr Williams by the Gas Safe Register following an inspection of the work carried out at one of the properties, which identified an installation was at risk. It soon became clear that the installer had also carried out work at another property, and that he had issued a Gas Safety Certificate using a false registration number.

The Gas Safety (Installation and Use) Regulations 1998 require those undertaking gas work to be Gas Safe registered and hold the relevant qualifications to demonstrate their competence. It is an offence under these regulations to falsely claim to be a Gas Safe registered engineer.

Members of the public are reminded that all gas work must be carried out by a Gas Safe registered engineer. The Gas Safe Register is the official list of gas businesses legally permitted to work on gas appliances in the UK. Anyone can check whether an engineer is registered by visiting www.gassaferegister.co.uk or calling 0800 408 5500.

Carrying out gas work without registration is illegal and potentially dangerous, as unqualified work can lead to gas leaks, fires, explosions, and carbon monoxide poisoning.

The sentencing hearing for Scott Anthony Williams was at Chester Magistrates’ Court on the 24 October 2025. Scott Anthony Williams of Galbraith Close, Congleton, pleaded guilty to seven separate breaches of the Gas Safety (Installation and Use) Regulations 1998. He was sentenced to a 12-month community order, requiring 240 hours of unpaid work. Costs of £2,000 were awarded along with a victim surcharge of £144.

HSE inspector Nicola Willcox said:

“This was a deliberate breach of gas safety legislation that put people at risk.

“All gas work must be undertaken by Gas Safe registered engineers. The public should always ask to see the gas engineer’s identification and check the registration number online to ensure it is valid.”

This prosecution was brought by HSE enforcement lawyer Julian White and paralegal officer Sarah Thomas. The investigation was supported by Sarah Ough and Natalka Heath, HSE Visiting Officers.

Man sentenced after carrying out illegal gas work

A Middlesbrough man has been given a suspended prison sentence after carrying out illegal gas work.

An investigation by the Health and Safety Executive (HSE) found Neil Burton carried out boiler services in a home in Stockton-on-Tees on two occasions, in May 2021 and April 2022. Although Burton had previously been on the Gas Safe Register, he had allowed his membership and qualifications to lapse. A subsequent review of the boiler identified defects which meant it was classed as a risk and a danger.

Burton, 41, also carried out work at a house in Middlesbrough in September 2022 and October 2023. These works included disconnecting a gas hob and installing a new one, as well as disconnecting a gas fire. As he had done previously, he carried out this work while not registered to do so. He had also been subject of previous action taken by HSE, when carrying out illegal gas work in 2015.

Neil Burton, of Harrogate Crescent, Middlesbrough, pleaded guilty to breaching Regulations 3(1) and 3(3) of the Gas Safety (Installation and Use) Regulations 1998. He was given a six-month prison sentence suspended for 12 months and ordered to complete 150 hours of unpaid work at Teesside Magistrates’ Court on 7 October 2025.

After the hearing, HSE Inspector Darian Dundas said:

“All gas work must be carried out by registered Gas Safe engineers to ensure the highest standards are met and to prevent injury or loss of life.

“The public should always ask to see a gas engineer’s identification and check their registration number online.”

Rogue gas fitter jailed for carrying out unsafe work

A rogue gas fitter from Norfolk has been jailed after carrying out unsafe gas work at a residential property while suspended from the Gas Safe Register.

Antony Clifton, from Wymondham, has been sentenced to 46 weeks in custody after he carried out unsafe gas work while falsely claiming to be a member of the Gas Safe Register. He worked at a home in Drayon, Norwich in January 2022, but there was a gas escape on the inlet to a cooker that had been fitted the day before by the 52-year-old.

An investigation by the Health and Safety Executive (HSE) found that Clifton had left the appliance in a condition where gas was leaking, and emergency repair work was required. Clifton had previously been served with a prohibition notice by HSE following unsafe gas work.

Further information and guidance on domestic gas health and safety is available.

Antony Clifton, a director of CS Appliance Repairs Limited, of Exige Way, Wymondham pleaded guilty to breaching Regulations 3(7) and 5(3) of the Gas Safety (Installation and Use) 1998 Regulations. He was sentenced to a total of 46 weeks in custody and was ordered to pay £1,000 costs at a hearing at Great Yarmouth Magistrates’ Court on 14 July 2025.

After the hearing, HSE inspector Martyn Webb said: “Antony Clifton knew that he was not registered and should not carry out any gas work.

“However, he showed a blatant disregard to this fact and his illegal actions meant the people living in that house could have been killed.

“Homeowners and tenants should check for Gas Safe registration before allowing work to commence on their appliances and refuse entry to individuals who cannot prove they are registered.

“All gas work must be done by a registered Gas Safe engineer to ensure the highest standards are met to prevent injury and loss of life.”

Suspended prison sentence for builder over gas safety failures

A builder has avoided an immediate spell behind bars after being convicted of carrying out gas work at a property in Berkshire when he was not qualified to do so.

Thomas Murray, who traded as Kerbgold Design and Construction Ltd, was given an eight-month prison sentence which was suspended for 18 months.

Reading Crown Court heard how Murray had been contracted to manage a large-scale renovation and extension of a property in Maidenhead in July 2018. The project involved significant gas work, including the installation of a gas boiler, relocation of a gas meter and the installation of associated pipework for both.

Further information and guidance on domestic gas health and safety is available.

However, the project over ran and the householders had to return to the property in January 2019, where they soon reported the smell of gas. Murray carried out a test which detected no gas leak.

As their concerns persisted, the homeowners contacted a Gas Safe Registered engineer to inspect the installation. The engineer found a gas leak and other faults within the installation. In addition, Cadent Gas, the gas supplier to the property, had never been notified about the relocation of the meter and pipework. The pipework leading to the meter was found to have been laid to incorrect depth and fittings suitable only for water pipework had been found to have been used throughout the installation.

An investigation by the Health and Safety Executive (HSE) found that although Murray arranged for a Gas Safe engineer to install the boiler, they had only connected the water plumbing and left the property due to concerns being raised. In a bid to allow the homeowners to access hot water and heating, Murray decided to undertake some of the gas work himself as a temporary fix.

Murray, of Heath End Road, Flackwell Heath, Buckinghamshire, pleaded guilty to breaching section 3(2) of the Health Safety at Work Act 1974 and was sentenced to eight months in prison, suspended for 18 months. He was also ordered to complete 250 hours unpaid work.

Speaking after the hearing, HSE inspector Karen Morris said: “In this case, Mr Murray was responsible for overseeing the gas work, which was not finished and had left householders and their neighbours at risk from the dangers and effects of leaking gas.

“To make matters worse, he decided to try and finish the job himself, despite not being competent to do so.

“His failures could have led to catastrophic and tragic consequences.

“We will not hesitate to prosecute builders who fail to ensure that gas work under their control is conducted safely using Gas Safe Registered engineers.”
