Christopher Shaw, also known as Chris Parker, and trading as SOS Express Plumbing, attended the woman’s home in Headingley, Leeds, between 9 and 15 October 2019, where he was hired to carry out gas work.

Shaw had been assisting the woman with general plumbing needs for a number of years and told her he fitted the water heater in her bathroom.

As a result of this, the woman believed Shaw was able to work on gas appliances. At the request of the woman, who was 81 at the time, he removed an existing gas boiler and installed a new combination boiler at a total cost of £1,157.

An investigation by the Health and Safety Executive (HSE) found Shaw was not registered with the Gas Safety Register (GSR), a legal requirement while carrying out gas work. Shaw’s work at the woman’s home was subsequently investigated by GSR, which identified several issues. Some of these issues were deemed as ‘at risk,’ meaning they could be a danger to life or the property in the future.

Shaw had previously been prohibited from carrying out gas work by HSE and had subsequently been investigated and prosecuted for similar illegal gas work, resulting in a custodial sentence in 2015.

He pleaded guilty to breaching Section 3(1) of the Health & Safety at Work etc Act 1974, Section 33(1)(g) of the Health & Safety at Work etc Act 1974 and Regulations 3(1) and 3(3) of the Gas Safety (Installation and Use) Regulations 1998. Shaw was sentenced to 16 months in prison at Leeds Crown Court on 9 February 2023.

HSE inspector Darian Dundas said: “While checks could have been made with Gas Safe Register to identify whether Mr Shaw was registered and competent to carry out the gas works prior to any work being undertaken, Mr Shaw knew that he was not allowed to do this work.

“The carrying out of illegal gas works will not be tolerated and will be investigated fully with offenders being brought to justice.”
