Unregistered gas fitter jailed for illegal and unsafe gas work

A West Midlands self-employed plumber has been jailed after carrying out further illegal and unsafe gas work.

During 2020 and 2021, Daniel Kelly Mountain, installed and worked on gas boilers and performed gas work when he was not registered as an individual with the Gas Safe Register. He also falsely advertised himself as being Gas Safe Registered. By law all gas businesses and individuals who perform gas work must be on the Gas Safe Register.

Official Gas Safe Register inspectors who checked on the work carried out by Mr Mountain found it to be unsafe, left in a condition of being ‘immediately dangerous’ or ‘at risk’. This placed the occupiers at risk to their safety.

A previous investigation by the Health and Safety Executive (HSE) in 2016 resulted in Mr Mountain being warned not to carry out any gas work until he was registered with Gas Safe Register. He was issued with a Prohibition Notice preventing him from carrying out further gas work until he was competent to do so and had become registered with the Gas Safe Register. However, Mr Mountain breached the Prohibition Notice and performed unsafe and unlawful gas work at a number of domestic properties across the West Midlands.

HSE guidance can be found at: Gas – HSE and details on the Gas Safe Register is widely available.

At Wolverhampton Crown Court on 6 October, Mr Mountain formerly of Wellington Court, Bilston, Wolverhampton, pleaded guilty to one breach of the Gas Safety (Installation and Use) Regulations 1998 Regulation 3(7), two breaches of section 3 of the Health and Safety at Work etc Act 1974, and one breach of section 22 of the Health and Safety at Work etc Act 1974. He received a 12-month custodial sentence.

Speaking after the hearing, HSE inspector Marie-Louise Riley-Roberts said: “Mr Mountain knew that he was not registered to undertake gas work, but still put the occupiers at risk by carrying out the work.

“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.

“A gas boiler must be properly commissioned by a competent registered gas engineer before being left operating otherwise you cannot be sure that it is working safely. Please let this be a warning to other rogue gas fitters.”
