Man handed suspended sentence after illegal boiler replacement risks carbon monoxide leak

A man has been given a suspended prison sentence after he carried out dangerous and illegal gas work on a property in Bournemouth which could have resulted in carbon monoxide poisoning.

David McCallum, 58, trading as McCallum Plumbing & Heating, attended a property in the Dorset town in February 2023. Part of the work carried out saw McCallum relocating a gas boiler and flue. However, following its installation, the homeowners noticed problems with it and had concerns over the standard of the work that had been done.

Part of the work carried out saw McCallum relocating a gas boiler and flue

They arranged for another gas engineer to check the installation. When they arrived, they carried out an inspection and deemed the boiler to be ‘immediately dangerous’. The gas boiler flue was not sealed or correctly positioned which meant that there was a risk of carbon monoxide leaking into the property.

The matter was reported to the Health and Safety Executive (HSE) and an investigation found that McCallum had no training in gas work and was not registered with the Gas Safe Register (GSR).

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.

McCallum knew he should have been registered with GSR to undertake the gas work, as he had previously been a director of a company that had been registered.

The gas boiler flue was not sealed or correctly positioned

The Gas Safety (Installation and Use) Regulations 1998 require those undertaking gas work to be Gas Safe registered and to hold the relevant qualifications to demonstrate their competence.

Members of the public are reminded that all gas work must be carried out by a Gas Safe registered engineer. Anyone can check whether an engineer is registered by visiting www.gassaferegister.co.uk or calling 0800 408 5500.

David McCallum of Balston Road, Parkstone, Poole, pleaded guilty to breaching Regulations 3(3), 27(1) and 27(5) of the Gas Safety (Installation and Use) Regulations 1998. He was sentenced to 10 months imprisonment, suspended for 12 months. He was also ordered to pay the homeowner compensation of £3,907 and £7,064 in costs at Bristol Magistrates’ Court on 13 February 2026.

In addition to this, McCallum was given a six-month electronic monitoring order restricting his movements over the weekends.

HSE inspector Simon Jones said: “David McCallum undertook gas work which he knew he was not registered to do – and his shoddy work replacing the boiler and flue meant there was an immediate danger of carbon monoxide leaking into the property.

“McCallum’s illegal gas work put the lives of innocent homeowners at risk for his own financial gain.

“All gas work must be conducted by registered Gas Safe engineers to ensure the highest standards are met to prevent injury and loss of life. Installers will be prosecuted if they carry out gas work without the proper qualifications.

“I advise all householders to check that anyone they allow to work on the gas supply is gas safe registered. This can be done in just seconds.”

The prosecution was brought by HSE enforcement lawyer, Julian White, HSE advocate, Rowena Goodwin and Paralegal Farhat Basir.

Father and son sentenced for carrying out illegal gas work

An unregistered gas installer and his father have been sentenced after carrying out illegal gas work at two houses in Cheshire.

An investigation by the Health and Safety Executive (HSE) found that Scott Lodge, 37, carried out new boiler installations at two addresses in Northwich in April 2022 and December 2022 – doing so while not being registered with Gas Safe Register.

On one of those occasions, his father Brian, 67, who is a registered gas engineer, signed off the work and commissioned the boiler on his son’s behalf. He did this without attending the property to check the boiler for safety.

Defects included a lack of support for the chimney and flue system

When one of the homeowners complained to the Gas Safe Register an inspection was carried out by a qualified engineer. That inspection identified defects resulting in the boiler being classed as at risk and a danger. This included a lack of support for the chimney and flue system, which carried the risk of carbon monoxide poisoning.

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. Anyone can check whether an engineer is registered by visiting www.gassaferegister.co.uk or calling 0800 408 5500.

Scott Lodge, of Adlington Drive, Northwich, pleaded guilty to breaching Regulation 3(3) of the Gas Safety (Installation and Use) Regulations 1998. He was given a 12-month community order and complete 200 hours of unpaid work. He was also told to pay £2,500 in costs at Chester Magistrates’ Court on 22 December 2025. He must also pay £1,460 to one of the affected homeowners, which covered the cost of the work.

Brian Lodge, of Merriman Avenue, Knutsford, pleaded guilty to breaching section 3(2) of the Health and Safety at Work etc. Act 1974. He was given the same sentence as his son and ordered to pay the same in costs at the same hearing.

Following the hearing HSE Inspector, Ian Betley, said: “This was a deliberate breach of gas safety legislation by Scott Lodge who undertook gas work which he knew he was not registered to do.

“His failures could have led to catastrophic and tragic consequences for the homeowners. To make matters worse, Brian Lodge knowingly signed off the work as safe, despite not examining or testing it.

“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. Furthermore, registered gas engineers must not circumvent the legislative requirements by signing off unregistered work as their own.”

This prosecution was brought by HSE enforcement lawyers, Sam Crockett and Karen Park, and paralegal officer, Stephen Grabe.

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.”
