Plumber fined for sub-standard boiler installation

13 April 2015

A plumber from Malswick has been fined £250 after installed an oil fired boiler at a property that had the potential to cause death from CO poisoning. 

Nigel Grinnell, 48, from The Willows, Malswick, Gloucestershire pleaded guilty to breaching Section 3 (2) of the Health and Safety at Work etc Act after  Cheltenham Magistrates’ heard the boiler was installed in a compartment with inadequate ventilation and an unsuitable material, flue liner, linking the boiler into the chimney. 

No problems were noticed for around six months until the householder came home to find the house full of smoke and fumes. The flexible flue liner had dipped to form a moisture trap. This had become full of water which had fully or partially blocked the flue. These conditions led to incomplete combustion and the spillage of products of combustion including carbon monoxide. 

Notes to editors: 

  1. The Health and Safety Executive is Britain’s national regulator for workplace health and safety. It aims to reduce work-related death, injury and ill health. It does so through research, information and advice, promoting training, new or revised regulations and codes of practice, and working with local authority partners by inspection, investigation and enforcement.   
  2. Section 3(2) of the Health and Safety at Work etc Act places general duties on everyone ‘at work’ including the self-employed. It states ‘It shall be the duty of every self-employed person to conduct his undertaking in such a way as to ensure, so far as is reasonably practicable, that he and other persons (not being his employees) who may be affected thereby are not thereby exposed to risks to their health and safety’.
