Gas Safety

Every year people die from carbon monoxide poisoning caused by gas appliances and flues that have not been properly installed or maintained.

  • You can't see, taste or smell carbon monoxide.
  • It can kill without warning in just a matter of hours.

The early symptoms of carbon monoxide poisoning include:

  • Tiredness
  • Drowsiness
  • Headache
  • Pains in the chest
  • Stomach pains

You are at risk of carbon monoxide poisoning if:

  • Your appliance was poorly installed
  • Your appliance is not working properly
  • Your appliance has not been checked for safety or maintained regularly
  • There is not enough fresh air in the room
  • Your chimney or flue gets blocked up and/or
  • You allow unqualified people to install or maintain your appliance
  • The Gas Safety (Installation and Use) Regulations place duties on gas consumers, installers, suppliers and landlords.

Qualification and Supervision

Any person who carries out work on gas fittings and equipment must be competent and approved by the Health and Safety Executive (HSE).

As from 1st April 2009 the Gas Safe Register will replace CORGI Gas registration in Great Britain.

In practical terms the Gas Safe Register is the only organisation that will be recognised by HSE. Engineers must be Gas Safe Registered and hold the appropriate accreditation.

Those who employ any person to work on gas fittings and equipment have a duty to ensure they are competent.

Duties of Employers and Self-Employed Persons

Employers and self-employed persons have a duty to ensure that any gas appliance, pipework or flue installed in a workplace under his/her control is maintained in a safe condition.

It is recommended that the any gas appliance, pipework or flue is checked for safety at recommended intervals of not more than 12 months.

While there is no requirement to maintain written records of such maintenance, it is recommended in order to prove that maintenance has been undertaken.

Duties on Landlords

The two main duties imposed on landlords are:

  • Annual safety checks on gas appliances and flues
  • The provision of ongoing maintenance and remedial work
