HSE L56 ACOP – Safety in the installation and use of gas systems and appliances

This Approved Code of Practice and guidance gives practical advice on the Gas Safety (Installation and Use) Regulations. It is for anyone who may have a duty under the regulations, including those who install, service, maintain or repair gas appliances and other gas fittings.

This fourth edition has been refreshed and updated. It now includes guidance and ACOP on standards of training in safe gas installation.

Approved Code of Practice

This Code has been approved by the Health and Safety Executive, with the consent of the Secretary of State. It gives practical advice on how to comply with the law. If you follow the advice you will be doing enough to comply with the law in respect of those specific matters on which the Code gives advice. You may use alternative methods of those set out in the Code in order to comply with the law.

However, the Code has a special legal status. If you are prosecuted for breach of heath and safety law, and it is proved that you did not follow the relevant provisions of the Code, you will need to show that you have complied with the law in some other way or a Court will find you at fault.

This guidance is issued by the Health and Safety Executive. Following the guidance is not compulsory, unless specifically stated, and you are free to take other action. But if you do follow the guidance you will normally be doing enough to comply with the law. Health and Safety inspectors seek to secure compliance with the law and may refer to this guidance.
