Summary of the Pressure Equipment Regulations 1999: Ensuring Safe Operation of Pressure Equipment

The Pressure Equipment Regulations 1999, enacted in the United Kingdom, provide a framework for ensuring the safe design, manufacture, installation, and use of pressure equipment. These regulations aim to prevent accidents, protect the health and safety of workers and the public, and promote compliance with essential safety requirements. This summary provides an overview of the key provisions and objectives outlined in the Pressure Equipment Regulations 1999.


The Pressure Equipment Regulations 1999 apply to a wide range of pressure equipment used in various industries, including boilers, pressure vessels, heat exchangers, and pipelines. The regulations cover both new and existing equipment and apply to manufacturers, importers, suppliers, and users of pressure equipment.

Safety Requirements:

The regulations establish essential safety requirements that pressure equipment must meet. These requirements include specifications for design, construction, and testing to ensure the equipment's integrity and ability to withstand pressure. Compliance with recognized standards, such as the European harmonized standards or approved codes of practice, is typically used to demonstrate conformity with these safety requirements.

Certification and Marking:

Pressure equipment falling under the scope of the regulations must undergo a conformity assessment procedure to ensure its compliance with the applicable safety requirements. This assessment may involve examination, inspection, and testing by a notified body or a competent authority. Once deemed compliant, pressure equipment receives a CE mark and a declaration of conformity, indicating that it meets the necessary safety standards.

Obligations of Manufacturers and Suppliers:

Manufacturers and suppliers of pressure equipment have several obligations under the regulations. They must ensure that equipment is designed and manufactured in accordance with the applicable safety requirements, carry out conformity assessments, and provide technical documentation demonstrating compliance. Manufacturers must also affix the CE mark and provide user instructions and safety information with the equipment.

Installation and Use:

The Pressure Equipment Regulations also address the installation and use of pressure equipment. Installers must ensure that equipment is properly installed, taking into account factors such as location, support, and connection to other systems. Users of pressure equipment must adhere to specified operational conditions, maintenance requirements, and periodic examination and testing to ensure ongoing safety and integrity.

Notified Bodies and Competent Authorities:

The regulations establish the role of notified bodies and competent authorities in the conformity assessment process. Notified bodies are independent organizations designated by member states to carry out conformity assessments. Competent authorities are responsible for enforcing compliance with the regulations and may undertake inspections, investigations, and enforcement actions when necessary.

Enforcement and Penalties:

Enforcement of the Pressure Equipment Regulations is carried out by competent authorities. Failure to comply with the regulations can result in enforcement actions, including prohibition notices, improvement notices, and prosecutions. Non-compliance may lead to penalties, fines, or restrictions on the use or sale of pressure equipment.

The Pressure Equipment Regulations 1999 provide essential guidelines and requirements for ensuring the safe operation of pressure equipment. By setting safety requirements, establishing conformity assessment procedures, and outlining the obligations of manufacturers, importers, suppliers, and users, these regulations contribute to minimizing the risks associated with pressure equipment and protecting the health and safety of workers and the public. Compliance with the Pressure Equipment Regulations is crucial to maintain safe working environments and prevent accidents related to pressure equipment failure.
