Policies

• Codes & Standards: Pressure relief valves in the United Kingdom are governed by the Pressure Equipment (Safety) Regulations 2016, which implement the EU Pressure Equipment Directive (PED) into UK law. British Standards include BS EN ISO 4126 for pressure relief valve performance and BS 6759 for safety valve specifications. These standards set design, testing, inspection, and certification requirements for pressure relief valves used across oil and gas, chemical processing, power generation, and industrial sectors. Compliance with UK pressure equipment regulations is a mandatory purchasing requirement. • Environmental Regulations: Environmental oversight includes Environment Agency regulations for industrial emissions, pollution prevention, and environmental permitting. The UK's Net Zero strategy and carbon reduction commitments drive adoption of low-emission technologies. Offshore environmental regulations under the Offshore Petroleum Regulator for Environment and Decommissioning (OPRED) affect pressure relief valve requirements in North Sea operations. Emission control requirements affect valve design and operation, particularly in chemical plants and offshore facilities. • Government Incentives & Industrial Programs: The UK government provides incentives for industrial decarburization, hydrogen infrastructure development, carbon capture utilization and storage (CCUS), and renewable energy expansion. Programs under the Industrial Decarburization Challenge and Net Zero Innovation Portfolio support new process facilities and energy transition projects. These initiatives influence pressure relief valve procurement by supporting new industrial facilities, hydrogen projects, and CCUS infrastructure. • Worker Safety & Process Safety Regulations: The Health and Safety Executive (HSE) governs workplace safety, including the Control of Major Accident Hazards (COMAH) regulations for facilities handling hazardous materials. Employers must implement mechanical integrity programs, regular inspection and testing of pressure relief valves, documentation, and employee training. HSE inspection requirements ensure proper valve maintenance and compliance with safety regulations. • Regional Regulatory Differences: Scotland hosts major North Sea oil and gas operations subject to offshore safety regulations and Scottish environmental requirements. North East England hosts chemical and process industries along Teesside subject to HSE and Environment Agency oversight. The Humber region hosts refining and chemical operations with specific environmental requirements. Regional differences in industrial concentration and regulatory enforcement influence valve selection and procurement practices.
