Pressure Equipment (Safety) Regulations 2016

The Pressure Equipment (Safety) Regulations 2016 came into force on the 8 December 2016 and have subsequently been amended by Schedule 24 of The Product Safety and Metrology (Amendment) (EU Exit) Regulations 2020.

These Regulations cover pressure equipment and assemblies with a maximum allowable pressure PS above 0.5 bar.

HSE is responsible for enforcing the PE(S)R in the case of pressure equipment and assemblies being used in the workplace, and local authorities would be responsible where the equipment or assemblies are for private use or consumption.

The regulations apply to design, manufacture and conformity assessment of pressure equipment and assemblies of pressure equipment with a maximum allowable pressure above 0.5 bar.

Conformity assessment is carried out by Conformity Assessment Bodies (also known as Approved Bodies). There is a list of Conformity Assessment Bodies accredited under PE(S)R on the GOV.UK website.

The regulations do not apply to:


Schedule 2 of PE(S)R details the essential safety requirements (ESR) that qualifying vessels must satisfy. Additionally, there are details of how the different products are classified, the technical requirements that must be satisfied, and the conformity assessment procedures that must be followed.

The Office for Product Safety & Standards have produced guidance on the Pressure Equipment Safety Regulations 2016 on GOV.UK.

Note: The Regulations do not apply to the assembly of pressure equipment on the site and under the responsibility of the user, as in the case of industrial installations. In such cases, the Pressure Systems Safety Regulations 2000, which contain 'in use' provisions, will apply.
