EEMUA 251 has been produced to help Users, Competent Persons and Owners of pressure equipment achieve their legal requirements before pressure equipment is put into service in the United Kingdom.
The document has been developed by the Pressure Equipment Consultation Forum (PECF), Safety Assessment Federation (SAFed) and the Engineering Equipment and Materials Users Association (EEMUA) in consultation with LRQA and other stakeholders within the pressure equipment industry. It has been prepared using technical advice provided by the Health and Safety Executive (HSE).
Within this document are references to UK Legislation, GB Regulations and variations of the two. EEMUA 251 was published in 2025; at the time of publication the UK had legislated to continue recognition of CE marked equipment. The relationships of UK Legislation, GB Legislation and CE marking will likely change as technical and administrative divergence commences. The reader is encouraged to confirm the in-force legislation. In producing this document, the authors noted that many of the roles and responsibilities referenced overlap; caution should therefore be exercised when only reading a single or selected set of guidelines.
EEMUA 251 is a companion document to others in the UK PEDG/EEMUA series, namely: EEMUA 237, EEMUA 245 and EEMUA 248.
