Written Scheme of Examination

We support the creation and review of Written Schemes of Examination (WSE) for relevant pressure systems, ensuring the scope, examination requirements and inspection intervals are clearly defined and usable. WSE requirements sit within the UK Pressure Systems Safety Regulations (PSSR 2000).​

​​

What We Cover

Our WSE support focuses on the elements required to manage pressure systems safely and demonstrate compliance.

​

This typically includes:

• Identification of pressure systems and equipment within scope

• Clear definition of system boundaries and exclusions

• Examination requirements for vessels, pipework, and safety devices

• Practical inspection intervals based on system duty and risk

• Alignment with how systems are operated and maintained

​

How the Service Is Delivered

• Review of existing WSE documentation (where applicable)

• Support with defining scope, examination requirements, and intervals

• Practical, regulation-aligned approach focused on usability

​

The aim is a Written Scheme that can be confidently applied and maintained.

​

When WSE Support Is Needed

• Creating a new Written Scheme of Examination

• Reviewing or updating an existing WSE

• Following system modifications or extensions

• Preparing for regulatory or insurer review

​

What You Get

• A clear, compliant Written Scheme of Examination
