Stay Compliant. Stay Protected.
Under UK law, all pressure systems — including compressed air — must have a Written Scheme of Examination (WSE) in place. At PCM Engineering, we help businesses meet these legal requirements with clear, compliant, and practical WSE documentation backed by our engineering expertise.
What is a Written Scheme of Examination?
A WSE is a legally required document under the Pressure Systems Safety Regulations (PSSR) 2000. It outlines:
- Which parts of your pressure system need examination
- How and when examinations should be carried out
- The safety measures required to protect your business and employees
Our WSE Service Includes:
- Full inspection of your compressed air system by qualified engineers
- Preparation of a compliant Written Scheme of Examination
- Clear reporting on system condition and risks
- Guidance on remedial actions if required

Ensuring Compliance: Written Scheme of Examination (WSE) Services by PCM AIRPOWER
PCM AIRPOWER specializes in providing expert Written Scheme of Examination (WSE) services for your compressed air systems, ensuring you meet the stringent requirements of UK safety legislation.
What is a Written Scheme of Examination?
A Written Scheme of Examination (WSE) is a detailed document that defines the scope, frequency, and methods for the thorough examination of your pressure equipment and its protective devices. It is a legal requirement under the Pressure Systems Safety Regulations 2000 (PSSR 2000) for most compressed air receivers and associated pressure vessels.
Why is a WSE Necessary?
Compliance with the PSSR 2000 is mandatory for system owners and users. These regulations are designed to prevent danger from the stored energy of compressed gases and fluids.
- Legal Compliance: Failure to have a current and valid WSE and adhere to its examination schedule is a breach of health and safety law.
- Safety Assurance: The scheme ensures that critical safety components, such as air receivers and safety relief valves, are regularly inspected by a competent person to prevent catastrophic failure.
- Insurance Requirements: Your commercial insurance policy will likely require proof of compliance with PSSR 2000, including up-to-date WSE documentation and examination certificates.
