Pressure Systems Safety Regulations 2000 (PSSR)
If your business operates compressed air systems, steam boilers, pressure vessels, or other pressurised equipment, compliance with the Pressure Systems Safety Regulations 2000 (PSSR) is a legal requirement. These regulations are in place to protect people and property from the potential risks and dangers of pressure system failures.


What Is PSSR?
The Pressure Systems Safety Regulations 2000 (PSSR) apply to systems containing a gas or liquid under pressure that could be dangerous if released.
The regulations state that pressure systems must be:
- Properly designed, operated, and maintained
- Examined at appropriate intervals
- Covered by a Written Scheme of Examination before being used
Businesses who don’t comply with PSSR can potentially face prosecution, insurance validation issues, and increased risk of employee injury or property damage.
Why PSSR compliance is important
A well-maintained, compliant pressure system is important for safety and efficiency. All systems are subject to wear, corrosion, and fatigue over time, and, without regular inspection, these issues can lead to leaks, failures, and safety risks.
Improve the lifespan and performance of your system
Avoid fines, penalties, and liability issues by meeting statutory requirements
Prevent dangerous failures and protect your employees
Identify faults before they cause potentially expensive breakdowns and costly downtime

Our Written Scheme of Examination (WSE) service
A Written Scheme of Examination is compulsory under PSSR. It states which parts of the pressure system need to be examined, the required frequency of inspections, and safe operating limits. The WSE must be certified by a Competent Person before the system is used and kept up to date through regular inspections.
At Airia, our WSE service includes:
- Ongoing support to ensure continued PSSR compliance through our service plans
- Assessment of your air compressor system
- A Written Scheme of Examination document
- Scheduling of examinations as required
- Reporting and certification
