Introduction

If you own or operate a commercial espresso machine in the UK, there is a legal requirement you may not be aware of: the Pressure Systems Safety Regulations 2000, commonly known as PSSR. These regulations govern the safe use of pressurised equipment, and your espresso machine's steam boiler falls squarely within their scope.

Many café owners, restaurant managers, and office facilities teams are unaware that their coffee equipment requires a formal inspection under PSSR. Ignoring these obligations can lead to serious safety risks, insurance complications, and even criminal prosecution.

In this guide, we explain exactly what PSSR is, which machines are affected, what the inspection involves, and how Espresso Repair can help you stay fully compliant.

What Are the Pressure Systems Safety Regulations 2000?

The Pressure Systems Safety Regulations 2000 (PSSR) are UK legislation enforced by the Health and Safety Executive (HSE). They apply to any system containing a relevant fluid (steam, compressed gas, or pressurised hot water) where there is a risk of danger from the stored energy if the system fails.

The regulations were introduced to prevent serious injury from the uncontrolled release of stored energy in pressure systems. They place duties on designers, manufacturers, importers, suppliers, owners, and users of pressure systems.

For coffee businesses, the key requirement is that any commercial espresso machine with a steam boiler operating above 0.5 bar must have a Written Scheme of Examination and undergo periodic inspections by a competent person.

Which Coffee Machines Are Affected?

Not every coffee machine falls under PSSR. The regulations specifically apply to machines with pressurised steam vessels, which includes the vast majority of traditional commercial espresso machines. Here is a breakdown:

If you are unsure whether your machine requires a PSSR inspection, contact Espresso Repair and we can advise based on your specific equipment.

What Is a Written Scheme of Examination?

Under Regulation 8 of PSSR, the user of a pressure system must not operate it unless a Written Scheme of Examination (WSE) has been drawn up by a competent person. This document outlines:

• The parts of the system to be examined
• The nature of each examination (visual, functional, or NDT)
• The maximum interval between examinations
• Any preparatory work required before each examination
• The measures needed to ensure the examination can be carried out safely

The WSE must be prepared before the system is first used, and it must be reviewed and updated as necessary. Espresso Repair provides a complete Written Scheme of Examination as part of our managed service plans, ensuring your documentation is always current and compliant.

What Does a PSSR Inspection Involve?

A PSSR examination is carried out by a competent person, typically an engineer with specific training and experience in pressure systems. During the inspection, the competent person will:

1. Visual inspection – Check the external condition of the boiler, pipework, and safety valves for signs of corrosion, damage, or leakage.
2. Safety device checks – Test the operation of pressure relief valves, safety cut-outs, and pressure gauges to ensure they function correctly.
3. Internal examination – Where possible, inspect the internal condition of the boiler for limescale build-up, corrosion, or material degradation.
4. Operational checks – Verify that the machine operates within its designed pressure and temperature parameters.
5. Documentation review – Confirm the Written Scheme is in place and that previous recommendations have been actioned.

Following the inspection, a formal report is issued. This report must be retained and made available for inspection by the HSE if requested. Espresso Repair provides a comprehensive report booklet with every PSSR examination.

How Often Is a PSSR Inspection Required?

The frequency of PSSR examinations is determined by the competent person who draws up the Written Scheme of Examination. For most commercial espresso machines, this is typically every 12 to 14 months, though it can vary depending on:

• The age and condition of the machine
• The quality of the water supply (hard water areas may require more frequent checks)
• The volume of use
• Previous inspection findings

It is important to note that the examination must take place before the date specified in the Written Scheme. Operating a pressure system beyond its examination date is a breach of the regulations.

What Happens If You Don't Comply?

Non-compliance with PSSR is a criminal offence under the Health and Safety at Work Act 1974. The consequences can be severe:

• Prosecution – The HSE can prosecute business owners who fail to maintain a Written Scheme or carry out required examinations.
• Fines – Unlimited fines can be imposed for breaches of health and safety legislation.
• Insurance implications – Many business insurance policies require PSSR compliance. An incident involving an uninspected pressure system could void your cover.
• Enforcement notices – The HSE can issue improvement or prohibition notices, potentially shutting down your equipment until compliance is achieved.
• Personal liability – Directors and managers can be held personally liable for health and safety failings.

Beyond legal risk, an uninspected boiler is a genuine safety hazard. Boiler failures, while rare, can cause serious injury from scalding steam or hot water.
