Garage Air Compressor and Pressure System Requirements
A practical guide to garage air compressor and pressure-system requirements, including Written Schemes of Examination, air receivers, inspections and records.
Why this requirement may appear
Compressed-air systems hold stored energy. If an air receiver fails, the release of that energy can cause serious injury or damage. The Pressure Systems Safety Regulations 2000 (PSSR) are intended to prevent such failures by requiring most qualifying pressure systems to have a Written Scheme of Examination and to be examined in line with it.
When you create or review a garage health and safety policy template, include your local arrangements for compressor safety, responsibilities, maintenance and record keeping. The policy is an overview of your arrangements; it does not replace the Written Scheme of Examination for a qualifying system.
What to do
Check whether your compressed-air system is a qualifying pressure system under PSSR (most garage air receivers with a stored volume and pressure above the thresholds qualify). For qualifying systems, keep a Written Scheme of Examination prepared by a competent person.
A Written Scheme of Examination identifies the relevant components — typically the air receiver and protective devices — and specifies the nature and frequency of the examinations needed. The examination schedule, including the next due date, must therefore be taken from the Written Scheme, not from a generic annual or 24-month rule.
Your garage health and safety policy should record who is responsible for checking the scheme and report are current, how compressor maintenance is arranged, and where the equipment record is held. Keep routine maintenance separate from the statutory examination: servicing the compressor, draining the receiver and checking safety valves is day-to-day maintenance; it is not the same as the competent-person examination required by the scheme.
Evidence to retain
Keep the Written Scheme of Examination, the most recent examination report from the competent person, the air receiver details, the competent person's details, the last examination date, the next examination date specified by the scheme, maintenance records, and any defects with evidence of remedial work.
Keep this evidence organised
Motor Trade Ready can help you record the relevant date and keep supporting evidence alongside the rest of your garage compliance records.
Typical review timing
The next examination date is set by the Written Scheme of Examination for each system, based on the competent person's assessment — not by a universal interval. Use the date on the scheme.
Practical next steps
Add compressor and pressure-system arrangements to your garage health and safety policy, tailored to the equipment at your site. Keep an air-system record showing the air receiver, the scheme, the last and next examination dates, the competent person, and any defects and remedial work. Set reminders so the next examination date is not missed. Motor Trade Ready can hold these dates, the documents and the actions in one place alongside your other compliance records.
When specialist help may be appropriate
The Written Scheme must be drawn up by a competent person — usually an inspection body or an insurer's engineering service. If a garage cannot locate a scheme for an existing air receiver, or has added a receiver, a competent person should be engaged to prepare or review the scheme before the system is used.

Frequently asked questions
What should a garage health and safety policy say about compressors?
A garage health and safety policy should identify compressed-air systems as a stored-energy risk, name the person responsible for the equipment record, require maintenance and drainage arrangements, and require the Written Scheme of Examination and competent-person report to be kept current. The policy does not replace the Written Scheme of Examination.
Can I use a garage health and safety policy template for compressor safety?
A policy template can help document the garage's general arrangements for compressor safety, responsibilities and record keeping. It must be tailored to the equipment and working arrangements at the site, and it cannot substitute for the Written Scheme of Examination required for a qualifying pressure system.
Why do compressed-air systems require attention?
An air receiver stores compressed air under pressure, so it holds significant stored energy. If it fails, that energy can be released suddenly and cause serious injury or damage. PSSR exists to reduce that risk.
When does PSSR apply to a garage?
PSSR applies to most garage compressed-air systems that include a pressure vessel such as an air receiver above the regulation's size and pressure thresholds. If in doubt, ask a competent person whether your system qualifies.
What is a Written Scheme of Examination?
It is a document, prepared by a competent person, that identifies the pressure-system parts to be examined and specifies the nature and frequency of those examinations. For qualifying systems it is required under PSSR.
What is the difference between an air receiver and a compressor?
The compressor generates the compressed air; the air receiver stores it. The Written Scheme and statutory examination usually focus on the receiver and its protective devices, while the compressor itself is maintained.
Who can prepare or certify the scheme?
A competent person, typically an inspection body or an insurer's engineering service with the right knowledge of pressure systems, prepares or certifies the scheme.
How often should examinations happen?
As often as the Written Scheme specifies for that system. There is no universal annual or 24-month interval for every air receiver; use the date set by the scheme.
What is the difference between maintenance and statutory examination?
Maintenance is routine servicing such as draining the receiver and checking valves. A statutory examination is the competent-person assessment required by the Written Scheme. They are separate and one does not substitute for the other.
What documents should be kept for a pressure system?
Keep the Written Scheme, the most recent examination report, air receiver details, competent-person details, last and next examination dates, maintenance records, and evidence that any defects have been addressed.
What should a garage health and safety policy template include for an air compressor?
Include the compressor and air receiver as a site-specific risk, the responsible person, the location of the Written Scheme of Examination and reports, maintenance and drainage arrangements, defect reporting, and how the next examination date is monitored. Adapt the policy to the equipment and work carried out at your garage.
Does a garage health and safety policy template replace a Written Scheme of Examination?
No. A health and safety policy records your general management arrangements. A qualifying pressure system needs its own Written Scheme of Examination from a competent person, with examinations completed in line with that scheme.
