PSSR examination and written scheme in Preston

Written Schemes of Examination and certified pressure system examinations by an independent competent person

A pressure switch and a safety valve look like teammates and are not: one controls, the other protects, and a system whose protection is really just its control has none when the control fails. Around Preston's plant rooms and workshops, the Pressure Systems Safety Regulations 2000 insist on the difference.

PSSR examination and certification for Preston businesses

Pressure systems across the city run from compressed air installations, their controls and protective devices, through process plant to the receivers and workshop systems of the estates.

The control-versus-protection confusion fails on the worst day: cut-out switches trusted as if they were relief, safety valves isolated, seized or set wrong because the switch always got there first, protection sized for a system that has since grown, and nobody able to say which device is doing which job. Our examinations sort the roles honestly, safety valves proven to lift at set pressure, controls verified as controls, the Written Scheme naming each device's actual duty, and 28 day reports leaving no doubt about what protects what.

PSSR FAQs

PSSR examination, written schemes and certification: common questions

Do you carry out PSSR examinations in Preston?
Yes. Our engineer surveyors cover Preston and the sites around it, examining control sorted from protection. Call us to arrange a visit.
How soon can you examine a pressure system in Preston?
We keep availability across Lancashire, so a Preston visit is usually within a couple of working days, sooner when a system is waiting on its examination before use. Call 0330 043 8191 to book.
What is a Written Scheme of Examination, and do I need one?
It is the legal document at the heart of PSSR: a scheme drawn up and certified by a competent person that sets out which parts of a pressure system are examined, how, and how often. A system within scope must not be operated without one, and the HSE sets the minimum content in its pressure systems guidance.
Is PSSR a legal requirement, and what does it cover?
Yes. PSSR 2000 applies to systems holding steam at any pressure, or other fluids above roughly 250 bar litres, so steam boilers, air receivers, compressors, autoclaves and many process vessels are caught. The duty sits with the user of an installed system or the owner of a mobile one.
How often must a pressure system be examined?
There is no single interval fixed in law. The competent person sets the frequency for each item in the Written Scheme of Examination, judged on the system, its contents and its duty, with many items examined around every 12 months. The examination report is issued within 28 days and carries the next due date.
Who can be the competent person for PSSR?
Someone with the right combination of training, skill, experience and knowledge for the system in question, and independent enough to judge it fairly. The competent person both draws up or certifies the scheme and carries out the examinations it sets.
Does servicing the equipment count as a PSSR examination?
No. A PSSR examination is a formal statutory examination of the system's integrity against its written scheme, and it is separate from routine maintenance. Maintenance keeps a system running; it does not satisfy the legal duty to examine it.
What happens if the examination finds a defect?
The report records the defect, any limit on continued use and the date the next examination is due. Where the competent person finds a risk of imminent danger, the system must be taken out of use at once and the enforcing authority notified, so a problem is acted on rather than filed.
