P&ID drawings for gas and compressed air systems
Clear, accurate drawings of your gas system, so engineers, auditors and insurers can see exactly how it is laid out and where to isolate it.
What is a P&ID?
A piping and instrumentation diagram (P&ID) is a detailed drawing of your gas or compressed air system. It shows all pipe routes, valves, instruments, safety devices, control points, pressure zones and flow direction.
Why you need one
- Safety: every control point, valve and relief device is visible, which supports emergency planning and hazard identification
- Compliance: P&IDs support your Written Scheme of Examination and help show PSSR compliance
- Maintenance: engineers know exactly where and how to isolate each part of the system
- Upgrades: expansions and changes are easier and cheaper to plan
What we supply

P&ID Drawings: common questions
Do I legally need a P&ID?
PSSR does not name P&IDs specifically, but you must be able to identify every part covered by your written scheme. A P&ID is the clearest way to do that, and many insurers and auditors expect one.
Can you draw a P&ID for an existing system?
Yes. We survey the installation as it is today and draw it accurately, including any changes made over the years.
What format will I get?
PDF for everyday use, and CAD files so the drawings can be updated in future.
How is the work priced?
We give you a fixed quote based on how much equipment you have and the size of your site, so you know the cost before we start.
Do you provide RAMS and follow our site rules?
Yes. We provide risk assessments and method statements (RAMS) before work starts, and we follow your site's induction, permit-to-work and safety rules.
