Common Questions About CP16

Do I need CP16 for altered pipework?

Yes, altered commercial gas pipework normally needs testing and purging before it is put into service.

Can appliances be connected before testing?

Need a Different Commercial Gas Record?

If your site includes boilers, water heaters, LPG, pipework changes or catering equipment, our engineer can confirm which commercial gas record applies before work begins.
