About P4 Limited

For more than 30 years, P4 Limited has designed and manufactured self-testing emergency lighting and signage. All our products are rigorously tested and fully compliant with current regulations.

They provide valuable illumination of escape routes and direct people out of premises in the event of a failure of the normal lighting.

We work with customers in education, general healthcare, mental healthcare, transportation, sports, leisure and retail, delivering and supporting world class emergency lighting systems; excelling in building long term partnerships with facilities and estates management teams.

As the UK’s largest independent self-testing emergency lighting specialists, our growth has required us to move to our current premises, a purpose-built headquarters, factory and office complex.

Our success and continued growth is based on continuous innovation, exceptional service and a total focus on providing the most cost effective, reliable and compliant emergency lighting solution for all premises.
At the heart of P4’s commitment to excellence is the desire to ensure the safety of anyone facing hazardous situations and needing the benefit of the very best emergency lighting.
