Most permit systems have not changed in twenty years. Pen written, hard to read, slow to raise, slower to approve, lost in a drawer when someone asks for it and no record of who was working under what isolation. SES Safe Permit fixes that on any device, in minutes. Click through the live screens below.

Most projects have no arc flash awareness at all, and no documented register of who has been told. Everyone who walks past a switchroom needs to know what an arc flash is, where the boundary is and what the label means. SES delivers it in five minutes and records every pass.
A QR code at the site entrance, in the welfare cabin or on the switchroom door. Scan it with any phone camera. No app, no login.

Safe Energy Solutions was founded by Chris Greenwood, a 33 kV Senior Authorised Person with HV and LV switching and client side Energy Marshal experience on hyperscale data centre projects across the UK, Europe, the Middle East, Asia and APAC. Every SES document and every Safe Permit workflow comes from procedures that have been run on live sites, under real commissioning pressure.
SES uses decorated and experienced Energy Marshals and Senior Authorised Persons for its design and review process, many of them internal to SES. Nothing leaves SES without our experienced team and our thorough internal review process behind it.
