We can confirm that the design of Crossrail electrical installations are, and have been, developed to comply with the Statutory Instruments Regulatory Reform (Fire Safety) Order 2005 Guidance Note 3: Fire safety on sub-surface railway stations.

In compliance with this order we have used the guidance where necessary included within BS8519.

1. Have Crossrail electrical installations been designed, installed, tested, inspected and certificated to the requirements of BS7671?
2. If so, what version/s of BS7671 are the installations compliant with?
3. If the answer is yes to the above, are there any intended departures from the regulations on any of the electrical installations and if so, are the required risk assessments in place assuring that the resulting degree of safety of the installations is not less than that obtained by compliance with the Regulations?

We can confirm that Crossrail has been designed in compliance with the 17th edition of the IET Wiring Regulations BS7671. Not all locations have been completed but those that have are compliant for the installation and testing with17th edition of the IET Wiring Regulations BS7671 excluding departures. The only departure listed so far is with the UPS system.
