UK lost comms question to ATC

[Mr Falcon]

I'm a pilot and also teach Groundschool and in the Sim ( Corporate )

We carry a laminated Jeppesen lost comms page in our cockpits but it's complicated and the majority of crews would not know what to do.

Example : If we took off from a London airport and had a comms failure on a step climb SID would you deem it acceptable to SQ 7600 and route to nearest VOR / NDB , join published holding pattern while crew try and contact ATC , Ops, handling agent by Sat phone ?

Thanks in advance for any guidance, comments.
