If you are there by 06:50 then you should be OK, any later then ask the front person from LCY security to assist you through. My very worse security time in LCY - which was off the scale and never repeated - was soon after the then new hall was opened and it took me 15 minutes. Flights were held back a bit to help travellers. More recently it's essentially 5 minutes or less to get through.

Obviously do what you can to minimise a secondary, so keep liquids, electronics, wires out of the main bag. They use a similar system to T5 and LGW, so multi-user bays with very large trays.
