That sounds like a T4S to T4 change which would involve security.
You will have the option to disembark from the rear and take a bus to T4S from the LGW gate where you will be deposited into the departures area directly or if you feel like walking a bit between flights you can go through two separate passport controls, but no security and walk the terminal to the train back to T4S.
