At that point they're going to fly so he'd remove his hand from the throttles. The F/O would keep his hands to his self. Most airlines have the non flying pilot make the "positive rate" call and the flying pilot replies "gear up." Departure out of LHR uses "London Control" as their callsign and a current chart for the WOBUN 3F shows 119.77 as the freq. Tens can use 5, 15 or 22 degrees of flaps for takeoff, going LHR to SFO I'd guess they'd use 5 so the pilot flying would call "flaps up" and the non-flying pilot would repeat the command and move the flap lever. London has radar so they know where you are and what you're doing. The whole reason for have departures is so the controller doesn't have to tell you to turn at the London 7 DME to join the Midhurst 357 radial. The check in might go something like:

Michael switched frequency, enabling Robert to speak to their third ground-based communication team.
‘Control, good evening,’ Robert said warmly, ‘Cali Two Zero Seven, climbing through eight hundred feet to four thousand feet, on the WOBUN Three Foxtrot departure.’
Another voice greeted the cockpit via the radio: ‘Cali Two Zero Seven, Departure, good evening. Cross 14 DME from London at flight level six zero.’
‘Roger, Cali Two Zero Seven, Cross the London 14 DME fix at flight level six zero.’
