The German was slapped with the time penalty after the race stewards ruled that Mercedes had breached regulations regarding banned messaged when Rosberg's race engineer assisted him in the wake of a gearbox problem.
Thanks in part to Nico Rosberg's controversial radio-call penalty, the British driver closed to within a single point of the championship lead by winning at Silverstone.
Apparently they gave him a few too many instructions, for the stewards would later deem that the team was in violation of the radio communication regulations.
Defending champion Lewis Hamilton reeled off his fourth win in five races Sunday to storm to victory in the British Grand Prix and trail Nico Rosberg by one point. When the safety vehicle finally pitted at the end of lap five, Hamilton established a lead of almost four seconds in just one lap over Rosberg.
The Briton led from a safety vehicle start for his fourth win of the season and the 47th of his career as he equalled Nigel Mansell's British record of four F1 wins, while Australia's Daniel Ricciardo narrowly missed out on a podium finish.
Behind the top three of Hamilton, Rosberg and Verstappen, Ricciardo made it a fourth for Red Bull, and Kimi Raikkonen somehow managed to end up in fifth after a race that saw him up and down.
At the time, Rosberg's auto had developed a gearbox problem and he was being advised on how to circumnavigate it - which Mercedes felt was legal as the rules allow such communication if a vehicle has a potentially terminal problem.
It meant it had to be started with a safety auto.
Mercedes-Benz plans to appeal against this decision and penalty. Verstappen with a win, a second and a third is on 98.
He received instructions from his team on how to work through the problem, but teams giving advise over the radio is against F1 rules.
"But I would definitely say through that rough patch I was going through in terms of reliability, it is hard to handle when you want to win the world championship as much as I do".
Sixth and seventh spots went to Perez and Hulkenberg in the Force Indias, eighth to Sainz in the Toro Rosso, ninth to Vettel in the Ferrari and tenth to Kvyat in the second Toro Rosso.
