A silver medal for Lockerbie's David Murdoch's all-Scottish rink and a bronze for Eve Muirhead's similarly Caledonian side contributed to GB matching its medal haul from Chamonix, 1924.
Joining the Scots at Heathrow were England's skeleton gold medallist Lizzy Yarnold and snowboard slopestyle bronze medallist Jenny Jones.
Murdoch had described Friday's defeat of his men's curling team to Canada as "like a kick in the teeth" but had recovered and was all smiles.
He is also considering coming back to compete at the next Winter games in four years in South Korea.
On Sunday, he had said: You go through a lot of emotions. I need to speak to a lot of people. I need to speak to Sport Scotland, UK Sport, my wife and the team, but certainly there is still an appetite to go on."
Meanwhile, Muirhead, 35, of Stirling, looked contented with her medal after missing out on glory at Turin in 2006 and Vancouver in 2010.
