The summer campaign , titled Why Not, will run from June 18 to July 15, and the winter push from Nov 19 to Dec 16.
Poster ads will be shown at landmark sites and tube stations in London and on screens at Manchester, Leeds and Edinburgh railway stations and Birmingham International Airport.
Lanson will also be sponsoring five events this summer. As well as continuing its association with Wimbledon and the Royal Albert Hall, the brand has also signed up to be the official Champagne supplier to the Tour de France, Newmarket Racecourse and the Edinburgh Military Tattoo.
Paul Beavis, UK marketing director of Champagne Lanson, said: "We share the same values of excellence and distinction and, ultimately, we are all dedicated to bringing immense enjoyment to all."
