Clear Channel has earmarked 100 six-sheets within 1km of outdoor ice rinks in Hyde Park, Canary Wharf, Somerset House, Natural History Museum, Tower of London, Kew Gardens, Alexandra Palace, Hampton Court and Trafalgar Square.
The offering also targets Christmas parks across the capital, such as Winter Wonderland in Hyde Park, which hosts Christmas markets, observation wheels, funfair rides and a Santa's grotto.
A spokesman for Clear Channel said planning resource YearAhead.co.uk predicts more than one million people are expected to go to an outdoor ice-skating rink in London this winter.
