The party has published a mini-manifesto which will form part of their offer to voters.
Other ideas include cutting business rates for companies employing local people and exempting all new taxis from VAT.
Lawrence Webb, UKIP Mayor candidate, said: “UKIP is offering Londoners a fresh choice in the capital.
“Already much of the media are focusing on the two-horse race of Boris versus Ken, but it should be remembered that there are also places up for grabs on the London Assembly.
“A vote for UKIP in London would result in the party taking some of those places and holding those that run the capital to account.”
Other parties contesting the Assembly elections include Labour, the Conservatives, the Liberal Democrats and the Green party.
