The former UKIP leader said he had already registered the name ahead of the possible change and said the new party would “have to campaign to change politics for good”.
Asked what would happen to the Brexit Party if the UK leaves the EU on January 31, he told Sky News’s Sophy Ridge On Sunday: “It’ll have to reform into the ‘reform party’, it’ll have to campaign to change politics for good, get rid of the House of Lords, change the voting system.
“So much to do and again you’ll see on Thursday a turnout much lower than the pundits expect because people have lost faith in politics.”
Asked if the Reform Party was a possible new name, he added: “Absolutely, I’ve registered it already.”
Mr Farage claimed the Brexit Party stood a good chance of winning a “handful” of seats in Thursday’s General Election.

Asked how many seats his party could win, Mr Farage said: “Well I think there’s a handful in which we’ve got a seriously good chance of winning and I think we will get some in, I genuinely do.”
Mr Farage has had a tough week after four MEPs walked out of the fledgling outfit on Thursday to campaign for the PM’s Brexit deal.
Annunziata Rees-Mogg, sister of Commons Leader Jacob Rees-Mogg, along with Lance Forman and Lucy Harris all resigned the whip, while John Longworth, who was sacked on Wednesday for having “repeatedly undermined” Mr Farage’s election strategy, confirmed he was formally leaving the party.
Mr Farage said: “I haven’t fallen out with anybody. I haven’t moved….Of course I want Brexit done, but I want the right Brexit done.”
Mr Farage cast doubt on Mr Johnson’s Brexit deal, but added there was “still time for it to be amended”.
He warned: “We will be back in crisis by June unless this Withdrawal Agreement is amended and that is the fight I’ve got and I want just to get a bridgehead of Brexit Party MPs in Parliament to hold Boris Johnson to account, because otherwise we’re going to see Brexit sold out.”
