He told the BBC he was planning to meet more than 100 Reform candidates in the North West as part of his local election campaigning.
Farage admitted that he had mixed expectations of success in some parts of Greater Manchester.
Earlier this month, Labour’s Greater Manchester Mayor Andy Burnham claimed a vote for Reform UK in the local elections could threaten regeneration projects in Greater Manchester.
He urged voters to resist “taking out their frustrations” with national politics on “hard-working local councillors”.
But Reform said they offered “better stewardship of council taxpayers’ money”.
Farage told BBC North West: “There are parts of Greater Manchester that are very bad for us, but equally parts that are very good for us.
“I’m not going to pin it down but in Tameside perhaps, might be one that you’d favour for us.
“But I don’t want to overly raise expectations, but what I will say is the map of local government will look very different after 7 May across the North West.”
