The Public Campaign for the Arts (PCA) launched a petition in January after the authority set out its budget plans.
Nearly 5,000 people signed the petition and 1,800 people responded to the authority’s consultation. The PCA said celebrities Russell Brand, Mark Watson, Rachel Parris, Stephen K Amos and Alfie Moore backed their campaign.
Campaign director Jack Gamble said: “Windsor and Maidenhead’s arts centres were facing a 100% cut – today they’re facing a 17% increase in support from the council.
“Thank you to everybody who has been a part of our campaign, and to the council for listening to residents’ concerns.”
