Redbridge Council is considering the future of Wanstead Youth Centre, which it claims is in need of over £2.4m of refurbishments.
But campaigners have objected to the style of questioning used in the consultation – which runs until 13 March – and insist the Elmcroft Avenue venue is a vital resource in a good state of repair.
If the closure is progressed, groups that use the centre will need to find alternative premises by May.
An on-site public meeting will take place on 7 March from 7.30pm.
