The Citizens Advice Bureau is worried it could lose its primary funding under proposed new laws to control local government spending.
Chief executive Kerry Dalton told a Parliamentary select committee the bill would restrict council spending to core functions such as roads, rubbish and infrastructure.
She says some councils are prepared to sign only a one-year contract to fund their local advice bureau because of the proposed legislation.
She wants the Citizens Advice Bureau, which is used by more than 500,000 people every year, to be included in the bill.
