The first £1bn in extra funding for social care in England will be available "right now", ITV News Social Affairs Editor Penny Marshall has said.
Chancellor Philip Hammond's big announcement in Wednesday's Spring Budget was an additional £2bn over three years to help ease the pressure on social care.
The money, with £1 billion promised in 2017/18, follows intense pressure from MPs and councils, but falls short of the levels of funding demanded by some campaigners.
Penny Marshall said: "I've been able to establish that the £1bn is available right now, so for those struggling councils they will be able to commission care packages.
"It's going to hold them over until the better care fund comes into place, so there is some light, temporary light, at the end of the tunnel."
The increase - which will add an average of £240 to the bills of self-employed workers - was described as a "modest but welcome change".
The Chancellor has defended plans for a 2% rise in National Insurance for self-employed workers - arguing it makes the system more "fair".
Chancellor Philip Hammond shed his strait-laced image and showed a more humorous side as he packed his first Budget with jokes.
