Businesses in retail, hospitality and leisure will receive new grants to help them keep afloat until spring, Chancellor Rishi Sunak has said.
The grants will be worth up to £9,000 per property, the Treasury says.
The help is in addition to business rates relief and the extended furlough scheme which has been extended until the end of April.
Separately, £594m will be made available to affected firms outside these sectors, Mr Sunak said.
In total, the package of measures is worth £4.6bn.
