Relatives of those killed in the London bombs are to receive payments of at least £10,000 through a special fund.
£2.8m has been made available in grants through the fund
Survivors left seriously injured could receive up to £15,000, while those unable to work for more than four weeks are to be offered up to £3,000.
The money will come from the London Bombings Relief Charitable Fund, which has raised almost £9m from the public.
Meanwhile, lawyers have warned hardship may be caused by delays in criminal injuries compensation payments.
The fund, administered by the Red Cross, is made up of donations from charities, firms and individuals.
Organisers said that as well as a £10,000 grant for relatives of those who died, there would be an additional payment for each dependent child.
These sums top up earlier grants from the fund, bringing the amount made available in grants so far to £2.8m.
John Stoker, the fund's chief executive, said: "These grants represent substantial help to the bereaved and the seriously injured on top of the sums the fund has paid to victims to help them with their immediate financial needs in the wake of the 7 July bombings."
The main source of compensation remains the government's criminal injuries compensation scheme.
Some of the most badly injured in the attacks, which killed 52 people and injured more than 700, have told their lawyers they face financial hardship because of up to 15 months delay before they receive money.
Colin Ettinger, partner at Irwin Mitchell solicitors, which has 14 clients who were involved in the bombings, said: "The shortfall will be monumental.
"The other key thing is that people really need the money now and they really need interim payments from the criminal injuries compensation board of some substance."
