A man who lost both legs and an eye in the London bombings has said he is disgusted he has to rely on the charity of friends and family for his future.
Mr Biddell was caught in the Edgware Road blast
Daniel Biddell, 27, was speaking ahead of the London marathon where many of those he now depends on will be raising money for him.
He said the compensation system was not "geared up for a terrorist attack".
The Home Office said it was looking to change the system so the most serious cases receive more compensation.
A statement said that last year a consultation document was published proposing "that in future the most serious cases should receive higher levels of compensation to help ensure their potentially life-long needs are met."
A total of £9m was also given in donations to the London Bombing Relief Charitable Fund (LBRCF).
In his first television interview since the bombings nearly ten months ago, Mr Biddell told the BBC the money he had been given from the Criminal Injuries Compensation Authority (CICA) was not enough.
Mr Biddell would not disclose the amount of compensation he has received from either the LBRCF or the CICA.
So far the CICA has made 106 payments totalling more than £1m to victims of the London attacks in which 52 people were killed and hundreds injured.
"I think it's disgusting. The way the compensation is set up and run is disgraceful.
"What happened was extraordinary and I hope it never happens again but if it does people are going to be in the same situation.
"What they offer in compensation payments is inadequate. It isn't enough to rebuild my life and offer any security."
Mr Biddell, of Upminster in Essex, spent five months in a coma after suffering horrific injuries in the blast at Edgware Road.
"There's no amount of money that.. would replace what I've lost.
"I would give everything I own to go back ten months and not get on that train but that's not an option.
"I need help and I need support but the people who are in a position to do that are not interested."
He said that without the money from the London bombing relief fund he would not have a home to go to.
Mr Biddell called for the government to review the system in order to assess what support people need, besides financial help.
The Home Office has previously proposed that the Criminal Injuries Compensation Scheme should remove the £500,000 compensation award limit.
It also said thousands of people who suffer minor injuries as a result of crime may no longer be entitled to cash compensation.
Instead they would receive practical help such as counselling or help with insurance claims.
