He made the claim to Sunday Times reporters posing as potential donors.
He said £250,000 gave "premier league" access, including dinner with David Cameron and possibly the chance to influence government policy.
In the footage, Mr Cruddas is heard initially saying that it was not possible to buy access to the prime minister.
But he then goes on to discuss what access different size donations would get.
"Two hundred grand to 250 is premier league… what you would get is, when we talk about your donations the first thing we want to do is get you at the Cameron/Osborne dinners," he says.
He said the meetings were good for picking up "a lot of information", and that he would ensure suggestions were fed back to No 10.
"You will be able to ask him [Mr Cameron] practically any question you want.
"If you're unhappy about something, we will listen to you and put it into the policy committee at Number 10 - we feed all feedback to the policy committee."
