Those already being paid a disability benefit which qualifies for the support will receive the funds automatically. The vast majority of those eligible are expected to receive their payment by the start of October, the UK Government has said.
People with disabilities often face higher related costs, such as care and mobility needs.
Those who may be eligible for the payment include people receiving the disability living allowance, personal independence payment, attendance allowance, Scottish disability benefits (adult disability payment and child disability payment), Armed Forces independence payment, constant attendance allowance, or the war pension mobility supplement.
The money is part of a package of support for households as bills soar.
More than eight million eligible households in receipt of means-tested benefits received the first of two automatic cost-of-living payments of £326 from July 14.
The second means-tested payment of £324 will be issued later this year.
From October 1, a new energy price guarantee will mean average households will spend no more than £2,500 a year on energy for two years.
News of the guarantee was immediately overshadowed by the death of the Queen, leaving some questions about the support outstanding.
More measures to help households and businesses are expected this week. People are also urged to be aware of scammers targeting those expecting cost-of-living help.
Payments will be automatic, so people should be wary of messages from fraudsters asking for personal details.
