Assistance is available from the Social Fund of the Department of Work and Pensions (DWP), which may support individuals who meet the requirements needed.
To qualify, you must prove that you are the right person to take responsibility for paying the funeral bill – also, you must earn at least one of several eligible benefits and have insufficient funds to fund the funeral.
The DWP Funeral Benefit can include a fixed sum that can either cover a very simple funeral or contribute to a more conventional funeral. Your selected funeral firm will be able to advise you on the qualification requirements and the probable contribution available.
