If you are a carer of a disabled Person or Child above the age of 8 Years old you can get free access to the vast majority of UK cinemas when accompanying the said disabled person.
The disabled Person needs to be in receipt of disability benefits, DLA, AA, etc..
Its very simple to get you go to https://www.ceacard.co.uk/ and complete the on-line application, alternatively you can complete a postal application too.
The application is for the the disabled person so any responsible adult can be considered the carer, you DO NOT need to be in receipt of carers allowance.
There is an admin cost of £6.00 per application. which is less than a cinema ticket, so pays for itself after one screening.
I use mine for my autistic boys aged 10 and 14 who while enjoy the cinema could very easily be taken advantage of in the wrong situations so need a responsible adult to accompany them.
Go to https://www.ceacard.co.uk/participatingcinemas.aspx and enter your postcode to see if your local cinemas are participating.
Also remember this is for genuine people who need to accompany a disabled person/s to the Cinema, do not try to take advantage of these schemes as they rely on the goodwill of the cinema and the support of the scheme, fraudulent applications could ruin this in future for genuine users of the scheme.
