Debenhams has launched a new campaign with National Autistic Society to encourage other retailers and businesses to hold autism hours.
The annual campaign will begin on October 5.
On October 8, between 11am and 12 noon, the department store chain will aim to create a more autism-friendly shopping experience by turning down music and dimming bright lights.
Debenhams stores will also be sharing information about autism with staff and customers.
According to National Autistic Society, there are around 700,000 autistic people in the UK and 64 per cent of them avoid going into stores.
