County access consultant says people with access issues could be deterred from shopping locally.
East Yorkshire businesses are being urged to make their shops more accessible for disabled customers in the run-up to Christmas.
It's claimed in the UK the collective spending power of disabled people and their companions is worth £249 billion every year.
East Yorkshire access consultant Ian Streets says some residents are being put off shopping due to accessibility and are instead shopping elsewhere:
"Think about your offering, think about how you talk to and treat your customers. think about where you put your Christmas stock. Don't block your aisles with all your stock so that people who need access assistance or a wheelchair or any other form of mobility aid that you are obstructing."
