"Total spending power of disabled people is estimated to be £80 billion in the UK alone."
The DDA makes it unlawful to treat disabled employees less favourably than others; makes it necessary to make adjustments to assist disabled customers and employees and requires service providers to take steps to remove or alter physical barriers, within reason, where they prevent access.
Through making these adjustments it will enhance your customer experience, not only meeting your legal requirements but also building customer loyalty.
