All websites should be accessible to disabled users, not only for ethical and commercial considerations, but also for legal. The Equality Act 2010 (EQA) prohibits discrimination from providers of services, good and facilities (EQA Section 21(1)). In 2011 the Human Rights Commission published a Statutory Code of Practice for "Services, public functions and associations" under the EQA explicitly stating that commercial websites are included in the scope of the EQA for the provision of services.
