To whom it may concern
Your visitors policy is not in line with current guidance.
NHS England’s visitor guidance was changed to permit access to “people who are in attendance to support the needs of the patient, for example a familiar carer/supporter/personal assistant”.
Here is the guidance: https://www.england.nhs.uk/coronavirus/publication/visitor-guidance/
Following campaigning by dozens of disabled activists, this change was made to ensure that disabled people were not put at unnecessary risk, and to ensure that hospitals met their legal obligations under both the Equality Act 2010 and the Human Rights Act 1998.

Please change your policy to respect the needs and rights of disabled people and ensure that your staff are able to carry out their roles in a lawful manner.
