London Underground operates a policy that older and disabled customers can request assistance from station staff on arrival, without needing to book in advance – Turn Up and Go assistance.
They are aware there are times when customers don’t get the assistance they need to travel, and are asking older and disabled people to complete a survey about their experiences of Tube staff assistance.
The link to the survey is here.
If the survey is not accessible to you, you can email email@example.com and ask for somebody to call you to complete it over telephone / textphone.
The survey will be open until 31st March 2017, and you can complete it more than once.
