If/When we do have to have a f-2-f meeting think the best plan will be to insist on a Home Assessment. That way we get to control the situation, minimising exposure to one person – the Assessor – rather than be exposed to an enclosed public room where countless others are sitting or have sat, and ensure our own Covid-safe rules regarding safe distancing between people and cleaning surfaces afterwards.
The DWP might be reluctant to do this for everyone, but being in the ‘highly vulnerable’ group (even with vaccinations) should now be accepted as a reason to qualify for a Home Assessment.
