Ah I see, part of my previous role involved helping people find suitable employment, really if you are looking for a full time work from home job & especially if you are looking for an “entry level” job (which I assume this person will as you’ve mentioned that they will need fully trained) then your main/only options are going to be things like call centres, companies like EE, Sky, BT are pretty good for this, tend to have quick turn around on start dates and provide good training, but of course they are telephony jobs so the majority is going to be on the phone.
We were able to get some people into work from home admin/data entry jobs, however typically these posts (especially when full time WFH because there’s no hands on training) do require the candidate to have at least 1 years experience in a similar role, and to have some suitable qualifications to back it up.
There are other roles that do offer full time work from home in things like IT (broadly) but they all require a level of experience & qualifications from the off.
Some other options that might be worth considering, obviously depending on how this person would cope/manage, is civil service jobs. Typically now most of these jobs are hybrid, 2/3 days in the office and the rest from home, but job dependent the office days can be whatever the person needs them to be. Reasonable adjustments can always be requested so things like sitting alone if needed in a separate space, booking any meetings/calls in advance, anything that might mitigate the impact.
The biggest problem you’re going to have is that when you are looking for fully WFH jobs, for most other than call centre work the company will want candidates with experience of the job already and qualifications to back them up. When you are brand new to a totally new role then a company is less likely to want you at home all of the time because it’s harder to train, do shadowing, ask questions, learn from more experienced colleagues etc while sitting home alone x
