Hi Danny

I think you may struggle to find shadowing in these socially-distancing times, it's tricky enough at best, so the Covid risk provides even more resistance to someone else in the mix. Shadowing usually involves a bit more interaction than just following someone around and listening. Fo this reason Covid will be a problem. But even generally, it is an extra demand on the person being shadowed. I would not start with consultancies - they are going to be under far too much commercial pressure even normally.

Public sector organisations such as local councils, or housing associations may be a better bet. They are more used to having work experience placements and offering unpaid opportunities for others to learn. That said, councils have had general funding and H&S resource stripped away over the last 10 years, so be prepared for negatives. Is there something you can offer in return for the shadowing? For example, some database work, make a video of the SP or places visited, to help with one of their projects. 

You don't say where you have obtained your experience or what it relates to, but there may be something you have knowledge of which can provide a benefit to the shadowee (?). 

Although there are no physical meetings at the moment, local IOSH or other safety groups may offer information on local organisations where an opportunity could exist.
