Still gathering requirements...
As ads says speak to the company if they are still around as the first port of call.
Also maybe try to find if a group has been formed here for your company/scheme provider.
Either way I would seek independent legal advice on your own situation rather than rely on what your scheme provider says if they are still around.
I'd be a bit dubious about any company saying they can kill off these discovery assessments If they're offering no win no fee then maybe but I was fed that line by my scheme provider for a long long time, and unfortunately the reality is a lot different.
