Any lawyers out here at all?

[coldiris]

I am wondering if there are any lawyers out here who could give an opinion on one clause in a contract please?

You need to say what kind of contract OP. Employment, tenancy, services?

retail settlement agreement

I'm not sure I'd be using Mumsnet as my go to law source if it's anything serious 🤨

If you mean you have been offered a settlement agreement (employment) then your employer makes a legal fee contribution for you to be advised by a solicitor. Therefore take advice from a qualified expert at no cost to you, rather than randoms on the internet.
