Search on Equifax credit Report

There is no category for this so have posted on a few topics - I had an alert today on my credit report in the second table search.
Capita Employee Benefits Ltd - Beneficiary Trace does anyone know what this is as I have not agreed to this company does this search.

I spoke to Equifax and they could not give me any information and to contact the company but they have no contact information available.

Does anyone know or had this in there report

Thanks
