I completely agree with all of the warnings here on this site that I've read about deVere. I have been on a De Vere plan for five years - worst investment I ever made. Promises of quarterly review - didn't happen. (Apparently there is a legal obligation to do a six-monthly review in Belgium - that didn't happen either.) I should have realised that something was up when they cold-called me after I had been their customer for four years. Then when we asked to vary payments into the plan they gave us wrong advice and completely screwed up the fee structure.
De Vere never implemented any request of ours that did not make them money, and clearly lost interest after we'd bought their recommended policy in the first place which is when they got their fees.
Significantly there is no place on the De Vere website to register complaints. Fortunately there are government agencies, including the police, who take a different view.
