No. You can have a divorce based on five (or more) years' separation without your wife's consent and regardless of whether she can be found or not. However, in a case where the other spouse cannot be found the court needs to be satisfied that every reasonable effort has been made to locate her, that no method of substituted service would work and therefore that the divorce can proceed without her having been served with the divorce petition.
This additional step is unusual so (a) a court will scrutinise it carefully and (b) it will take time because courts are not quick at the best of times. So a divorce in these circumstances will take as long as any other divorce (and none are quick these days because courts are staffed by civil servants who will not be rushed at the best of times) PLUS there will be the additional time it takes to get a court to agree that the divorce should proceed without your wife knowing about it.
