Shouldn't this pull the most recent version of the user data on get? see https://gist.github.com/jcockhren/8762001 for supporting code.

views.py

class SettingsView(UpdateView):
    model = CustomUser
    form_class = UserForm
    #form = UserForm(self.instance)
    template_name = 'account/settings.html'
    success_url = '/account/settings'

    fields = ['first_name',
              'last_name',
              'email',
              'company']

    def get(self, request, *args, **kwargs):
        form = UserForm(initial=model_to_dict(CustomUser.objects.get(id=request.user.id)))
        return render(request, self.template_name, {'form': form})

    def get_object(self, queryset=None):
        return CustomUser.objects.get(id=self.request.user.id)
