So (all into days terms) your max pension with full service, including the State Pension, is 42k. But you could receive up to 53k before going into the 40% rate. And that would still allow your wife to receive/earn up to 35k. So you do have scope to add to your pension via AVCs without facing the higher rate at drawdown. Of course, if you were to receive significant promotion to bring your salary closer to 106k (in todays terms) it would be a much tighter call.
And if you are going retire early you should definitely look at AVCs. But it all depends on whether you can afford it.
