Ian,,you should have started to bend those side branches down during the summer and to finally pull and tie to horizontal in August. Spurs would then form on those laterals.
your vertical main shoot will then produce buds and these....two, one each side,....are,allowed to grow vertically at first but then to duplicate as before.
each tier is made one per year
I grew mine as maidens. You can bespoke your espalier to fif your framework exactly and fruit production is heavy.
