"I don't really know how these classes are run in the UK, but in the US, AOW is designed as an immediate follow-on to the OW class. People who wait and take it significantly later are often disappointed at the content."
This is a general statement that does not apply to all instructors or even agencies in the US. The disappointment comes when they find that the "Advanced" class is not and does not introduce new skills or require some degree of proficiency in basic skills before starting it. Few fresh out of OW students that I have not trained or that instructors who teach like I do have trained could get through my AOW class successfully. It is designed as a pass, fail, or practice and come back course. Not one that says " ok we did the dives, here's your card". I'm not the only one teaching an AOW like this but it does take some effort to find an instructor that does as I do. But we are out there.
Some agencies also require basic rescue skills that are included in their OW classes. There are other skills that they offer in their OW classes that others don't require until DM or not at all before going into the AOW class. So don't assume that all AOW classes are the same. They are not just as there are major differences in OW training among different agencies. It is often said that the instructor makes the difference and it's true. But it is also to a large degree how much freedom the agency gives that instructor and what their own minimum standards are.
The standards of my agency not only encourage but require us to go beyond the basics and to test on that for certification. Local conditions sometimes require very different skill sets. Look for a class that takes that into consideration and adds material to best suit that. And that requires you to meet those standards before they give you a card.
At the end you should be able to say you'd let your kids dive with someone trained to the same degree as yourself without you or a professional around.
