The insurers have already answered this with a number: four or six weeks, depending on the product.
What the policy documents actually say
The six-week option is the industry's own judgement about where NHS waiting stops being acceptable. Aviva's version says that if the NHS can treat within six weeks of the specialist recommending private treatment, you must use the NHS — and the discount for accepting that is meaningful.
Saga goes further and offers a four week wait as well as a six, which is the only four-week variant among the documents we hold. A shorter threshold means the policy pays in more situations, and costs more accordingly.
That framing is useful even if you never buy the option, because it tells you what the insurer thinks the private advantage is worth. Below the threshold, they consider NHS treatment an adequate substitute; above it, they will pay.
Waiting times vary enormously by procedure and by trust, so the national conversation about NHS waits is a poor guide to your own position. The relevant number is the wait for your specific procedure at your local trust, which your GP or consultant can usually indicate.
The catch, as always, is timing. Cover has to be in place before the problem appears. Once you are on a waiting list you have a diagnosed condition, which is precisely what a new policy will exclude.

The limit behind every answer here
None of this reaches a condition you already have. Cover is written for problems that arise after it starts, so anything you have symptoms of when you apply is excluded — permanently under full medical underwriting, or until a symptom-free period has passed under a moratorium. Chronic conditions are excluded by every insurer whose wording we hold. Figures quoted come from current policy documents and change at renewal, so check the document you are actually offered.
