The short answer
A pre approval is a bank's conditional view of you as a borrower, given before you have chosen a property. It tells you the price band you are shopping in and it makes you a more credible buyer. It is not a final offer, and the valuation still sits between it and the keys.
What it actually tells you
A pre approval applies the two caps to you rather than to a property: how much your income supports inside the 50 percent debt burden limit, tested at the bank's stress rate, and what that implies at the loan to value ceiling for your buyer type.
That is genuinely useful. It turns a vague budget into a price band, and an agent treats an offer from a pre approved buyer differently from one without.
What it does not settle
It does not settle the property. The loan to value cap is applied to the lower of the price and the bank's own valuation, so a short valuation changes the cash you need after a pre approval, not before.
It is also specific to the bank that issued it and to the circumstances you declared. A new liability, a change of employer, or a different property type can all move it.

How long it lasts
Validity differs by bank, and we deliberately do not publish a single number here: we would rather tell you the figure for the bank you are actually going to than print an average that is wrong for most readers.
It is worth asking that question at the point of application rather than at the point of offer, because a pre approval that expires mid search costs you the search.
