This question already has an answer here:

My partner has been asked to submit passport details for a British passport he held in 1998 to support a British citizenship application for his son. He has been unable to locate the expired passport that he used at the time and so we're wondering if there is a way of accessing, at the very least, the passport number.

We're assuming this record might be held with a UK Visa/Immigration Office? Would anyone know if this is possible, and if so, how to go about getting such information? Many thanks.
