Identity documents

It surely depends on what your mum needs proof of ID for? Perhaps check first whether her bus pass/birth certificate etc will do. A provisional driving licence isn’t free and isn’t always accepted as proof of ID.

I was allowed to use my expired passport to fly from Gatwick to Glasgow.

... my local medical centre (GP) were perfectly happy to accept my expired Passport as ID in order to access their online system - it expired years ago.

I think, depending on who's asking for the ID, you should simply ask them what they will accept.

I think Beautful is right here - and I believe a utility bill is more often than not something that most institutions / companies will accept.

Although I personally would be wary of using expired ID just check first. I have seen this on trip advisor , so copied it ... you could ask the company she needs to use ID & ask ... can only say one of 2 words yes of no. I worked in a bank many years ago & wouldn't then accept expired ID or provisional DL ... although things change ...

Expired or not, the passport is only being used as valid ID, not as a travel document, so should be acceptable.

Might be worth her while to apply for a provisional driving licence and use that as an ID. No need to learn to drive.

Great idea

I don't think she has to renew the passport your mum can use a Bank Statement showing her address or utility bill possibly from the last 6 months.
My neighbour showed his Council Tax bill when he needed proof of address and it was accepted.Hope you get it sorted as its quite expensive to renew a PP.

Bus pass has photo on plus any utility bill.
