Question about Postgrad references

silly problem but I'm applying for a masters. I sent the applications off. I do have references but I just remembered a potential issue:
the name on my passport and the name on my degree are different (i had a complete name change a while back) thats fine, I attached a deed poll to each application to explain and it hasn't caused any issues. But for two of them, I had to put down my passport name. But if they use that name, my references will have no idea who theyre talking about
The attached uni transcript has my current name. But is it too much to assume they'll remember to use that name when asking for references? I thought about emailing admissions with a heads up but is that rude?
If it's relevant, I'm applying to swansea,northumbria and queens belfast.
Northumbria has already emailed me and they used the deed poll name so I'm more worried about the other two
apologies for any typos

easy option is to phone or email your referees and let them know both names.
