Incorrect referee address on submitted application. Should I upload a cover letter explaining?

[Driver27]

I have already submitted my naturalisation application but haven't had the BRP appointment yet. I can still upload documents on the online portal.
One of the referees gave me the incorrect address, it was clearly a typo. Instead of No 118, I have put 18 on the application form. Since it is submitted, I can no longer ammend it.

Can I upload a cover letter explaining the error? Would that be sufficient or would I need to send them an email or something?

Thank you

Yes, explain the typo in the cover letter and upload it before you attend your biometrics appointment. Make sure it is correct on the referee form that you will upload.

Thank you for the reply.
I will upload a cover letter explaining it, however the referee form doesn't ask for the referee's address.
This is the form I'll be submitting - https://visas-immigration.service.gov.u ... on_MN1.pdf

Thanks

My apologies I misremembered the form. Yes just state the correction in the cover letter.
