Change of DOB for Refugee how easy is it?

[nihad]

Hello everyone


I need some advice, l would like to correct my date of birth, when l was born in Iraq l was born in a village and didn’t have birth certificate for a year and when my parents went to register me they just said date of birth is 1st of January which is not correct, when I came to Uk my Iraqi passport shows date of birth 1st of January and whenl was granted Refugee status on my BRP shows DOB 1 of January,

When l claimed asylum on my original statement to home office l did mention this mess up on my birthday and l told them the actual Birth date,
How easy would it be to change my Birth date on BRP to the actual that home office already awarw of?

Many thanks
