Kira-Colleen - it's the local authority that manages postal addresses and yes, you would need to ensure that the register is up to date as a result.
You can complete form AP1 to change the property description.
You need to send us evidence from the street naming and numbering department of the Local Authority. Royal Mail documents are not acceptable as their delivery point address description can differ from the Local Authority registered address.
When submitting your application, please remember to tell us the address you would like a copy of the updated register to be posted to upon completion, as this can often be different from the property itself.
There is no fee for this application
