Property address on Title Deed different to local authority

My first floor leasehold flat has 2 slightly different first lines of address - the Land Registry has it as Flat 2, 26 Lyon Street and the local authority (and Royal Mail) has it as 26A Lyon Street.  I am currently trying to sell the property but the buyer’s solicitor has queried the 2 different addresses.  Will it be possible to update the address on the Land Registry and my Title Deed to 26A Lyon Street, to be in line with the local authority?  Is the AP1 form the way to do this?  Is it possible to change my address on the Land Registry without the freeholder of the property (and owner of the ground floor flat) having to also apply to change their address?  It is a terraced house that was split into the 2 flats 30 years ago.

Many thanks for your help.

Hannah - yes to all your Qs. Send the AP1 with a copy of the local authority confirmation re correct postal address.
NB - postal addresses are managed by the local authority for electoral roll purposes. Royal Mail and others then rely on that confirmed postal address for own needs

Hi Adam,

Thank you so much for your quick reply - that is so helpful!  Can I just check what would count as confirmation from the local authority?  Also, can I ask, will there be a fee for this?  And any estimation on how long it will take to process?  

Many thanks.

  

Hi Hannah - contact the council's street name and numbering department and ask them to confirm the postal address. That confirmation would be sufficient and send us a copy
