If you receive a postcode error when submitting an SDLT return, this is most likely because the postcode does not exist on the Land Registry's system. There are two common causes.
The postcode is incorrect: Check the postcode with your client to confirm it has been entered correctly. If the postcode is wrong, correct it and resubmit the return.
âThe property is a new build: If the postcode is correct, the property may be a new build whose postcode has not yet been registered with the Land Registry. In this case, you will need to contact the Land Registry directly to have the postcode added to their system before you can resubmit.
