Below is the relevant extract from the Land Registry’s Public Guide 20 which describes who can verify your identity to the satisfaction of the Land Registry.
5.3 Verification of identity
You can have your identity verified by a conveyancer or at one of our customer information centres. You will need to take the identity evidence mentioned in section B3 of form ID1 or ID2 and a recent passport-size photograph with you (you will need 2 copies of the photograph if you are going to a conveyancer, because they will need a copy for their records). Your face must be clearly visible in the photograph. ID forms may be rejected if this is not the case. Land Registry does not charge a fee for this service, but a conveyancer may do so.
If you have your identity verified by a conveyancer and then lodge your application by post we may make additional checks to satisfy ourselves that everything is in order.
However to come within the definition of conveyancer in rule 217A of the Land Registration Rules 2003 an individual must be authorised under the Legal Services Act 2007 to provide conveyancing services; in effect they must have a practicing certificate.
If verification is given by a person who has made it clear on the ID form that they are retired or not practising as a solicitor, barrister etc, a requisition is likely to be raised for verification by a person who comes within the definition of conveyancer contained in rule 217A of the Land Registration Rules 2003.
5.3.1 Verification of identity at our customer information centres
If you are coming to Land Registry, please telephone customer support before your visit if you are unsure what evidence of identity you will need to produce and to make an appointment.
Our customer information centres are open between 8.30am and 6pm on Mondays to Fridays. You will always need to make an appointment giving us at least 24 hours’ notice. Appointments may be made by completing the ‘Appointment Request’ on our website or by telephoning Customer Support (see Contact details).
You must submit your application at the same time as verification at the customer information centre. This means that everyone who completes an ID1 or ID2 for that application must attend at the same time, and that the application requiring ID verification must itself be in order. If this is not possible, the parties who cannot attend should consider going to a conveyancer to have their identity verified before the application is submitted. Because of our security measures we will not process applications to change the register while you wait at our customer information centres. We will accept your application, and will either post notification of completion to you or contact you to collect this when it is ready, if you request this.
Please remember that fresh evidence of identity will have to be produced for each separate application if these are lodged at different times or at different local offices.
