Leasehold extension now waiting 15 months, can we get an update please

We completed on the extension of our leasehold in September 2022, we are still waiting for confirmation that this has been registered. We want to sell in spring, may we get an update please?

Lisa - The application to register a new lease (extension of lease is treated as surrender of existing lease and registration of new lease) is captured for registration under title number SGL836232 and is currently awaiting to be looked due to the delays that we have. 

If the registration has not been completed by the time you put the property on market then I suggest ask for it to be expedited - https://www.gov.uk/guidance/request-an-expedite
