That firm I linked to goes on to say that they have only a couple of clients who bothered to register the deed poll with the Court.
"In England and Wales, a Deed Poll may voluntarily be registered in the Central Office of the High Court. This means that the name change would also be advertised in the London Gazette. Registration of Deed Poll paperwork is regulated by the Enrolment of Deeds (Change of Name) Regulations 1994, Statutory Instrument 1994 No. 604.
However, it is absolutely not a legal requirement. We have only ever had a couple of clients who have opted to enrol their Deed Poll."
It sounds as though it is best to get some extra copies of the deed poll for sending to passport office, banks etc. Unless you want to risk sending the original one
