What if I've lost my Deed Poll?
If you lose a Deed Poll, you can simply request a new one and start using it! You will ne to re-sign it and get someone to witness it with you, but it will be as valid as your original. The only time this may not be the case if when you need to prove a previous name change. For example, if you need to prove you've been using your current name for a certain length of time, or were known by that since a certain date, you may need a "retroactive" Deed Poll. This is essentially a statutory declaration which will need to be witnessed by a solicitor. They will likely request some evidence that you have been using your current name since the stated date, which could be bank statements or a passport issued at the time.
