A Blue Badge is issued in a specific name and must match the holder's identity documents for enforcement purposes. After a deed poll, you should apply for a replacement Blue Badge in your new name to ensure it remains valid when parking wardens or police check it against your ID. The badge is issued by your local council, so you apply through the same authority that issued your original badge.
To apply for a replacement badge, contact your local council's Blue Badge team. You will need to provide your current badge, a certified copy of your deed poll, a passport-style photograph, and your current address. There is usually no fee for a replacement due to a name change, though this varies by council. Your badge number and eligibility assessment remain valid; you are simply requesting a badge with the updated name.
Your Blue Badge eligibility is completely unaffected by a name change, whether based on a qualifying benefit (higher rate DLA or PIP) or on a condition assessed by the council. You do not need a new eligibility assessment. If your badge is due for renewal soon anyway (badges are typically valid for three years), you may find it convenient to combine the name change with the standard renewal.
