One of the most fascinating aspects of the UK legal system is the freedom it grants individuals over their own identity. Under English common law, you have a fundamental right to be known by any name you choose, provided you are not doing so for fraudulent or illegal purposes. This leads many people in London and across the country to ask: "Do I actually need a deed poll, or can I just start using my new name informally?"
While the idea of an "informal" name change sounds appealing—no forms, no fees, and no waiting—the reality of life in 2025 is governed by digital databases, strict security protocols, and "Know Your Customer" (KYC) regulations. In this guide, we will weigh the pros and cons of informal versus legal name changes and explain why formalising your identity is the only way to ensure your new name is respected by the organisations that matter most.
The Informal Name Change: Freedom Without the Paperwork
An informal name change occurs when you simply start introducing yourself by a new name. This might be a nickname, a shortened version of your middle name, or a completely new identity that you use with friends, family, and on social media. Many people in the UK live perfectly happy lives with a "social" name that differs from the one on their birth certificate.
The Pros of Informal Usage
- Zero Cost: There are no documents to buy and no government fees to pay.
- Zero Commitment: You can "trial" a new name without making it permanent. If it doesn't fit, you simply stop using it.
- Social Flexibility: It allows you to separate your personal life from your legal records, which some find useful for online privacy.
The Cons of Informal Usage
- The Identity Gap: While your friends call you "Alex," your bank, employer, and the NHS still see you as "Alexander." This "split identity" can lead to significant administrative confusion.
- Travel Barriers: You cannot update your British passport with an informal name. If you book a holiday in your new name but your passport is in your old one, you will be refused boarding at the airport.
- Financial Roadblocks: Banks will not issue credit cards or mortgages in an informal name. To them, if it’s not on a legal document, it doesn’t exist.
- Professional Inconsistency: Using one name on your CV and another for your National Insurance (HMRC) records can raise red flags during background checks.
The Legal Name Change: Closing the Identity Gap
A "legal" name change is the process of executing a deed poll. This is a formal document that serves as evidence of your new identity. When you sign a deed poll, you are creating a legal paper trail that links your old identity to your new one.
The Pros of a Legal Deed Poll
- Total Recognition: A correctly drafted deed poll is accepted by 100% of UK government bodies, including HM Passport Office, the DVLA, and HMRC.
- Smooth Banking: With a deed poll, you can walk into any bank branch in the UK and have your accounts, cards, and loans updated to reflect who you are.
- Legal Protection: Under the UK GDPR, you have the "Right to Rectification." Once you provide legal evidence of your name change, organisations are legally required to update your personal data.
- Consistency: It eliminates the stress of managing two different names. One identity, one set of records, zero confusion.
The Cons of a Legal Deed Poll
- A Small Investment: There is a minor cost associated with obtaining a professionally drafted document (though with UK Name Change, this is as little as £19.49).
- Administrative Effort: You must proactively notify organisations of the change. However, this is significantly easier when you use our interactive dashboard to track your progress.
Why "Legal" is the Only Way for 2025
If you were living in the 1920s, an informal name change might have sufficed. However, in the 2020s, your identity is verified against national databases every time you use a service. Whether you are applying for a new job in London, renting a flat, or simply picking up a parcel from the post office, you are frequently asked to "prove who you are."
In the eyes of the UK government and the financial sector, an informal name change is essentially a "alias." While it isn't illegal, it isn't official. This lack of official status creates "friction" in your daily life. Every time you have to explain why the name on your debit card doesn't match the name on your email, you are wasting time and risking rejection.
"In 2025, your name is your primary key to the digital world. If that key doesn't match the locks on the Passport Office or your bank, you are effectively locked out of your own identity."

While an informal name change might be fine for social media, it will eventually let you down when you need to navigate the "real world." Whether it's the frustration of a rejected passport application or the embarrassment of having to use your "deadname" at a medical appointment, the drawbacks of informal usage far outweigh the convenience.
By executing a legal deed poll, you are making a powerful statement: This is who I am. You are giving yourself the gift of a consistent, legally protected identity that will be respected by every institution in the United Kingdom.
