Should You Change Your Address at Companies House for Privacy?

Changing your address at Companies House for privacy reasons can be a strategic decision, particularly if you wish to safeguard your personal information. By opting to use a different address as your company’s registered office, you can maintain a level of confidentiality, preventing your residential address from being publicly available. This separation can also serve to enhance your professional image, especially if you operate your business from a non-traditional setting.

Additionally, adhering to this practice ensures legal compliance, as having a registered office address is mandatory for companies but does not necessitate using your personal address. If you choose to modify your company’s registered office address for privacy purposes, be sure to follow the prescribed procedures set by Companies House to ensure accuracy and adherence to regulations.

Do Sole Traders Have to Be Registered With Companies House?

Sole traders do not have to be registered with Companies House, as it is primarily for limited companies and partnerships. However, they must register for self-assessment tax with HM Revenue & Customs (HMRC). This registration process ensures that sole traders are compliant with tax regulations and obligations.

Even though sole traders don’t need to be listed on Companies House, they still need to keep accurate financial records. These records help in reporting profits and losses accurately for taxation purposes. Being diligent in record-keeping is crucial for the financial health of a sole trading business.

While Companies House may not be necessary for sole traders, understanding their tax responsibilities and legal obligations is essential. By staying informed about these requirements, sole traders can effectively manage their businesses while remaining compliant with the law.


In the fast-paced world of business, keeping your company information up to date is crucial. Changing your address on Companies House is a simple process that can be done online or by mail. By ensuring that your registered office address is accurate and current, you are complying with legal requirements and maintaining transparency in your business dealings.

Remember to keep Companies House informed of any changes to your registered office address promptly.
