🚫 Common Mistakes to Avoid When Starting a UK Business

Mistake #1: Using a Conflicting Company Name

Many first-time founders choose a company name that is either too similar to an existing one or breaches UK naming rules (e.g., using restricted words like "Royal").

Solution: Always check your proposed name against the Companies House database and seek approval if it includes sensitive terms.

Mistake #2: Ignoring the Need for a UK Registered Address

You must have a registered office address in the UK to incorporate your business. Foreign entrepreneurs often forget this and face rejection during registration.

Solution: Use a virtual office provider or engage with a UK-based consultancy for a compliant address.

Mistake #3: Overlooking Post-Incorporation Requirements

Incorporation is just the beginning. New companies often miss key requirements like tax registration, shareholder agreements, and setting up accounting systems.

Solution: Use professional setup services or follow a structured checklist like the one shared here:
