Checking business name availability means verifying 4 things: Companies House (company name), UK IPO (trademarks), domain registrars (web address), social platforms (brand presence). Skip one = risk expensive conflicts.

The 4-Step Verification Process

Each step eliminates different risk. Complete all four or face consequences later.

Businesses checking all 4 areas have 94% lower rate of naming conflicts vs those checking only Companies House.

Step 1: Companies House Check

Search Companies House database. Checks if identical company name exists.

What This Prevents

Rejection of company incorporation. Confusion with existing company. Inability to register limited company with your chosen name.

What This Doesn't Prevent

Trademark conflicts. Domain unavailability. Trading name disputes. Similar (not identical) company names.

Search UK IPO and EUIPO databases. Checks registered trademarks.

What This Prevents

Cease and desist letters. Legal disputes over brand usage. Having to rebrand after launch. Trademark opposition when you try to register.

Step 3: Domain Availability

Check .co.uk and .uk availability. Use Trademark Lens to check 15 extensions simultaneously.

What This Prevents

Launching business without matching domain. Using hyphenated or awkward domain. Losing traffic to competitor who owns your name.co.uk. SEO difficulties.

Warning: If YourName.co.uk is taken, seriously consider choosing different business name. 73% of UK customers will type YourName.co.uk when looking for you, even if your actual domain is YourName.uk or YourName.com.

Step 4: Social Media Usernames

Check Instagram, Facebook, LinkedIn, Twitter. Use Trademark Lens to check 12 platforms at once.

What This Prevents

Inconsistent brand presence. Customer confusion. Impersonation issues. Inability to claim your business name on social platforms.

What to Do With Results

All green = proceed confidently. Any red in same industry = choose different name. Red in different industry = consult trademark attorney. Domain taken but rest clear = decide if domain matters more than name.

The Decision Matrix

B2C business: Domain is critical, social usernames important. Change name if main domain unavailable. B2B business: Trademarks most critical, can work around domain issues. Social less important.

When to Compromise

Perfect name available everywhere = rare. Usually you'll face decision: keep name with alternative domain, or change name to get perfect domain.

Good Compromises

YourName.uk instead of .co.uk (if .co.uk taken). @YourNameOfficial instead of @YourName on Instagram. YourNameHQ.co.uk if YourName.co.uk taken.

Bad Compromises

Keeping name despite trademark conflict. Using your-name.co.uk (hyphenated). Accepting @YourName_UK_Official_123 on social platforms.
