What Are Companies House Name Matching Rules in the UK?

Companies House matches company names using exact text comparison, ignoring case, spaces, and common punctuation. Names match if they share the same core words and sequence, preventing duplicates. Follow these rules to reserve a unique name successfully.

This direct matching ensures no two identical or substantially similar names coexist on the UK register.

What Counts as a Matching Company Name at Companies House?

Companies House deems names matching if they are identical after removing spaces, symbols, and converting to uppercase. The system flags names like "ABC Ltd" and "ABC Limited" as matches due to shared root text.

The matching algorithm scans the exact sequence of letters. It strips non-alphabetic characters first. Then it compares the resulting strings character by character.

Register officers review flagged names manually. They check for sensitive words like "Royal" or "Bank" separately. This process blocks 92% of duplicate submissions instantly.

Core words drive the match. For example, "Tech Solutions UK Ltd" matches "TechSolutionsUK Limited". The system ignores "Ltd" and "Limited" as standard suffixes.

How Does Companies House Ignore Formatting in Name Matching?

Companies House disregards case sensitivity, spaces, hyphens, and apostrophes during matching. "My-Business" equals "MyBusiness" and "my business". This standardizes comparisons across submissions.

The algorithm normalizes text upfront. Uppercase conversion eliminates "Apple Ltd" versus "apple LTD" discrepancies. Space removal treats "Tech Solutions" as "TechSolutions".

Punctuation drops out entirely. Hyphens in "Well-Known" become "WellKnown". Apostrophes in "O'Brien Services" simplify to "OBrienServices".

This rule applies to all 4.5 million active UK companies. It prevents formatting tricks from evading checks. Submitters must verify uniqueness post-normalization.

Which Words and Suffixes Does Companies House Exclude from Matching?

Companies House automatically excludes legal suffixes like Ltd, Limited, PLC, and LLP from matching. It also ignores "The" at the start and "&" symbols, focusing on substantive name elements.

Suffix exclusion streamlines checks. "ABC Ltd" matches "ABC Limited" solely on "ABC". Officers confirm this in 85% of reviews.

Prefix "The" drops first. "The Widget Factory" matches "Widget Factory". Ampersands convert to "and": "Smith & Jones" equals "Smith and Jones".

Numbers remain intact. "Version 2.0 Tech" matches only exact numeric variants. Acronyms like "UK" stay as-is unless identical.

What Sensitive Words Trigger Extra Companies House Scrutiny?

Words like Royal, Bank, University, and Police require Companies House approval before name reservation. Submit evidence of entitlement or permission to use them.

Licensing bodies oversee these terms. The Royal warrant holder verifies "Royal" claims. Financial regulators check "Bank" or "Insurance".

Companies House rejects 78% of unauthorized sensitive word applications. Provide letters from authorities. Approval takes 5-10 working days.

Examples include "National", "British", and "International". Pair them with evidence. This protects public trust in registered entities.

What Happens If Companies House Rejects Your Name for Matching?

Companies House issues a rejection notice citing matching rules. Revise the name by adding descriptors or numbers, then resubmit the reservation application.

Rejections cite specific matches. Officers explain the conflicting name. 65% of rejections resolve with minor tweaks.

Add geographic terms like "Lahore Tech" or numbers: "TechV2 Ltd". Avoid abbreviations that normalize identically.

Appeal rare cases with evidence of distinction. Resubmission costs £12 standard fee. The process repeats until approval.

Can You Reserve a Similar Name Without Violating Matching Rules?

Reserve similar names by differentiating core words, adding unique descriptors, or using non-matching suffixes. Companies House approves if normalized text differs substantially.

Differentiation requires 2-3 distinct characters. "Fast Delivery Ltd" clears if "FastDelivers Ltd" exists. Substantive changes pass 82% of reviews.

Incorporate locations: "London Fast Delivery". Numbers help: "Fast Delivery 24/7". Acronyms alone fail without expansion.
