How to Register a UK Company in 2026 Without Delays or Rejections

Registering a UK company should take 24 hours. For a growing number of first-time founders in 2026, it's taking much longer — because of one step almost every older guide leaves out. Here's how to register a UK company correctly the first time, without the resubmissions and delays catching everyone else out.

Why Company Registrations Are Getting Rejected in 2026

Two rule changes are behind most of the rejections and delays this year. Founders following outdated guides, or rushing through the application, are missing a step that Companies House now enforces strictly: identity verification. Without it, the application is simply refused — no exceptions, no partial approvals.

The New Rules You Need to Know

Identity Verification for Directors

Since 18 November 2025, every director and every person with significant control (PSC) must verify their identity before the company can be incorporated. This is done through GOV.UK One Login or via an authorised agent, and it produces a personal verification code that has to be included with the application. Miss this, and the filing won't go through — it's not a formality, it's a hard requirement.

Updated Companies House Fees

The standard online filing fee doubled from £50 to £100 on 1 February 2026. Same-day filing costs £156, and paper filing costs £124. The fee charged is based on the date your application is processed, not the date you submit it.

How to Register a UK Company: The Correct Order of Steps

Doing these out of order is one of the most common causes of delay:

1. Choose your company name and structure
2. Verify identity first — for every director and PSC, before you do anything else
3. Confirm your registered office address and registered email address
4. Appoint directors, shareholders, and set your share structure
5. Assign a SIC code
6. File Form IN01 online
7. Receive your certificate of incorporation

Documents and Information to Prepare in Advance

• Proof of identity for each director and PSC (for the verification step)
• A UK address that qualifies as an "appropriate address" for your registered office
• A registered email address
• Shareholder and share structure details
• A SIC code that accurately matches your business activity

Having all of this ready before you start the application removes almost every common cause of delay.

How Long Registration Takes (And How to Avoid Delays)

Filed correctly, online registration is usually approved within 24 hours. The delays people run into almost always come from one of these:

• Starting the application before identity verification is complete
• Using a registered office address that doesn't meet the "appropriate address" standard
• A company name too close to an existing one
• Mismatched details between the application and supporting information

Avoid these, and there's no reason your registration should take longer than a day.

Should You Register Yourself or Use a Formation Agent?

Filing directly costs only the £100 statutory fee, and plenty of founders do it themselves without issue. But if this is your first time, or you're not confident navigating the identity verification process, a formation agent handles the whole application for you — checking every detail before it's submitted, so there's nothing left to reject.

Get Your Company Registered the Right Way

The process itself hasn't gotten harder — it's just added one non-negotiable step that catches people who skip it. Get identity verification done first, have your documents ready, and file online. If you'd rather not risk a rejected application, our formation team files these correctly every day and can have your company incorporated without the back-and-forth.
