What this incorporation checklist covers

This is a free, interactive company formation checklist that mirrors the actual online registration flow on gov.uk — broken into the same logical sections you'll encounter when you click through. It covers every detail Companies House asks for: company particulars, director and PSC information, shareholder and share structure, and the Corporation Tax questions HMRC bundles into the same form.

We built this tool because the gov.uk service doesn't tell you what it's about to ask until you're already inside it. Every time you get stuck halfway, you either abandon the session or fill in placeholder answers you'll later have to correct on the public register. Working through this new company setup checklist before you start means you finish the application in one pass.

Why a pre-registration checklist matters

Registering a UK limited company is essentially a one-shot process. You pay £100 when you submit, and the answers you give — SIC code, registered office address, share structure, articles of association — appear on the public Companies House register for anyone to see. Changing them afterwards is possible but each correction is a separate filing, sometimes with its own fee.

A thorough company registration checklist also prevents the most common cause of a stalled application in 2026: missing identity verification. Every director and every person with significant control (PSC) must now hold an 11-character personal code from GOV.UK One Login before they can be appointed. Without it, the registration form will refuse to let you proceed past the director section.
