Company Setup Checker

Get a recommended UK business structure based on your expected turnover, risk profile and growth plans.

Short answer

Setting up a UK limited company costs £50 direct with Companies House (£12 online) and takes 24 hours. You'll need: a company name, a UK registered office, at least one director (16+), at least one shareholder, a SIC code, and PSC details. After incorporation: register for Corporation Tax (within 3 months of trading), open a business bank account, and consider VAT and PAYE.

Calculation method, coverage and version

Inputs used: Expected first-year turnover, How many people are involved?, Liability risk in your sector, Will you need outside investment?, Will you raise via SEIS/EIS or hire with share options?.
Calculation approach: The calculator applies the rules and assumptions described in “How it works” to the values you enter. Rounding can cause small differences from an official or provider calculation.
Coverage: Business Startup Tools. UK nations, tax treatment, local rules and provider criteria can differ; check the official sources shown below before acting.
Content version: No page-specific review date is currently published. Treat the result as indicative and verify current rules independently.

Not included unless explicitly requested: personal circumstances not entered, provider discretion, future rule changes, professional fees and case-specific exceptions. Read the full calculator methodology.

How it works

The checklist walks the full sequence — name check → incorporation → bank account → tax registrations → accounting software → insurance — and flags decisions that have long-term tax or legal implications (share structure, director/shareholder split, accounting reference date).

Worked example

Solo founder setting up a consultancy: incorporate via Companies House (£12), open Tide/Starling business account (free), register for Corporation Tax, start with FreeAgent (£19/mo), get £1m PI insurance (£250/yr). Total day-one cost: ~£300.

Who should use this

•First-time founders incorporating
•Sole traders moving to limited
•Contractors setting up a PSC

Common mistakes

×Using your home as registered office without privacy filtering — it appears on public record
×Issuing 100 shares of £1 each — locks up cash if undercapitalised
×Missing the Confirmation Statement deadline (£40 fine + risk of strike-off)

Yes — most small companies have one person doing both.
