How much does it cost to start a limited company in the UK?

The only mandatory cost is £100— the Companies House digital incorporation fee. Every other cost is a choice. Here's what each optional part really costs in 2026, and where the “cheap formation” offers hide their margin.

The short version: £100 to Companies House is unavoidable. A working launch stack — banking, domain, professional email, basic website — can be assembled from roughly £150 self-service, or done for you from £299 (formation + free business banking) to £849 (the full foundation) with a fixed-price partner. Identity verification is free but mandatory.

The mandatory cost: £100

Companies House charges £100 for standard digital incorporation. That fee is the same whoever files it — you, an accountant, or a formation agent. Since 18 November 2025 incorporation also requires every director and PSC to complete identity verification, which is free via GOV.UK One Login but cannot be skipped.

The optional costs, itemised

The ongoing costs nobody mentions

  • Confirmation statement — £34/year filed digitally. Miss it and the company can be struck off.
  • Annual accounts — free to file, but most trading companies pay an accountant to prepare them.
  • Corporation tax registration — free, within 3 months of starting to trade.

Skip the spreadsheet. Launch fixed-price.

Formation + free ANNA business banking is £299. The full Foundation package — formation, ID verification, secure workspace, domain and consultancy — is £849. No VAT is added: ProSolve is not VAT registered, so the price you see is the price you pay.

Frequently asked questions

Can I start a UK limited company for free?+

No. The Companies House digital incorporation fee is £100 and there is no free route. Some formation agents advertise "free" formation but recover the fee elsewhere — check what the total at checkout actually is.

What does a limited company cost per year after setup?+

The recurring statutory cost is the confirmation statement fee — £34 per year filed digitally. Beyond that, typical running costs are optional: accountancy (commonly £300–£1,500+/year), registered office services, domain renewal, and any software subscriptions.

Do I need an accountant to form a company?+

No — incorporation itself is a form-filling exercise you can do directly or through a formation partner. An accountant becomes valuable for ongoing corporation tax, payroll and VAT compliance once you are trading.

Is a business bank account a legal requirement?+

A limited company is a separate legal person, so it needs its own account in practice — mixing company and personal money creates accounting and legal problems. Free business accounts exist: ProSolve formations include an ANNA business account at no extra cost.

What about the identity verification requirement?+

Since 18 November 2025 every director and PSC must verify their identity with Companies House before incorporation completes. Verification itself is free via GOV.UK One Login — see our dedicated guide for the step-by-step process.
