No Company Number Required: A 30-Day Plan to Prove Your Idea Before You Incorporate

A company registration costs £50 and takes about fifteen minutes. That is not a barrier to entry, it is a trap. Because the moment the certificate lands in your inbox, you inherit annual accounts, a confirmation statement, director duties, a Corporation Tax obligation and a paper trail that has to survive years of scrutiny.

The founders who do best are usually the ones who spent a month proving demand first and formed the company second. Here is a practical way to run that month.

Week 1: Interview people who have no reason to be nice

Aim for twelve to fifteen conversations with people who have the problem you think you have spotted. Not friends. Not other founders. People who will be mildly annoyed if you waste their time.

Where to find them: LinkedIn outreach, relevant trade associations, local chamber of commerce events, Facebook groups for the industry, subreddits for UK trades and professions, or the queue at a trade show nobody else from startup-land attends.

Ask about the last time they dealt with the problem. What did they do, who did they pay, how much, and what annoyed them? Never pitch. If you are pitching, you have run out of questions and started seeking approval.

The output of week one is a single sentence describing a problem someone already spends money on. If nobody spends money on it, you have a hobby.

Week 2: Put a page up and mean it

Build a single landing page with one promise, one call to action, and — crucially — a price. Tools like Carrd and Framer cost less than a round of drinks; Shopify will run you around £25 a month.

Run three different headlines across a small paid campaign. Track clicks on the buy button, not just email sign-ups. A waitlist is cheap enthusiasm; a click on a £49 price is a genuine signal.

Week 3: Take real money, carefully

This is where the UK compliance details start to matter.

Do not use Ltd in your name yet. Trading as an unincorporated business is fine. Describing yourself as limited when you are not is an offence, and it should not appear on your site until you have a certificate of incorporation with that name on it.

Sole trader first is legitimate. Register for Self Assessment with HMRC, invoice under your own name or a plain trading name, and remember the £1,000 trading allowance covers small-scale income without any paperwork. Stripe and Square will onboard sole traders without drama, and once pre-orders start flowing, a business account with Starling, Monzo Business or Tide keeps things clean.

Consumer law applies the moment you take a deposit. Under the Consumer Contracts Regulations 2013, consumers get 14 days to cancel distance purchases. For pre-orders, you must state an expected delivery date; if you do not, the Consumer Rights Act 2015 defaults to 30 days. Taking money for something you cannot deliver for six months creates a real obligation, not a marketing stunt.

Collect emails properly. Publish a short privacy notice, say what you will do with the data, and check whether the ICO data protection fee applies to you. It is a small annual cost and an expensive thing to discover during a complaint.

Behave over the claims. The advertising codes apply to a shop with no revenue exactly as they apply to a FTSE company. No invented reviews, no fake scarcity counters.

B2B shortcut: a signed letter of intent or a paid pilot is worth ten waitlist sign-ups. Write it on one page. It does not need to be a work of art.

Week 4: Decide, then set up properly

The discipline is this — if the signals are weak, do not incorporate. A dormant company still files accounts and a £34 confirmation statement every year, and late filings generate automatic penalties. Many of the founders we meet have a shell company from 2023 that has never traded and now needs fixing.

If the signals are strong, set up in the right order:

1. Reserve the name and incorporate digitally for £50.
2. Complete director identity verification through GOV.UK One Login. This is now part of the incorporation process for new directors, so have your passport or photocard licence ready.
3. Register for Corporation Tax with HMRC, and for PAYE if you are paying anyone including yourself.
4. Open a business bank account in the company's name.
5. Agree the share split and sign a shareholders' agreement, especially if there are two or more of you.
6. Get IP assigned to the company in writing — code, designs, copy, everything created by a freelancer.
7. Get an accountant before your first year-end, not after.

One more watch-out worth knowing in advance: pre-incorporation contracts. A company that does not yet exist cannot sign anything, which means if you put your name on a lease or a supplier agreement before incorporation, you are personally on the hook for it under section 51 of the Companies Act 2006. Either sign as agent for the company to be formed, or wait.

The 30-day scorecard

• Strong: 10+ real problem interviews, 100+ qualified clicks, 20+ paying pre-orders or three signed LOIs, and a clear idea of what customers will pay.
• Worth another month: interest is there but the price is wrong, or you cannot articulate who the buyer is in one sentence.
• Stop: polite silence, no clicks on the price, and interview subjects who say your problem is interesting rather than expensive.

Things not to spend money on yet

A logo. A trademark (£170-plus per class, and you may pivot in six weeks). A lease. A website with eleven pages. A business coach. Quitting your job before the first invoice clears.

Validation is not a sign of caution — it is a demonstration of commercial judgement, which is exactly what investors, buyers and future employees want to see. Start Network's Operations & Compliance sessions run through this stuff in plain English every quarter; bring your half-formed idea and someone will stress-test it with you.
