UK Startup Lifecycle: From Incorporation to First Hire

Last verified: 2026-05-02

A UK private limited company can be incorporated in one working day — but the company is not “ready to trade” on day one. From the Certificate of Incorporation under Companies Act 2006 s.15 to issuing a Section 1 statement to a first employee under Employment Rights Act 1996 s.1, there is a sequenced compliance pipeline. This article walks the lifecycle end-to-end.

Quick Answer (TL;DR)

A typical UK startup lifecycle in 2026:

1. Day 0 — Incorporate on Companies House Web Filing (digital, £100, ~24h)
2. Day 1–7 — Open business bank account; issue founder share certificates; set up statutory registers
3. Day 1–14 — Lease an office or registered office address; negotiate any commercial lease
4. Day 14–90 — Register for Corporation Tax with HMRC within 3 months of trading
5. Day 30–60 — Set up payroll (PAYE) before first payday
6. Day 60–90 — Right-to-work check, draft employment contract, issue Section 1 statement, register for pension auto-enrolment
7. Year 1 anniversary — File first confirmation statement (s.853A); 21 months after incorporation, file first accounts (s.442)

Stage 1 — Incorporation (Day 0)

Statute: Companies Act 2006, ss.7–16.

A UK private company limited by shares is formed when:

• One or more subscribers sign a memorandum of association (s.8), and
• The Application for Registration (the IN01 information set) is filed with Companies House (s.9), accompanied by the Statement of Compliance (s.13).

Practical sequence on the Web Filing service:

1. Choose a company name — search availability at https://find-and-update.company-information.service.gov.uk/company-name-availability. Section 66 disregards punctuation and “Ltd”/“Limited” suffixes, so “North-Wood Ltd” and “Northwood Limited” are the same.
2. Choose a registered office — UK physical address, not PO Box (Companies Act 2006, s.86 as amended by ECCTA 2023).
3. Decide on directors — collect for each: full name, date of birth, nationality, occupation, residential address (kept private), service address (public). Each director must complete identity verification under ECCTA 2023.
4. Identify all PSCs — under Part 21A and Schedule 1A.
5. Decide on share capital — typical startup: 100 ordinary £0.01 shares (£1.00 issued capital).
6. Adopt model articles (default) — under SI 2008/3229.
7. Provide a registered email — required since 4 March 2024 (s.88A).
8. Pay the £100 digital filing fee.
9. Receive the Certificate of Incorporation (s.15) — usually within 24 hours.

Outcome on Day 0:

• Certificate of Incorporation (s.15(1)) — “conclusive evidence” of registration
• 8-digit Company Number (permanent)
• Memorandum, articles, and IN01 published on the public register

Stage 2 — Banking and Statutory Registers (Day 1–7)

Banking. UK banks now require all directors and PSCs to have completed identity verification. Non-resident directors should consider fintech alternatives early:

• Wise Business
• Tide
• Revolut Business
• Mettle (NatWest)
• Monzo Business

A traditional high-street business account often takes 2–6 weeks to open and may require a UK-resident director.

Issue founder share certificates. Companies Act 2006, s.769 — the company has 2 months from allotment to issue share certificates to subscribers. Best practice: issue on day 1.

Set up statutory registers (kept at the registered office or a SAIL — Single Alternative Inspection Location):

• Register of members (s.113)
• Register of directors (s.162)
• Register of directors’ residential addresses (s.165)
• Register of PSCs (s.790M)

Stage 3 — Corporation Tax Registration (within 3 months of trading)

Statute: Corporation Tax Act 2009 + HMRC administrative rules.

Every UK company is UK-resident by reason of incorporation under Corporation Tax Act 2009 s.14. You must register for Corporation Tax with HMRC within 3 months of becoming “active” (i.e., starting trading or otherwise generating income).

How to register:

• https://www.gov.uk/limited-company-formation/set-up-your-company-for-corporation-tax
• Provides HMRC with your company’s start date for Corporation Tax (CT41G replaced by online process)

HMRC issues a Unique Taxpayer Reference (UTR) — the company’s permanent CT identifier. The UTR is sent by post to the registered office.

Corporation tax rates (FY 2026):

• Profits up to £50,000: 19% (small profits rate)
• Profits over £250,000: 25% (main rate)
• Marginal relief tapered between £50,000 and £250,000

Stage 4 — Office or Workspace (Day 14–60)

Most UK startups operate in one of three patterns:

A commercial lease under LTA 1954 carries automatic renewal rights (“security of tenure”) unless the parties contract out via the s.38A statutory declaration procedure before the lease starts. Most landlords require contracting-out for short-term leases (1–5 years).

Reference — LTA 1954: https://www.legislation.gov.uk/ukpga/Eliz2/2-3/56

Stage 5 — VAT Registration (when threshold approached)

Statute: Value Added Tax Act 1994 + Finance Act 2024 thresholds.

The VAT registration threshold is £90,000 of taxable turnover in any rolling 12-month period (effective from 1 April 2024). Voluntary registration below the threshold is permitted and often beneficial for B2B startups.

How to register:

• https://www.gov.uk/register-for-vat
• Standard rate 20%; reduced rate 5%; zero-rated and exempt categories

VAT is filed via Making Tax Digital (MTD) — quarterly digital submissions through compatible software (Xero, FreeAgent, QuickBooks, Sage).

Stage 6 — Preparing for the First Hire (Day 60–90)

This is where the startup transitions from “founder LLC” to “employer”. Compliance compounds.

6-1. PAYE Registration

Before the first payday, the company must:

• Register as an employer with HMRC: https://www.gov.uk/register-employer
• Set up payroll software (or appoint a payroll provider)
• Operate Real-Time Information (RTI) submissions to HMRC on or before each payday

If the company is engaging only directors-employees (e.g., founders paying themselves), PAYE is still required if any director is paid above the lower earnings limit.

6-2. Right to Work Check

Statute: Immigration, Asylum and Nationality Act 2006 ss.15–25.

The check must be done before employment begins. Civil penalty up to £45,000 per worker for first breach, up to £60,000 for repeat. Two routes:

6-3. Section 1 Written Statement

Statute: Employment Rights Act 1996, s.1.

A Section 1 written statement of particulars is a day one right for both employees and workers. It must be provided “no later than the beginning of the employment”. A well-drafted contract of employment satisfies the s.1 requirements; issue it on or before the first day.

Mandatory contents (s.1(3)–(4)):

• Names of employer and employee
• Date employment began (and continuous employment date)
• Pay scale or rate; pay interval
• Hours of work
• Holiday entitlement (5.6 weeks pro-rata under WTR 1998)
• Job title or brief description
• Place of work
• Probation period (existence, conditions, duration) — added 6 April 2020
• Required training, paid if applicable
• Sickness absence and pay terms
• Pension scheme particulars
• Notice required to terminate by either party
• Disciplinary and grievance procedures (or where to find them)

Reference: https://www.legislation.gov.uk/ukpga/1996/18/section/1

6-4. Pension Auto-Enrolment

Statute: Pensions Act 2008 (Part 1).

Every UK employer must auto-enrol “eligible jobholders” — aged 22+ to State Pension age, earning above £10,000/year — into a qualifying pension scheme.

• Total minimum contribution: 8% of qualifying earnings (employer min 3%; total min 8%)
• Employer must enrol within the auto-enrolment “duties start date” (date of first pay) plus any postponement period (max 3 months)
• Re-enrolment every 3 years for opt-outs

6-5. Employer’s Liability Insurance

Statute: Employers’ Liability (Compulsory Insurance) Act 1969.

Mandatory from the day the company has any employee (with very narrow exceptions for close-family-only employers). Minimum cover £5 million; market practice is £10 million.

6-6. National Minimum Wage / Living Wage Compliance

Statute: National Minimum Wage Act 1998.

From 1 April 2026:

• National Living Wage (21+): £12.71/hour
• Lower bands for 18–20, 16–17, and apprentices

Stage 7 — Post-Hire Operating Cycle (Year 1)

Common Pitfalls — Gyoseishoshi View

1. Trading before Corporation Tax registration. HMRC penalty up to £100 + percentage of unpaid CT for “failure to notify”. Register within 3 months of becoming active.

2. Issuing Section 1 statement late. Day one right since 6 April 2020. If you do not have it ready before the first day, you have already failed.

3. PAYE registration delay. Without PAYE, you cannot legally pay any employee — including yourself as founder-director. Register at least 4 weeks before first payday.

4. Forgetting the confirmation statement. 12 months + 14 days after incorporation. Failure leads to “proposal to strike off” — and an automatic struck-off company loses its bank account, contracts, and assets.

5. Right-to-work checks performed AFTER hire. The statute requires “before employment begins”. Doing it on day 1 of work is too late.

6. Mixing director loans with salaries. Director-shareholder dividends are tax-efficient but must follow the dividend procedure (board resolution, sufficient distributable reserves under Companies Act 2006 s.830) and be reported on the SA102 personal tax return.

Conclusion

A UK Ltd can be incorporated in a day, but the first employment hire is the milestone that separates a “shelf company” from an “operating business”. Between Day 0 and Day 90, eight separate statutes intersect: Companies Act 2006, ECCTA 2023, Corporation Tax Act 2009, Employment Rights Act 1996, National Minimum Wage Act 1998, Pensions Act 2008, Immigration Asylum and Nationality Act 2006, and Employers’ Liability (Compulsory Insurance) Act 1969.

For founders preparing the paperwork, the rule of thumb is: the easy bit is incorporating; the hard bit is hiring. Begin the right-to-work, PAYE, and Section 1 preparation at least 30 days before the candidate’s start date.
