From Companies House to First Invoice: A UK Setup Guide

The first UK invoice rarely fails because of tax. It fails because something earlier in the chain — a registered office that cannot accept HMRC post, a PSC entry filed in the wrong shape, a bank application stuck on proof of address — quietly stops the company from operating. For an overseas founder, the British system looks deceptively friendly: incorporation can be done online in under a day. The harder work sits in the week after.

This piece walks through the decisions that actually matter, in the order they usually arrive.

Choosing the entity: Ltd or LLP

For most overseas founders, the realistic choice is between a private company limited by shares (Ltd) and a limited liability partnership (LLP). They are not interchangeable.

A UK Ltd is the default for trading businesses, SaaS, agencies, e-commerce and anything you might one day raise capital into. It has shareholders, directors, share capital and pays corporation tax. It is the structure investors expect and the one banks understand fastest.

An LLP is a partnership with limited liability — used mainly by professional services firms (law, accounting, consultancy) where members want tax transparency. Profits flow through to members, who are taxed individually. For a non-resident founder with no UK tax footprint, an LLP can create more reporting friction than it saves, and it is a poor fit if you plan to issue shares, grant options or take outside investment.

If you are unsure, start with a Ltd. UK Ltd incorporation is reversible into more complex group structures later; an LLP is harder to unwind cleanly.

The Companies House filing itself

Incorporation through Companies House is procedurally light but substantively dense. The form asks for:

1. Company name — check for trade mark conflicts before, not after. Names that imply regulated activity (bank, insurance, chambers) trigger additional approval.
2. Registered office address — must be in the jurisdiction of incorporation (England & Wales, Scotland or Northern Ireland). It must be an address where official post can be received and acknowledged. A residential address abroad will not work; a mailbox service that does not handle statutory post is risky.
3. Directors — at least one natural person, aged 16 or over. There is no UK residency requirement for directors, but a fully non-resident board makes banking harder.
4. Shareholders and share capital — most founders start with a small number of £1 ordinary shares. Over-engineering share classes on day one creates problems at the first funding round.
5. PSC register — the People with Significant Control register, discussed below.
6. SIC codes — the activity codes you select shape how banks and HMRC categorise you. Pick accurately; vague choices flag risk.

The certificate of incorporation usually arrives within 24 hours. That is the easy part.

The PSC register, properly understood

The PSC register is the UK's beneficial ownership disclosure system. Every company must identify and file details of any person who, directly or indirectly:

• holds more than 25% of the shares,
• holds more than 25% of the voting rights,
• has the right to appoint or remove a majority of directors, or
• otherwise exercises significant influence or control.

For overseas founders, two patterns cause repeated trouble. The first is holding shares through a foreign holding company without tracing control up to the ultimate natural person — the PSC register asks who ultimately controls the company, not just who appears on the share register. The second is informal nominee arrangements that are never disclosed; these are not only non-compliant but make later bank onboarding nearly impossible, because banks run the PSC register against their own beneficial ownership checks and notice the gap immediately.

Keep the PSC register accurate, keep it current, and keep the supporting evidence (passports, proof of address, ownership chain diagrams) in a folder you can hand to a bank in one email.

Registered office, service address and the post problem

A UK registered office is a legal address, not just a postal one. HMRC, Companies House and any party serving legal proceedings will write to it. If post is missed, the consequences range from automatic penalties to default judgments entered against the company without its knowledge.

Three practical points:

• The registered office and the director's service address can be the same or different. Most overseas founders use a professional service address for both, to keep residential addresses off the public register.
• Some virtual office providers do not forward statutory post in a usable timeframe. Ask specifically how HMRC and court correspondence is handled, not just general mail.
• If you change the registered office, file the change immediately. A stale address is the single most common cause of struck-off companies in the overseas-founder population.

VAT, banking and getting to the first invoice

Two operational questions decide whether the company can actually trade.

UK VAT registration. A UK company must register for VAT once its taxable turnover exceeds the current HMRC threshold, but many founders register voluntarily earlier — either because their customers are UK businesses who expect a VAT invoice, or because they want to reclaim VAT on UK costs. Voluntary registration is straightforward but commits you to quarterly filings under Making Tax Digital. If your customers are overseas and your costs are minimal, waiting until you approach the threshold is often the calmer choice.

Banking. This is where overseas founders lose the most time. UK high-street banks generally want at least one UK-resident director, a clear business rationale and verifiable proof of address for all PSCs. Fintech alternatives (Wise, Revolut Business, Airwallex and others) onboard non-resident founders more readily and are sufficient for invoicing, receiving payments and paying suppliers. Many founders open a fintech account first to begin trading, then add a traditional bank account once UK operations justify it.

The realistic sequence from incorporation to first invoice, assuming documents are clean, is roughly: incorporation in one to two days, registered office and PSC filings same week, fintech bank account in one to three weeks, VAT registration (if needed) in two to eight weeks, first compliant invoice issued shortly after the bank account is live.

FAQ

Do I need a UK-resident director to incorporate? No. Companies House does not require UK residency for directors. However, a fully non-resident board makes UK high-street bank account opening significantly harder, and some payment processors apply enhanced due diligence.

Can I use my accountant's address as the registered office? Usually yes, if they offer that service and have agreed to handle statutory post promptly. Confirm in writing that HMRC and court correspondence will be forwarded the same day it is received, not batched weekly.

Should I register for VAT immediately on incorporation? Only if your customers expect VAT invoices or you have material UK input VAT to reclaim. Otherwise, monitor turnover against the HMRC threshold and register when you approach it — early voluntary registration commits you to ongoing Making Tax Digital filings.
