Limited Company Invoice Requirements: UK Rules for 2026

Quick answer: UK limited company invoice requirements are the standard invoice details (unique number, invoice and supply dates, customer details, description, amounts and total) plus the company's identity: its full registered name including Limited or Ltd, company number, registered office address and place of registration. Add a VAT number and VAT breakdown only if the company is VAT registered.

Incorporating changes how you invoice. As a sole trader you bill in your own name; as a limited company you bill as a separate legal person, and the law expects customers to be able to identify that person from your paperwork. This guide sets out the limited company invoice requirements that apply in 2026, explains what is compulsory and what is optional, and walks through a complete example you can copy into our UK invoice generator.

If you have just moved from self-employment, our guide on how to invoice as a sole trader in the UK covers the basics; this article focuses on what changes once you have a company. If you are still setting the company up, start with how to set up a limited company.

The standard invoice details every UK business needs

GOV.UK's guidance on what invoices must include applies to every business, limited or not. As of 2026, an invoice must show:

• A unique identification number (the invoice number).
• Your company name, address and contact details.
• The name and address of the customer you are invoicing.
• A clear description of what you are charging for.
• The date the goods or services were supplied (the supply date).
• The date of the invoice.
• The amount or amounts being charged.
• VAT, if applicable.
• The total amount owed.

The invoice number must be unique and should run in sequence. If you are unsure how to structure it, our article on building an invoice numbering system explains prefixes, year codes and what to do after a cancelled invoice, and the free invoice number generator creates a consistent sequence for you.

Extra limited company invoice requirements

A limited company has disclosure duties under company law that a sole trader does not. The key points GOV.UK sets out are:

Full registered company name

Use the company name exactly as it appears on the certificate of incorporation, including "Limited" or "Ltd". "Brightline Studio" is not enough if the registered name is "Brightline Studio Ltd". If you trade under a different brand, you can show the brand prominently, but the registered name must still appear, for example "Northwind Design, a trading name of Brightline Studio Ltd".

Company number, registered office and place of registration

The company's stationery and website rules require business letters, order forms and websites to show:

• The registered company number.
• The registered office address.
• Where the company is registered: England and Wales, Scotland or Northern Ireland.
• That it is a limited company, normally by using the full name with Limited or Ltd.

Invoices are almost always sent by letter or email, which counts as business correspondence, so the safe and normal practice is to print all four details on every invoice. A single footer line handles it: "Brightline Studio Ltd. Registered in England and Wales, company number 12345678. Registered office: 10 Example Street, Leeds LS1 1AA."

Directors' names: optional, but all or none

You do not have to list directors. If you choose to name one director on an invoice or letter, you must name all of them. Most small companies skip this and give a contact name instead.

Share capital: optional, and only paid-up

You may mention share capital, but if you do, it must be the paid-up amount. Few small businesses bother.

Sole trader vs limited company invoice: what changes

The table below compares the identity details on each type of invoice. If you are still deciding which structure to use, see sole trader vs limited company.

Detail	Sole trader	Limited company
Name shown	Your name, or your name plus trading name	Full registered name with Limited or Ltd
Company number	Not applicable	Shown (standard practice)
Registered office	Not applicable	Shown (standard practice)
Place of registration	Not applicable	England and Wales, Scotland or Northern Ireland
Directors' names	Not applicable	Optional, but all or none
VAT number	Only if VAT registered	Only if VAT registered
Bank account	Can be personal, ideally separate	Must be the company account
Who is owed the money	You personally	The company

The last two rows matter more than they look. Money paid to a limited company belongs to the company. If customers pay into your personal account, you create a mess in the books and, potentially, a director's loan account entry to unpick at year end.

VAT invoice requirements for a limited company

Being a company does not by itself make you VAT registered. Registration is compulsory when taxable turnover passes the threshold explained in our guide to the UK VAT registration threshold, and voluntary below it. Once registered, invoices to VAT-registered customers must be full VAT invoices. On top of the standard details, that means at least:

• Your VAT registration number.
• The time of supply (tax point), if different from the invoice date.
• A unit price and quantity for each line, the rate of VAT and the VAT amount.
• The total excluding VAT, the total VAT and the total payable.
• Wording for any reverse charge, exemption or zero rate where it applies.

Our VAT invoice guide covers full, simplified and modified VAT invoices in detail, and our separate reverse charge guide covers construction and cross-border services. If you are not VAT registered, leave VAT off entirely; showing a VAT number you do not have is a serious error.

How to create a compliant limited company invoice

1. Set up your company profile once. Enter the full registered name, trading address, email and phone. Put the company number, registered office and place of registration in the footer or notes field.
2. Add the customer's details. Use the customer's legal name. If they are also a company, use their registered name and the address their accounts team asks for.
3. Allocate the next invoice number. Keep one sequence for the company, separate from any old sole trader numbering.
4. Enter the invoice date and supply date. If the work spanned a period, state it, for example "Services 1 to 30 September 2026".
5. Describe each line clearly. Quantity, unit price and a description a stranger could understand.
6. Apply VAT only if registered. Use one rate per invoice for standard-rated work.
7. Record deposits. Use the amount paid field so the invoice shows the balance due.
8. State payment terms and bank details. Give the company bank account, a due date and your late payment position. Our guide to invoice payment terms has wording you can reuse.
9. Save a PDF and file it. Companies must keep accounting records, so store every PDF in one folder per financial year.

Worked example: a VAT-registered limited company invoice

Brightline Studio Ltd is VAT registered and builds a website for a retailer. The agreed price is 16 hours of design at £75 an hour and a fixed £1,200 development fee. The customer paid a £500 deposit when the job started.

Line	Calculation	Amount
Design, 16 hours at £75	16 x £75	£1,200.00
Development (fixed fee)	1 x £1,200	£1,200.00
Subtotal	£1,200 + £1,200	£2,400.00
VAT at 20%	£2,400 x 20%	£480.00
Total	£2,400 + £480	£2,880.00
Amount paid (deposit)		-£500.00
Balance due	£2,880 - £500	£2,380.00

The header shows "Brightline Studio Ltd", the trading address and contact details. The footer reads: "Registered in England and Wales, company number 12345678. Registered office: 10 Example Street, Leeds LS1 1AA. VAT reg no. GB 123 4567 89." Payment terms state 30 days and the company's own sort code and account number. That single invoice satisfies the general invoice rules, the company disclosure rules and the VAT invoice rules. You can reproduce it exactly in the free invoice generator using one 20% tax rate and the amount paid field.

If the company were not VAT registered, the invoice would stop at a £2,400 total, less the £500 deposit, leaving £1,900 due, with no VAT line and no VAT number.

Common limited company invoicing mistakes

• Dropping "Ltd" from the name. Branding often shortens the name; the invoice must not.
• Using the sole trader template after incorporating. Old templates carry your personal name and personal bank details, which sends money to the wrong legal person.
• Restarting numbering at 1 for each client. Numbers should be unique across the company.
• Naming one director only. If you name any director, name them all.
• Charging VAT before registration takes effect. You cannot charge VAT until you are registered; you may be able to reissue invoices once your number arrives, following HMRC's rules.
• Editing an issued invoice. To correct a sent invoice, issue a credit note and a new invoice. A credit note keeps the audit trail intact and your numbering unbroken.

Special cases: incorporation, trading names, contractors and e-invoicing

Invoicing around the date you incorporate

The switch from sole trader to company needs a clean cut-off. Work you delivered before the company existed belongs to you personally, so invoice it from your sole trader template, in your own name, and report it on your Self Assessment return. Work delivered after incorporation belongs to the company and should be invoiced by the company, with its own number sequence starting from the incorporation date. If a job straddles the date, split it into two invoices by the work done in each period rather than invoicing the whole job from one entity.

Tell clients in writing that you have incorporated, give them the company's details for their supplier records and ask them to update the payee bank account. Many accounts teams need a new supplier form before they can pay a new entity, so start that process before you send the first company invoice, or payment may be delayed by weeks.

Trading names

A company can trade under a brand that differs from its registered name. That is fine, but the registered name must still appear on the invoice so the customer knows which legal entity they are contracting with. A simple line under the logo, "Northwind Design is a trading name of Brightline Studio Ltd", plus the footer disclosures, meets the requirement without spoiling the design.

Contractors and IR35

Many limited companies are one-person contracting businesses. The invoice rules are identical, but your client may ask for extra fields such as a purchase order number, timesheet reference or agency code. If the engagement falls inside the off-payroll rules, the fee-payer deducts tax before paying you, and your invoice process changes; our guide to IR35 and contractor invoices explains how. Outside IR35, you invoice gross and the company pays Corporation Tax on its profit.

What is coming: e-invoicing in the UK

The government has announced plans to make e-invoicing mandatory for VAT invoices from April 2029. A PDF emailed to a customer will not count as an e-invoice under that regime. The required content will be similar, but delivered as structured data. Our explainer on the UK e-invoicing mandate covers the timeline and how to prepare. For now, a clear PDF invoice with all the details above is fully compliant.

Keeping invoices consistent with Companies House

Your invoices feed your accounts, your Corporation Tax return and, once a year, the information you check when filing your confirmation statement. If the registered office changes, update your invoice footer the same day you update Companies House. If you change the company name, update templates immediately, because the old name will no longer match the register. A quick quarterly review of your template catches most of these issues.

Create your limited company invoice

Meeting limited company invoice requirements is mostly a one-time setup: get the registered name, company number, registered office and place of registration into your template, add VAT details if you are registered, and every invoice after that will be compliant. Choose a professional layout such as the corporate invoice template, then build and download your invoice in the free invoice generator, no sign-up needed. No sign-up is needed, and your PDF invoice is ready to send in a few minutes.
