Invoice template for trades: what to include and a free invoice maker

An invoice with a missing date, no bank details or VAT done wrong gets paid late or queried. This guide covers what a UK invoice has to show, how VAT, the construction reverse charge and CIS go on it, and a free maker that writes the invoice, checks it, and prints it to PDF.

Updated 28 October 2026 · UK · Checked against gov.uk, HMRC VAT Notice 700 and legislation.gov.uk · General information, not tax or legal advice

The short answer: every UK invoice needs a unique invoice number, your business name, address and contact details, the customer's name and address, a clear description of the work, the date the work was done and the invoice date, the amounts, VAT if you charge it, and the total owed (gov.uk). Add a due date and how to pay, because those are what get it paid.

Sole traders using a business name also show their own name. Limited companies use the full registered name. VAT-registered trades billing a CIS contractor usually use the reverse charge, and CIS comes off the labour only.

Print it or save it as a PDF from the print screen, or copy it into Word or Google Docs. Everything stays in your browser. Nothing you type is sent anywhere.

You

The customer and the job

VAT and payment

The checker spots common problems; it can't see your job or your VAT position. Read the invoice through and check the figures before you send it. If you're unsure about VAT or CIS on a job, ask your accountant or HMRC.

What a UK invoice must include

This is gov.uk's list, with what it means for a trades job. If you're VAT registered there's more (see VAT invoices).

Must includeOn a trades invoice
A unique identification numberINV-0001, INV-0002… in order. Never reuse one, even for a cancelled invoice.
Your name, address and contact detailsBusiness name, address, phone and email. Add your Gas Safe or NICEIC number if it's relevant to the job; customers like seeing it.
The customer's name and addressThe person or company paying. If the job was somewhere else (a rental flat, a building site plot), add the job address too.
A clear description of what you're charging for"Replaced two bedroom radiators and fitted TRVs", not "work done". Quote your quote number so they can match it.
The date the work was done (supply date)The day you finished, or the period for a longer job ("work 19–30 October 2026").
The date of the invoiceThe day you send it. Send it the day you finish if you can.
The amounts chargedA line each for labour, materials and anything else (skip, hire, call-out). Quantities help: "2 x £98.20".
VAT, if applicableOnly if you're registered. If not, say so.
The total amount owedAfter any deposit already paid or CIS deduction, so they know exactly what to send.

Not on gov.uk's list, but they decide how fast you're paid: a due date ("Payment due by 4 November 2026"), how to pay (bank details with the invoice number as the reference), and a name and number to call with questions. If no payment date was agreed, the customer must pay within 30 days of getting the invoice or the work (gov.uk).

Sole trader, partnership or limited company

You areExtra on the invoice
Sole trader using your own nameNothing extra. "Robin Hale, Plumbing and Heating" is fine.
Sole trader using a business nameYour own name too, and an address where legal documents can reach you (gov.uk). "Robin Hale trading as Hale Plumbing & Heating" does both jobs.
Limited companyThe full registered name as on the certificate of incorporation ("Hale Plumbing Ltd", not "Hale Plumbing"). Companies must also show the company number, where it's registered and the registered office on business letters and order forms (2015 regulations, reg 25), so put them in the invoice footer. If you name one director, you must name them all.

VAT invoices: what changes once you're registered

If you're not VAT registered, don't add VAT, and write "Not VAT registered" on the invoice so nobody wonders. You must register if your taxable turnover goes over £90,000 in a rolling 12 months (gov.uk).

Once you are registered, you must give a VAT invoice to VAT-registered customers, and in practice to anyone who asks. HMRC's list (VAT Notice 700, 16.3) adds to the basics:

For a job of £250 or less including VAT you can give a simpler VAT invoice if the customer agrees (16.6.1). Send VAT invoices within 30 days of the tax point (16.2.3). Most domestic trades work is at the standard 20%. Some energy-saving installations in homes are zero-rated until 31 March 2027 (notice 708/6), so check the notice before you charge VAT on a heat pump, insulation or solar job.

The construction reverse charge (VAT-registered subcontractors)

If you're VAT registered and do construction work for a contractor who is VAT and CIS registered, the domestic reverse charge usually applies: you don't charge VAT, and the contractor pays it to HMRC instead. It covers most building work, including installing heating, plumbing, electrics and drainage, and painting and decorating.

It doesn't apply to homeowners or other customers who aren't VAT and CIS registered, or to an end user (a business that isn't selling the work on, such as a shop having its own premises refitted) who has told you so in writing. Then you charge VAT as normal.

On the invoice, HMRC's technical guide says to:

The invoice maker does all three when you pick "Reverse charge", and warns if you pick it for a homeowner.

CIS deductions on an invoice

Under the Construction Industry Scheme, the contractor takes a deduction from what they pay you and sends it to HMRC as an advance on your tax and National Insurance (gov.uk):

Your CIS statusDeduction
Registered for CIS and verified by the contractor20%
Not registered (or they can't verify you)30%
Gross payment status0% (you pay your own tax)

The deduction comes off labour only. It isn't taken from VAT, materials you paid for, plant hired for the job, or consumables. So list materials as separate lines and keep the receipts: the contractor can ask for them, and will estimate the materials if you can't show them.

A worked example: a VAT-registered plumber, registered for CIS, does three days' first fix for a contractor at £220 a day and supplied £184.50 of copper and fittings.

The contractor pays £712.50 and must give you a payment and deduction statement within 14 days of the end of each tax month. Keep every statement: the £132 counts towards your tax and National Insurance on your Self Assessment return (your bookkeeper or accountant will want them).

Plain invoice template to copy

If you'd rather fill in a template in Word, Google Docs or your notes app, copy this. Delete the lines that don't apply (VAT, CIS, company details).

Using ChatGPT, Gemini or Claude for invoices

AI is handy for turning a job sheet or a voice note into tidy invoice lines. It's risky with numbers: it can add up wrong, invent a VAT figure, or apply the reverse charge to a homeowner. So give it your figures, tell it not to work out tax itself, and check the totals (or paste the lines into the maker above).

Leave the customer's address and phone out of the chat; add them in the maker or your template.

Quote it, invoice it, chase it. Our free Trades Skills for ChatGPT, Gemini and Claude include quote-builder (rough notes into a clear quote, so the invoice matches what was agreed) and payment-chaser (the right reminder for an overdue invoice, from friendly to letter before action, with UK late-payment interest worked out).

Trades Skills Pro adds change-order (price extra work mid-job so it's on the invoice, not an argument), customer-terms (plain-English terms with your payment terms), job-handover, complaint-handler and price-rise.

FAQ

What must an invoice include in the UK?

A unique invoice number, your business name, address and contact details, the customer's name and address, a clear description of what you're charging for, the date the work was done, the invoice date, the amounts, VAT if you charge it, and the total owed. Sole traders using a business name also show their own name; limited companies show the full registered name.

Do I need to put VAT on my invoice if I'm not VAT registered?

No. You can't charge VAT unless you're registered. Say "Not VAT registered" on the invoice so the customer doesn't wonder whether it'll be added later. You must register once your taxable turnover passes £90,000 in a rolling 12 months.

What do I write on an invoice for the construction reverse charge?

Show everything a VAT invoice needs, don't add the VAT to the amount charged, and add a note such as "Reverse charge: customer to pay the VAT to HMRC" or "VAT Act 1994 Section 55A applies", with the amount of VAT due under the reverse charge. It only applies when your customer is VAT and CIS registered and isn't an end user.

How do I show CIS on an invoice?

Split labour and materials, then show the deduction on labour only: 20% if you're registered for CIS, 30% if not, 0% with gross payment status. The contractor takes it off when they pay you and gives you a monthly statement.

When does a customer have to pay an invoice?

By the date you agreed. If no date was agreed, gov.uk says the customer must pay within 30 days of getting the invoice or the work. Put a due date and how to pay on every invoice.

What's the difference between an invoice and a receipt?

An invoice asks for payment; a receipt confirms you've been paid. If a customer pays on the day, give them a receipt with the same details, marked "Paid in full" with the date and how they paid.

I made a mistake on an invoice. Can I just change it?

Not once it's been sent. Issue a credit note that cancels all or part of it, then a new invoice with a new number. That keeps your numbering and your records straight.
