What Should a Tradesperson Invoice Include? 2026
A professional invoice does two things – it tells your customer exactly what they owe, and it protects you legally if anything goes wrong. Here’s everything a UK tradesperson invoice must include in 2026, plus a quick checklist to run through before you send.
The Legal Requirements – What Must Be on Every Invoice
The word “Invoice”
Clearly at the top of the document. This distinguishes it from a quote or a receipt.
A unique invoice number
Every invoice must have its own reference number – essential for your records and Self Assessment return. Keep it simple and sequential.
Examples
INV-001, INV-002, INV-003 – or with year: 2026-001, 2026-002. Never use the same number twice.
The date of the invoice
The date it was issued – this is the starting point for your payment terms.
Your business details
- Your full name or business name
- Your business address or correspondence address
- Your contact details – phone number and email
- If a limited company: company registration number and registered office address
Your customer’s details
Full name or business name and their address. Important if you ever need to chase payment formally.
A clear description of the work
One of the most important sections – and one of the most commonly done badly. Don’t just write “plumbing work.” Be specific.
Good example
Remove existing boiler and dispose of responsibly · Supply and fit new Worcester Bosch 30i combi boiler · Commission and test · All pipework and fittings included
A clear description prevents disputes, builds trust, and gives the customer confidence they’re paying for exactly what was agreed.
The amount charged
Where possible, split out materials cost, labour cost, and any call-out fees separately. This transparency builds trust and makes it easier to justify your price if questioned.
The total amount due – clearly highlighted
Bold it, make it larger, put it in a box – whatever it takes to make it impossible to miss at a glance.
Your payment details
- Bank name, account name, sort code, account number
- If you accept card payments or PayPal – include those details too
- The easier you make it to pay, the faster you get paid
Your payment terms
Always state when payment is due – e.g. “Payment due within 14 days of invoice date.” Without a due date your customer has no deadline and late payments become much harder to chase legally.
If You Are VAT Registered
Additional requirements for VAT-registered tradespeople
- Your VAT registration number
- The VAT rate applied to each item (usually 20%)
- The VAT amount charged
- The total amount excluding VAT
- The total amount including VAT
If you’re not yet VAT registered – the threshold is £90,000 turnover in a 12-month period – you don’t need to include any VAT information and should not charge VAT.
Optional Extras That Help You Get Paid Faster
Your logo
Makes you look established and professional. Even a simple one at the top makes a real difference to first impressions.
Late payment clause
A note that late invoices may be subject to statutory interest under the Late Payment of Commercial Debts Act. Encourages on-time payment without being aggressive.
A thank you note
A short line thanking the customer costs nothing. Customers who feel appreciated pay faster and come back more often.
Terms and conditions
For larger jobs, a brief summary of your T&Cs or a link to them on your website – protects you if scope or payment is disputed.

Every UK tradesperson invoice must include: the word “Invoice” clearly at the top; a unique sequential invoice number; the date the invoice was issued; your full name or business name and address; the customer’s name and address; a clear description of the work carried out; the amount charged (ideally split between labour and materials); the total amount due prominently displayed; your bank details (sort code and account number); and your payment terms with a specific due date. If you are VAT registered, you must also include your VAT registration number, the VAT rate, the VAT amount, and totals both including and excluding VAT.
Yes – wherever possible. Separating labour costs from materials costs on your invoice builds customer trust by showing exactly what they’re paying for, makes it easier to justify your price if questioned, creates cleaner records for your own bookkeeping, and is particularly important for VAT-registered tradespeople where different rates may apply to different elements. Even if you charge a single fixed price for a job, breaking it down on the invoice into labour and materials is considered best practice and helps avoid disputes.
Only if you are VAT registered. The VAT registration threshold is £90,000 taxable turnover in a rolling 12-month period. If you are below this threshold and not voluntarily registered, you must NOT charge VAT on your invoices and do not need to include any VAT information. If you are VAT registered, you must include your VAT registration number, the VAT rate applied (usually 20% standard rate), the VAT amount, and the total both including and excluding VAT. Charging VAT when you are not registered is illegal.
Always include a specific due date rather than just “payment due on receipt” (which is legally vague). Common terms for UK tradespeople: 14 days from invoice date for most domestic jobs; 30 days for larger commercial or construction contracts (the default under UK law for business-to-business transactions if nothing is agreed). For smaller jobs you can specify “payment on completion.” You can also add a late payment clause noting that overdue invoices may be subject to statutory interest under the Late Payment of Commercial Debts Act – this encourages prompt payment without being aggressive.
Use a simple sequential numbering system starting from 001 (e.g. INV-001, INV-002, INV-003) or include the year for extra clarity (e.g. 2026-001, 2026-002). The critical rule is that every invoice must have a unique number – never reuse or skip a number. Sequential numbering makes it easy to track which invoices have been paid and makes your records look professional and organised to HMRC if your accounts are ever reviewed. Invoicing software handles numbering automatically, eliminating the risk of duplicates.
The Bottom Line
A proper invoice isn’t just about getting paid – it’s about looking professional, protecting yourself legally, and building a reputation as a tradesperson who runs a tight operation. Get into the habit of sending complete, professional invoices on the same day every job is done and you’ll have fewer disputes, faster payments, and happier customers.
