Miss a required field and your invoice may not be valid. Here's everything HM Revenue & Customs expects on it.

An invoice that's missing the right fields can cause payment delays — or, if it's meant to be a VAT invoice, it might not even be valid. Here's what HM Revenue & Customs expects in United Kingdom.

What a compliant invoice needs

Your business name and VAT Registration Number (VAT No.).

The word "Invoice" (or "VAT Invoice" where you're registered).

A unique invoice number and the date issued.

A clear description of the work and materials.

VAT shown separately (20%), with the total in GBP.

The client's name and address.

Make it easy to get paid

**The faster you make payment, the faster the money lands.** Put your payment details and due date where the client can't miss them, and number every invoice sequentially so your records stay clean at tax time.

Send it while the job's fresh

The best time to invoice is the moment the work's done. UteQuote builds a HMRC-compliant invoice on-site by voice, with your VAT No. and VAT already handled.

Frequently asked

Do I need to charge VAT?

Only if you're registered for VAT. Registration is required once your turnover reaches £90,000 in United Kingdom. If you are registered, show VAT separately on every invoice.

Do I need a VAT No. to invoice?

If you're running a business in United Kingdom you should have a VAT Registration Number (VAT No.). It makes you look legitimate and keeps your invoices compliant.
