Texas requires this on the first page of every proposal, invoice or contract for plumbing services, written or electronic, in 12-point type or larger:
The rule counts estimates, service and billing invoices and receipts as proposals, invoices or contracts. The Board’s consumer page gives its phone number as (512) 936-5200.
This template prints notes smaller than 12 point, so on its own it does not meet the Texas rule yet. For Texas plumbing work, add the block in 12-point type to the first page before you send it.

California requires your license number on all contracts, subcontracts and bids, and CSLB treats a proposal as advertising, which needs it too. C-36 plumbing contractors also show the business name, address and license number on each side of every commercially registered vehicle, in letters at least 1.5 inches high.
Add your license number as the last line of your address under From, and it prints under your business name on every invoice.

A business doing gas work within the scope of the Gas Safety (Installation and Use) Regulations 1998 must be on the Gas Safe Register.
The register’s policy says a business does gas work only under its registered trading name, and that name belongs on its invoices, headed paper, adverts, website and van stickers. Its work records, kept for at least six years, show the engineer’s name, the Gas Safe registration number, the work done with its safety checks, the date and the address.

Put your Gas Safe registration number on every quote and invoice for gas work, with the appliance make and model and the certificate you issued, for example the Building Regulations compliance certificate for a new boiler. Customers check the number.
For work that is not gas, such as a radiator swap, the standard UK invoice rules apply, with VAT only once you are VAT registered.
Rules checked against the official sources linked above on October 19, 2026. Example prices are illustrative. This is general guidance, not legal or tax advice.
On the first page, in 12-point type or larger: the Responsible Master Plumber’s name and license number, the words “regulated by the Texas State Board of Plumbing Examiners”, and the Board’s mailing address, phone number and website.
