Free electrician invoice template (UK)
Built for UK electricians: itemise testing, labour and materials, add your VAT if you're registered, and note the certificate reference at the bottom.
Electrical work almost always comes with paperwork the customer needs to keep, so it helps if the invoice references the certificate as well as the price. List testing, labour and the consumer unit or accessories separately, and note the BS 7671 edition you worked to. Landlords and letting agents in particular will file this against the property.
It's pre-filled with typical electrical lines — change anything you like, add VAT if you're registered, then download the PDF. Free, unlimited, and no card required.
