Itemising labour, materials and the diagnostic call
Electrical work lives or dies on a clear breakdown, because customers rarely know what a fault-find actually involves. Start with your diagnostic or call-out fee on its own line — the time to trace an intermittent circuit is real work whether or not a repair follows. Bill labour either hourly or as a flat-rate price per task, such as a fixed figure to add a spur or change a consumer unit. Then list every material: the breakers, the cable by the metre, the back boxes, the accessories. Electricians who lump cable and time together get pushed on price; those who show a customer the individual MCBs and the run of twin-and-earth get paid without the haggle.
Permits, inspections and certification lines
Notifiable electrical work often needs a permit, a building-control notification or a third-party inspection, and those carry cost you should pass on transparently. Add a line for the permit or notification fee, and a separate one for any certificate you issue — an installation certificate or condition report is billable work and evidence the job was done to standard. If a job requires periodic inspection or testing, itemise the test time distinctly from the installation labour. Emergency and after-hours work gets its own premium rate line, the same as any trade. Every one of these lines is editable in the template, so you can keep a saved version with your standard certification and permit wording already filled in.
Warranty, tax and payment terms
State your guarantee on the invoice — commonly a workmanship warranty on your labour, with manufacturer cover on the parts and accessories. Reference the certificate number if you issued one, so the paperwork all ties together. Where you are registered for VAT or sales tax, show net, tax and gross separately with your registration number; if not registered, say so briefly so no one expects a tax split. Give a firm due date, your payment details and a purchase-order field for commercial clients and letting agents who will not pay without one. Export to PDF so the figures and your certification note cannot be altered in transit, or to Word if a client needs to countersign.
