Electrical Work Invoice Template - UK

If you're registered for VAT, you must show the VAT amount separately on your electrical invoice. UK invoices above £90,000 annually require VAT registration. Display VAT as a separate line item calculated at 20% of your service charges. If below the threshold, you can choose to register voluntarily or exclude VAT entirely—be clear which approach you use on invoices. Include your VAT number prominently if registered.

An EICR invoice must clearly identify the property, inspection date, and test reference number. Include the BS 7671:2018 standard certification and any remedial codes found (C1, C2, C3). Add the inspection frequency recommendation (usually every 5 years for rental properties). This documentation is mandatory proof for landlords meeting English, Scottish, and Welsh electrical safety regulations. Always specify whether the installation passed, failed, or requires further investigation.

Separating services shows clients exactly what they're paying for—socket installation costs differently from testing or safety inspection. Different tasks carry different expertise and time investment, so lumping them together obscures actual value. Itemized invoices are easier to approve through property management systems or tenant reimbursement schemes. Transparency builds trust and reduces payment disputes. This approach also simplifies your own cost tracking and helps identify which services generate the most margin.

Yes, separate call-out or emergency charges are standard practice in UK electrical contracting. Show this as a distinct line item, clearly labelled 'Emergency Call-Out Fee' or similar. Many electricians charge a base call-out fee (typically £50–100) plus hourly rates for work performed. Specify your call-out terms upfront in your standard rates or initial communication. This protects you financially for out-of-hours work while being transparent to customers about what they're paying for at each stage.

List PAT testing as a single line item with the quantity representing the number of appliances tested. For example: 'PAT Testing – Portable Appliances: Quantity 15 @ £8 each = £120.' This clarity shows clients they're paying per device, which is industry standard. Include the testing date or date range if the invoice covers a specific inspection period. Provide a brief summary of results (all passed, or note any failed items requiring remediation) to demonstrate thorough documentation and professional compliance.

Yes, referencing standards like BS 7671:2018 (18th Edition) strengthens your professional credibility. When invoicing for work that must meet these standards—such as consumer unit replacement or installation work—note compliance. Include phrases like 'Completed to BS 7671:2018 requirements' or reference relevant industry certifications (NICEIC, ELECSA, etc.). This reassures clients and insurers that work meets current electrical safety regulations. For inspection work, always cite the relevant standard to prove your work is current and compliant.

Issue separate invoices for each stage: an initial deposit invoice, progress invoices as work milestones complete, and a final invoice for remaining balance plus any additional work. Clearly label each invoice with its purpose—'Deposit Invoice,' 'Progress Invoice – Stage 1,' 'Final Invoice.' Specify what work the deposit covers and when payment is due. Outline the remaining scope for subsequent invoices so clients understand the full financial picture. This method protects cash flow, maintains transparency, and creates clear audit trails for both parties.

Commercial electrical contracts typically work on 30-day payment terms with deposit requirements, reflecting larger project values and corporate purchasing procedures. Domestic customers often expect payment on completion or within 7–14 days. For commercial work, requesting 25–50% upfront protects against project abandonment or client financial issues. Domestic work may require full or substantial payment upon completion due to the project's smaller scale. Clearly state your terms in writing before starting work to avoid disputes and align expectations with industry standards for your customer type.
