UK Electrician Invoice Template: EICR Certificates, Part P, and VAT
What every UK electrician invoice should include: EICR certificate line items, Part P notifiable work, and VAT considerations.
EICR certificates are an invoice line item, not a freebie
Many UK electricians include EICR (Electrical Installation Condition Report) certificates as a 'free' add-on to their invoice. This is a mistake — EICRs are a regulated professional service that requires specific competence, calibrated test equipment, and insurance. Charge for it explicitly as a line item, typically £100-200 for a domestic 1-2 bed property.
EICRs also have a defined scope per BS 7671 — the line item on your invoice should specify the inspection scope (e.g., 'EICR — 1 bed flat, 8 circuits inspected, sample of 10% accessible connections'). Vague descriptions invite disputes.
Open the electrician generatorPart P notifiable work
Part P of the Building Regulations requires that certain electrical work in domestic properties (new circuits, consumer unit replacements, work in special locations like bathrooms and outdoors) is either carried out by a registered competent person (NICEIC, NAPIT, ELECSA) or notified to building control before work begins.
If you are a Part P registered electrician, the building control notification fee is included in your work — your invoice can show it as a separate line item ('Part P notification fee: £X') or bundled into the total. Either way, the invoice should reference Part P compliance where applicable.
Materials markup and CIS
UK electricians typically markup materials 15-30% above wholesale. Show the markup explicitly on the invoice — 'Materials cost: £120 + 25% markup = £150' — both for client transparency and for CIS contractor deductions, which calculate withholding on the gross invoice amount before your markup.
If you subcontract to a VAT-registered contractor, the reverse charge under CIS may apply to your labour portion. The contractor's invoice from you should be at 0% VAT with the reverse charge note; your materials markup portion may still attract normal VAT rules depending on the supply structure.
