What an invoice does not prove

How we work

Certificates, codes and honest reports

Electrical work in a home ends properly with paperwork: an Electrical Installation Certificate with the test results, and for notifiable work a building regulations compliance certificate. Years later, that paperwork is what a buyer's solicitor asks for and what an insurer wants after a fire. An invoice records that money changed hands and nothing else.

EICR coding is where honesty costs money. A C1 or C2 means danger or potential danger, and a report carrying one cannot be marked satisfactory — however badly a tenancy needs to start on Monday. Electricians who soften codes to avoid remedial work are handing the landlord a document that will not survive scrutiny.

And a tripping breaker is information, not an inconvenience. It is a protective device operating, so the useful response is testing to find the fault rather than replacing the device. Swapping it removes the protection and leaves whatever caused it still in the wall.
