The Electrical certificate (NICEIC / NAPIT) — what it proves and what to do without one

The short answer: certificates turn "I think the work was bad" into "the work skipped its legal compliance step". Check the official register for the tradesperson, order replacements where possible, and treat a missing certificate as evidence in your dispute.

Notifiable electrical work (new circuits, bathroom/kitchen electrics, consumer-unit changes) needs certification by a registered electrician (NICEIC, NAPIT, or via scheme membership searchable through TrustMark). The certificate names the tests done. Missing certification on notifiable work = compliance evidence gap in your favour.

In a dispute

Attach certificates (or note their absence) in your letter before action and witness statement. At sale time, missing certificates cost real money — that diminution is claimable: schedule of loss.
