How to Generate a Job Completion Report for a Client

Your Client Needs More Than a Verbal Sign-Off
When an electrician finishes a job, the work is visible: new sockets flush in the wall, a rewired consumer unit, updated lighting circuits. But a verbal "all done" doesn't protect you and it doesn't give the client anything to refer back to.
A job completion report changes that. It documents what was installed, the condition of the existing installation, test results, and the handover state. It's your evidence that the work was completed to spec, that the installation was tested, and that the client received everything they paid for.
For commercial clients, a proper completion report is often a contractual requirement. For domestic clients, it's an unexpected professional touch that generates referrals.
What a Job Completion Report Contains
A completion report doesn't need to be a formal certificate — unless the work requires one (notifiable electrical work in the UK requires an Electrical Installation Certificate, for example). For most jobs, a clear PDF with structured sections is enough.
Essential sections:
1. Job reference and client details
- Job reference number, date, property address
- Client name and contact details
- Brief description of the work scope ("Installation of new 10-way consumer unit, 7 new sockets, replacement of pendant light fittings throughout ground floor")
2. Pre-work condition
- Photos of the existing installation before you touched it
- Any pre-existing issues noted: damaged cables, overloaded circuits, out-of-spec components you were not instructed to fix
- Note the condition of the earthing system, bonding, and main fuse
3. Work carried out
- Itemised list of each task completed
- Materials installed, including brand and specification for major components (consumer unit, MCBs, RCDs, cable type and rating)
- Cable routes — briefly described for anything concealed in walls or ceiling voids
4. Test results
- Continuity readings on ring final circuits
- Insulation resistance results
- RCD test times
- Relevant Zs measurements for the circuits covered
5. Completion photos
- Consumer unit photo showing MCB labelling and any test stickers
- Each new socket and switch plate
- Any areas patched after surface wiring or chasing
6. Sign-off statement
- Your name, company, and qualification number (NICEIC, NAPIT, ELECSA, or equivalent)
- A brief statement confirming the installation has been tested and left in a satisfactory condition
- Whether PART P notification was submitted (if applicable)
How to Generate the Report Quickly
The mistake most electricians make is waiting until the job is finished to think about the report. By then, the pre-work photos are on your phone mixed in with everything else, the test results are scrawled in a notepad, and the materials list is in your head.
Generate as you go:
- Before you start: Take a photo of the consumer unit, the main incoming supply, and anything notable about the existing installation. Note it in the job record.
- During work: Photograph cable routes before they're concealed. Photograph each new installation as you complete it.
- After testing: Record test results directly into the job — ZS values, insulation resistance, RCD trip times.
- At completion: Take a clean consumer unit photo with all labels visible. Photograph each new circuit termination.
With photos and notes collected through the job, generating the final report takes under 2 minutes. You're not writing from memory — you're compiling what you already captured.
JobDone is built for exactly this. You take photos and add notes on site, then generate and send the PDF report before you leave.
When to Send the Completion Report
Send it before you submit the invoice, or with the invoice. Never after.
A client who receives a completion report before or with their invoice has:
- A clear record of what was done
- Evidence the installation was tested
- A professional document they can show their insurance company or mortgage lender if ever needed
A client who receives only an invoice is already in a frame of mind where they're looking for reasons to query it.
The Difference Between a Report and a Certificate
These are not the same thing.
A completion report is a document you create to show the client what was done. It's your professional record. It's not a statutory requirement, but it's good practice.
An Electrical Installation Certificate (EIC) or Minor Electrical Installation Works Certificate (MEIWC) is a statutory document required for notifiable work under Part P (UK). Generating a completion report does not replace the obligation to issue these certificates where required.
Where an EIC or MEIWC is required, include a copy of it in your completion report package. The completion report provides the photographic context; the certificate provides the statutory sign-off.
Completion Reports Build Your Reputation
Most electricians on domestic jobs send an invoice and nothing else. The electricians who send a professional completion report stand out immediately.
Clients remember the ones who were organised. When their neighbour asks "do you know a good electrician?", the reply comes with "and he sends you a proper report when the job's done."
