Preparing an electrical inspection: reason, scope and documents
A periodic inspection of a building installation is a different commission from independent acceptance after new work or checking previously reported defects. The reason, affected areas and available records help identify the appropriate inspector and a comparable scope.
Give the reason without having to choose the inspection procedure
A notice from the network operator, a planned sale, recent electrical work or an existing defect report may prompt the enquiry. Give the actual reason and any known deadline. The professional clarifies the procedure appropriate to the installation.
The installer's final inspection, independent acceptance inspection and periodic inspection have different roles. A voluntary condition assessment is also possible but does not automatically replace a required inspection. Testing individual electrical appliances is a separate commission.
| Reason | Clarify in the quote |
|---|---|
| Periodic notice | Affected installation, available letter and deadline. |
| Change of ownership | Sale context and known previous inspection records. |
| New or altered installation | Completed work and inspections already performed. |
| Follow-up inspection | Defect report, known rectification and requested completion. |
| Initial advice | Open question and clarification before an inspection. |
Distinguish dwellings, common areas and additional installations
An apartment, a detached house and a building with common areas have different inspection scopes. For several dwellings, the exact count and the boundary between individual units and the communal installation matter.
Describe basements, garages, plant rooms and other affected spaces. Photovoltaics, charging stations, batteries and other particular installations may require additional scope and appropriate inspection responsibilities. An apartment inspection does not automatically include them.
For mixed use or several sites, start by describing the units and areas. You do not need to take measurements, count protective devices or establish a technical classification yourself.
Use available records and clarify what is missing
A notice, earlier safety certificate, inspection protocols and records of recent work help establish the context. Mention what is available. Missing papers are a matter to discuss with the professional and do not call for your own electrical tests.
The construction year and known alterations provide context but do not establish the condition or inspection interval on their own. The professional assesses the installation and the records needed for this commission.
A safety certificate records the result of the relevant inspection. It is not a blanket guarantee covering every appliance or all future alterations. Specify which documents and any onward submission are included.
Assign inspection and defect rectification appropriately
For periodic inspections and required independent acceptance inspections, independence from design and execution is essential. Clarify appropriate inspection authorisation and any earlier involvement in the installation.
Identified defects are documented. Their rectification is a separate commission for a contractor with the appropriate installation authorisation. An independent inspection should not be assumed to include corrections by the same party.
Whether another inspection is needed after rectification and when documentation can be completed depend on the findings and procedure. A quote for a safety certificate does not promise a defect-free result regardless of the installation's condition.
Arrange access and possible interruptions
Locked plant rooms, occupied rental apartments and operating hours require coordination. Arrange access to the affected rooms and distribution boards without opening covers or taking measurements yourself.
Measurements may require power interruptions. Mention operations or sensitive systems whose shutdown needs particular coordination. The responsible people agree the approach before the appointment.
A shared appointment is useful only when the necessary areas are actually accessible. Inaccessible parts and additional visits should be addressed clearly in the quote.
Compare inspection, documentation and follow-up costs separately
Installation scope and complexity, the number of units and particular systems affect inspection work. One apartment and an entire building with common areas are not equivalent price items.
Check whether travel, administration, measurements, agreed protocols, the safety certificate and submission are included. Defect reports and follow-up inspection may be included or charged separately. Actual rectification is not automatically part of the inspection quote.
Ask for unresolved assumptions and additional services to be identified. Extra work and its costs should be explained and approved before commissioning. Compare VAT, waiting time and conditions for further appointments too.
| Cost item | Comparison point |
|---|---|
| Initial inspection | Precisely affected units, common areas and additional installations. |
| Documentation | Protocols, report, certificate and agreed submission. |
| Identified defects | Reporting and separately commissioned installation repairs. |
| Follow-up inspection | Required scope, further travel and included appointments. |
| Organisation | Access, waiting time, additional charges and VAT. |
Useful details for the enquiry
Describe what you know and the result you need. Technical uncertainties can be clarified with the inspector.
- Reason. Mention a notice, sale, recent work, follow-up or need for advice.
- Scope. Describe the building, units, common areas and known particular installations.
- Records. Mention available letters, earlier reports and known rectification.
- Organisation. Give the location, access, deadline and interruptions needing coordination.
From the commission to documented completion
A clear sequence helps arrange the inspection and any further steps with the appropriate parties.
- Define the commission. Clarify the reason, installation and expected records.
- Compare quotes. Compare the same inspection scope, additional charges and follow-up.
- Prepare the appointment. Coordinate access and necessary interruptions.
- Address findings. Discuss the defect report and commission rectification separately.
- Clarify completion. Review follow-up inspection, documents and agreed submission.
Frequently asked questions
Do I need to know the inspection interval?
No. Give the reason, known use and available notices. The appropriate professional clarifies the procedure and installation requirements. You do not need to select a technical standard class.
Does every house sale need the same inspection?
No. The type of installation and time since the last inspection matter. Have the specific change-of-ownership case assessed using available records.
Are common areas automatically included for an apartment?
Not automatically. Stairwells, garages, heating rooms and other communal installations must be expressly defined.
Can the same company perform independent inspection and repairs?
For periodic and required independent inspections, the roles need to be distinguished. The inspector and an appropriately authorised installation contractor coordinate reporting, rectification and any follow-up.
Can inspection take place without power interruption?
That cannot be promised generally. Necessary measurements may involve interruptions. Operations and sensitive systems therefore need early appointment coordination.
Will I receive the safety certificate immediately?
Not regardless of the outcome. Identified defects may need rectification and further assessment. Agree the documents, follow-up and submission for the actual commission.
