Electrical inspection cost in Luxembourg (2026)

All values incl. TVA 17 %. All of these are voluntary checks by an approved electrician; none is a legal requirement for a private dwelling.

Included in a standard safety check:

• Visual inspection of the consumer unit (tableau électrique), labelling legibility, RCD (30 mA) protection on required circuits
• Continuity test of all protective conductors
• Insulation resistance test per circuit (500 V megger)
• RCD trip-time test at rated current and 5× rated current
• Earth-loop impedance test from accessible outlets
• Verification of correct polarity on accessible outlets
• Visual check of exposed wiring for age, damage, over-temperature indicators
• Written report listing findings with priority ratings (critical / important / cosmetic)

Not included unless requested:

• Infrared thermal imaging of the consumer unit under load (+€120–€240)
• Dielectric test on specialised circuits
• Signal-integrity testing of data or communication cables
• Verification of emergency-lighting systems in commercial premises (separate inspection)

Luxembourg does not impose a periodic electrical inspection on private dwellings, and there is no mandatory electrical diagnostic when a home is sold or rented (unlike France's diagnostic électrique). The checks that do exist are tied to work on the installation and to the grid connection.

What the rules require:

• Work on a fixed installation is carried out by an approved electrician holding an autorisation d'établissement, following the grid operators' TAB-BT technical rules and the applicable standards
• For a new connection or a power increase, the electrician sends the grid operator (usually Creos) a signed end-of-works notice; Creos checks the installation before fitting the meter
• In Luxembourg City, a "Certificat du Service de l'Électricité" is needed for connections
• For the installation behind the meter, Creos refers owners to an approved electrician

When a voluntary check is worth it:

• After buying an older home: a check with a written report gives you a prioritised list of corrective work before you move in (€320–€650)
• Before a renovation: the electrician confirms whether the consumer unit and existing circuits can take the new loads, which shapes the renovation budget
• Warning signs: smell of burning plastic, breakers tripping repeatedly, warm switch plates, flickering lights — book a safety check (€180–€480); a 48-hour slot may add 25–40 %
• If a bank or insurer asks for an electrical report, get its requirements in writing before booking so the electrician covers exactly that

What the findings typically look like:

• An average Luxembourg apartment built 1970–1995 fails on: missing 30 mA RCD on kitchen circuit (most common), earthing continuity gap in old outlets, overloaded consumer unit with multi-taps, non-compliant bathroom zone clearances
• An average house built 1950–1980 additionally fails on: single-insulation wiring (normal for era), consumer unit in garage with no access door, earth rod not tested in 20 years
• Newer builds (post-2000) generally pass with only cosmetic findings
• Critical findings (immediate-danger classification) appear in under 5 % of inspections — usually a seriously overloaded circuit or a live-exposed junction box

For a private home in Luxembourg, the check is done by an approved electrician — there is no state inspector or certification body to book. Knowing who does what keeps you from paying for a document nobody requires.

Who does what:

• Approved electrician — holds an autorisation d'établissement for electrical installation work; carries out the work and the voluntary check, and signs the end-of-works notice sent to the grid operator for a new connection or power increase
• Grid operator (Creos in most communes) — checks a new connection or power increase before fitting the meter; for the installation behind the meter it refers owners to an approved electrician
• Luxembourg City — connections there need a "Certificat du Service de l'Électricité"
• ILR (Institut Luxembourgeois de Régulation) — regulates the grid operators; it does not inspect or certify homes

How to pick the right check:

• Buying an older home you plan to renovate: a check with a detailed written report and corrective-work list
• Home in good condition, no plans for works: a standard safety check is usually enough
• Selling or letting: no inspection is legally required; a recent report can still answer buyers' or tenants' questions
• Ongoing household: a check by an electrician every 10–15 years is good practice

Questions to ask the electrician before booking:

• "Do you hold an autorisation d'établissement for electrical installation work?" (Ask for the number)
• "What will the written report contain?" (Measurements per circuit, findings by priority, a corrective-work list)
• "What is your test-equipment calibration date?" (Should be within the last 12 months)
• "What happens if my installation has defects — do I get a list of corrective actions with cost estimates?" (Good electricians provide prioritised lists; some provide rough cost bands, most do not)

The "independent quote" principle:

• Never have the same firm that will do the corrective work also do the inspection
• The inspector's fee should be separate from any follow-up work you commission
• This eliminates the incentive to invent problems
