Electrical inspection cost in Luxembourg (2026)

All values incl. TVA 17 %.

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)

In Luxembourg, four situations trigger an electrical inspection requirement. Knowing which applies to you saves both time and money.

Trigger 1 — Pre-purchase due diligence:

• Luxembourg property sellers do not have a legal duty to provide an inspection certificate (unlike France's Diagnostic Électrique Obligatoire), but buyer-side banks increasingly require one for older properties
• Typical bank threshold: mortgage applications for buildings older than 15 years with no documented electrical refurbishment in the last 10
• Buyer orders and pays (€320 to €650); findings inform the negotiation
• If serious findings, buyer can either renegotiate price or request seller to rectify before notary signature

Trigger 2 — Post-renovation recertification:

• Any major electrical work (new consumer unit, circuit additions, structural rewiring) triggers an SREL or Aicae re-inspection
• The electrician who did the work normally arranges this; it is part of the job
• Cost: €450 to €780 passed on in the renovation invoice
• Mandatory for any work registered under the Autorisation de bâtir framework

Trigger 3 — Safety concerns or insurance request:

• Smell of burning plastic, tripping breakers repeatedly, warm switch plates, flickering lights
• Insurance companies may request an inspection certificate before renewing household policy for pre-1980 properties, or after a claim involving electrical cause
• Cost: €180 to €480 safety inspection; fast-track (48-hour turnaround) may add 25–40 %

Trigger 4 — Commercial and rental compliance:

• Commercial properties must have a periodic SREL inspection every 3 years under Luxembourg workplace safety rules (Code du travail Article L.312-4)
• Landlords renting to tenants are not legally required to provide an inspection but insurance may require it for pre-1990 buildings
• The standard workplace inspection cycle: 3 years for common industrial and commercial environments, 1 year for regulated high-risk premises (garages with fuel, wet processing, explosive atmospheres)

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

Not every electrician is a qualified inspector, and not every inspector gives you what you need. Three clear paths exist in Luxembourg.

Path A — SREL (Service de l'Électricité et Énergie):

• The national agency: the formal authority for new-installation acceptance and periodic compliance on regulated premises
• Only an SREL-accredited inspector can issue a conformity certificate recognised by insurers, banks and notaries
• Use for: any formal certification, pre-sale conformity on major properties, post-major-renovation acceptance, commercial periodic
• Cost: highest tier (€400–€1 800+), but the certificate carries weight

Path B — Aicae (Association des Installateurs et Constructeurs Agréés en Électricité):

• Industry body; its accredited inspectors perform verifications to the same technical standard as SREL
• Recognised by banks and notaries alongside SREL
• Use for: pre-sale conformity, post-renovation recertification, periodic commercial — when your installer recommends Aicae
• Cost: similar to SREL, sometimes 10–15 % cheaper

Path C — Independent electrician safety check:

• A Chambre-des-Métiers-licensed electrician performs a safety check using the same test procedures, but without issuing a formal SREL/Aicae certificate
• The written report has legal weight in a civil dispute but is not accepted as a conformity certificate by some banks or insurers
• Use for: peace-of-mind checks before buying a cheaper property, periodic household safety, insurance-response documentation
• Cost: lowest tier (€180–€480)

How to pick the right path:

• Buying a property over €600 000 with a mortgage: your bank will likely require SREL or Aicae
• Buying a property under €400 000 all-cash or with an older existing mortgage: independent electrician safety check is usually enough
• Selling a property over €500 000: offer an up-front SREL or Aicae report; removes buyer-side haggling
• Ongoing household: independent electrician every 10–15 years is good practice
• Commercial workplace: SREL or Aicae on the mandated 3-year cycle

Verification questions to ask any inspector:

• "What is your SREL or Aicae accreditation number?" (Every legitimate inspector has one)
• "Is the certificate you issue recognised by Luxembourg banks and insurance companies?" (Only SREL/Aicae; independents produce a report, not a certificate)
• "How long is the resulting document valid?" (Standard: 3 years commercial, indefinite for private residential unless major work is done)
• "What is your test-equipment calibration date?" (Should be within the last 12 months)
• "What happens if my property fails — do I get a list of corrective actions with cost estimates?" (Good inspectors 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
