A home emergency never gives you notice. A water leak at 2am, a door that slams shut on a Sunday, an electrical panel sparking in the middle of winter: in moments like these, people often overpay because they decide in a panic. This guide brings together, for the six most common home emergencies in Luxembourg, the immediate steps to take, who to call, the real costs (call-out, labour, night and weekend surcharges) and the classic scams of emergency call-outs.
The goal is simple: help you act fast, recognise a fair price, and never sign under pressure.
Rule number one: make it safe before you call
Before you even look for a tradesperson, every emergency has one priority safety action. In most cases, that single action limits the damage and lowers the final bill.
- Water leak: shut off the main water supply (turn clockwise).
- Gas smell: don’t touch any switch, ventilate, and call the fire brigade on 112.
- Electrical danger (smoke, burning smell, sparks): switch off the main breaker, and 112 if a fire starts.
- Break-in: touch nothing and call the police on 113.
These emergency numbers are free. A tradesperson is never your first call when there’s an immediate risk to people.
Water leak: shut off, mop up, call an emergency plumber
The water leak is the most dreaded home emergency, because the damage adds up within hours. In Luxembourg, the average cost of water damage runs from €2,000 to €8,000 — which is exactly why cutting off the water immediately matters so much.
The first 5 minutes:
- Close the main stopcock (cellar, garage, under the sink or near the meter).
- Cut the electricity if water is reaching sockets or the panel.
- Mop up, protect furniture, ventilate.
- Photograph the source and the damage for your insurer.
Who to call? An emergency plumber. Then notify your insurer within 5 working days and, if you rent, your landlord.

Emergency locksmith Luxembourg: locked out or a jammed lock
A door slamming shut with your keys inside, a key snapped in the barrel, a seized lock: locksmithing is the field where emergency scams are most widespread. The good news is that a simple locked-out door can usually be opened without breaking anything.
While you wait for the locksmith:
- Don’t force the door (the damage costs far more than the opening).
- Check for a safely accessible open window.
- Contact the landlord, agency or a trusted neighbour who might hold a spare key.
Costs (source: Emergency Locksmith Luxembourg: door opening):
| Job | Day rate | Night/weekend |
|---|---|---|
| Open slammed door (simple) | €80-150 | €120-250 |
| Open slammed door (complex) | €120-200 | €180-300 |
| Opening + lock replacement | €150-400 | €220-550 |
| Broken key extraction | €80-150 | €120-220 |
Classic scam to avoid: the locksmith quotes a very low price on the phone then multiplies the bill on site, or insists on drilling the lock when a simple opening is possible. A daytime locked-out door opening billed at €350-600 is a rip-off: the fair price is €100-150.
Emergency electrician Luxembourg: danger before cost
A total power cut, a breaker that keeps tripping, a socket that heats up: some electrical faults are dangerous. The priority is to make things safe, not to repair them yourself.
Immediate danger (burning smell, smoke, sparks, exposed cable, an electric shock felt from an appliance): switch off the main breaker, evacuate if needed, and call the fire brigade on 112. Never throw water on an electrical fire.
Total outage, no danger: check whether your neighbours are affected too (grid problem), inspect the main and residual-current breakers, but never force a breaker that refuses to reset.
Costs (source: Emergency Electrician Luxembourg 24/7):
| Service | Average cost |
|---|---|
| Emergency call-out | €120-250 |
| Emergency hourly rate | €90-180/h |
| Fault diagnosis | €150-300 |
| Simple job (1-2h) | €250-500 |
At night (22:00-06:00), expect €300-600 for a 1-2 hour job, with surcharges of 60-100% over the daytime rate.
Heating breakdown in winter: a genuine emergency
With temperatures dropping to -10°C, a heating breakdown isn’t just about comfort: it exposes you to frozen pipes, and a burst pipe costs between €500 and €3,000 to repair.
Before you call, a few simple checks solve a good share of breakdowns:
- Check the boiler pressure (between 1 and 1.5 bar).
- Check the thermostat (batteries) and the boiler breaker.
- Make sure there’s still fuel.
- Bleed lukewarm radiators from the top.
To get through until the technician arrives, a portable electric heater (€20-100) will do — never left unattended, and never a barbecue or camping stove indoors.
Costs (source: Heating breakdown in winter: emergency repair):
| Time | Call-out | Hourly rate | 1-2h job |
|---|---|---|---|
| Weekday | €80-150 | €70-120/h | €200-400 |
| Night | €150-250 | €120-200/h | €350-700 |
By fault type: pressure too low €100-200, seized circulation pump €330-750, faulty burner €400-1,000.
Broken window: secure first, replace later
Break-in, storm or accident: a broken window is handled in two stages. You first secure the opening, then replace the glazing — sometimes the next day.
First steps: don’t touch the shards with bare hands, keep children and pets away, pick up with gloves. After a break-in, don’t go in, call the police on 113, and touch nothing before they arrive.
Temporary fix while you wait for the glazier: a plywood panel (10-15mm) fixed from the inside lasts several weeks. Cardboard or a tarp only cover you for 24 to 48 hours.
Costs (source: Broken window: emergency replacement and securing):
| Service | Weekday | Night/Sunday |
|---|---|---|
| Emergency call-out | €60-100 | €100-200 |
| Temporary securing | €80-200 | €150-350 |
| Single glazing replacement | €150-350 | €250-600 |
| Double glazing replacement | €250-600 | €450-1,000 |
Blocked drain: try before you call
Not every blocked drain is an emergency. A slow sink often clears on its own; it’s sewage backing up or an overflowing toilet that justify an immediate call.
Try before you call: a plunger (60-80% effective, €5-15), removing the trap, or a drain snake. Avoid harsh chemical products: they damage pipes and are dangerous to you.
Call a plumber for an overflowing toilet, sewage backflow, several blocked drains at once, or when home methods fail.
Costs (source: Blocked drain: solutions):
| Service | Cost |
|---|---|
| Plumber drain clearing | €100-300 |
| Emergency job | €150-350 |
| High-pressure jetting | €150-400 |

Scams to avoid, whatever the trade
Emergency call-out scams follow the same pattern everywhere. Be wary of a tradesperson who:
- Refuses to give a quote, even a rough one, over the phone.
- Quotes a very low price then inflates the bill once on site.
- Has no Luxembourg VAT number (format LU + 8 digits).
- Demands cash-only payment.
- Insists on replacing rather than repairing, or on drilling a lock that could simply be opened.
- Turns up without an identified vehicle or professional workwear.
A serious professional arrives with a branded vehicle, shows a trade card, and issues a detailed invoice with VAT. Always ask for a quote before the work and never sign under pressure.
On the insurance side, most home policies cover water damage, windows broken after a break-in or storm, and sometimes 24/7 breakdown assistance. The usual excess in Luxembourg is €250-500. Contact your insurer quickly and keep every invoice.

FAQ
What number should I call in an emergency in Luxembourg?
For immediate danger (fire, gas leak, flooding, accident), call the fire brigade on 112. For a break-in or burglary, call the police on 113. These numbers are free. For a call-out with no risk to people (locked-out door, blocked drain), contact a tradesperson directly.
How much does an emergency call-out cost at night?
It depends on the trade, but night surcharges (22:00-06:00) generally run from +50% to +100% over the daytime rate. In practice: a night-time plumber costs €300-600, an electrician €300-600, a heating engineer €350-700 and a locksmith up to €250-300 for a door opening.
How do I spot an emergency call-out scam?
The warning signs are a refusal to quote over the phone, a low price that explodes on site, no Luxembourg VAT number, cash-only payment demands, and pressure to replace or drill rather than repair. Always insist on a written quote and a detailed invoice.
Does my home insurance cover emergencies?
Often partly. Most policies cover water damage and windows broken after a break-in or storm; some include 24/7 breakdown assistance. The usual excess is €250-500. Notify your insurer within 5 working days and keep all proof (photos, invoices).
Who pays for the repair, tenant or landlord?
As a rule, the landlord covers repairs linked to wear and major equipment (pipes, water heater, boiler). The tenant handles routine upkeep (seals, bleeding radiators) and damage caused by negligence. Always report the fault quickly, by phone then in writing.
