Central vacuum system cost in Luxembourg (2026)

A €3 200 turnkey quote with TVA at 17 % becomes €3 744 TTC; the same quote at 3 % super-reduced (qualifying principal residence renovation) becomes €3 296 TTC — confirm the TVA line before comparing.

What a typical turnkey package contains:

• Motor unit (2.0 to 3.5 kW) with exhaust outlet, dirt canister, soundproof housing option
• Rigid PVC pipework sized per manufacturer spec (usually 50-mm internal diameter)
• Wall inlets with metal cover plates matching the home's electrical accessory line
• One or two 9–12-m hoses with ergonomic handle, power-switch trigger and hose sock
• Attachment set — combination floor head, parquet brush, crevice tool, upholstery tool
• Initial commissioning, customer walkthrough, 2-year workmanship warranty

Outside the headline quote:

• Kick-plate floor inlets in the kitchen and entrance (brush-and-sweep directly into the system) — €120 to €180 each additional
• External venting through a stone façade — €120 to €300 in core-drilling and weatherproof cap
• A soundproofing housing box for an unusually loud motor unit — €250 to €450
• Smart-home integration (start/stop, filter-full alerts via app) — €200 to €450

The biggest single factor on the invoice is whether the house is under construction or already finished. Running rigid PVC through open stud walls and bare concrete slabs is straightforward. Running the same pipes through finished rooms, behind parquet and under painted plaster, doubles the labour time and adds painter/tiler follow-ups.

New-build (installation during construction):

• Piping installed at second-fix stage before plastering and flooring
• No demolition, no dust, no repainting
• A 4-inlet system in a new 180-m² house sits at €2 400 to €3 200 installed
• Typically coordinated with the electrician's wiring path to share chases

Retrofit in a finished home:

• Piping runs through cupboards, utility cores, unused fireplace flues, or along service columns
• Some runs may need to go externally (weather-clad) rather than internally
• A 4-inlet retrofit in an existing 180-m² house sits at €3 200 to €4 300 — roughly 30 % more than new-build
• Painter and tiler follow-up costs add €200 to €700 depending on the number of chases

Partial retrofit during a renovation:

• If you are already renovating a floor or a whole house (new floor, new ceilings, plasterboard out), adding central vacuum piping during the works is close to the new-build price — the walls are already open
• This is the single biggest cost-saving moment for a central vacuum upgrade

Retrofit paths that work well in Luxembourg homes:

• Existing chimney flues disused by a heat-pump conversion — ready-made vertical duct between floors
• Void spaces behind built-in wardrobes — common in older Luxembourg-Ville apartments
• Attic to top-floor run under eaves, then down an internal column
• Basement ceiling runs horizontally across multiple rooms at once

Retrofit paths that do not work:

• Concrete-slab floors between storeys without existing service penetrations — cannot be practically cut
• Solid stone walls on older farmhouse properties in the Oesling — core-drill risk and aesthetic damage

Two system architectures dominate the 2026 Luxembourg market — classic wall inlets with a stored hose, and retractable hose-in-the-wall ("hide-a-hose") systems where the hose lives inside the pipe.

Classic wall inlets:

• 5 to 9 inlets in a typical home, each within a 9-m hose reach of any corner
• A separate 9- or 12-m hose is carried from room to room and plugged in
• Hose storage: wall-hung hanger or a cupboard hook — requires wardrobe space
• Price impact: lower system cost, higher everyday effort

Hide-a-hose systems:

• 2 to 4 inlets in a typical home, each storing a 15- to 17-m hose inside the suction pipe
• Pull out the hose from the inlet, clean, let it retract
• Hose storage: none — the hose is always in the wall
• Price impact: €500 to €900 more on a 4-inlet house versus a conventional 4-inlet system
• Marginal labour: larger pipe diameter on the hose paths (usually 60 mm) and a larger backing box

When hide-a-hose is worth the uplift:

• Daily-use households where storing a 12-m hose in a cupboard is annoying
• Multi-storey homes where each floor needs its own inlet — fewer inlets required
• Renovations where one hide-a-hose inlet can cover a whole floor of 90 m²

When classic inlets make more sense:

• Small apartments where a single inlet and a cupboard-kept hose is ergonomic
• Tight budgets where the €500–€900 uplift matters
• Homes with lots of partition walls — the 17-m hide-a-hose can snag on corners

A hybrid approach that works:

• Hide-a-hose on the main living floor (always visible, often cleaned)
• Classic inlets on the bedroom floor (used weekly, hose lives in the linen cupboard)
• Classic inlet in the utility room for outdoor access
• This blend typically sits at €3 200 to €4 200 in a 4-bedroom home

Central vacuum installation is a declared trade. The installer holds an Autorisation d'établissement in the electrician or HVAC-installer category and signs a dedicated manufacturer training certificate for the chosen brand.

A compliant invoice contains:

• Business name, Luxembourg address, Autorisation d'établissement number
• TVA number starting with LU
• Itemised lines — motor unit, piping and fittings, inlets, hose kit, accessories, labour
• Commissioning report with measured vacuum at the farthest inlet
• 2-year workmanship warranty plus a 5- to 10-year motor warranty from the manufacturer

TVA rates:

• Standard 17 % on new-build and second-home installations
• Super-reduced 3 % (logement taux super-réduit) on qualifying renovation of a principal residence — the installer handles the declaration, you sign the usage statement
• The 3 % rate is capped per residence; the installer's software tracks the remaining envelope

Electrical compliance:

• The motor unit is hard-wired to a dedicated 16-A circuit via a wall-mounted isolator
• The installer issues a Procès-Verbal de Conformité for the dedicated circuit
• Low-voltage wiring runs alongside the suction piping between inlets for the on/off switching at the hose handle — included in the standard install

Exhaust and air quality:

• Motor units vent filtered air — usually out through an external wall via a weather-protected hood
• Internal-vent units (no external opening) use HEPA-grade filtration — suitable for apartments where external venting is not practical, at €150 to €300 price uplift
• Noise level at the motor: 65–72 dB(A) direct; with a soundproof housing, 55–60 dB(A) — important where the motor sits near a bedroom wall

Warranty structure:

• Workmanship warranty (the installer): 2 years, covers piping leaks, inlet failures, poor termination
• Motor warranty (the manufacturer): 5 to 10 years depending on brand and model
• Hose and accessories: typically 1 year

When the installer is not also your electrician:

• A central vacuum installer may not be your main electrician; confirm they coordinate on the dedicated circuit and the consumer unit
• If the consumer unit is full, the electrician quotes the consumer-unit upgrade separately — €400 to €900

A central vacuum system is designed to last 20 to 30 years. Running costs in Luxembourg are modest, maintenance is predictable, and the total cost of ownership over 15 years compares favourably with replacing two or three high-end upright vacuums.

Annual running cost in Luxembourg (2026 tariff):

• Electricity: a 2.0-kW motor running 60 minutes per week consumes roughly 100 kWh/year → €22/year at €0.22/kWh
• Filter bags or reusable cloth filter: €20 to €40/year
• HEPA filter replacement every 2 to 3 years: €45 to €80
• Total annual running cost: €50 to €75

Scheduled maintenance:

• Empty the dirt canister every 4 to 6 weeks for an average household; every 2 weeks for households with pets
• Replace the bag (if bagged) every 3 to 6 months
• Replace the HEPA filter every 2 to 3 years
• A 10-year check-up by the installer at €120 to €200 covers pipe-integrity test, motor-brush inspection and filter replacement

Lifespan and parts:

• Motor brushes: 2 500 to 4 000 hours of use before replacement — roughly 12 to 20 years of household use
• Motor itself: 20–30 years
• Piping: indefinite (rigid PVC doesn't degrade at indoor temperatures)
• Hoses: 5 to 10 years depending on handling; ribbed hoses outlast smooth types

Comparison to upright / stick vacuums:

• A €800 high-end stick vacuum lasts 5 to 8 years before battery degradation
• Three stick vacuums over 15 years = €2 400 plus disposal
• A €3 000 central vacuum over 15 years = €3 000 install + €750 to €1 125 running — total €3 750 to €4 125
• The central system wins on performance (unlimited runtime, higher airflow), loses on pure cost unless installed during new-build or renovation

Warranty-voiding behaviour to avoid:

• Vacuuming construction dust without a specific site-vacuum filter — fine powder clogs the motor
• Vacuuming standing water — the motor is not rated for wet pickup on most domestic systems
• Emptying the canister while the motor is running

Central-vacuum quotes vary more than most because the combination of motor power, inlet count, piping route and hose type gives many ways to hit a similar-looking number. Normalising the brief is essential.

The six checks that matter:

• Inlet count and location plan. Require a marked floor plan on the quote — which rooms have an inlet, how many, where on the wall
• Motor sizing. A 1.8-kW motor is fine for 4 inlets, an 8-inlet house needs 2.4 to 3.0 kW. Under-sized motors deliver weak suction at the farthest inlet
• Piping diameter and brand. 50-mm system is the standard; a 60-mm system for hide-a-hose costs more but performs better on long runs
• Hose length and number. Two 12-m hoses in a 4-inlet house is standard; a single 9-m hose at that scale means running back to change inlets more often
• TVA rate quoted. 17 % standard, 3 % super-reduced if eligible — confirm in writing
• Follow-up trade costs. On retrofit, who pays for the painter, tiler and plasterer after the chases are closed?

A clean briefing pack to hand to all three installers:

• Floor plan with desired inlet positions
• Photos of the proposed motor-unit location (cellar, garage, technical cupboard)
• Existing consumer-unit photo
• Wall and ceiling construction notes (plasterboard, concrete slab, hollow brick)
• Is this a renovation or a new-build context?
• Preferred hose type (conventional, hide-a-hose, hybrid)
• Exhaust venting preference (external wall or HEPA internal)

How to compare the three numbers:

• Normalise all three to TVA-inclusive totals
• Convert every difference into a line — "quote A has 6 inlets, quote B has 4, add two inlets at €350 each to B"
• Include painter/tiler follow-up on retrofits
• Include the consumer-unit upgrade if one quote assumes an existing free breaker and another adds the upgrade
• Three installers on the same brief typically land within ±15 %; wider spreads trace back to motor sizing or piping diameter differences

Five specific traps recur on central-vacuum projects in Luxembourg.

Hidden costs to plan for:

• Plastering and painting after chases. A retrofit adds €200 to €700 in follow-up trade, usually missed from the headline installer quote
• Consumer-unit upgrade. A full breaker panel cannot take the dedicated 16-A circuit — €400 to €900 of electrical work
• Exhaust routing on stone facades. Old Oesling farmhouse facades are difficult to drill cleanly — €200 to €500 for custom weather-cap work
• Soundproofing after the fact. A motor in a thin-wall cellar next to a bedroom is loud — retrofit soundproofing housing at €250 to €450
• Hide-a-hose accessory upgrade. The longer 17-m hose may not come with a parquet-safe brush or pet-hair powerhead — €90 to €280 in additional accessories

Red flags — walk away:

• No marked floor plan on the quote
• No measured-vacuum performance figure guaranteed at the farthest inlet
• Cash-only, no TVA number, no Procès-Verbal for the dedicated circuit
• Motor-unit proposed without a dedicated breaker (should be a 16-A dedicated circuit)
• Piping proposed in the same chase as water lines with no separation layer
• Undersized 1.3-kW "residential" motor offered for an 8-inlet house — will underperform within months
• No commissioning report in the quote
• Discount for "not declaring" the 3 % super-reduced work — illegal, voids insurance

When a price looks too low: A "€900 all-in" quote for a 4-inlet retrofit is below the material cost of a real declared install. A declared 4-inlet retrofit sits at €2 100–€3 200 minimum including the Procès-Verbal. Anything meaningfully below is either undeclared, missing the motor-dedicated circuit, or skipping the follow-up trades.

Insurance implications:

• Home insurance typically covers water damage from a central-vacuum pipe burst if the installer is declared with an Autorisation d'établissement and a Procès-Verbal on file
• An undeclared install voids this coverage — a motor fire or pipe failure in a cellar can cascade into structural damage not reimbursed

A central vacuum install takes 1 to 4 working days depending on scope. Coordinating with the other trades in the house saves both budget and plaster-patching pain.

Timelines by scope:

• 2-inlet flat retrofit — 1 day, mostly piping through one unused chimney flue and two wall chases
• 4-inlet semi-detached new-build — 2 days during second-fix stage
• 4-inlet semi-detached retrofit — 3 to 4 days, with painter follow-up booked for a week later
• 6-inlet detached family home new-build — 2 to 3 days during second-fix
• 6-inlet retrofit with hide-a-hose — 4 to 5 days plus plasterer and painter follow-up

New-build coordination:

• The central-vacuum installer works immediately after the electrician pulls the wiring
• Piping sits on the ceiling of the cellar or in the same stud wall as the electrics, labelled to avoid confusion
• Floor screed should not have been poured yet if a basement-ceiling route is planned
• Commissioning happens once the motor unit is mounted and the dedicated breaker is in place

Retrofit coordination:

• Booking order: central-vacuum installer first, then plasterer for chase closure, then painter, then flooring if disturbed
• Allow 3 to 4 weeks in the calendar for the full chain
• If tiles need to be lifted and relaid, add a tiler and a fortnight for adhesive cure

Handover documentation:

• Marked plan with final inlet positions
• Motor unit model, serial number, installation date
• Dedicated circuit breaker position number (for future electricians)
• Pipe route schematic (for future renovations)
• Procès-Verbal de Conformité
• Manufacturer warranty registration receipt
• User manual and accessory catalogue

Training the household:

• 30-minute walkthrough with the installer at commissioning
• Where the canister empties, how often, which type of bag
• Filter-replacement schedule
• What not to vacuum (water, large debris, fireplace ash)
• Kick-plate floor inlet operation where present
