How much does a KNX installation cost?
A fair question, and an honest answer: 'it depends'. Here are concrete benchmarks to place your project before the quote.
Benchmarks, not a price per square metre
No two KNX installations are alike: the budget depends on surface area, the number of rooms and functions, the choice of brands and the state of the building (new build or renovation). The figures below are purely indicative, to give a sense of scale.
The only way to know your real price is a personalised, free and detailed quote, drawn up after a first visit. We present it line by line, with no jargon and no hidden costs.
Three budget benchmarks (indicative)
Focused scope
Lighting and blinds in a few key rooms. The ideal entry point for a first, expandable stage. [TO COMPLETE: indicative range, e.g. from €X.]
Whole house
Lighting, blinds, heating and scenes across the whole home. The heart of a real KNX installation. [TO COMPLETE: indicative range.]
Premium & bespoke
Extended automation: energy, security, multiroom, premium finishes and specific integrations. [TO COMPLETE: indicative range.]
What makes the price vary
Surface & number of rooms
The more rooms and points to control, the more wiring and programming.
New build or renovation
In new builds the wiring is free and economical; in renovations, wireless KNX or cable routing affect the cost.
Functions & brands
The number of automations and the finish of switches and screens weigh on the budget.
Common budget questions
Does KNX cost more than a conventional installation?+
At installation there is a premium over traditional electrics. But it pays back through energy savings, comfort and added property value — and above all through expandability, which avoids redoing everything later.
Can the project be spread over time?+
Yes. You can wire intelligently from the start, then activate functions in stages: lighting and blinds first, heating and energy later, without redoing anything.
Is the quote chargeable?+
No. The first visit and the detailed quote are free and with no obligation.
Are there grants or subsidies?+
Depending on the works (energy renovation, photovoltaics), grants may exist in Luxembourg. We point you to the relevant schemes at the time of the project.
