Car dealer compliance in Liechtenstein follows Swiss energy label law, not a law of its own: under the Customs Treaty with Switzerland, the Swiss Energy Efficiency Ordinance (EnEV) applies in the version listed in the Kundmachung LGBl. 2026 No. 312, in force since 18 September 2026. Every new car with up to 2,000 km therefore carries the energy label made with the SFOE online tool, and every advert states consumption, CO2 emissions and, for passenger cars, the energy efficiency category A to G. Financing adverts, on the other hand, follow Liechtenstein's own Consumer Credit Act (KKG), which asks for a representative example and a sentence on your role as credit intermediary, without the warning EU countries add on 20 November 2026. Vehicle Hub keeps both as a rule set for Liechtenstein, in German and in Swiss francs.
Swiss changes reach Liechtenstein only when the government announces them, and Vehicle Hub follows that date, not the Swiss one. That is why a car on your website will still show the 2026 average of 111 g/km for new cars after 1 January 2027, until a new Kundmachung lists the Swiss values for 2027. You enter the category from the SFOE label once; the car's page, built with the Vehicle Hub widgets, shows the official SFOE graphic, and the exposé and price sign show the letter. Each check is described under car dealer mandatory information, and the car labelling directive by country overview sets Liechtenstein next to Switzerland and Austria. Vehicle Hub applies the published rules; it does not give legal advice.
