Last reviewed: October 2026 · Sources listed at the end of this page.

Regulation (EU) 2016/426 of the European Parliament and of the Council of 9 March 2016 on appliances burning gaseous fuels — the "Gas Appliances Regulation" or GAR — replaced Directive 2009/142/EC and has applied since 21 April 2018. It covers appliances burning gaseous fuels used for cooking, refrigeration, air-conditioning, space heating, hot water production, lighting, washing, and forced-draught burners, together with fittings (safety devices, controlling devices, regulating devices, sub-assemblies). The Regulation was published in the OJEU as OJ L 81, 31.3.2016, p. 99.

Scope: products covered

Article 1 applies to "appliances" and "fittings" as defined in Article 2:

• Appliance (Article 2(1)) — an appliance burning gaseous fuels used for cooking, refrigeration, air conditioning, space heating, hot water production, lighting, or washing, and forced-draught burners and heating bodies to be equipped with such burners.
• Fitting (Article 2(2)) — a safety device, controlling device, or regulating device, and sub-assemblies thereof, designed to be incorporated into an appliance or assembled to constitute an appliance.

Exclusions (Article 1(3))

• Appliances specifically designed for use in industrial processes carried out on industrial premises;
• Appliances specifically designed for use on aircraft and railways;
• Appliances designed for research purposes for temporary use in laboratories.

An appliance is "specifically designed" only when the design is intended solely to address a specific need for a specific process or use (Article 1(3)). A general-purpose burner sold for use in a factory therefore remains in scope. Where other legislation covers the same aspects more specifically, this Regulation does not apply to those aspects (Article 1(4)). The rational use of energy requirement in Annex I, point 3.5 does not apply to appliances covered by an ecodesign measure (Article 1(5)).

Essential requirements (Annex I)

Annex I sets the essential requirements for appliances and fittings, organised into:

• General conditions — appliances must be safe under normal use, with instructions and warnings appropriate to the level of competence expected of users.
• Materials — appropriate for intended use, resistant to mechanical, chemical, and thermal conditions to which they will be subjected.
• Design and construction — structural soundness; safety devices including flame supervision and protection against gas leakage; ignition; combustion (correct combustion, completeness, prevention of carbon monoxide and unburnt fuel emission); rational use of energy; surface temperatures; and other hazards identified in Annex I, point 3.

Categories of gas supply

The Regulation distinguishes appliance categories based on the gases and pressures they are designed to use, set out in EN 437 (test gases and pressures). Appliances are designated with codes (e.g., I3B/P, II2H3B/P, III1ab2H3+) corresponding to the gas families (1 — town/manufactured gas; 2 — natural gas; 3 — LPG) and sub-categories. Member States communicate the types of gas and corresponding supply pressures used on their territory (Article 4 and Annex II), and the Commission publishes them in the OJEU; appliances must be designed for the gas supply conditions of the Member State of destination.

Conformity assessment procedures

Article 14 and Annex III provide modules for appliances and for fittings.

Appliances

• Series-manufactured appliances and fittings: Module B (EU-type examination, production type) with, at the manufacturer's choice, Module C2 (supervised product checks at random intervals), D (production quality assurance), E (product quality assurance) or F (product verification) (Article 14(2)).
• Single units or small quantities: any of the above, or Module G (unit verification) (Article 14(3)).

Fittings

Fittings follow the same module options, because Article 14 applies to both. Fittings placed on the market on their own carry the CE marking and come with a declaration of conformity. Recital 49 describes them as intermediate products for appliance manufacturers.

Notified Body involvement is required for all GAR appliances and fittings, since every route includes Module B or Module G. Under Article 17(3), the CE marking is followed by the identification number of the Notified Body involved in the production control phase and by the last two digits of the year in which the CE marking was affixed.

Technical documentation

Annex III, Module B (and others) requires: a general description of the appliance/fitting; conceptual design and manufacturing drawings; descriptions necessary to understand the drawings and operation; list of harmonised standards applied; results of design calculations and examinations; test reports. Retention: 10 years after the appliance or fitting has been placed on the market (Article 7(3)). See technical documentation.

EU Declaration of Conformity

Article 15 and Annex V set the Declaration's contents. For fittings, it must also state the fitting's characteristics and give instructions on incorporation into an appliance. A copy accompanies each fitting, although a single copy can cover a large batch delivered to one user. Where several Union acts apply, for example the LVD and EMC Directive, one declaration covers them all, identifying each act. See EU Declaration of Conformity.

Marking and labelling

Article 17 requires the CE marking, the Notified Body identification number and the last two digits of the year of affixing. Article 18 and Annex IV require the appliance or its data plate to bear the manufacturer's name, registered trade name or registered trade mark, the type, batch or serial number, the type of electrical supply where applicable, the appliance category marking, the nominal supply pressure, and the information necessary for correct and safe installation. Fittings bear the same information as far as relevant. See affixing the CE mark.

Harmonised standards

The references of harmonised standards under the Regulation are listed in Commission Implementing Decision (EU) 2024/2944, as amended by Implementing Decision (EU) 2025/1793, and in Implementing Decision (EU) 2026/1750 of 20 July 2026 (EN 17476:2021 for LPG vapour pressure appliances and EN 497:2022 for multi-purpose boiling burners for outdoor use). They include the EN 30 series (domestic cooking appliances), the EN 203 series (gas-heated catering equipment), EN 15502-1, EN 15502-2-1 and EN 15502-2-2 (gas-fired heating boilers), and standards for safety and control devices such as the EN 88 series (pressure regulators), EN 125 (thermoelectric flame supervision devices), EN 1106 (manually operated taps) and EN 1854 (pressure sensing devices). The EN 15502 series supersedes earlier boiler standards such as EN 297, which was cited under the former Directive 2009/142/EC and does not appear in the Regulation's list. See harmonised standards.

Recent and upcoming changes

The Energy Performance of Buildings Directive (EU) 2024/1275 sets an objective of phasing out fossil-fuel boilers by 2040 and ended financial incentives for stand-alone fossil-fuel boilers from 1 January 2025. These measures concern buildings and funding, not the placing on the market of appliances: the GAR remains the market regime. The latest harmonised standards decision is Implementing Decision (EU) 2026/1750.

Related legislation

• Pressure Equipment Directive 2014/68/EU — PED Article 1(2)(f) excludes pressure equipment classified no higher than category I that is covered by the gas appliances legislation; higher-category pressure equipment remains subject to the PED.
• Low Voltage Directive 2014/35/EU — for the electrical aspects of gas appliances with electrical components.
• EMC Directive 2014/30/EU — for electromagnetic compatibility of appliances with electronic controls.
• Ecodesign — energy-related appliances remain subject to measures adopted under Directive 2009/125/EC, such as Commission Regulation (EU) No 813/2013 for boilers. See Ecodesign Regulation 2024/1781.
• Energy Labelling Regulation (EU) 2017/1369 — energy label requirements for in-scope appliances.

Common errors

• Wrong appliance category for the destination Member State. Check the gas supply conditions communicated under Article 4 and published in the OJEU for each Member State of destination, and mark the matching category.
• Missing fittings markings. Fittings placed on the market separately require their own CE mark, Declaration of Conformity, and technical file.
• Reliance on outdated EN editions. The harmonised standard list must be checked at the time of conformity assessment.
• Module A self-declaration. Module A is not available under the GAR; Notified Body involvement is required for in-scope products.

Frequently asked questions

Does a gas appliance need a Notified Body?

Yes. Every route in Article 14 includes Module B or Module G, both of which involve a Notified Body. Module A is not available.

Do I need a leak test under the Regulation?

Annex I requires appliances to be designed so that gas leakage does not present a danger. It does not prescribe one test for all products. The test method normally comes from the harmonised standard applied, and is reviewed in the type-examination.

What must an EU declaration of conformity for a gas appliance contain?

It follows the model in Annex V to Regulation (EU) 2016/426: the product identification, the manufacturer's details, the object of the declaration, the legislation and standards applied, the Notified Body and certificate details, and a signature. Where several Union acts apply, a single declaration lists them all.

Are industrial burners covered?

Only appliances specifically designed for industrial processes on industrial premises are excluded (Article 1(3)). An appliance not designed solely for such a process stays in scope. Forced-draught burners are listed in the definition of appliance.

Does the old Directive 2009/142/EC still apply?

No. It was repealed on 21 April 2018 and replaced by Regulation (EU) 2016/426. References to the Directive are read as references to the Regulation.
