What Electrical Standards Must Be Followed in a Kitchen?
Because the kitchen is a room where potential hazards are numerous, French regulations establish very strict rules to ensure your safety and comfort. ENGIE explains all the standards you need to follow to ensure a compliant electrical installation in your kitchen.
When a property project is approaching, one crucial step is designing the kitchen. The choice of furniture and household appliances often receives most of the attention from homeowners—and understandably so. Who hasn’t dreamed of having a beautiful kitchen that is comfortable and enjoyable to use?
However, for your kitchen to be as practical and functional as it is aesthetically pleasing, it is important to ensure that the design of the electrical installation matches your needs. This is especially important because kitchen electrical systems in France are subject to strict standards that must be respected.
ENGIE therefore provides all the useful legal guidance and practical advice to help you design the ideal electrical layout for your kitchen.

The NF C 15-100 standard: the central reference for kitchen electricity
In France, electrical installations in homes are governed by the NF C 15-100 standard. This regulation summarizes all safety and operational requirements for electrical installations in residential buildings, room by room, including the kitchen.
Within this standard, Amendment 5 often referred to as the NF C 15-100 kitchen standard lists all specific requirements for kitchens due to the particular types of equipment connected there.
These requirements mainly concern:
the number and placement of electrical outlets,
the types of circuits dedicated to specific appliances,
and lighting installations.
When do these standards apply?
Electrical standards in France have evolved significantly in recent years. As a result, compliance is mandatory for new homes, while some flexibility is allowed for older properties.
If you are only carrying out minor work in your kitchen, you may temporarily keep your existing electrical installation.
However, if you plan to undertake a major kitchen renovation, you must bring the installation up to standard in order to obtain a Certificat de Conformité (Certificate of Compliance).
This document is also required when selling your property. In addition, a home whose kitchen meets modern safety and functionality standards is generally more attractive to buyers.
Electrical standards in a kitchen: number and placement of electrical outlets
The standard first defines the minimum number of electrical outlets required in a kitchen:
For a kitchen smaller than 4 m²: at least 3 outlets.
For a kitchen larger than 4 m²: at least 6 outlets.
The placement of these outlets is also regulated.
For kitchens larger than 4 m², at least four of the six outlets must be located above the worktop, at a minimum height of 8 cm above the countertop.
The remaining outlets must be installed between 12 cm from the floor and a maximum of 1.30 m above the floor.
The standard also specifies certain prohibitions. In particular, outlets cannot be installed above cooking hobs or above the sink.
However, an additional outlet may be installed for the kitchen hood, positioned at 1.80 m above the floor.
It should also be noted that the main light switch must be located near an outlet and close to the kitchen entrance, typically between 90 cm and 1.30 m above the floor.
These rules aim to ensure the design of kitchens “whose daily use is functional and suited to the presence of many electrical appliances.” In practice, complying with the standard helps avoid the use of extension cords or multiple potentially dangerous connections on a single power strip.
Electrical standards in a kitchen: required electrical circuits
The kitchen is one of the rooms in a home that contains the largest number of electrical appliances, some of which require dedicated connections.
For this reason, the standard requires certain equipment to be connected to dedicated electrical circuits, protected by an appropriate circuit breaker and connected to a suitable outlet.
More specifically, the standard specifies the following requirements:
Grounded outlets are limited to six per circuit, protected by a 20-amp circuit breaker maximum. If you need more outlets, you must plan additional circuits.
A dedicated circuit protected by a 20-amp circuit breaker, using a 2.5 mm² cable, must be provided for appliances such as:
the kitchen hood,
the electric oven,
the dishwasher,
the washing machine,
and the freezer.
A dedicated circuit protected by a 32-amp circuit breaker, with a 6 mm² cable, must be installed specifically for electric cooktops.
Electrical standards in a kitchen: lighting requirements
Kitchen lighting is also regulated by the NF C 15-100 kitchen standard.
It requires that at least one ceiling light point be installed in the kitchen. This electrical connection must be equipped with a DCL (Dispositif de Connexion Luminaire), a standardized device designed to safely connect lighting fixtures.
If installing a ceiling light is not possible, the kitchen must include at least two wall light fixtures.
Electrical standards in a kitchen: RJ45 communication outlets
Another specific requirement of the NF C 15-100 kitchen standard concerns RJ45 communication sockets.
If your kitchen is open to the living room (open-plan kitchen):
The space must include at least one RJ45 socket if the total area is less than 28 m².
It must include two RJ45 sockets if the total area exceeds 28 m².
This requirement does not apply directly to separate kitchens, and it only concerns new constructions.
Indeed, the standard primarily requires these sockets in the living room and, when applicable, in the bedrooms of the house.
RJ45 sockets carry low-voltage signals and are commonly used for multimedia connections, such as television, internet, or home automation devices.
No changes expected in the short term
These standards are not expected to change in the near future, meaning they should remain applicable for several years.
The last modification to the NF C 15-100 standard dates back to the decree of August 3, 2016, which regulates electrical installations in residential buildings.
Why comply with the NF C 15-100 standard?
The NF C 15-100 kitchen standard is very detailed because its main goal is to protect both people and property by preventing risks such as:
electric shock,
fire,
overvoltage,
short circuits,
leakage currents.
It also aims to ensure the comfort and proper use of electrical equipment while taking into account technological and safety developments.
So why is compliance important?
The kitchen is one of the rooms where the highest number of household accidents occurs. Because water is frequently present, contact with an electrical outlet or switch can become dangerous.
In addition, poorly designed electrical installations, with circuits that are not suited to high-energy appliances, can damage your equipment.
Finally, obtaining a certificate of conformity, issued when your kitchen electrical installation meets current standards, is mandatory when selling your property. It is also required when carrying out a complete renovation of your kitchen.
Additional practical installation tips beyond the standards
Electrical standards represent the minimum legal framework.
In a modern kitchen, six outlets may not be enough to ensure a comfortable and fully functional space. It is therefore important to adapt the number of outlets to your real needs.
To determine this, try to visualize how you will use your future kitchen before starting your construction or renovation project.
Start by identifying large appliances that require dedicated outlets, such as:
your dishwasher,
your electric oven,
your freezer,
possibly your washing machine,
your kitchen hood.
Then consider the small appliances you may want to keep on your countertop for everyday use:
toaster,
coffee machine,
kettle,
food processor, etc.
Finally, count the additional devices you may want in your kitchen:
smartphone charging points,
TV connection,
or other equipment.
You can then calculate the total number of outlets required for the appliances you plan to keep plugged in regularly.
The same applies to lighting. The standard only defines a minimum requirement, and a single light source may not always be sufficient.
Feel free to add additional lighting fixtures, for example to illuminate the worktop or cooking area.

Kitchen electrical standards: key points to remember
Like all electrical installations in your home, the electrical layout of your kitchen must comply with the NF C 15-100 standard.
This standard includes specific requirements for kitchens, particularly regarding: the number of outlets required, their type and placement, the types of electrical circuits required and lighting installations.
Although these rules may seem restrictive, their main objective is to ensure the safety of residents and the protection of kitchen appliances.
It is also important to note that the standard only sets minimum requirements. If these seem insufficient for a kitchen that is truly practical and comfortable, you can absolutely increase the number of outlets or lighting points.
If you are planning to redo the electrical installation in your kitchen, consider seeking professional support. ENGIE experts are fully familiar with current regulations and can provide practical advice to design a kitchen perfectly suited to your needs.
Are there other rules to follow in a kitchen?
Because the kitchen is a central living space in the home and one of the rooms with the most potential hazards, its layout is highly regulated.
For example, there are specific ventilation standards, especially if you cook using gas appliances.
What is the minimum distance between a power outlet and a sink?
It is strictly forbidden to place an electrical outlet directly above a sink.
However, the standard does not specify an exact minimum distance between an outlet and a water point.
In practice, a minimum distance of around 60 cm between a kitchen sink and an electrical outlet is generally considered reasonable.
What is the main electrical risk in a kitchen?
The most common risk is electrical fire, although modern circuit breakers are increasingly sensitive and can prevent circuit overloads, significantly reducing this risk.
The risk of electric shock, or in extreme cases electrocution also exists, even though modern protection devices have significantly improved safety over time.
