Plan your kitchen sockets before the walls are chased, not after. Once the backsplash is tiled, adding a new outlet is almost impossible. So first decide which appliances you will have, then draw the plan.

This article explains in simple words how high to place kitchen sockets, how many you need, where to put them and which type to choose. At the end there is a short section on kitchen ergonomics and the work triangle.

How high should kitchen sockets be

In many countries there are no strict rules for socket height in homes, and people go by convenience. If your countertop is 85-90 cm high, the wiring is usually split into three levels.

  • Lower level, 10-15 cm from the floor. For the fridge, oven, dishwasher and washing machine.
  • Middle level, 105-115 cm from the floor, about 15-20 cm above the countertop. For the kettle, toaster, blender and coffee machine.
  • Upper level, 200-250 cm. For the hood and the power supplies of the lighting.

One important point. Always measure from the finished floor. If you only have a screed now, add the thickness of the future flooring, usually 1.5-2 cm. Otherwise the lower sockets will end up too low.

How many sockets does a kitchen need

There is no exact number, it all depends on your appliances. A small kitchen often needs 8-10 sockets, and a large one may need more than 20. It is easier to count by groups:

  • every appliance that stays in one place (fridge, oven, microwave, dishwasher, hood) needs its own socket;
  • small appliances (kettle, toaster, blender, multicooker) usually need 4-5 sockets;
  • another 2-3 sockets are useful for chargers and a vacuum cleaner.

Add a couple of spare points. In a year or two something new almost always appears in the kitchen.

It is better to connect powerful appliances on separate lines with protective breakers. An oven needs a socket with a suitable current rating, and 16 A is often mentioned in popular advice. Your electrician will confirm the exact figures.

Where to put sockets: a plan by zones

It is convenient to draw the kitchen socket plan zone by zone.

  • Built-in appliances. It is better to move the socket into a neighboring cabinet or the plinth instead of hiding it behind the appliance. Then the appliance sits flush to the wall, and you can reach the plug without taking furniture apart.
  • Backsplash by the work area. Blocks of two to four sockets are handy here. People usually advise keeping 20-30 cm away from the hob, so that splashes and steam do not reach the contacts.
  • Sink. Do not place sockets above or below the sink. Move aside and choose splash-protected models. Exact distances depend on local rules, so check them with your electrician.
  • Island. If you plan one, the cable is laid into the floor at the screed stage. Otherwise wires will have to cross the walkway.
  • Dining area. Think about where you will charge your phone and use a laptop.
  • Hidden spots. Sockets for the hood and lighting are usually hidden in the upper cabinets.

Also check how the doors of the fridge and cabinets open. They must not block access to the sockets.

Which sockets to choose

  • Standard flush-mounted earthed sockets suit most cases. They are reliable and easy to care for.
  • Next to the sink, choose moisture-protected models.
  • Pull-out and hidden blocks are good for an island and for kitchens where you do not want extra holes in the backsplash. But they take space under the countertop, and crumbs get into the gaps.
  • Corner sockets at the joint of the countertop and backsplash help avoid drilling the tiles.
  • Sockets with USB are handy in the dining area.

Kitchen ergonomics: the work triangle and walkways

Once the sockets are clear, look at the layout itself. The sink, the hob and the fridge form the work triangle. The National Kitchen and Bath Association (NKBA, USA) gives these guidelines:

  • the sum of the three sides is no more than 7.9 m, and each side is between 1.2 and 2.7 m;
  • a tall cabinet or the fridge should not stand between two work zones;
  • the triangle should not be a thoroughfare for the whole household;
  • the walkway between rows of cabinets is at least 107 cm if one person cooks, and at least 122 cm if two do;
  • next to the sink you need a flat countertop of at least 91 by 61 cm for chopping and preparing food.

The countertop height is chosen to suit the person who cooks. Drawers are more convenient than ordinary base cabinets: you see all the contents and do not have to squat. And the work area needs lighting, otherwise you cut food in your own shadow. Read more about light in the article lighting in an apartment.

For the hood, NKBA recommends a model that vents outside, from about 255 m³/h. The power is chosen to match the volume of the kitchen.

A short checklist before ordering a kitchen

  1. The socket plan is drawn by levels and agreed with the electrician.
  2. The work triangle and walkways are checked on the plan.
  3. There is no tall cabinet between the sink, hob and fridge.
  4. There is enough working space by the sink and the hob.
  5. There is light above the work area.
  6. The hood has enough power and the way of venting is clear.
  7. Appliance doors do not block the sockets.

Frequently asked questions

Can I put a socket above the sink? No. Sockets are not placed above or below the sink. Move aside and check the requirements with your electrician.

How many sockets does a kitchen need? For a small kitchen usually 8-10, for a large one sometimes more than 20. Count the appliances by groups and add a reserve.

How high should kitchen sockets be? Most often on three levels: near the floor for built-in appliances, about 105-115 cm for small appliances and 200-250 cm for the hood.

How kitchen sockets are done in different countries

There is no single world rule. Every country has its own norms, and comparing them helps you see the logic.

USA. The rules are strict. A socket is needed on every countertop section 30 cm (12 inches) wide or more. From any point along the wall behind the countertop, the nearest socket must be no more than 61 cm (24 inches) away. Above the countertop, a socket is placed no higher than 51 cm (20 inches). An island needs at least one socket, and it can be a pull-out one. Sockets on the countertop and near the sink are protected by a special device against current leakage.

Europe. There is no single norm for all countries, each has its own rules.

  • In France, a kitchen larger than 4 m² must have at least 6 sockets, and four of them are placed above the work surface. Sockets above the sink and the hob are forbidden. The oven, dishwasher and washing machine are each connected on a separate line.
  • In Germany, a socket is not placed lower than 30 cm from the floor. Above the work area it is placed at a height of 100-130 cm.
  • In the United Kingdom, a gap of at least 10 cm is left above the countertop. Electricians usually advise 6-10 sockets per kitchen.

All countries share one thing: powerful appliances on separate lines and no sockets near water. This is exactly the principle we use to build the plan in our projects.
