What’s the best lighting for a kitchen extension?

There is no single light fitting that is best for every kitchen extension. For most homes, the best result comes from combining three independently controlled layers: ambient lighting for the whole room, task lighting over worktops and islands, and accent lighting that adds warmth and character.

The right combination will depend on the kitchen layout, ceiling height, natural daylight and how you use the room. Planning these details before the electrical first fix will help you avoid dark worktops, excessive glare and costly changes after the extension has been plastered.

Why kitchen extensions need a lighting plan

Kitchen extensions are often more complicated to light than standard kitchens. They may have rooflights, large glazed doors, different ceiling heights and an open-plan layout incorporating cooking, dining and social areas.

During the day, the new glazed section may be filled with natural light while the original part of the house remains comparatively dark. At night, a room that relies entirely on ceiling downlights can feel flat, clinical or unevenly lit.

A good lighting plan considers how the room will work throughout the day and during different seasons. This is particularly important in Leeds, where a kitchen extension must feel comfortable on a bright summer morning as well as a grey winter afternoon.

What are the three layers of kitchen lighting?

The best kitchen-extension lighting generally combines ambient, task and accent lighting.

Ambient lighting

Ambient lighting provides general illumination across the room. Recessed LED downlights are a popular choice because they provide a clean appearance, but they should be positioned according to the kitchen layout rather than arranged in a simple ceiling grid.

Other options include surface-mounted ceiling lights, track lighting and larger decorative fittings. Track lighting can be particularly helpful where recessed fittings are unsuitable or where homeowners want the flexibility to redirect individual lights.

The aim is to provide comfortable general illumination without filling the ceiling with unnecessary downlights.

Task lighting

Task lighting illuminates the places where you prepare food, cook, clean and serve meals.

Under-cabinet LED lighting is one of the most effective forms of kitchen task lighting because it directs light onto the worktop without creating shadows from the person standing in front of it. A continuous LED strip installed inside a diffused profile will normally create a cleaner, more even result than exposed individual LED dots.

Kitchen islands may benefit from pendants, a linear light or carefully positioned downlights. Decorative pendants can provide useful task lighting, but their output, beam direction and hanging height must be suitable for the island rather than chosen purely for appearance.

Downlights should also be positioned so that the person using the worktop does not stand between the fitting and the working surface.

Accent lighting

Accent lighting adds warmth and depth after the main cooking and cleaning activities have finished.

This could include:

• Wall lights around a dining area
• Lighting inside glazed cabinets
• Illuminated shelving
• Lighting above tall cupboards
• Subtle lighting around architectural features

Accent lighting is not essential for food preparation, but it can make an open-plan kitchen feel more inviting in the evening. It also prevents the room from relying entirely on bright overhead lighting.

How should natural daylight affect the lighting plan?

Rooflights, lanterns and large sliding or bifold doors can bring excellent daylight into a kitchen extension, but they do not remove the need for artificial lighting.

The direction the extension faces will affect how the room feels. A south-facing extension may receive strong sunlight and glare at certain times, while a north-facing extension may have softer but lower daylight levels. The original part of the kitchen can also remain darker than the newly glazed area.

Artificial lighting should balance these differences. Separately controlled and dimmable lighting zones allow homeowners to add light only where it is needed rather than switching on every fitting in the room.

The position of rooflights should also be considered before deciding where to place downlights or pendants. Leaving these decisions until the electrical installation has begun can result in awkward spacing or fittings that do not align with the island and kitchen units.

What colour temperature is best for a kitchen?

Colour temperature describes whether white light appears warm, neutral or cool. It is measured in kelvins, shown as “K” on the product packaging.

For many open-plan kitchen extensions, 3000K provides a good balance: it is warm enough for dining while remaining clear and practical for food preparation. Homeowners wanting a cosier appearance may prefer 2700K, while 4000K creates a brighter and more neutral effect.

Consistency is important. Mixing noticeably different colour temperatures in the same open space can make the lighting look patchy or unplanned. If different temperatures are used, they should form deliberate, visually separate zones.

Colour rendering also matters. LEDs with a colour rendering index, or CRI, of 90 or above can help food, worktops, cabinets and finishes appear more natural.

It is worth viewing sample fittings in the kitchen before committing to every light, particularly when the room includes strongly coloured cabinets, natural stone or timber finishes.

Do kitchen lights need to be dimmable?

Dimmable lighting is highly beneficial in a kitchen extension because the same room may be used for cooking, working, eating and entertaining.

Rather than placing every light on one switch, consider separate controls for:

• General ceiling lighting
• Under-cabinet task lighting
• Island pendants
• Dining-area lighting
• Accent or shelf lighting

This allows you to use bright task lighting while preparing a meal and then reduce the general lighting for dining or relaxing.

Traditional wall dimmers are often the simplest option. Smart lighting can add app controls, timers and preset scenes, but it must be selected carefully to avoid unnecessary complexity.

Whichever system you choose, the LED fittings, drivers and dimmers must be compatible. Poorly matched components can cause flickering, buzzing, restricted dimming or lights that do not switch off properly.

Which type of kitchen lighting is best?

Each type of light has a different role:

Recessed downlights

Downlights create a clean, unobtrusive appearance and can provide effective ambient or targeted task lighting. However, using too many can make the kitchen feel overly bright and clinical.

Their position, beam angle and light output should be selected according to the ceiling height, worktop locations and kitchen layout.

Track and surface-mounted lighting

Track lighting allows individual fittings to be directed towards different parts of the kitchen and may be useful where ceiling construction makes recessed lighting difficult.

It is more visible than downlighting, so it should suit the style of the room.

Pendant lights

Pendants can create a strong visual feature above an island or dining table. They can also provide useful focused lighting if the fittings produce enough light and direct it appropriately.

The height should be chosen according to the ceiling, the size of the fitting and the sightlines across the room. As a general starting point, pendants are often positioned approximately 75–90cm above an island, but this should be adjusted for the specific room and fitting.

Under-cabinet lighting

Under-cabinet LEDs are usually the most effective way to illuminate worktops beneath wall units. They help reduce shadows and make food preparation and cleaning easier.

The LED driver should remain accessible for future maintenance rather than being permanently concealed behind plaster or fixed joinery.

Wall and shelf lighting

Wall lights and illuminated shelving provide depth and atmosphere. They are particularly effective in dining or seating areas where bright task lighting is unnecessary.

When should kitchen-extension lighting be planned?

Lighting should be planned once the kitchen layout is sufficiently developed and before the electrical first fix.

The electrician will need accurate information about:

• The position and dimensions of the island
• Wall and tall-unit locations
• Worktop and cabinet heights
• Appliance positions
• Extractor fans or cooker hoods
• Rooflights and ceiling features
• Dining-table and furniture locations
• Entry points and preferred switch positions

The kitchen supplier, builder and electrician should coordinate these details. Even a small change to the island or cabinetry can affect whether a pendant is centred correctly or whether a downlight casts a shadow over the worktop.

Switching should also be considered early. In a room with several entrances, two-way or multi-way switching may make the space much easier to use.

Common kitchen-lighting mistakes

Some of the most common problems include:

• Installing too many downlights
• Arranging downlights in a ceiling grid without considering the worktops
• Forgetting under-cabinet task lighting
• Placing lights behind the person using the work surface
• Mixing incompatible colour temperatures
• Choosing LEDs with poor colour rendering
• Using non-dimmable or incompatible LED components
• Hanging pendants before confirming the island position
• Forgetting the extractor hood or rooflight location
• Not separating the lighting into different control zones
• Concealing LED drivers where they cannot be maintained
• Leaving lighting decisions until after first fix

Early planning makes these problems much easier—and usually less expensive—to avoid.

What should homeowners know about electrical safety?

Kitchen lighting must be suitable for the conditions in each location. Fittings exposed to moisture, heat, steam or frequent cleaning should be selected and installed in accordance with the manufacturer’s instructions.

Unlike bathrooms, kitchens do not have the same prescribed electrical zones around sinks. The appropriate fitting will depend on its position and the environmental conditions rather than applying one universal IP rating throughout the room.

Recessed downlights must also be suitable for the ceiling construction. Required clearances from insulation must be maintained unless the fitting is specifically approved for insulation contact. Fire-rated fittings should be used where necessary to maintain the fire performance of the ceiling.

New and altered domestic electrical installations must comply with Part P of the Building Regulations and current UK electrical safety requirements. Where the work is notifiable, the homeowner should receive the appropriate Building Regulations documentation, alongside relevant electrical certification.

Frequently asked questions

How many downlights does a kitchen extension need?

There is no standard number that works for every kitchen. The correct quantity depends on the room dimensions, ceiling height, beam angle, light output, cabinetry and other lighting sources. The layout should be based on where light is required rather than using a fixed spacing rule.

Is warm white or cool white better for a kitchen?

Many homeowners choose 3000K because it works well for both preparation and dining. A 4000K light creates a brighter, more neutral appearance, while 2700K feels warmer. Consistency and good colour rendering are often more important than selecting one supposedly “best” temperature.

Are pendant lights enough for a kitchen island?

Pendants may provide effective island lighting if they have suitable output and direct light onto the surface. Decorative pendants with low-output lamps may need to be supported by carefully positioned downlights.

Is under-cabinet lighting necessary?

It is not compulsory, but it is one of the most useful additions to a kitchen. Wall cabinets can block ceiling light, leaving worktops in shadow. Under-cabinet lighting directs light exactly where food preparation and cleaning take place.

Can kitchen lighting be changed after the extension is finished?

Some fittings can be replaced later, but adding new lighting positions, switches or circuits after plastering and decorating may involve disruption and additional expense. It is usually better to plan the complete lighting and control layout before first fix.

Summary

The best lighting for a kitchen extension combines ambient, task and accent lighting, with each layer controlled separately. The design should follow the kitchen units, island, ceiling height and glazing rather than relying on a standard grid of downlights.

Plan the lighting after the kitchen layout has been developed but before electrical first fix. Keep colour temperature consistent, choose good-quality compatible LED components and make sure fittings are appropriate for their location and ceiling construction.

A carefully planned installation will give you a kitchen that feels bright and practical while cooking, but warm and comfortable when it is time to eat and relax.
