Kitchen Lighting Ideas: Layers, Worktops, Zones and What Needs an Electrician

What you need before you start

These kitchen lighting ideas are built around one plan: light the jobs you do, in layers, and keep each layer on its own switch. This guide shows how to divide the kitchen into zones, choose lights for work surfaces, islands and tables, pick colour and brightness, and know when to call an electrician.

You need a tape measure, a sketch of the kitchen, a pencil and a notepad. Mark the worktops, hob, sink, any island or table, the windows and the existing light points.

Mains electrical work is for a qualified electrician. We describe what the rules say so you can brief the electrician well, but we do not give wiring instructions. Everything in the “no-mains” step needs no wiring at all.

For the maths behind brightness see how many lumens and what colour temperature for each room, and for the general idea of layers see layered lighting for a living room.

Step 1: map your kitchen into zones

Start with the jobs, not the fittings. Most kitchens have four working zones, and the plan below shows them. This is our own way of dividing the room, not a standard.

1. Prepare. The worktop where you chop and mix. It needs the most light, with no shadow.
2. Cook. The hob and oven. It needs clear light and sensible distance from heat and steam.
3. Wash. The sink and drainer, often under a window.
4. Gather. An island, breakfast bar or table, where mood matters more than brightness.

Add the walkway between them. Write beside each zone what light it has today: window, ceiling light, nothing. The gaps are your shopping list.

Step 2: build three layers

Kitchen designers talk about three layers of light. Harvey Jones describes them as ambient, task and accent: ambient is the base layer from recessed downlights, flush or semi-flush fittings or dimmable LED panels; task is the most important and includes under-cabinet strips, pendants over an island and spotlights over the sink and hob; accent adds atmosphere with in-cabinet lights, plinth strips, over-cabinet uplighting and wall lights.^[1] Downlights Direct makes the same three-way split.^[2]

Why layers? One bright ceiling light is flat and casts your own shadow onto the worktop. Layers let you work in clear light and then drop to a soft evening glow. Harvey Jones suggests putting the task lights on separate switches from the ambient lighting and dimming the ceiling lights to around 30 per cent when entertaining.^[1] A retailer’s blog and a kitchen maker are not neutral sources, but on this point they agree with the wider lighting guidance on balance, which we cover in Step 4.

Step 3: light the work surface

The prepare zone is where lighting fails most often. Standing at the worktop, your body blocks the ceiling light and throws a shadow on your hands.

Under-cabinet lights. Mount them toward the front edge of the cabinet underside, so they light the worktop and not just the splashback. Harvey Jones says to mount strips toward the front;^[1] Simple Lighting says fitting near the front edge removes the shadow your body casts, while strips set too far back leave the splashback bright and the work surface partly shaded.^[3] Downlights Direct says under-cabinet lights improve visibility by reducing shadows and glare.^[2]

How bright? Simple Lighting gives around 500 to 1,000 lumens per metre as a general target for LED strip task lighting, depending on the surface and the brightness you want, and notes that dark worktops absorb more light and may need brighter lighting.^[3] That is a retailer’s figure; treat it as a starting point.

Watch for reflections. HSE’s lighting guide describes veiling reflections as high-luminance reflections over the task that cut contrast, and suggests a matt surface or moving the bright source, checked with a mirror from the worker’s viewpoint.^[4] On a glossy worktop, choose diffused strips or a covered profile so you see a soft line of light and not the bare chips.

The animation below shows the difference a few centimetres make.

Step 4: set the ceiling light and the overall level

The ceiling layer should be bright enough to see the room and not so bright that the worktop light adds nothing. There is no legal lux level for a home kitchen. HSE’s workplace guide gives 200 lux average with 100 lux minimum for work requiring perception of detail, and 500 lux average for fine detail such as drawing offices.^[4] Ledkia, a lighting retailer, gives indicative home values of 200 lux for general kitchen lighting and 500 lux for the worktop, noting that the workplace standard does not formally apply to homes.^[5] Use them as a rough guide.

HSE also says that a task lit separately at 500 lux should not sit in surroundings much below about a fifth of that, a 5:1 ratio.^[4] In a kitchen that means: if the worktop is bright, keep the room lit too. Our rule of thumb is to size the ceiling layer for the general level and let the task layer do the rest.

Where you can, keep bare lamps out of direct view. HSE advises avoiding direct view of lamps near the line of sight by shielding them or keeping them out of the exclusion zone.^[4] Recessed fittings with a deep recess or a diffuser do this well.

Step 5: pendants over islands and tables

Harvey Jones suggests two to three pendants over an island, hung 75–90 cm above the worktop, with enough space between them to avoid crowding and not blocking sightlines across the room; over a dining table it gives 70–85 cm.^[1] Those are one designer’s numbers, and ceiling height and the height of the people using the room will change them, so hold a pendant up with tape before you commit.

Choose pendants with shades that hide the bulb, since the lamp should be out of your direct view. Downlights Direct suggests choosing a style to match the kitchen and notes that pendants highlight an island or dining table.^[2] If the pendants go over a hob, check the fitting is suitable for the heat and grease, and follow the maker’s instructions.

Step 6: colour temperature, colour rendering and dimming

Colour matters in a kitchen because you judge food by its colour. Harvey Jones suggests 2700–3000 K for warm, cosy light in dining and traditional kitchens, 3500 K as a balanced, natural choice for most kitchens, and 4000 K for brighter light in prep areas and contemporary spaces, with warmer light in social zones and cooler light in task zones.^[1] Simple Lighting calls about 4000 K the safer colour and says mixed-style kitchens often suit 3000–4000 K, and advises matching under-cabinet lights to the ceiling lights where possible and avoiding mixing warm and cool tones.^[3]

The Energy Saving Trust describes warm white as 2700–3000 K for most general household lighting and says cool white at 4000–4500 K may suit bathrooms and maybe kitchens. It also says a colour rendering index of 80 or more is good for most household tasks.^[6] Our rule of thumb is to look for CRI 90 where you prep food, but that is our preference, not a cited figure.

On dimming, the Energy Saving Trust warns that not all LED bulbs work with dimmers, that a dimmer not designed for LEDs may not work properly, and that you may need to consult an electrician.^[6] Buy lights and dimmers as a matching set.

Zones and IP ratings: what applies in a kitchen?

People often mix up kitchens with bathrooms here. The IP code is a two-digit rating: the first digit (0–6) is protection against solid objects such as dust and the second (0–9) is protection against moisture.^[7] The detailed zone rules, such as zone 1 and zone 2 distances around a bath or shower, are for bathrooms.^[7] Our bathroom lighting zones guide covers them in full.

The building regulations guidance on electrical safety defines “special locations” as including a room with a bath or shower and a room with a swimming pool or sauna heater; kitchens are not on that list.^[8] Because the sources we read give no kitchen zone map, we treat the following as our rule of thumb: choose a splash-resistant fitting, such as IP44, for lights directly above or very close to the sink and hob, and check the maker’s instructions for cooker-hood lights and anything near heat. This is a precaution, not a regulation we can quote for kitchens.

If you are not sure what rating a fitting needs, ask the electrician who is installing it. For a plug-in or battery light that sits away from water, ratings matter far less than sensible placement.

Which kitchen jobs need an electrician?

Fixed lighting runs on mains wiring, and mains work should be done by a qualified electrician. Here is what the official guidance says, so you know how to brief one.

• New circuits and consumer units. Approved Document P lists as notifiable the installation of a new circuit, replacement of a consumer unit, and any addition or alteration to existing circuits in a special location.^[8]
• Fixed kitchen equipment. It says fixed kitchen equipment is in scope but is notifiable only if it involves that listed work, giving a built-in cooker as an example, and applies the same test to prefabricated, modular kitchen lighting systems.^[8]
• Other electrical work. Work that is not notifiable must still be designed, installed, inspected, tested and certificated to BS 7671.^[8]
• Certification. Notifiable work can be self-certified by a registered competent person, or checked by building control.^[8] GOV.UK says you do not need to apply for approval yourself if you use someone registered with a competent person scheme.^[9]

Simple Lighting, a lighting retailer, likewise advises hiring a qualified electrician for hardwired mains installations.^[3] Ask any electrician to confirm what is notifiable for your job; we are not giving legal advice.

Step 7: no-mains options

You can improve a kitchen without touching the wiring.

• Plug-in under-cabinet kits. A complete kit with its own plug and driver, bought from a reputable seller, needs only a socket. Keep the lead tidy and away from hot surfaces; the Cleveland Fire Brigade advises keeping electrical cables away from hot surfaces and not overloading plugs.^[10]
• Battery or rechargeable lights. Stick-on or magnetic lights suit a pantry, an alcove or a single worktop. Check how often you will be changing batteries.
• Battery wall lights. A battery wall light by a dining nook adds the accent layer with no cable. Flare’s plaster wall lights come as battery or mains versions; see the pieces below and our guide to plug-in, battery or hardwired wall lights.

For rented kitchens, plug-in and battery options also leave no marks: see wall lights for rented flats.

Worked example: a 4 m by 3 m kitchen

The dimensions are invented for the example. The kitchen is 4 m by 3 m, which is 12 square metres, with a run of 2.4 m of worktop under wall cabinets, a hob on the same wall and a 1.8 m table at one end.

1. Ambient. Use the 200 lux guide:^[5] 200 lux over 12 square metres is 2,400 lumens landing on surfaces. Real fittings and rooms lose light, so plan comfortably above that and put the layer on a dimmer.
2. Task. A 2.4 m strip at 500–1,000 lumens per metre gives about 1,200–2,400 lumens,^[3] mounted at the front edge of the cabinets, on its own switch.
3. Table. One shaded pendant at 70–85 cm above the table top,^[1] on a dimmer.
4. Accent. A battery wall light by the table, no wiring needed.
5. Colour. Pick one temperature, about 3000 K, so all layers match,^[3] and CRI 80 or more.^[6]
6. Electrician. The strip, ambient layer and dimmers go in the electrician’s brief. Wiring for any new circuit is their call.^[8]

Common mistakes

• One central light only. It leaves shadows on the worktop and no evening mood.^[1]
• Under-cabinet strips at the back. They light the splashback, not your work.^[3]
• Mixing warm and cool bulbs. It looks patchy.^[3]
• Dimmer and bulb mismatch. Buy them as a pair.^[6]
• Glossy worktop, bare chips. Veiling reflections; use diffused light.^[4]
• Lead over a hob. Keep cables away from hot surfaces.^[10]
• Assuming kitchens have bathroom-style zones. Check with the electrician.^[8]

Fire sense in a kitchen

Kitchens are where fires start. Cleveland Fire Brigade says over half of accidental home fires start in the kitchen. It advises keeping tea towels, cloths and curtains away from cookers, keeping cables away from hot surfaces, and following manufacturers’ instructions without overloading plugs.^[10] Position lights so that no shade, fabric or cable sits over a hob, and leave mains work to a qualified electrician.

Frequently asked questions

What is the best lighting for a kitchen?

Use three layers: ambient from the ceiling, task light over the worktops, and accent light for mood, each on its own switch. Put under-cabinet strips toward the front edge so your body does not shadow the work surface.

Where should under-cabinet lights go?

Toward the front edge of the cabinet underside. Kitchen makers and lighting retailers say this lights the worktop and removes the shadow of your body, while strips at the back mostly light the splashback.

How high should pendants hang over a kitchen island?

Harvey Jones suggests 75–90 cm above the worktop, with two to three pendants over an island. Hold one up before fixing, because ceiling height and user height change the right figure.

What colour temperature is best for a kitchen?

A balanced range is about 3000–4000 K. Harvey Jones suggests 2700–3000 K for dining, 3500 K for most kitchens and 4000 K for prep. Match under-cabinet and ceiling lights so the colours do not clash.

Do kitchens need IP-rated lights?

The bathroom zone rules do not apply to kitchens, and the building regulations guidance lists bath and shower rooms as special locations, not kitchens. Our rule of thumb is a splash-resistant fitting such as IP44 near the sink and hob; ask your electrician.

Can I fit kitchen lights myself?

Plug-in kits and battery lights need no wiring. Fixed lighting that needs new cable, a new circuit or a consumer unit change is mains work for a qualified electrician, and some of it is notifiable under Approved Document P.

How bright should kitchen lighting be?

There is no legal lux level for homes. HSE workplace guidance gives 200 lux average for detailed work, and a lighting retailer suggests about 200 lux general and 500 lux on the worktop. Use these as a guide and add dimming.

Is LED strip lighting safe under cabinets?

Well-made kits from reputable sellers are widely used. Keep cables and drivers away from hot surfaces, do not overload plugs, and use a qualified electrician for any hardwired installation.
