Kitchen Lighting Guide: The Three Layers Every New Kitchen Needs

Let me start by saying something that might upset a few high street kitchen designers: if your kitchen supplier hasn’t asked you about lighting before they take your deposit, they are doing it wrong.

After 20 years supplying trade kitchens across Greater Manchester, I can tell you that lighting is the single most common regret homeowners have after a renovation. They spend £15,000 on beautiful rigid-built cabinets, solid quartz worktops, and high-end appliances, but leave the lighting as an afterthought.

The result? They end up chopping onions in their own shadow, or eating dinner under the glare of six aggressive spotlights that make the room feel like an operating theatre.

Kitchen lighting isn’t just about putting a grid of downlights in the ceiling. It’s about layering three different types of light. Here is the honest trade guide to getting it right, what it actually costs in the UK, and why you have to plan it before the plasterer arrives.

The Three Layers of Kitchen Lighting

A good kitchen lighting scheme uses three distinct layers. If you miss one, the room won’t function properly.

1. Task Lighting (The Workhorse)

Task lighting does exactly what it says on the tin: it illuminates the areas where you are actually doing things. In a kitchen, this means the worktops, the sink, and the hob.

The Reality Check: Ceiling downlights are not task lighting. If you rely on ceiling lights while standing at the worktop, your body will cast a shadow exactly where you are trying to use a sharp knife.

The best task lighting is under-cabinet LED strip lighting. It provides a continuous, shadow-free wash of light across your work surfaces. For a typical kitchen, a good electrician will charge around £150 to £500 to supply and install proper, hardwired LED strips under your wall units. It is the best money you will spend on the entire project.

2. Ambient Lighting (The Foundation)

Ambient lighting is the base layer. It is the general illumination that allows you to walk into the room, open the fridge, and see what you are doing without bumping into the island.

For modern UK kitchens, this is almost always recessed LED downlights.

The Reality Check: More is not always better. I see so many extensions where the ceiling looks like a runway because someone put 24 downlights in a grid. Instead of a grid, position your downlights where you actually need them — over the walkways, the breakfast bar, and the main floor areas. A qualified electrician will typically charge between £50 and £150 per fitting to install them. Make sure they are dimmable so you can drop the brightness in the evening.

3. Accent Lighting (The Showpiece)

Accent lighting is where you add the character. It isn’t strictly necessary for cooking, but it is what makes the kitchen look expensive.

The most common accent lighting is a row of pendant lights hung over a kitchen island or peninsula. They anchor the space and create a focal point.

The Reality Check: Don’t hang them too high. A good rule of thumb is that the bottom of the pendant should sit about 70cm above the work surface. If they are over a dining table, drop them to about 55cm above the table.

Another great accent option is plinth lighting — soft LED strips running along the kickboards at floor level. It creates a “floating” effect for the base units and acts as a brilliant, low-level nightlight if you are just coming in for a glass of water.

The Most Expensive Mistake You Can Make

The biggest mistake people make with kitchen lighting is leaving it too late.

If you wait until the cabinets are fitted to think about under-cabinet lighting, it is too late to hide the wires in the walls. You will end up having to use battery-powered puck lights (which eat batteries and look cheap) or plug-in LED strips with trailing cables.

If you want pendant lights over an island, the electrician needs to run the cables across the ceiling before the plasterboard goes up.

The Golden Rule: Your lighting plan must be finalised during the “first fix” stage — when the room is a building site and the walls are bare brick.

The Colour Temperature Trap

Here is a trade secret that ruins a lot of DIY lighting jobs: mixing colour temperatures.

Light bulbs are measured in Kelvins (K). Warm white (around 2700K to 3000K) has a yellow, cosy glow. Cool white (4000K to 5000K) is a crisp, bright, almost blue light.

If you put 4000K cool white downlights in the ceiling, but 2700K warm white strips under the cabinets, your kitchen will look terrible. The clash of colours makes the room feel disjointed.

For a modern kitchen, 4000K is usually best for task lighting because it shows the true colour of the food you are preparing. If you prefer a traditional Shaker kitchen, 3000K warm white often feels more natural. Whatever you choose, make sure every bulb in the room matches.

The SJB Verdict

At SJB Trade Kitchens, we don’t just sell you the boxes and leave you to figure the rest out. When you bring your measurements to our Oldham showroom, we will talk through exactly where your lighting needs to go.

Because our rigid-built cabinets are made to measure, we can ensure the wall units are designed to perfectly conceal your under-cabinet lighting, and we can advise your electrician exactly where the feeds need to be left during the first fix.

Don’t let lighting be an afterthought. Plan it early, layer it properly, and your kitchen will look twice as expensive when the sun goes down.
