How to Hide Under Cabinet Lighting Wires and LED Drivers
Under cabinet lights can make a kitchen feel beautifully finished, but exposed wires and a driver sitting on the worktop can spoil the effect. The good news is that with a little planning, most of the cabling for a suitable low-voltage kitchen lighting system can be kept discreetly out of sight.
This guide explains how to hide under cabinet lighting wires, where an LED driver can go, and what to consider before drilling holes or fitting the lights. We also explain how the Loops 24V Lighting Project Builder can help you plan cable lengths, drivers and separate lighting areas together.
Quick answer
For many fitted kitchens, a neat approach is to route the low-voltage light cables along the underside or rear of the wall cabinets, take them through a carefully positioned, protected cable opening where suitable, and connect them to a compatible driver in an accessible, ventilated position. Use cable clips or a suitable small trunking to tidy visible runs. Always follow the exact light and driver installation instructions.
Why should you plan the wiring before installing the lights?
It is easy to choose a fitting based on how it looks from the front, only to discover that its cable exits in an awkward position. Cabinet joints, shelves, hinges, corner units and the location of the power supply can all affect the final installation.
Before fixing anything, decide where each light will sit, where its cable will run and where the driver will remain accessible. That makes it much easier to achieve the clean, cable-free appearance you want on the worktop side of the cabinets.
Six practical ways to keep under cabinet lighting cables discreet
1. Run low-voltage cables along the rear of the cabinet underside
On a suitable cabinet, cables can often follow the back edge underneath the unit, where they are less noticeable from normal standing height. Neatly sized cable clips or compatible mini trunking can help hold the run in place. Check clearances and do not leave leads hanging where they might be caught or pulled.
2. Use an existing concealed void where appropriate
Some kitchens have an accessible space above or behind cabinets through which a suitable cable can be routed discreetly. Only use a route that is suitable for the cable, keeps it protected, and allows the required access to the driver and connections. Do not trap a lead behind a cabinet or assume an enclosed void provides adequate driver ventilation.
3. Take the cable through a carefully planned cabinet opening
A suitable cable opening near the back of a cabinet can take the light lead out of view. Before drilling, check for concealed electrical cables, pipes and cabinet hardware. Protect cables from sharp edges with an appropriate grommet or bush, and make sure the connector and cable can pass through without damage. Follow the fitting maker's instructions and avoid drilling structural or unsuitable cabinet areas.
4. Use the cabinet front lip or a suitable lighting pelmet
If the cabinet design has a small front lip or pelmet, it may help shield a surface mounted light and its nearby cable from view. Plan the light position for useful worktop illumination first; hiding the fitting completely is not worth creating poor or uneven lighting.
5. Keep cables clear of moving parts and hot or wet areas
Route cables away from hinges, drawer runners, sharp metal edges, hob heat, hot pipework and places where water may reach the fittings or connectors. Check the light's IP rating and the manufacturer's siting restrictions, especially around sinks and cooking appliances. Never rely on a decorative cable cover to make an unsuitable location safe.
6. Keep access to connectors and the driver
A hidden cable is helpful; an unreachable power supply is not. Plan enough access for inspection, maintenance and replacement, and avoid tightly enclosing or covering the driver. Its exact clearances, orientation and ventilation requirements must come from the product instructions.
Where is the best place to hide an LED driver?
The driver converts the incoming supply into the output needed by the lights. For the Loops 24V system, a compatible driver supplies 24V DC to the chosen fittings. It needs a suitable mains supply, the required ventilation and a location that remains accessible.
Depending on the particular kitchen and the driver's instructions, an accessible space above the wall cabinets, or a suitable service space within a cabinet, may be worth considering. However, neither is automatically suitable. The location must be evaluated for heat, moisture, clearance, ventilation, load, secure positioning and safe connections.
Do not bury a driver behind permanent tiling or plasterboard, surround it with insulation, cover its ventilation openings, or place it in a position where it cannot be safely serviced.
The key distinction: low-voltage leads vs mains connections
Tidy routes for the low-voltage lighting cables are not the same as installing or altering the mains supply to the driver. Use the manufacturer's supported plug-in connection where appropriate. Any work on fixed mains wiring or mains connectors should be planned and carried out by a suitably qualified electrician.
If you are unsure which driver the lights require, our guide to choosing an LED driver for under cabinet lights explains voltage, wattage and connector requirements in more detail.
How long are the light cables — and do I need extensions?
Cable lengths differ between fittings and variants, so check the exact product before fixing your driver location. For example, several Loops 24V styles have a 2m lead, while the fixed-white Elara version has a 1.5m lead. That difference can matter if your planned driver sits on top of a cabinet or across a corner.
Within the supported Loops 24V system, the Project Builder offers compatible 2m and 5m extension leads where needed. It also helps you plan their quantity. Do not assume extensions are suitable for other lighting systems, join leads together arbitrarily or exceed the supported connection and cable-length rules.
Measure the actual cable route, not simply the straight-line distance between the light and the driver. Allow for cabinet corners and a neat route without stretching or trapping any connectors.
A simple wiring layout to plan before you start
For a compatible low-voltage lighting system, the practical route is usually:
01
Under cabinet lights
Choose the fitting positions first.
02
Concealed cable route
Protect and secure each lead.
03
Matched driver
Keep the driver accessible and suitably ventilated.
In the Loops 24V system, the driver and any required distribution blocks are matched to the number and type of lights in the zone. Those blocks give the system the necessary connection points, but they do not increase a driver's wattage capacity.
What if you have an L-shaped kitchen or separate worktop areas?
There is no need to force every cabinet into one long cable route. Start by identifying which lights should operate together.
For example, you might want the preparation area to switch on independently of the lights under cabinets on the other side of the kitchen. In the Loops Project Builder, you can create separate lighting zones, each with its own matched driver and compatible control arrangement. This can simplify planning where separate worktop runs need different behaviour.
Our light quantity guide and positioning guide can help you decide where the fittings belong before you plan the cable route.
Common cable-hiding mistakes to avoid
- Choosing the driver position too early. Check light positions and cable reach first.
- Trapping cables behind cabinets or through bare, sharp-edged holes. Route and protect them appropriately.
- Hiding the driver so completely that it cannot be reached or ventilated. Access and manufacturer-required clearances still matter.
- Using unrelated leads or splitters. Only use compatible components within the system's supported limits.
- Assuming a standard wall dimmer will work. The standard Loops 24V drivers are not intended for mains wall dimming; choose compatible controls in the Builder.
- Drilling without checking what is behind the cabinet. Check the area for concealed services and get professional advice when unsure.

Frequently asked questions
Can I hide LED lighting wires inside the kitchen cabinets?
A suitable protected low-voltage cable route may pass through a cabinet, depending on the cabinet design and product instructions. Protect the cable from wear and sharp edges, keep it away from hinges and stored objects that could damage it, and do not trap connectors.
Can I place an LED driver on top of the kitchen cabinets?
It can be a practical option for some products and layouts, but only when the manufacturer's mounting, ventilation, access and electrical requirements are met. It is not automatically the correct location for every driver.
Can I put the LED driver behind the splashback or plasterboard?
Do not conceal a serviceable driver behind permanent finishes where access or ventilation is lost. Plan an appropriate accessible position instead.
Are the leads on all Loops under cabinet lights the same length?
No. They vary by fitting and sometimes by version. Always check the specific light before planning cable routes, especially where fixed-white and colour-changing versions differ.
Do I need one driver for every under cabinet light?
Not normally. In the Loops 24V system, several compatible lights can share one correctly matched driver within a single zone, subject to its load and connection limits. Each zone in the Builder uses one matched driver.
Should an electrician install my under cabinet lights?
For any new or altered fixed mains wiring, use a suitably qualified electrician. If your setup uses a supported plug-in power connection, still follow the supplied installation instructions and take appropriate care when routing and securing the lights and low-voltage cables.
Make the lighting visible — not the wiring
A tidy result starts with planning: choose the right fitting locations, work out how the cables can reach a suitable accessible driver, then select compatible accessories. The Loops Lighting Project Builder helps bring the lights, driver, controls and zones together so you can plan the whole setup rather than buying separate parts by guesswork.
This guide is for planning purposes, not a substitute for a product-specific installation manual or electrical design. The suggested Builder link opens the Project Builder on the 24V collection page. Electrical work and all component positioning must follow current product instructions and applicable safety requirements.
