Under cabinet lighting transforms a dim kitchen workspace into a well-lit prep zone while adding subtle ambiance. But before shopping for fixtures, homeowners need a clear picture of installation costs, which vary widely based on lighting type, labor method, and how the existing kitchen is wired. A basic plug-in LED strip might cost under $50 total, while hardwired puck lights across a full run of cabinets can exceed $800 once electrician fees are factored in. This guide breaks down current pricing, compares fixture options, and explains when DIY makes sense versus calling in a pro.
Key Takeaways
- The cost to install under cabinet lighting ranges from $200 to $700 for a standard 10- to 15-foot run, with DIY plug-in systems costing $100–$300 and professional hardwired setups reaching $500–$1,200.
- LED strip lights offer the most affordable option at $30–$100 per roll with DIY installation under $150, while puck lights and linear bars provide flexible mid-range alternatives from $150–$300 for DIY projects.
- New circuit installation adds $300–$800 to the total cost and is the largest variable factor, particularly in older homes lacking GFCI-protected outlets that meet current electrical codes.
- DIY installation saves 50% or more for plug-in and low-voltage systems if existing outlets are available, but professional installation is worth the $150–$500 labor cost when hardwiring or code compliance is required.
- Regional electrician rates significantly impact final pricing, ranging from $60–$90 per hour in the Midwest and Southeast to $100–$150 in coastal cities, making the same project cost 40–75% more in certain areas.
- Hardwired systems provide cleaner aesthetics and smart home integration but demand licensed electrician expertise, while plug-in fixtures prioritize affordability and ease at the cost of visible cords and accessibility limitations.
Average Cost to Install Under Cabinet Lighting
As of April 2026, the typical cost to install under cabinet lighting ranges from $200 to $700 for a standard 10- to 15-foot run of cabinets, including materials and labor. DIY installations with plug-in fixtures land on the lower end, often $100 to $300, while professionally hardwired systems push toward $500 to $1,200 depending on complexity and fixture choice.
Breaking it down further:
- Materials (fixtures and hardware): $80 to $400
- Electrician labor: $150 to $500 for hardwired installations (typically 2 to 4 hours at $75 to $125 per hour)
- Dimmer switches and controls: $25 to $150
- Wire and connectors (if needed): $20 to $60
Plug-in systems eliminate electrician costs entirely but require accessible outlets, which not all kitchens have under the cabinet line. Hardwired setups look cleaner, no visible cords, and integrate with existing switches, but they demand electrical experience or a licensed electrician, especially if new circuits are involved. New circuit installation can add $300 to $800 to the project, particularly in older homes lacking GFCI-protected kitchen outlets that meet current NEC (National Electrical Code) standards.
Cost Breakdown by Lighting Type
LED Strip Lights
LED strip lights (also called tape lights) offer the most affordable and flexible option. A quality 16-foot roll costs $30 to $100, with budget models dipping to $15 but often producing uneven light or failing within a year. Most strips come with adhesive backing and plug-in adapters, making them DIY-friendly.
- Total DIY cost: $50 to $150 for materials (strips, connectors, mounting clips)
- Professional installation: $200 to $400 if hardwired with in-wall power supply and dimmer
Strips work best for continuous runs and provide diffused, even light. They require a flat mounting surface, usually the bottom front rail of the cabinet, and should be installed 1 to 2 inches from the front edge to avoid glare on countertops. Look for strips rated at 2,700K to 3,000K color temperature for warm task lighting and a CRI (Color Rendering Index) above 90 for accurate color when prepping food.
Puck Lights
Puck lights are small, disc-shaped fixtures spaced every 12 to 18 inches along the cabinet run. Battery-operated versions cost $8 to $20 per puck, while hardwired halogen or LED pucks range from $15 to $50 each.
- Total DIY cost (battery): $50 to $120 for six pucks and adhesive mounts
- Total DIY cost (plug-in low-voltage): $100 to $200 including transformer and linking cables
- Professional installation (hardwired 120V): $350 to $650 for six to eight pucks, wiring, and switch integration
Pucks create pools of light rather than uniform coverage, which some homeowners prefer for accent lighting. They’re easier to retrofit into tight spaces than strips, but halogen pucks generate significant heat, a concern if they’re mounted near stored plastics or medications. LED pucks stay cooler and last 25,000+ hours versus 2,000 for halogen.
Linear Bar Lights
Linear bar lights (rigid LED fixtures) sit between strips and pucks in cost and coverage. Individual bars come in standard lengths, 12″, 18″, 24″, and 36″, and link together with snap connectors.
- Cost per fixture: $25 to $80 depending on length and quality
- Total DIY cost (plug-in): $150 to $300 for three to five bars, connectors, and power supply
- Professional installation (hardwired): $400 to $750 for a full kitchen run with dimmer and wall switch
Bars deliver more uniform light than pucks without the visible diodes sometimes seen in cheaper LED strips. They mount with screws or clips, making alignment easier on cabinets that aren’t perfectly level. Most models are linkable, meaning one power source can drive multiple bars, helpful when outlets are scarce. Higher-end bars include diffusers to soften LED hotspots and offer tunable white (adjustable color temperature from 2,700K to 5,000K).
Factors That Affect Installation Costs
Several variables push installation costs above or below the averages:
Existing electrical access. Kitchens with a nearby outlet or existing under-cabinet wiring keep costs low. Adding a new circuit from the breaker panel, common in kitchens built before the 1990s, requires running 12/2 or 14/2 NM cable through walls or attics, adding $300 to $800 in labor and materials. GFCI protection is required for all kitchen countertop circuits per NEC 210.8, which may mean upgrading the breaker or installing GFCI outlets.
Cabinet material and construction. Solid wood cabinets accept screws easily and hide wiring channels. Particleboard or frameless Euro-style cabinets may need adhesive mounts or external wire channels, complicating clean installations. Inset cabinets (where doors sit flush with the frame) leave less room for fixture mounting than overlay styles.
Dimmer and control complexity. A basic rotary dimmer costs $15 to $30. Smart dimmers compatible with Alexa, Google Home, or HomeKit range from $50 to $150 and may require a neutral wire, not always present in older switch boxes. Motion sensors or time-of-day controls add another $30 to $80 per zone.
Tile backsplash or existing finishes. Hardwiring through a tile backsplash usually means drilling through grout lines or removing tiles to fish wire, adding an hour or more of labor. Some electricians charge extra for delicate work around natural stone or glass tile.
Permit requirements. Most jurisdictions don’t require permits for low-voltage (12V or 24V) plug-in lighting. Hardwired 120V installations that add new circuits or modify existing branch wiring typically do, especially if walls are opened. Permit fees run $50 to $150, and inspections add time. Always check local codes, unpermitted electrical work can complicate home sales or insurance claims.
Regional labor rates. Electrician rates vary significantly: $60 to $90 per hour in the Southeast and Midwest, $100 to $150 in coastal metros and the Northeast. A job quoted at $400 in Atlanta might cost $700 in San Francisco for identical scope.
DIY vs. Professional Installation: Which Costs Less?
DIY installation saves the most money for plug-in or low-voltage systems. A homeowner comfortable with basic tools can install LED strips or battery pucks in one to three hours, keeping total costs under $200. Required tools are minimal: measuring tape, level, drill with bits, wire strippers (for low-voltage connections), and possibly a stud finder if anchoring into drywall behind cabinets.
Key DIY advantages:
- Full control over fixture placement and spacing
- No scheduling delays or hourly labor charges
- Easy to expand or modify later
DIY challenges:
- Plug-in cords may be visible unless routed carefully
- Low-voltage transformers and linking cables can clutter cabinet interiors
- Uneven light output if fixtures aren’t aligned properly
Professional installation makes sense for hardwired systems, especially when:
- The project requires new circuits or modifications inside the breaker panel
- Cabinets are already installed and wiring must be fished through finished walls
- The homeowner wants integration with existing three-way switches or smart home systems
- Local codes require licensed electrician sign-off for inspections
Electricians bring speed and code compliance. What takes a DIYer a full Saturday, measuring, drilling, wiring, testing, a pro completes in two to four hours, with cleaner wire management and proper strain relief on connections. The labor premium ($150 to $500) buys peace of mind, particularly in homes with older wiring where mistakes can trip breakers or create fire hazards.
Hybrid approach: Some homeowners install plug-in fixtures themselves, then hire an electrician for one to two hours ($100 to $250) to add a dedicated outlet or hardwire a single power supply, hiding cords while keeping labor costs reasonable.
Bottom line: if outlets exist near the cabinet run and the homeowner is comfortable with basic electrical connections, DIY cuts costs by 50% or more. If new circuits, wall fishing, or permit-required work is involved, professional installation often costs less in the long run than troubleshooting DIY mistakes or failing inspection.
