Under-Cabinet Lighting Add-Ons: Dimmers, Drivers, Outlets, and Patching
The run price is the line shoppers see first. The layer behind it is everything the run connects to: the dimmer at the switch, the transformer or driver behind low-voltage fixtures, a new outlet or circuit where the kitchen prices one, the permit and inspection lines, smart controls, and patching where the wiring path crosses the backsplash. Published 2026 figures price that layer line by line, and Angi budgets $150 to $500 for the permits, electrical work, smart setup, and custom wiring around a typical project.

Dimmer, transformer, and driver lines
| Control line | Published 2026 range |
|---|---|
| Dimmer device, hardwired wall type | $30-$50 |
| Dimmer or smart switch position, fitted | $150-$300 |
| Transformer / driver, standard run | $25-$75 |
| Channels and diffusers for strip runs | $3-$8 per foot |
| Connectors, clips, and small parts | under $20 per system |
The control layer prices in two parts: the device and the fitting time at the switch position. Fixture reporting puts a hardwired wall dimmer at $30 to $50 before the junction box and wiring around it, and kitchen-lighting reporting puts a fitted dimmer or smart switch position at $150 to $300. Low-voltage runs carry a transformer or driver priced at $25 to $75 for a standard kitchen run. These lines sit on top of the run totals on the hub guide.
New outlet and new circuit lines
| Electrical line | Published 2026 range |
|---|---|
| New outlet, fitted | $156-$347, average $233 |
| Electrician visit minimum | $75-$150 |
| New dedicated circuit, labour | $550-$970 |
| New dedicated circuit, materials | $100-$150 |
| Dedicated circuit, Los Angeles-area total | $710-$870 |
Where the run prices a new power point, the lines are electrical-trade lines, not lighting lines. A new circuit is the largest add-on in this cluster, and a garage-grade 15 to 20 amp circuit is reported at $250 to $900 with an average of $650 in the same reporting. Which of these lines a project carries is set by its power scope, compared line by line on the hardwired vs. plug-in cost guide.
Permit, inspection, and smart control lines
| Layer line | Published 2026 range |
|---|---|
| Electrical permit fees | $25-$150 |
| Inspection, where priced apart | $100-$300 |
| Smart control position | $150-$300 |
| Whole add-on layer, Angi budget line | $150-$500 |
Permit and inspection lines attach to the electrical scope, not to the fixtures: a plug-in run at an existing outlet generally carries none of them, while a hardwired run with new circuit work can carry several at once. Angi rolls the whole layer together as a budgeting line of $150 to $500 for permits, electrical work, smart home setup, and custom wiring on a typical under-cabinet project. A quote that itemizes this layer can be checked against that band; a single bundled figure cannot.
Backsplash and wall patching lines
| Patching line | Published 2026 range |
|---|---|
| Wall patching and finishing | $1.50-$3.50 per square foot |
| Patching after wiring work, per opening | $50-$200 |
| Repainting | $20-$50 per hour |
The patching layer is the add-on that scales with the wiring path. Where a hardwired run crosses a finished backsplash or wall, the opening is priced to close again. Tile backsplash sections price by the tile work they need, quoted per section rather than per foot in most breakdowns. A run fitted during a remodel, while the backsplash is already open, generally carries no patching line at all -- one reason the same run prices lower inside remodel scope than as a standalone project.
Neighbour lanes carry different add-on layers
Every line on this page belongs to the connections behind one under-cabinet run. Recessed lighting carries its own add-on layer -- ceiling patching, switch work, and layout changes priced on that cluster -- and a kitchen remodel absorbs dimmer, circuit, and patching lines into whole-room electrical scope. The under-cabinet lane is the project where these lines are small, itemized, and easy to miss inside a single lump figure.
- Dimmer and driver named as separate lines
- Outlet or circuit work priced apart from the run
- Permit and inspection lines shown, or stated as not carried
- Patching rate quoted before work starts

Frequently asked questions
How much does a dimmer add to under-cabinet lighting?
The device itself is $30-$50 in fixture reporting, before the junction box and wiring around it. A fitted dimmer or smart switch position is reported at $150-$300 in kitchen-lighting reporting, which is the figure most quotes carry.
What does the transformer or driver line cost?
Fixture reporting prices a driver for a standard kitchen run at $25-$75. Strip runs priced bare add aluminum channels and diffusers at $3-$8 per foot, and connectors and mounting clips total under $20 for a complete system in the same reporting.
How much are a new outlet or a new circuit?
Outlet installation is reported at $156-$347 with an average of $233. A new dedicated circuit prices labour at $550-$970 and materials at $100-$150 on Angi figures, with Los Angeles-area totals at $710-$870.
What do permits and inspections add?
Published reporting puts electrical permit fees at $25-$150 and inspections at $100-$300 where they are priced apart. Angi budgets the whole add-on layer -- permits, electrical work, smart setup, and custom wiring -- at $150-$500 for a typical project.
Do these add-ons appear on recessed or remodel quotes?
Not as their own layer. Recessed lighting prices its ceiling patching and switch lines on its own cluster, and a kitchen remodel absorbs dimmer, circuit, and patching work into whole-room electrical scope on its own hub.
