Generally, no. If by “outlet” you mean a standard wall receptacle, or a UK wall socket, you should not use a normal in-wall lighting dimmer to control it.
A lighting dimmer is designed for specific types of lighting loads. A general-purpose socket, on the other hand, could be used for anything from a table lamp to a television, charger or vacuum cleaner. Once a socket is connected to a dimmer, there is no reliable way to know whether the next device plugged into it is suitable for dimmed power.
For a plug-in lamp, use a plug-in lamp dimmer designed for compatible dimmable lighting. For permanently wired lighting, use a correctly rated hardwired dimmer.

Why Shouldn’t a Standard Dimmer Control a General-Purpose Outlet?
The problem is not the socket itself, but the load connected to it.
Lighting dimmers are designed around the characteristics of particular lamps and drivers. Depending on the product, they may use leading-edge or trailing-edge control, and manufacturers specify which lighting loads and operating conditions are supported.
A general-purpose socket does not provide that certainty. A compatible lamp could be unplugged one day and replaced with a charger, television or other appliance that was never designed to receive dimmed power.
When Is a Hardwired Dimmer the Right Choice?
A hardwired dimmer is appropriate when the circuit permanently controls lighting and the lamps or drivers are designed to be dimmed.
Before choosing one, check the lighting type, total load, dimming method, switching arrangement and installation requirements. With LED lighting in particular, both the lamp and dimmer need to be compatible. Simply having “dimmable” printed on both products does not guarantee good performance.
The dimmer's load rating matters too. Minimum and maximum loads, dimming mode and multi-gang installation can all affect the usable rating, so the specification for the exact product should be followed. For UK retrofits, the available wall-box depth is also worth checking before choosing a smart dimmer.
Using a Repenic Dimmer on a Hardwired Lighting Circuit
The Repenic Zigbee Smart Dimmer is designed for UK two-wire lighting circuits and does not require a neutral wire at the switch. It supports compatible dimmable lighting with leading-edge and trailing-edge control, while a compatible Zigbee gateway adds smart functions such as app control, schedules, scenes and automation.

FAQs
Can I put a standard dimmer on a switched outlet?
A switched socket can be designed for on/off control, but that does not mean it can automatically be replaced with a lighting dimmer. A dimmer must be rated for the load it is controlling and used according to the manufacturer's instructions.
Can I dim a floor lamp that plugs into the wall?
Yes. Use a purpose-built plug-in lamp dimmer that is rated for the lamp and bulb type.
Can a Repenic Smart Socket dim a lamp?
No. Repenic's Zigbee Smart Sockets provide smart on/off control, scheduling, automation and energy monitoring. They should not be used or described as lamp dimming outputs.
Will every LED bulb work with a dimmer?
No. The LED must be dimmable, and the lamp or driver must be compatible with the dimmer's control method and load range.
