**In short:** Yes, in most cases. A standing desk's control box draws a modest amount of power while moving and very little at rest, well within a standard UK 13 A extension lead. Use a good quality lead with a UK plug, keep the total load within its rating, do not daisy-chain leads, and do not share the lead with heaters or kettles. A surge protected strip is fine.

Standing desks need mains power for their motors, and the nearest wall socket is often already in use. That leads to a common question: is it safe to plug the desk into an extension lead or a power strip, or even a surge protector? This explainer covers what a desk draws, how UK extension leads are rated, what to avoid, and how to arrange power so everything moves with the desk. Always read your desk's manual, as makers may give specific instructions.

## How much power does a standing desk use?

The control box converts mains power for the motors. It draws noticeably more only while the desk is moving, which is usually for less than a minute at a time. At rest it draws a small standby current. The rating label on the control box gives the maximum input in watts or amps; check that figure rather than relying on a general rule.

Many desks also have a duty cycle, often about two minutes of running followed by a rest period, to protect the motors. That means the desk cannot run long enough to load a lead heavily for long.

## UK extension lead ratings

Most UK extension leads and power strips are rated at 13 A, which is about 3,000 W at 230 V. Some are rated lower, such as 10 A, especially on cable reels or thin leads. The rating is printed on the lead or plug. The total of everything plugged into the lead must stay below that figure.

A standing desk, monitors, a laptop and phone chargers together are usually well within 13 A. Problems start when high-power appliances share the lead.

| Device | Typical use | OK on desk lead? |
| --- | --- | --- |
| Standing desk control box | Short bursts when moving | Yes |
| Monitors, laptop, chargers | Low steady draw | Yes |
| Desktop PC | Moderate | Usually, check total |
| Fan heater, oil heater | High, continuous | No, use a wall socket |
| Kettle, toaster | Very high | No |

What to share a lead with

## What not to do

Electrical Safety First, the UK charity, advises against daisy-chaining extension leads and against overloading sockets. The same applies to desks.

- Do not plug one extension lead into another
- Do not use a cube adapter in an extension lead
- Do not run the lead under a rug or where it can be crushed by the desk
- Do not leave a cable reel coiled while in use
- Do not use a lead with damaged cable or a cracked plug

Note: If a lead feels warm, smells of burning or shows scorch marks, unplug it and stop using it. Ask a qualified electrician if you need extra sockets fitted.

## Surge protectors and smart plugs

A surge protected power strip works the same way as a normal one and is fine for a standing desk. It may help protect your monitors and computer from spikes. It does not change the load rating.

Smart plugs and timer plugs are best avoided for the desk itself. Cutting power while the desk is moving can trigger an error that needs a reset, covered in our [reset guide](https://chairandposture.co.uk/blog/how-to-reset-a-standing-desk). Power cuts can do the same.

## Mounting the lead on the desk

The neatest setup is a power strip fixed under the desktop, so the desk's own control box, monitors and chargers all plug in there and move with the desk. Only one lead then runs from the desk to the wall, with enough slack to reach the highest position. Our [cable management guide](https://chairandposture.co.uk/blog/standing-desk-cable-management) covers this step by step.

Check the lead from the desk to the wall is long enough at full height and does not cross a walkway.

## Desks with built-in sockets

Some desks include USB ports or sockets in the handset or a power module. These are convenient for phones, but check their rating before plugging in anything larger. Our [electric standing desks guide](https://chairandposture.co.uk/best/best-electric-standing-desks) notes USB and charging features where listings mention them.

## Frequently asked questions

**Can you plug a standing desk into a power strip?** Yes, in most cases, if the strip is a good quality UK lead and the total load stays within its rating.

**Can you plug a standing desk into a surge protector?** Yes. A surge protected strip is fine and may also protect your other equipment.

**Do standing desks use a lot of electricity?** No. They draw power mainly while moving, for short periods, and very little at rest.

**Can I use an extension cord reel?** Only fully unwound, and check its rating. A fixed power strip is a better long-term choice.
