Working from home is no longer a temporary arrangement for most people — it is a permanent part of how we work. Yet many home offices are still powered by a single double socket and lit by whatever ceiling fitting happened to be in the spare bedroom. A properly planned electrical setup makes a genuine difference to productivity, comfort, and reliability.
Here is what to consider when setting up — or upgrading — the electrical infrastructure in your home office.
Why a Dedicated Circuit Matters
Most bedrooms and spare rooms were designed with modest electrical demands in mind — a lamp, a phone charger, perhaps a television. A home office, on the other hand, might be running a computer, two monitors, a printer, a desk lamp, a phone charger, a router, and an external hard drive — all at once.
Running all of this from a shared circuit means you are competing with other rooms on the same ring main. If someone switches on a high-draw appliance elsewhere in the house — a vacuum cleaner, a heater — it can cause voltage dips or, in the worst case, trip the circuit and cut power to your equipment mid-task.
A dedicated radial circuit for your office, protected at the consumer unit, eliminates this risk. It ensures your office has a clean, stable power supply that is independent of the rest of the house. If you are considering this, it is worth checking whether your existing installation has capacity, or whether a consumer unit upgrade would be beneficial.
Socket Placement and Quantity
The golden rule for home office sockets is simple: you need more than you think. A minimum of four double sockets is a sensible starting point, and six is better if you have a multi-monitor setup or several peripherals.
Think carefully about placement:
- Desk level — sockets at or just above desk height keep cables short and accessible, and avoid the need to reach behind furniture
- Floor level — useful for equipment that sits under the desk, such as a desktop computer or UPS
- Opposite wall — a socket on the wall facing your desk is useful for a printer, a standing lamp, or charging devices away from your workspace
If you are fitting out the office from scratch, having sockets installed at desk height with integrated USB-A and USB-C charging points is a practical touch that reduces adapter clutter.
Lighting for Screen Work and Video Calls
Lighting is one of the most overlooked aspects of a home office, but it has a significant impact on comfort, eye strain, and how you appear on video calls.
Colour temperature
For office work, a neutral white light in the range of 4000K to 4500K is generally considered ideal. It is bright enough to feel alert and focused without the harsh, clinical feel of cool white (5000K+) or the drowsy warmth of a 2700K bulb. Look for LED fittings with good colour rendering (CRI 90 or above) for accurate colour representation.
Reducing glare
Glare on your screen is a common problem, particularly with ceiling downlights positioned directly above or behind you. The solution is to plan your lighting layout around your desk position. Downlights should be offset from the screen, and any light source behind you should be diffused or dimmable to avoid reflections.
Video call lighting
If you regularly take video calls, the lighting on your face matters. A light source in front of you and slightly above — such as a wall-mounted panel light or a positioned desk lamp — provides even, flattering illumination. Avoid having a window directly behind you, as this creates a silhouette effect on camera.
Task lighting
A good desk lamp supplements the overhead lighting for close work — reading documents, writing, or detailed screen work. An adjustable LED desk lamp with tuneable colour temperature gives you the most flexibility.
Ethernet vs WiFi
WiFi is convenient, but for a home office where reliable connectivity is essential, a wired ethernet connection is significantly better. It provides consistent speeds, lower latency (important for video calls and remote desktop connections), and is not affected by interference from neighbouring networks or household devices.
A single Cat6 or Cat6a ethernet run from your router to your office is straightforward to install and makes a noticeable difference to reliability. If your office is far from the router, or the WiFi signal is poor, this is often the single most impactful improvement you can make.
For homes where running a cable is impractical, a professionally installed mesh WiFi system with a dedicated access point near the office is the next best option.
Cable Management
A home office can quickly become a tangle of cables — power leads, monitor cables, USB connections, ethernet, and chargers. Good cable management is not just about aesthetics; it also reduces the risk of accidental disconnection and makes the space easier to clean and maintain.
Practical approaches include cable trays mounted under the desk, trunking along the skirting board, and floor boxes for under-desk connections. When sockets are installed at the right height and in the right positions, cable management becomes much simpler.
Surge Protection
Your home office equipment — particularly computers, monitors, and networking gear — is vulnerable to power surges. A surge can be caused by lightning, grid fluctuations, or even large appliances switching on and off elsewhere in the house.
At a minimum, use a quality plug-in surge protector strip for your desk equipment. For more comprehensive protection, a Type 2 surge protection device (SPD) installed at the consumer unit protects the entire property. This is particularly worthwhile if you have expensive equipment or work with data that would be difficult to replace.
UPS Considerations
An Uninterruptible Power Supply (UPS) provides battery backup during a power cut, giving you time to save your work and shut down gracefully. For most home offices, a small UPS rated at 600VA to 1000VA is sufficient to keep a computer and monitor running for ten to fifteen minutes — long enough to save and close everything safely.
A UPS also acts as a surge protector and line conditioner, smoothing out minor voltage fluctuations that can affect sensitive electronics over time. If you work with critical data or cannot afford unexpected shutdowns, a UPS is a worthwhile investment.
Planning Your Setup
The best time to plan your home office electrical layout is before the room is furnished. If you are converting a spare room, decorating, or building an extension, getting the electrical infrastructure right at that stage is far easier and less expensive than retrofitting later.
Consider what equipment you use now, what you might add in the future, and how your desk is positioned relative to windows and doors. A short consultation with an electrician can save considerable time and frustration — and the result is a workspace that supports you properly, day after day.
