For a UK office, compare the exact UK model, cable reach, protection information and indicator instructions before buying. Belkin BSV603af2M and Brennenstuhl Premium-Line 1951163400 are two documented options, with different cable lengths and differently expressed surge ratings.
This is a research-based comparison reviewed on 21 September 2026. We have not tested surge suppression, durability or fault behaviour. Links go to non-affiliate manufacturer pages; check current retailers, price and availability there. The header is a category illustration, not a photograph of a tested unit.
For mounting and charging features rather than surge specifications, see our desk power-strip guide.
Two UK options to compare #
| Model | Sockets and cable | Published protection information | Practical decision |
|---|---|---|---|
| Belkin BSV603af2M | Six sockets; 2 m lead | 650-joule rating | Compare if 2 m reaches your intended position |
| Brennenstuhl Premium-Line 1951163400, GB version | Six sockets; 3 m lead | 60,000 A surge-current specification; protection indicator | Compare if you need the longer route and documented fastening options |
These ratings describe different quantities. The larger printed number is not evidence that one product provides proportionally better protection. We have not assigned a winner from a laboratory test or invented a minimum joule requirement for your computer.
Belkin BSV603af2M: a six-socket, 2 m option #
Belkin’s UK page specifies six protected sockets, a recessed power switch and a 650-joule rating. It also describes a “Not-Grounded” indicator; consult the instructions for what the indicators mean and what action to take.
The manufacturer’s page says its protective components wear out and gives replacement guidance. Read that guidance before buying, then retain the instructions and purchase record. An indicator concerning earthing should not be treated as interchangeable with a light indicating the condition of surge protection.
Choose it for comparison when: its cable reaches the socket and the plug arrangement fits your equipment. Check first: the exact UK suffix and the instructions. Connected-equipment warranty wording has conditions; do not treat it as an unconditional guarantee that equipment cannot be damaged.

Brennenstuhl 1951163400: longer lead and fastening options #
The UK manufacturer page lists the Premium-Line 1951163400 GB version with six sockets, a 3 m cable, a BS 1363 plug and nominal current of 13 A. It documents screw or cable-tie fastening and a light indicating that surge protection is active. The model is for indoor use.
Its 60,000 A figure is a surge-current specification, not the current you can continuously draw from its sockets. Use the marked operating limits on the actual product and its instructions when checking the load.
Choose it for comparison when: the 3 m route and documented fastening arrangement suit your workspace. Check first: you have selected article 1951163400. Similar Premium-Line names cover other socket counts and USB configurations; their features are not interchangeable.

What a buying checklist should establish #
- UK configuration: identify the model and plug arrangement, rather than choosing a US version with a similar name.
- Enough usable sockets: allow for bulky power adaptors, not merely the number of devices on a list.
- A suitable route: measure the distance to the wall socket and any movement of a sit–stand desk.
- Clear instructions: find the operating limits, indicator meanings and replacement procedure before concealing the unit in a tray.
- The actual need: voltage-surge protection and battery backup are different jobs. Neither socket count nor a protection rating tells you how long equipment can run during an outage.
If the mains installation needs assessment or you are unsure about a fault, consult a registered electrician rather than treating an extension lead as a repair for the wiring.
Load and condition still matter #
Electrical Safety First’s extension-lead guidance says not to exceed the marked current rating or plug one extension lead into another. Surge protection does not create extra load capacity. Check connected equipment together rather than assigning the full rating to each socket.
Keep the unit accessible for inspection. Damage, scorching or burning smells need attention; hiding the strip does not address them. Follow the exact model’s replacement guidance rather than applying a universal lifespan to every surge protector.
For the physical layout, our under-desk cable guide explains supports, cable slack and access. Keep manufacturer-required ventilation clear and avoid putting the installation where chair movement can pull on leads.
Frequently asked questions #
Is a surge protector the same as an extension lead? #
An extension lead adds reach or sockets. A surge-protected version also has a documented surge-protection function. Do not infer that feature from socket count, a power switch or USB charging ports.
How many joules do I need for an office? #
This guide does not set a universal minimum. Compare documented specifications for the exact model and follow its intended-use guidance. A joule figure cannot be directly ranked against another product’s surge-current figure in amperes.
When should I replace a surge protector? #
Follow the exact model’s replacement guidance and the instructions for its protection indicator. Stop using damaged equipment. Do not assume that a working power switch proves the surge-protection components are still effective.
Will a surge-protected extension lead keep my PC on during a power cut? #
No. The two extension leads compared here do not provide battery backup. If continuity through an outage is essential, assess a suitably specified UPS separately.
