Knightsbridge USB Sockets — 1G and 2G Switched Sockets with USB Charging for UK Electricians

USB charging sockets have become one of the most-requested upgrades in domestic first-fix and retrofit electrical work. Clients want to charge phones, tablets and laptops without hunting for a plug-in adaptor, and installing a combined 13A socket with built-in USB ports is now a standard item on any kitchen, bedroom or study specification. Knightsbridge USB sockets cover the full range — from a basic white 1G with a single USB-A port through to screwless matt black 2G sockets with USB A+C fast-charging.

At APM Electricals we stock 14 active Knightsbridge USB socket variants. Below are four representative options covering entry-level white, mid-range value, polished chrome and premium screwless matt black.

Knightsbridge 13A 1G Switched Socket with USB-A — White

Price: £13.99 inc VAT

The Knightsbridge 13A 1G square-plate switched socket with USB-A is the workhorse entry-level option for bedroom and hallway retrofits. The single USB-A port outputs 5V DC 2.1A — enough for overnight phone charging or a bedside lamp with smart-home adaptor. The white moulded finish matches standard square-plate grid faceplate systems and fits a standard 25mm back box. Single pole switched for safety. Ideal for budget-conscious domestic installs where clients want the USB convenience without the premium finish uplift.

• 13A DP switched 13A socket
• Single USB-A port (5V DC 2.1A)
• White moulded square-plate finish
• Standard 25mm back box fit
• Single pole switched

Knightsbridge 13A 2G SP Switched Socket with Dual USB A+A — Curved Edge White

Price: £18.99 inc VAT

Step up to the 2-gang curved-edge version and you get two 13A switched sockets plus two USB-A charging ports in a single faceplate — the most practical layout for a bedside table or kitchen worktop where the client needs to run a kettle and charge two devices at once. The curved edge profile gives a softer look than a flat square plate, popular in new-build bedrooms and living rooms. Single pole switched, 5V output from both USB ports, white insert. A solid mid-range choice that competes directly with Screwfix's own-brand USB sockets at roughly the same price point but with the Knightsbridge quality and compliance credentials.

• 2 x 13A SP switched sockets
• Dual USB-A ports (5V DC)
• Curved edge white moulded faceplate
• Standard 35mm back box recommended
• Single pole switched

Knightsbridge 13A 2G SP Switched Socket with Dual USB A+C — Polished Chrome

Price: £19.43 inc VAT

Polished chrome is the go-to finish for high-spec kitchens, bathrooms (above zone 2), and commercial hospitality projects. This 2-gang variant pairs the 13A double socket with a USB-A port and a USB-C port — the A+C combination is increasingly the specification request as USB-C becomes standard on phones, tablets and laptops. The USB-C port charges at 5V DC 4.0A, noticeably faster than a standard 2.4A USB-A charger, which matters to clients who are fast-charging a 12-inch iPad or a MacBook Air. Polished chrome finish, white insert. Priced at £19.43 this is exceptional value for a chrome USB socket — Screwfix lists comparable chrome USB sockets at £22–£28.

• 2 x 13A SP switched sockets
• 1 x USB-A + 1 x USB-C ports (5V DC 4.0A total)
• Polished chrome faceplate, white insert
• Standard 35mm back box
• Single pole switched

Knightsbridge 13A 2G Screwless Socket with Dual USB A+A — Matt Black

Price: £32.99 inc VAT

The screwless matt black finish is the designer electrician's specification for boutique hotel rooms, high-end residential open-plan spaces and restaurant fit-outs. No visible screws on the faceplate means a clean flush look, and the matt black colour pairs naturally with dark kitchen units, gunmetal appliances and monochrome interior schemes. The 2G layout gives two 13A sockets plus dual USB-A charging (5V DC 2.4A per port). Fits the same 35mm back box as the white range but delivers a premium aesthetic at a price that still undercuts B&Q's equivalent screwless USB ranges. Where you've already specified Knightsbridge matt black switches and sockets in a room (see our matt black screwless range blog), this USB socket completes the set.

• 2 x 13A SP switched sockets
• Dual USB-A ports (5V DC 2.4A per port)
• Screwless matt black faceplate
• Standard 35mm back box
• Single pole switched

Which Knightsbridge USB Socket Should You Specify?

For a fast rule of thumb: match the USB socket finish to the rest of the sockets in the room, then decide on A-only vs A+C based on client expectation. Most domestic clients are happy with dual USB-A unless they specifically ask about fast-charging or mention USB-C devices. For commercial hospitality — hotels, serviced offices, short-let apartments — A+C is the correct specification because guests will arrive with USB-C laptops and USB-A phone cables and expect to charge both simultaneously.
