Knightsbridge USB Sockets — Type A+A and Type A+C 2 Gang Sockets for UK Electricians

USB charging points have become a standard specification on new domestic and light commercial electrical installations. Customers fitting out kitchens, bedrooms, home offices, and hotel rooms routinely request sockets with built-in USB charging to eliminate plug adapters and free up the 13A outlets for appliances. Knightsbridge offers a broad range of 2 gang USB sockets covering white, chrome, and matt black finishes, and both Type A+A and Type A+C charging port combinations — giving electricians the flexibility to match any specification or interior. This guide covers four Knightsbridge USB socket options stocked at APM Electricals.

USB Type A vs Type C — What Electricians Need to Know

The two USB formats in current use for mains charging sockets are Type A (the rectangular port, used by older phones, tablets, and accessories) and Type C (the smaller oval port, now universal on Android phones, iPads, laptops, and most new devices). When specifying USB sockets, consider who will be using them:

• Dual A+A sockets are appropriate where multiple older devices need simultaneous charging — bedrooms with mixed device generations, student accommodation, and rental properties where the customer base is broad.
• A+C sockets are the forward-looking specification for kitchens, home offices, and new builds where USB-C is now the dominant standard. A+C sockets charge iPhones (from iPhone 15), Android handsets, tablets, and USB-C laptops without adapters.

All Knightsbridge USB sockets in this guide are SP (single pole) or DP (double pole) switched 13A 2 gang outlets with the USB charging ports integrated into the faceplate — there is no separate module to fit or wire, and no additional consumer unit space required. USB power is derived from the ring main via the socket's internal transformer.

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

Knightsbridge 13A 2G SP Switched Socket with Dual USB A+A

This is Knightsbridge's entry-level USB socket — a white curved-edge 2 gang SP switched outlet with two Type A USB charging ports sharing 2.4A at 5V DC. The curved-edge profile is the standard aesthetic for UK domestic wiring accessories; it fits existing back boxes without modification and matches the Knightsbridge curved-edge range of switches and standard sockets used throughout most domestic installations.

A practical upgrade over a standard 13A socket for bedrooms and hallways where customers want USB charging without extra adapters. The shared 2.4A output is sufficient for overnight charging of two smartphones simultaneously. Wiring is identical to a standard 13A socket — the USB transformer is internal. SP switching is appropriate for most domestic circuits.

• 2 gang 13A SP switched socket
• Dual USB Type A ports — 5V DC 2.4A shared
• Curved edge profile — white
• Fits standard 35mm single-gang back box
• Compatible with Knightsbridge curved-edge accessory range

13A 2 Gang DP Switched USB Socket with Type A+C — Curved Edge

13A 2 Gang DP Switched USB Socket with Type A+C — Curve

This is Knightsbridge's budget-entry curved-edge USB socket with a Type A and Type C charging combination — the most versatile port pairing available. The DP (double pole) switch disconnects both live and neutral on the 13A outlet, which is specified for kitchen sockets under BS 7671 where the circuit feeds the worktop area. This is the lowest-cost A+C option in the range and represents strong value for volume installations such as new-build developments or room-by-room upgrades.

Having one Type A and one Type C port means this socket charges any current device — USB-C phones and tablets on one port, USB-A accessories on the other — without requiring the customer to carry a multi-port adapter. For landlords and developers fitting out properties to a modern standard, this is the most future-proof USB socket at the sharpest price point.

• 2 gang 13A DP switched socket — BS 7671 compliant for kitchen worktop circuits
• Type A + Type C USB ports
• Curved edge profile — white
• Most versatile port combination for mixed-device households
• Lowest-cost A+C option in the Knightsbridge range

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

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

For kitchens, dining rooms, and living areas where the client has specified chrome accessories, this Knightsbridge socket delivers the A+C USB combination in a polished chrome faceplate with white insert. Polished chrome is the standard premium finish in UK domestic wiring accessories, matching chrome tap fittings, door furniture, and kitchen hardware. The white insert gives a clean contrast against the chrome border.

The dual A+C configuration (5V DC 4.0A shared) charges two USB-C devices simultaneously — useful in kitchens where phones are routinely charged at the worktop alongside a tablet or smart display. Chrome specification is economically straightforward when the rest of the kitchen accessories are in the same finish.

• 2 gang 13A SP switched socket
• Dual USB Type A + Type C — 5V DC 4.0A shared
• Polished chrome faceplate with white insert
• Matches Knightsbridge polished chrome switches and sockets
• Suitable for kitchen, dining room, and living area specifications

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

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

Matt black screwless sockets have become the premium specification for contemporary interiors — typically new-build apartments, high-end renovations, and designer kitchens where the architect or interior designer has specified black accessories throughout. The screwless faceplate removes visible fixing screws, giving a flat, unbroken surface that suits minimalist interior schemes. Knightsbridge's screwless range uses a clip-on faceplate mechanism over a standard mounting plate.

This socket carries dual USB A+A ports (5V DC 2.4A shared) and a black insert to match the matt black faceplate — there is no chrome or white contrast, delivering a fully coordinated black-on-black appearance. For electricians working on high-specification projects, having screwless matt black USB sockets available avoids delays on jobs where the designer has specified the finish before installation.

• 2 gang 13A SP switched socket
• Dual USB Type A — 5V DC 2.4A shared
• Screwless matt black faceplate with black insert
• Clip-on faceplate over standard mounting plate — no visible fixings
• Matches Knightsbridge screwless matt black switches and sockets range
• For contemporary and designer interior specifications

Specifying Knightsbridge USB Sockets

When specifying USB sockets on a new installation or upgrade, a few practical points apply:

• Back box depth: USB sockets carry an internal transformer and are slightly deeper than standard 13A sockets. A 35mm deep back box is recommended; 25mm boxes may be too shallow. Check the product datasheet if the existing back box is shallow.
• USB output shared vs per-port: All sockets in this guide share the USB output across both ports. A socket rated 2.4A shared delivers 1.2A per port when both are in use — sufficient for phone charging but slower for tablets. The 4.0A shared versions in the A+C options charge two devices at closer to full speed.
• DP vs SP switching: Double pole (DP) switching disconnects live and neutral and is required by BS 7671 for kitchen worktop circuits. SP switching (disconnects live only) is acceptable for general power circuits in other rooms. Specify DP in kitchens to ensure compliance.
• Finish matching: Knightsbridge USB sockets are designed to match the wider Knightsbridge switch and socket range. If the installation already uses curved-edge, flat-plate, or screwless Knightsbridge accessories, select the matching USB socket profile to maintain a consistent look across the board.
