Knightsbridge Flat Plate & Screwless 13A Sockets — Polished Chrome and Brushed Chrome for UK Electricians

When a client specifies premium finishes for their sockets, the standard white moulded plastic isn't going to cut it. Knightsbridge's Flat Plate and Screwless ranges give electricians a professional solution: slim metal faceplates in polished chrome and brushed chrome, designed to sit flush against the wall without exposed screw heads. The result is a cleaner look that architects, interior designers, and high-end residential clients increasingly expect — and that installers can fit in the same back box as a standard socket.

At APM Electricals we stock both the Flat Plate (with concealed screws behind the rocker) and Screwless (tool-free front plate removal) variants across single and double 13A sockets. Here are four of the most popular options.

1. Knightsbridge 13A 1G DP Switched Socket — Flat Plate, Polished Chrome with White Insert

Price: £9.99 inc VAT

The single-gang flat plate socket in polished chrome is the go-to choice where a single 13A outlet is all that's needed but the finish has to match the room. The polished chrome faceplate has a mirror-bright finish suited to contemporary and traditional schemes alike — kitchens, utility rooms, home offices, and reception areas. The white insert provides contrast between the faceplate and the rocker, making the socket easy to identify. Double-pole switching isolates the load at both live and neutral for full protection. Fits standard 25mm or 35mm single-gang back boxes.

When to specify: Single-outlet positions in high-specification rooms, desk-level sockets in executive offices, or anywhere the client has specified chrome metalwork throughout.

2. Knightsbridge 13A 2G DP Switched Socket with Twin Earths — Flat Plate, Polished Chrome with White Insert

Price: £13.70 inc VAT

The double-gang version of the polished chrome flat plate is the most commonly specified socket in premium residential work. Twin earths mean you can safely extend a spur or feed a local sub-circuit without sharing an earth connection. The flat plate profile — screws are present but recessed and finished to blend with the faceplate — gives a neater result than standard sockets while still allowing removal with a standard flat-head screwdriver for maintenance access. Polished chrome suits rooms with chrome mixer taps, door furniture, or curtain poles.

When to specify: Living rooms, master bedrooms, and kitchens where the client has a chrome finish theme; new-build premium fit-outs; rewires where all socketry is being upgraded to match new light switches.

3. Knightsbridge 13A 2G DP Switched Socket with Twin Earths — Screwless, Brushed Chrome with Black Insert

Price: £14.99 inc VAT

The screwless double socket in brushed chrome with a black insert is a favourite in contemporary and industrial-style interiors. The screwless front plate clips magnetically onto the chassis — no exposed fixings, no screw holes to fill if the plate is ever removed, and a completely clean face. The brushed chrome finish is a satin stainless look that resists fingerprints better than polished chrome, making it practical as well as attractive. The black insert (rocker and socket surround) creates a strong contrast against the brushed metal faceplate.

When to specify: Modern kitchens and open-plan living spaces, dark-finish interiors, hospitality and commercial refurbishments, media rooms where AV and gaming loads demand multiple outlets.

4. Knightsbridge 13A 2G DP Switched Socket with Twin Earths — Screwless, Polished Chrome with White Insert

Price: £14.99 inc VAT

The screwless double socket in polished chrome with white insert combines the highest-specification finish with the cleanest possible front elevation. There are no screws at all visible on the faceplate — the front clips on and off by hand, giving an unbroken mirror-chrome surface. This is the socket specified at the top end of the residential market: bespoke new builds, listed building fit-outs, and prestige refurbishments where every detail has to be right. White insert keeps the socket functional and easy to use while the chrome surround dominates the aesthetic. Fits standard 35mm double back boxes.

When to specify: Premier residential projects, show homes, hotel room fit-outs, and any installation where the client's brief specifies "no visible screw heads" throughout.

Flat Plate vs Screwless — What's the Difference?

Both ranges use the same back box (standard 25mm single or 35mm double) and share the same electrical specification. The difference is cosmetic and installation-specific:

• Flat Plate: The faceplate is held by screws that are visible but recessed and colour-matched to the faceplate. Removal requires a screwdriver. Better suited to locations where the socket may be moved or extended in future, and where a slightly more traditional trim is acceptable.
• Screwless: The front plate is a separate clip-on cover with no visible fixings. The chassis is screwed to the back box in the normal way; the front cover then clips over. Removal is by hand (a flat-head tool helps on some variants). Preferred for show-quality finishes where zero visible hardware is the brief.

From a wiring perspective, both are identical — the same terminals, the same twin-earth facility, the same double-pole switching. Specify based on the finish requirement and the client's maintenance expectations.

Available Finishes at APM Electricals

The Knightsbridge Flat Plate and Screwless ranges are available in multiple finishes to match any project specification:

• Polished Chrome (PC): Mirror-bright finish. Available with white or black inserts.
• Brushed Chrome / Satin Chrome (BC): Matte metallic finish. Available with white, grey, or black inserts.
• Matt Black (MB): Full black faceplate with black insert. Popular in industrial and media-room installations.
• Matt White (MW): Premium white screwless finish — a step up from standard white moulded for customers who want the screwless aesthetic without chrome.

Singles (1G), doubles (2G), and USB-combination variants are stocked across the main finishes. The range extends to 10AX switches, dimmer switches, and cooker switches in matching flat plate and screwless formats — so you can complete an entire first fix and second fix in one consistent finish.
