The best Kopp sockets, compared.
Top pick: Kopp Paris flush sockets, 6-pack – Highest score in the set: about £18.31, 4.8 from 802 ratings, IP20, with screwless terminals described in the reviews. Soft fixing screws are the known weak point. Best value: Kopp Nautic horizontal double, white – About £2.85, 4.4 from 473 ratings, IP44 and a hinged lid. The cheapest clear IP44 double here with at least 100 ratings. One canopy review reports heat after about two years. Updated October 2026.
Kopp sockets of this type are continental protective-contact wall outlets, commonly Type C, E or F, rated 16 A at 250 V. A standard UK three-pin plug needs an adaptor before it will seat. Households use them in a workshop, garage, outbuilding, caravan or a property already wired to continental practice. A living-room Type G replacement stays a BS 1363 outlet. Match the socket to the installation you already have. Flush inserts need a compatible back box and often a cover frame ordered separately. Surface boxes fix to the wall, and some accept only rigid conductors with no strain relief. IP20 is for dry rooms. IP44 is splash protection for a utility, covered patio or workshop. Count the gangs, and check whether a double includes an internal bridge or needs link wires. Terminals should be plug-in, screwless or screw. Sixteen amps is a nominal current. New circuits follow BS 7671 and belong with a registered electrician. Mounting, IP rating and terminals are set out in the [socket buying guide](/hub/sockets-and-extension-leads/kopp-sockets/sub/kopp-sockets-buying-guide).

Question 1 of 2
Where will the socket sit?
The Kopp Paris six-pack, model 920702011, is six flush protective-contact sockets at £18.31, which works out at about £3.05 an insert before any cover frame. The amazon.co.uk line is 4.8 from 802 ratings, the highest stars in this set, and the listing prints IP20, 16 A, 250 V, a high-gloss face and increased touch protection. Each face is given as about 5.7 by 5.7 cm. Reviewers, from Germany and other European countries rather than the United Kingdom, praise screwless terminals that hold and release, plugs that sit firmly, and a neat Paris finish. The repeated fault is soft fixing screws whose cross heads strip when they are tightened. The file does not say whether a cover frame is in the pack, and the weight of 9.07 g for six inserts is not a usable mass. Bullets name a living room, bathroom, kitchen and cellar, but IP20 is not a splash rating, so a bathroom zone that needs a higher IP is outside this pack. It is the top pick when you are fitting several dry-room Paris inserts and you will budget the frames separately.
Pros
Cons
Best for: A dry-room refurb that needs several arctic Paris inserts and a separate frame order.
Less suitable: A single gang, a garage splash point, or a UK three-pin back box.
Specifications
Common questions
Is a cover frame included in the six-pack?
The listing does not say whether a cover frame is in the pack. Bullets mention Paris design colours elsewhere.
What protection rating is stated?
The IP field is IP20. Outdoor use is a question only with no answer in the raw file.
How do reviewers describe the terminals?
Reviews in the file describe screwless terminals that hold the conductor and can be released again.
The Kopp Paris 923502087 is one flush protective-contact insert, arctic white, 16 A at 250 V and IP20, listed at £4.08 with 4.7 from 95 ratings. The bullet says the cover frame for one to four compartments must be ordered separately, and the contents line is the earthing-contact socket without that frame. Compatible devices are named as plug types C, E or F. The face is high-gloss plastic, about 5.7 by 5.7 cm and 70 g, with Germany as the stated origin and CE on the specification. Written reviews are short and from Germany, and many of the 25 blocks have no body text. One review says a thread was defective, so the frame could not be fixed until it was recut. Another describes a six-piece order arriving loose in a paper bag with scratched gloss, which does not match this one-gang listing, so do not treat that packing story as this ASIN. It is the single insert when you need one Paris gang and you already have the frame, and a weak pick if you wanted a large review sample or a hinged lid.
Pros
Cons
Best for: One dry-room Paris gang when the matching cover frame is already on the wall or on a separate order.
Less suitable: A six-gang refurb, a splash location, or a buyer who needs a large written review sample.
Specifications
Common questions
Is the cover frame included?
The bullet says the cover frame for one to four compartments must be ordered separately.
Which plug types does the listing mention?
The compatible devices field names electrical appliances with plug type C, E or F.
Does the listing include a hinged lid?
A cover question is unanswered. The deliverable is the earthing contact socket without a frame in the contents line.
The grey Kopp Nautic 136956008 is a vertical surface double, 16 A at 250 V AC, listed at £8.30 with 4.6 from 1,480 ratings. The box is about 16 by 8.3 cm, IP44, with a hinged lid and increased touch protection, and the bullet describes a removable interior with plug-in terminals up to 2.5 mm². Reviewers, mostly from mainland Europe rather than the United Kingdom, praise solid plastic, a lid that closes, and room once the insert is out. The repeated complaint is that there is no factory link between the two outlets, so you add link wires yourself. One review says a locating pin broke the first time the insert came out. The listed weight of 9.07 g is not a credible mass for a box this size, so treat that figure as a catalogue error. Outdoor use is only a question on the page. The printed locations are cellars, washrooms, garages and workshops, which is splash protection rather than a jet-proof outdoor socket.
Pros
Cons
Best for: A narrow vertical splash point in a cellar, washroom, garage or workshop that already uses continental outlets.
Less suitable: A wide horizontal bench, unsheltered rain, or anyone who expected the two gangs to be linked at the factory.
Specifications
Common questions
Is there a factory link between the two outlets?
Reviews say there is no internal bridge between the two outlets, so the fitter may need to add link wires.
What does IP44 mean on this Nautic box?
The listing prints IP44 and splash protection against solid objects larger than 1 mm. Outdoor use is a question only on the page.
How are conductors connected?
The bullet describes a removable interior, plug-in terminal, and conductors up to 2.5 mm² with large wiring space.
The Kopp Nautic 138556008 puts a toggle switch and one socket in a vertical grey surface box, 16 A at 250 V, listed at £4.77 with 4.5 from 3,391 ratings. It is IP44 with a hinged lid, and the bullet says the interior comes out onto plug-in terminals for cable up to 2.5 mm². Reviewers describe a clear switch click and a socket that holds a plug, and they call the grey plastic fair for a cellar or workshop. Some also call the plastic hard, and the lid spring and shutter less than premium. One text in the sample is about a different two-rocker series switch, so those 50 texts are not a clean single-product set, and they are overwhelmingly from Germany. The weight line again prints 9.07 g, which you should ignore. CE is stated on the listing. It is the combination to choose when you want one switched outlet under a lid, and a poor match if you needed two sockets or unsheltered rain.
Pros
Cons
Best for: A cellar, garage or washroom point where one continental socket needs a local toggle under an IP44 lid.
Less suitable: A two-gang bench, a décor flush plate, or an unsheltered outdoor wall.
Specifications
Common questions
Does this unit combine a switch and a socket?
Yes. The title and bullets describe a toggle switch combined with one socket in a vertical surface box.
Is it suitable for unsheltered outdoor rain?
Outdoor use is a question only. The listing names wet rooms and IP44 splash protection, not a higher jet rating.
How is the interior wired?
The bullet says the interior is removable, uses a plug-in terminal, and accepts cable up to 2.5 mm².
The Kopp Nautic listing B07BKGM3Y7 is £5.67 with 4.5 from 1,750 ratings, model 137015003, and the page does not agree what you are buying. The title says an economy pack and black, the colour field says charcoal, and the item type says an anthracite horizontal double earth-contact socket with a hinged lid at IP44. A bullet instead names a surface-mounted switch at 10 A or 10 AX, while the amperage field says 16 A. Reviewers in the file discuss a double socket, which matches the item type more than the switch bullet, and those texts are mostly from Germany and the Netherlands. They want the dark finish and call the plastic acceptable, but they also report no factory link between the outlets, a soft wall base where screws pull through, and terminals that one Dutch review calls poor. Included components say one socket, so the economy-pack title is not a counted multi-pack in this file. Buy it only if the photo and the item type match the double you need, and leave it if a clean switch specification is what you came for.
Pros
Cons
Best for: A sheltered horizontal splash point where you have checked the photo is the anthracite double, not a switch.
Less suitable: Anyone who needs a single, unambiguous specification before they order.
Specifications
Common questions
Is this listing a switch or a double socket?
The file flags a conflict: one bullet names a surface-mounted switch at 10 A while the item type describes a two-gang earth-contact socket at IP44.
Do I need link wires between the outlets?
Reviews say there is no factory link between the two outlets, so the fitter adds a bridge.
What finish colours are named?
The title says black, the colour field says charcoal, and the item type says anthracite.
The arctic white Kopp Nautic 137002003 is a horizontal surface double, 16 A at 250 V AC and IP44, listed at £2.85 with 4.4 from 473 ratings. That is the lowest shelf price in this set for a hinged-lid double, and the listing states CE with no manufacturer guarantee. Reviewers, almost all from Germany, say there is room around the terminals and that the box can be wired singly or looped, though several struggle to seat the conductors and one gave up and refitted an old screw-terminal socket. Fixing holes sit in deep pockets, which makes the screws hard to reach, and one review says a switch insert sits too deep to swap in. A separate review says that after about two years under a canopy the RCD tripped, the inners had deteriorated, there was sparking, and cable insulation had burnt. That is one account, not a failure rate. A bullet says surface-waterproof, which is stronger wording than the IP44 field. At 218 g and about 15.3 by 7.5 cm it is the best value splash double here if the terminals suit you, and the wrong buy if you need a stated warranty or open-rain protection.
Pros
Cons
Best for: A sheltered horizontal splash point where you want the cheapest IP44 double in this set and can wire the terminals.
Less suitable: Unsheltered rain, a job that needs a printed warranty, or a swap to a switch insert.
Specifications
Common questions
What IP rating is printed?
The listing prints IP44. A bullet also says surface-waterproof, which is not the same as a formal IP test claim in every context.
Are the fixing screws easy to reach?
Reviews describe fixing holes in deep pockets and hard-to-reach screws during installation.
Can the insert be swapped for a switch module?
One review says a switch insert sits too deep, so the socket insert cannot be swapped for a switch.
The Kopp 102502002 is a surface-mounted double earth-contact outlet, 16 A at 250 V, listed at £5.26 with 4.1 from 5,448 amazon.co.uk ratings. The face is arctic white thermoplastic, about 10.1 by 6.4 cm and 93 g, and the listing says it is only for fixed wall mounting with rigid conductors and without strain relief. Reviewers in the file, mostly from Germany rather than the United Kingdom, split between a tidy box that holds plugs and screw terminals that are fiddly and hard to reach. One reviewer says the cable-securing bridge sits at the wrong end compared with the diagram. No IP rating is printed, and one review says it cannot be watertight because it is an indoor fitting. A bullet also says 2-pin while the title says earth contact, so treat the earth-contact line as the product type. At this price it is a plain indoor surface double with the largest rating count here, and it is the wrong box if you need a hinged lid or flexible cord.
Pros
Cons
Best for: An indoor surface run that already uses continental earth-contact outlets and rigid cable.
Less suitable: Flexible cord, a splash-prone garage, or a replacement for a UK three-pin socket.
Specifications
Common questions
Does this Kopp double have screw or clamp terminals?
Reviews in the listing describe screw terminals, not clamps, and say the contacts can be hard to reach during fitting.
Can I use flexible cable with this surface socket?
The bullet says it is only suitable for fixed wall mounting and rigid conductors, without strain relief.
Is this socket weatherproof?
Weatherproof is a question only on the listing. One reviewer says it cannot be watertight because it is an indoor fitting.
Seven amazon.co.uk listings were scored for this page. Weights sum to 100. Shelf prices, stars and review counts are the figures stored on 20 October 2026. No lab test was run. Star points are 50 plus 20 for each star above 3.5. Review points are the minimum of 12 and the log of the count. Feature points cover a matching IP rating, a hinged lid, described terminals, CE, a double or a switch, and named plug types C, E and F. Points come off when the title disagrees with the item, when a severe heat report is in the file, when the listed weight is implausible, when no IP rating is printed, when a review describes a different product, and when a fitting fault repeats. Written reviews in these files are mostly from outside the UK, so the star line is a volume signal.
Amazon stars
46%Star points are 50 plus 20 for each star above 3.5. That is 76 at 4.8 stars and 62 at 4.1. The figure is the amazon.co.uk line for that ASIN. Most written reviews in the files are from Germany and other European countries.
Review volume
14%Review points are the minimum of 12 and log10 of the count, times 4, rounded. That is 12 at 802 ratings and above, 11 at 473, and 8 at 95. A large count does not turn a non-UK sample into UK fitter consensus.
IP rating
12%Six points when an IP rating is printed and matches the series: IP44 on Nautic, IP20 on Paris. Three points come off when no IP rating is printed. IP44 is splash protection, not a jet-proof outdoor rating.
Lid, terminals and CE
14%Three points for a hinged lid, three when terminals are described as plug-in, screw or screwless, and two when CE is stated on the listing.
Gangs, switch and plug types
8%Two points when the unit is a double or includes a switch, and two when the listing names plug types C, E and F.
Listing consistency
6%Eight points come off when the title, the current and the item type disagree. Four come off for one severe heat or trip report, three for an implausible listed weight, three when the review file contains a different product, and two for a repeated fitting fault.
The checks run in this order: continental or BS 1363, flush or surface, the IP rating, then gangs, bridges and terminals. The table is the seven stored listings from 20 October 2026. None of these sockets was tested in a lab for this page.
A protective-contact socket in this comparison is a continental wall outlet, commonly in the Type C, E or F family, rated 16 A at 250 V. UK homes normally use shuttered BS 1363 thirteen-amp sockets. A standard UK plug needs an adaptor before it will seat in one of these outlets. Regulation 35 of the Electrical Equipment (Safety) Regulations 2016 requires plug-in devices sold for UK domestic use to suit BS 1363 sockets. Fixed wiring follows BS 7671, the IET Wiring Regulations.
These outlets do not accept a standard UK three-pin plug without an adaptor. A cracked BS 1363 socket needs a BS 1363 replacement, or a redesigned circuit and back box. Regulation 35 of the 2016 safety regulations covers plug-in devices sold for UK domestic use.
IP44 is splash protection under IEC 60529. It suits some damp locations when the enclosure and RCD protection are right. It is not a jet-proof rating for unsheltered rain. A surface-waterproof bullet is stronger wording than the IP44 field.
Some doubles ship without an internal link, so the fitter adds link wires. Some surface listings allow only rigid conductors and fixed wall mounting, with no strain relief. Flexible cord is the wrong cable for that wording.
Confirm the installation uses continental sockets before you order. If the wall is a normal UK three-pin outlet, the replacement is a BS 1363 product. Regulation 35 of the Electrical Equipment (Safety) Regulations 2016 requires plug-in devices sold for UK domestic use to suit BS 1363 sockets. Fixed wiring follows BS 7671. The Plugs and Sockets etc. (Safety) Regulations 1994 set out the thirteen-amp system and show why a UK plug does not seat here. IP rating is the next stable check.
Flush inserts and surface boxes are different jobs. A Paris insert needs a compatible back box, and the cover frame is often a separate order. Nautic and the standard programme are surface boxes that fix to the wall. Some of those lines accept only rigid conductors and give you no strain relief. Flexible cord is the wrong cable for that wording. Surface boxes as a wider category sit in the [surface-mounted socket comparison](/hub/sockets-and-extension-leads/surface-mounted-socket).
Three typical situations, each with a recommendation from this comparison.
You want a lidded surface double where splash matters more than a decor plate. The grey vertical Nautic is about £8.30, with 4.6 from 1,480 ratings, IP44 and plug-in terminals up to 2.5 mm². There is no factory link between the gangs, and the listed weight of 9.07 g is not a usable mass.
You are matching continental faceplates in dry rooms. The Paris six-pack is the top pick at about £18.31, with 4.8 from 802 ratings. Budget the cover frames separately. Fixing screws are described as soft, and IP20 is not a splash rating.
These outlets are the wrong part for a cracked UK three-pin socket. The standard-programme double is an indoor surface earth-contact box at about £5.26, with 4.1 from 5,448 ratings, and it is only for rigid conductors. Use it when the circuit is already continental.
The top pick is the Kopp Paris flush six-pack, model 920702011, at about £18.31, with 4.8 from 802 ratings. It is the highest score in the set: IP20, screwless terminals in the reviews, and CE stated. Fixing screws are described as soft, cover frames are not confirmed in the pack, and the listed weight of 9.07 g is not a usable mass. The best value is the arctic white horizontal Nautic double, model 137002003, at about £2.85, with 4.4 from 473 ratings. It is the cheapest IP44 hinged double here with a clear identity and at least 100 ratings. The anthracite listing ties that score and costs more, and its title does not agree with the item type, so it does not take the value award. One canopy review on the white double reports heat and a trip after about two years.
