PlugSafe  Protecting BS 1363 - the world’s safest mains plug and socket



PlugSafe is a volunteer organisation  working with other bodies to fight the threats to UK plug safety due to abuses, illegal counterfeits and a loophole in the standard itself.

Counterfeit Plugs

The Plugs and Sockets, etc. (Safety) Regulations 1994 were introduced to provide a regulatory regime to address issues regarding consumer safety. There were concerns that consumer safety was compromised by the substantial quantity of counterfeit and unsafe electrical plugs and sockets being placed on the UK market.  Despite this, there are a number of web retailers who advertise counterfeit plugs which, although being fraudulently marked “BS 1363”, are not compliant. These plugs are usually offered as part of a complete lead with a socket on the other end.

NOTE: CE Marking is NEVER appropriate for domestic mains plugs and sockets.  The CE Marking scheme is a self-certification scheme to indicate that a product complies with the relevant EU Directive.  There is no such thing as “CE approval”.  Domestic plugs and sockets, such as those conforming to BS 1363, are controlled by national standards, not EU standards, and must not therefore have a CE Marking applied to them.  (See page 7 of Guidlines on the application of Directive  2006/95/EC )

We are always looking for user experiences with counterfeit UK plugs and cables.  We are especially interested in first hand experience of sparking, melting and burning (often reported in Amazon customer reviews of counterfeits).  Please tell us about your experience.

A common indicator of a counterfeit plug is an earth pin which is partially insulated. BS 1363 requires that all power pins (the shorter pins) are partially insulated. However, earth pins must be solid brass, or, in the case of plugs intended solely for use with non-earthed devices, solid plastic. BS 1363 is quite specific, clause 12.16 states "Sleeves shall not be fitted to any earthing plug pin."  Having a sleeve on an earth pin is dangerous because it can prevent there being any contact to the earth of the socket.  To ensure that the earth connection is made as soon as the plug touches the socket many sockets place the contact right at the faceplate, this means that continuity is lost as soon as a plug with a sleeved earth is fully inserted!

PLEASE NOTE: Plugs with partially sleeved earth pins are ALWAYS counterfeit, and are not allowed to be sold, even for non-earthed applications.


The power lead shown above is the worst type we have seen.  We bought them from suppliers “Star e-shop” and “eBlink”, and have also seen them offered by other and suppliers.  These leads have the following faults:
•Counterfeit fuse ( a very crude imitation with no approval marks, no sand filling, loose end caps) - it was not even connected to anything!
•Partially sleeved earth pin, and all pins are the wrong size.
•The colour coding of the wires is not in conformance with any known standard, and the C5 connector is wired in reverse!
•The moulding of the plug/cable assembly has taken place with the fuse carrier and fuse in place, with nothing to prevent the moulding material flowing into the fuse chamber, one of the samples was almost entirely filled in this way completely sealing in one end of the fuse.
•The plug is marked: “ KING CORO”, “APProved bY BSI” and “Licence No 41231” with a counterfeit Kitemark
•The cable is marked “CCC YF 227 IEC 53(RVV) 3x0.75mm2  300/500V GB5023.5-1997 MADE IN CHINA”, but actual conductors are less than 10% of rated value!
•The outer covering of the cable and the insulation on the conductors is so weak that it can be easily peeled off using finger nails only.


Some counterfeit plugs have pins which are the wrong size, too short, too long, too thick and too thin.

This lead (shown far left compared with a genuine BS 1363 plug) was bought from an ebay seller in May 2011 had a plug that was completely the wrong size and was fitted with a fuse which was so loose it rattled!  In addition, the fuse (which was itself counterfeit, and not compliant with BS 1362) was the wrong value for the lead type. 
The line wire was connected directly to the pin, THE FUSE WAS NOT CONNECTED!!!   
We have also seen this plug on


This counterfeit plug (shown right) was supplied with a charger purchased through  It is marked with a BSI kitemark and has illegal earth sleeving.  It also has power pin sleeving which is too long.  The moulding is of poor quality, and the strain relief has failed.  It was fitted with a counterfeit fuse, which, unlike the plug above, was connected.    
The cable to which it was attached claims to be 3 core 0.75mm2
(24x 0.2mm strands), but the strands are actually only 0.1mm.  
A genuine 3 core 0.75mm2 cable is also shown for comparison.

The main purpose of a plug fuse is to protect the flex against a short circuit.  Genuine fuses contain a filling of silica sand which acts to prevent arcing when a fuse blows.
  Counterfeit fuses are not filled in this way.     A UK Government warning explains that counterfeit fuses can explode when they blow! 
Watch this video to see what happens to a counterfeit fuse when the flex connected to the plug is short circuited.

Pictured above, three versions of another type of very dangerous plug.  These plugs have no fuse at all! , All of these were available from various trade vendors on in March 2012.
The plug in the centre was also available from in March 2012.

In late 2015 we are still getting reports of these plugs being supplied through both sites.  All of these plugs have the pins placed illegally close to the periphery of the plug. 

In October 2015 BBC Watchdog had a segment describing how these fuseless plugs are being supplied with ”hoverboard” products!

Sleeve detail

To demonstrate why partially sleeved earth pins are so dangerous we stripped away all of the parts of a socket except the earth contact.  The picture above shows that the earth contact touches only the insulated part of the pin, at the points indicated by the red arrows.
No actual  connection is made to earth!


On the left is another counterfeit plug,  this one, marked with the non-existent brand ‘guida’ was supplied with a charger purchased from Amazon.  You can see an image of the Amazon listing on the Amazon sample page here.

The charger supplied was different from the one offered, and a different mains lead was supplied.  (The one pictured in the listing had a cloverleaf connector also with an illegal plug having an insulated earth pin). 

This plug appears similar to the one shown above but without a partially insulated earth pin.  However, it is still a counterfeit!  Close inspection reveals that what appears to be a BSI Kitemark moulded into the plug is in fact not a Kitemark, the approval mark next to that claims that the plug is approved by STGS, a fictitious organisation.  The cartridge fuse fitted to the plug claims to be a BS 1362 13A fuse, but is also counterfeit.

We continue to see these fakes being sold online!

In 2008 the BBC “Watchdog” programme took Amazon to task for selling counterfeit and illegal goods.   Brian McBride (then Amazon UK managing director) was interviewed in that programme, stating: “we do not tolerate counterfeit products ..  we take them down as soon as we find out about them”.  Really?  Only one of the counterfeits we have bought from Amazon has been recalled!!!
The BBC page linked above describes the Amazon segment of the programme.
Some of the illegal product types which Amazon assured the BBC would be removed continue to be sold on Amazon more than seven years on!  Here is a compilation of 10 illegal pepper spray products captured on the website in March 2014: Amazon Pepper Spray and also an example of a captured page from Amazon (April 2012) offering  CS Spray  

In October 2014 PlugSafe became aware that (Amazon, not a marketplace seller!) were offering a pistol which uses percussive cartridges to fire shots of pepper spray.  A PlugSafe volunteer placed a test order on and the pistol was duly delivered from the Amazon warehouse in Ridgmont, Bedfordshire, it was delivered via Royal Mail (an offence in itself as pepper spray is a prohibited item banned from sending in the mail).  The delivery address was a house whose letter box is in full view of the street, the package was left hanging out of the letter box (fully accessible) by the postman, as it would not pass through!  The package was passed, unopened, to officers from Police Scotland, in the presence of a local MP.  Police Scotland launched an investigation, confirming that the product was a prohibited weapon.  Subsequently, in the summer of 2015, resumed sales of the pepper spray pistol!  We contacted the Guardian Newspaper and they also made a test purchase of the illegal pistol which, as with the first one, was delivered from the same Bedfordshire warehouse.  In December 2015 The Guardian published a front page article about Amazon’s sales of illegal weapons.  Despite having been exposed yet again, continued to support the sale of illegal weapons and by early March 2016 PlugSafe monitoring found over 30 separate listings of pepper spray products on, including many high-strength, high capacity aerosols designed for use against wild bears.  This was followed by a second article on Amazon’s illegal weapons sales in The Guardian, this included details on weapons purchased from Amazon which feature in two recent  trials involving the killings of teenagers Becky Watts and Bailey Gwynne.

Amazon UK continues to allow illegal and dangerous electrical goods to be sold through its marketplace, here is an annotated compilation of some samples of such products among the many which were listed at the beginning of March 2014, both this and other examples were included in evidence to the parliamentry committee looking at consumer rights.   In February 2016 we purchased a sample of this cord set sold directly by and featuring an illegal ‘guida’ brand plug with false approval marks. The Amazon offer clearly shows a plug with partially sleeved earth pin (therefore illegal) and the test purchase, direct from Amazon, confirmed that the supplied product is the illegal item offered!

We have made a similar March 2014 annotated compilation of eBay sample listings (all still available in June 2014!!!).  Click here for an earlier gallery of sample listings for products which include illegal plugs, these are amongst the THOUSANDS of listings which ebay has removed since this campaign started in August 2011.  The listings removed included over 140 of the completely illegal plug without a fuse!  See samples of the deleted listings)

Although we wish eBay would prevent illegal plugs ever being offered for sale on their website we would like to acknowledge that, unlike Amazon, eBay take prompt action when informed of illegal listings by Trading Standards Departments.  However, we have had absolutely no success in reporting illegal listings directly.  eBay do provide a report button on every listing, but, in our experience, take no action when a product is reported via that method!

Loophole in BS 1363

There is a problem in BS 1363 which allows extension sockets to be manufactured with the earth hole placed too close to the edge.  Most multi-way portable socket outlets exploit this loophole and permit the insertion of an inverted plug into the earth pin only, thus opening the shutters of the current carrying contacts.  This is a clear danger as can be seen from these photos.

It is to be hoped that this oversight will be corrected at the next revision of BS 1363.  Until then it is important to ensure that children are not allowed access to this type of extension.
