Inaccessible joint box... Compliant or not?

[DNS1]

Hi guys,

Moved a door from one end of a wall to the other, bricked up the hole and now moving a 1 gang light switch so it's next to the new door.

The easiest solution is to extend the cable from where the switch used to be, cables and joint box chased into the wall and plastered in.

How can I make this compliant?

Obviously I'm not about to plaster in a standard junction box, but can I use a rated enclosure and Wagos?

I had this with my college lecturer who reckoned that some London institute needs to approve them first.
Until then they don't comply. Whereas crimping the connection's has been tested by this place (I can not remember the name though).

I thought wagos was approved by the company only. And are not going to be compliant until the new regs come into force in January

When exactly do new Regulations and amendments come into force?
If you issue an EIC stating that the work complies with BS7671 as amended to 01/01/12, would that not be acceptable, even if the EIC was issued in 2011?
However if the cables are outside of a safe zone, unless they have an acceptable method of additional protection, they would be a departure, and the designer would have to attest that what ever method is used, would offer the same degree of safety as would be achieved by compliance with the Regulations.
