cabtyre 2 m extention max lenght

[Gene]

I cannot find the regulation stating that a cabtyre extention cord needs to be max. 2 meters in lenght, so it means all extention cords longer than 2 m is not allowed in a dwelling , eg for a tv on the wall??

There is no restriction on the length of an extension lead .

If the extension lead is "fixed" into the electrical installation then that becomes a different story - Clause 6.16.1.5 or 6.16.1.10 is maybe what you were thinking of

6.16.1.5 A socket-outlet shall supply only one fixed appliance. The use of
flexible cords of length exceeding 3 m is not recommended. The reason for
this recommendation is an endeavour to ensure operation of the overcurrent
protective device. (See also 6.14.1.4 for luminaires).

6.16.1.10 The wiring between different parts of a fixed appliance that are
installed separately is part of the fixed installation, even where it is supplied
from a socket-outlet, unless such wiring is less than 3 m in length
