I HATE PDFS WHERE WHEN I TYPE PAGE 39 IN THE VIEWER THE ACTUAL PAGE THAT I GET SERVED UP IS A PAGE THAT IS NOT 39.

I've just noticed the one about the phone line!
What bit about a phone line? I see a bit about a phone point.

 
Part M - page 49 - not noticed this before:

"

h. Switches to double socket outlets are located at the outer ends of the plate (rather than in the centre)."

EDIT: just printing this section to see which other gems have been changed - as I've just noticed the one about the phone line!
I am sure that has always been like that. 450 to the bottom. 1200 to the top.

Usually the front page and contents page do not have page numbers. So page 39 of the document would be page 41 of the PDF if the was 1 front page and 1 contents page.

I know. Still most annoying though.

Best you re-read my last post

 
All the above aside

If not a new build ask the home owner where they want the accessories & put them in .....................simples

The way that I've always understood part m is that only material changes or new builds have to comply with part m and that all other work has to be no less compliant.

So in an existing house adding anything can be done to match the existing heights

I think that was the ambiguity in the old version, the new 2015 version of part m makes it a bit clearer on page iii (try finding that in the PDF without having to randomly scroll)!

Still not definitely 100% clear in plain English though.

 
I think you will find  that the accessibility of electrical accessories is only a minor section of Part M. The main content of the document is building structure. When it refers to material change this is with reference to building structure, as in major extension work, adding or moving rooms etc. Not adding a few extra sockets or a new circuit to an existing installation where the rooms remain in exactly the same layout as before you started.

I had a read of the Welsh version.... when it says a material change it lists several things,

Meaning of material change of use
(regulation 5)
For the purposes of paragraph 8 (1)(e) of
Schedule 1 to the Act and for the purposes
of these Regulations, there is a material
change of use where there is a change in
the purposes for which or the circumstances
in which a building is used, so that after
the change:
a.     the building is used as a dwelling,
where previously it was not;
b.     the building contains a flat, where
previously it did not;
c.     the building is used as an hotel or a
boarding house, where previously it
was not;
d.     the building is used as an institution,
where previously it was not;
e.     the building is used as a public building,
where previously it was not;
f.     the building is not a building described
in Classes 1 to 6 in Schedule 2, where
previously it was;

g.     the building, which contains at least one
dwelling, contains a greater or lesser
number of dwellings than it did previously;
h.     the building contains a room for residential
purposes, where previously it did not;
I.     the building, which contains at least one
room for residential purposes, contains
a greater or lesser number of such
rooms than it did previously; or
j.     the building is used as a shop, where
previously it was not.
And when it comes to extensions

Extensions and material alterations:
dwellings
0.2     Under Regulation 4(3), where any
building is extended, or undergoes a
material alteration, the building work must
be carried out so that after it has been
completed the building complies with the
applicable requirements of Schedule 1,
or, where it did not fully comply with any
applicable requirement, it is no more
unsatisfactory than before.
 
Part M - page 49 - not noticed this before:

"

h. Switches to double socket outlets are located at the outer ends of the plate (rather than in the centre)."

I'll try this again - so who's fitting 2G sockets with the isolation switches at each end of plate to comply with Part M then?

 
Thank you all for the many replies to my original question. To clarify the situation, I am adding power to a new outbuilding (SWA from main consumer board in a house) and therefore it is notifiable work in what aoujld count as a new build.  I am 17th Edition and Part P etc, but not registered with a competent person scheme and therefore will need the job to be signed off.  It has bee some time since I did any work.  Therefore I naturally want it all to be right beforehand.  Yes I can ask the person who will be signing it off, but was just interested in this partiucular sitaution.

 
It is a purpose built wooden shed 6m x 5m with thermal insulation and plaster board.
So it's a small portable building and outside the scope of building control, so nobody will give a flying fig what height you put your switches and sockets, and whether they have inboard or outboard switches.
