righty, can someone ring up one of your schemes to find out the correct answer,
this is where i'm at as quoted from Part M building regulations page 12/87
http://www.planningportal.gov.uk/uploads/br/BR_PDF_ADM_2004.pdf
it says,
Where the requirements apply
0.1 the requiremtns apply if:
a. a non-domestic building or a dwelling is newly erected;
b. an existing
NON-domestic building is
extended, or undergoes a material alteration; or
c. an existing building or part of an existing building undergoes a material change of use to a hotel or boarding house, institution, public buiding or shop
...............the regulations then continue onto extendsions etc, but that applys only to newly erected buildings.
check it out for yourself, with this information you can put the sockets at what ever height you want, as long as it was built before ( i dunno 2003?? is it?? ) whether its had an extension on it or not, now if it was a non-domestic dwelling getting extended on an old building, then yeah by the looks it'll need part M taken into account?
that Help any one, or am I just rabbling on 'n' on
