it's a requirement in new dwellings, so all persons including those with restricted reach can easily use them. Habitable rooms only, so kitchens and garages not included, unless the build is for the use of those with restricted reach.
So if you are replacing socket-outlets or adding on to existing circuits or even re-wiring, no requirement needed in old dwellings.
Of course it must still comply to BS7671:2008.
Hope this has answered your question
it comes under the auspices of the building regs, not the wiring regs (I believe, although I stand to be corrected). As such this applies to new builds, even if it is a 4th floor flat with no disabled access!
that leaves a grey area though as to wether this applies to extension works, renovations or rewires. It wouldn't apply if, for example, a new socket was being aded to your living room.
Many thanks for everyone's input - appreciated. We have had a new dormer put in our roof which will give us a new bedroom + an en-suite off an existing bedroom. My impression from the replies is that as this is not a completely "new build" the requirement re heights of switches etc does not apply. Am I right?
Should not need to be!
Requirements are as previously stated, If you are installing a new circuit will need electrical installation cert. If building controls are involved with dormer, you should have also notified them of any new circuits being installed and the en-suite electrics, ie lighting and fans etc... Will also need to comply to part p of building regs and notifiable. Unless you are using a domestic installers scheme registered electrician. Then they can complete all the paper work for you.
as you can see from the replies above, this is far from clear cut. I would say no, but I think some of the others would disagree. my get out with all this when I am working is if the customer doesn't want sockets at these heights I mark it on the installation cert that they have requested not to have sockets at this height (wether that would really work as a get out remains to be seen!)
for example I am about to rewire a grade 2 listed property and having sockets at the required height would look all wrong and would involve cutting into beams which I suspect would contavene the regs for the listed building, but finding regs that contradict each other is nothing new!
A bit of clarity is required here as far as I can see it johntrue does not need to have his sockets between 450mm-1200mm from FFL as this requirement is for new dwellings, does an extension classify as a new dwelling and does a rewire have too? unless it was previously wired as a new dwelling therefore a level of compliance that is no worse?
1. Part M applies to newbuilds and complete renovations. The later meaning you gut the place and start again.
2. Part M DOES NOT apply to rewires or extentions.
as you say, in the latter case, a level of compliance that is no worse than the existing. For example it is no longer permissible to put sockets in skirting boards so new sockets in skirting boards where existing are 25mm above does NOT comply.
