I may be mistaken here but I thought Building Regs required that sockets and switches be positioned so that anyone (including those with limited movement) can easily use them.  I didn't think there was a specific height required.

I know the OSG suggests between 450 to 1200 but most houses seem to have the sockets around 250 off the floor.  To have them at 450 would look horrible!!

So, is this a rule (the 450 bit) or is it just a recommendation??

Does anyone know  ???

The building regs cover rooms likely to be used by those who are disabled or infirm. Hence the 450mm so grandma doesn't have to bend down to plug in the TV etc. This would cover all sockets in most new houses as they can't discriminate against those they amy offer them to. Hotels and even sitting rooms in normal houses would be covered too. That's why the IEE regs just go for a 450mm min at the recommended height. Normally for retro-fits and additions installers will just match the existing outlets.

Time Mr Inspectors visit for after the plastering - then he'll never know that above and below each socket you have another box ready to be uncovered to take the accessory at the height you want...
