What it really means is that new equipment will have to work satisfactorily on a range of voltages from 207V (230-10%) to 253V (230+10%) but that the RECs don't actually have to change anything. Incandescent lamps will still be different for different countries/areas - as they are now.
According to the current Electricity Supply Regulations, and the draft of The Electricity Safety, Quality and Continuity Regulations 2001, the limits for HV supplies in the UK are
132-400kV plus or minus 10% below 132kV plus or minus 6%
