I would agree but remember low voltage = 50 ~ 1000 Vac up to 50 Vac is called extra low voltage however many lighting manufacturers don't seem to follow the international convention. So you need to read carefully.
Extra low voltage comes in three flavours. SELV must NOT have an earth, PELV must have an earth, FELV can be either. The problem is where LV and ELV wires run together the LV and induce a voltage onto the ELV cables they should be a meter apart. With PELV the earth link means no real problem but with SELV (S stands for separated) you can end up with nasty voltages on the isolated cables.
In Wales it needs LABC notification, but not in England under Part P building regulations. You need to be careful what you select.
