| cat 5 utp|
I wish to install cat 5 (Unscreened) utp for internet broadband and network/phone transmission, however, I am running the cable in the same trunk as mains cable (240v) and i'm unsure if the emf's generated from mains will affect data transmission or cause problems with interference, should I use screened cable instead if so what type? Thank you in advance for any advice offered.

It is better to keep as much distance from power cables as possible than to use a shielded cable. I'm not exactly sure what do you refer to as trunk, but you should not bundle low voltage and power cables together.
Since most housholds do not have powerful electric appliances that constantly switch on and off, I do not think you will experience any problem at all. In any case, the interference is normally going to be on frequency so much different (lower) from that of Ethernet network signal, that it can hardly affect the network's operation is any way.
