Thank you. I need to have the new cable routed through the kitchen so my plan is to use this stuff https://uk.rs-online.com/web/p/flexible-tubes/3680182/ as a conduit (8mm internal dia) following the wall behind the cupboards. My next door neighbours have had upgrades and the cabling goes up around doors etc and looks more diy than pro. I would rather it stayed at floor level and mostly out of sight.
