Hanworth walls, not generic walls
We expect often with surface conduit — and precast concrete panels and dense blockwork — which is why London Borough of Hounslow kerb rules get settled before the van is loaded in TW13, and we carry the anchors, through-fixings and long bits that match. The mistake we spend most time undoing here is drilling blind into a panel with reinforcement or a buried cable behind it on these streets — measured on the walk in from Feltham (South Western) rather than assumed from a map.
