Thanks all.
I had the landing boards up and found the pile runs directly while the cable diverged to 4" into another run of notches by the next joist, so I'm fairly happy.
I've added Screwfix Protecta plates over each, took 2 per notch as I've wide joists.
I've replaced cooker/socket...
I have a 30+ year old discoloured surface mount cooker control unit. The 13A socket powers my all-gas cooker (clock & ignition), the high current side hasn’t been used for decades but I'm buying a dual fuel cooker (4.4kW) and want to change to a nice new cooker switch.
I have period tiles floor...
