You can get Reinforcing rod earth clamps, I would suggest going this route first as it is the easiest option, find a location away from other supplies/services, LED Lights, Heat pump etc, and dig into the concrete preferably without a concrete breaker to save compromising the structure, the reinforcing should only be 50mm (2") below the surface of the concrete, you will have to expose the whole surface of the bar to get the clamp on, attach at least a 16mm earthing cable and make good with a resin concrete compound to protect the reinforcement, run this back to the fuse board main earth terminal.
It is quite normal for the clamp not to be accessible in earthed RC structures.
