Tracing a live, electrical wire

We had an old boiler removed but they left the live electrical cables (long, boring story).

We now basically have the live electrical wire sitting under floorboards. It's been taped up and made safe with a marking on it saying 'Live'. Just in case.

The problem we have is without lifting carpets and floorboards etc we cannot trace it back to the consumer unit. Is there a device that we could put on the disconnected end (as that's easy to get to) that effectively makes a tone, or lights up or something so we can tell where it enters the consumer unit and disconnect it? I know there is a similar device called a toner that works on phone lines, but does anyone know of one that works on electrical wires?

It's a job for a proper qualified electrician , some things like ' live' electric cables are a specialist subject

Totally appreciate the comments. The wire was made safe by a retired electrician and any future work will be done by a fully qualified electrician, but that's not the point of my post.

you can put a load, such as a lamp, on it. Then go to the CU and turn off the breakers or pull out the fuses until it goes off.

most likely it will be part of the downstairs socket ring, and probably spurs off a nearby socket. It is possible, but most unlikely, that it has its own circuit running to the CU.

"taped up" is not remotely professional.

You can buy a cable detector from the internet or your local machine mart or screwfix. With this, you can trace it back to a junction box that might be under your floor. I use a brennenstuhl digital detector.
