Is this safe?

[Tre390]

Hi everyone. I just had an electric toilet seat installed (bidet - warms and shoots water, heats seat, etc). I think some protection was installed on the cable run (rcd?). However I noticed under the cistern some tape was used with the toilet seat cable and main electrical supply.
Is this safe?
Here's a picture:

Thanks to anyone who can help.

Maybe the sparky put the supply in and never came back once the toilet was installed, and the wetpants (plumber) connected it?

Mind you, would the wetpants bother taping it?

Yes. But he would use gaffa tape.

more like sellotape. a plumber would think gaffer tape was a device to shut his boss's gob.
