Currently the UK still has EU rules on advertising within Children's programmes, that prevent  centre breaks during any programme of 30 minutes or less. Nickelodeon and others get around this by, in a typical hour, listing one programme in a 31 minute slot (can contain ads) and another in a 29 minute slot (cannot contain ads).

And they're not going to change 'em, as the UK channels also broadcast in EU member ROI, where the rules still apply.

Any change to that would uselessly complicate things
