There’s no such thing as a “Hue Hub,” so I assume you mean a “Hue bridge.”
So, then yes, Hue bulbs that are sold in the kit with Hugh bridge are paired at the factory with that particular bridge so that the person buying them will have an easier setup. Consequently, they cannot be paired to a SmartThings hub until they have been reset.
The problem is that unlike a number of other zigbee bulb brands like Osram, Hue does not have A process for resetting an individual bulb using a blink method.
Consequently you have to get another device and use that to reset the bulbs.
In the US, people mostly use the Lutron connected bulb remote, but I don’t think it is available in the UK yet.
