I want to combine my spotlights with under-cabinet lights, but the under-cabinet lights don't have an earth cable.

I have just put up these spotlights in my kitchen - https://www.screwfix.com/p/lap-chaac-fixed-fire-rated-led-downlight-polished-chrome-5-5w-600lm/943re

I want to add these under-cabinet lights so that it's all on one circuit (press the light switch and both types of lights come on). https://www.toolstation.com/sensio-...tm_term=2323955265649997&utm_content=Lighting

I could be wrong but it looks like the under-cabinet lights don't have an earth cable. The spotlights use a twin and earth cable. What shall I do?

Do all the lights have to be connected in any particular order? I will probable get 2/3 under-cabinet lights, can they be slipped into the middle of the daisy chain?

Is there anything else I need to know?

Thank you.

Your Toolstation link does not work.

I see "sensio" in the link - if it's for the Sensio mains under cabinet strips, which seem able to be daisy chained with (2-core?) cables they supply, then you couldn't subsequently feed other lights that require an earth from the remote end of the strips. But you don't need to do that.
You can connect the input wire to the under cabinet chain from anywhere on the chain of spotlights, or into the cable feeding them if necessary using a maintenance free junction box.

No but the integrity of the cpc (earth conductor) should remain throughout - except a short flex (as supplied for the under unit lights) is permitted without an earth conductor.
