Why is my Vauxhall Zafira Life's engine making a ticking sound?

I have noticed that my Vauxhall Zafira Life's engine has started making a ticking sound when I start it up in the morning. It goes away after a few minutes of driving but it's concerning me. What could be causing this and should I be worried?

The ticking sound could be a sign of low oil level. Check your oil levels and top up if needed.

It could also be a problem with the engine's timing belt. Get it checked by a mechanic to be safe.

Another possible cause could be a worn-out valve lifter. It is recommended to get it replaced if this is the case.
