Hi I'm a newbie drone user. I live in the uk but will be using the drone worldwide as I'm a travel blogger. Any recommendations for reasonable priced insurance? Probably for drone only as found liability insurance with a drone club for £20/yr.

Try your home insurance provider if they offer gadget cover. Most drone insurance companies tend to be restricted for commercial use.

And think about:
Blooging is in many countries commercial  doing,.
At least in case the blog contains ads and links and 'can create' income.
Which means you are not a recreational drone user.
So you may look for a insurance, which would cover professional use.
In special if flying around without licences in these countries, that require some for commercial use of any drone!
