Building insurance

Ballygaddy

I am a 50 % co owner under the Do it Yourself Shared Ownership scheme. The Freeholder is a Social Landlord owns the block of flats, we have a flat. The other shared owner is a different Social Landlord, therefore our Landlord. We pay service charges to the Freeholder, which includes a provision for Buildings Insurance. I have discovered that the rent I pay to the Landlord, other co owner not the Freeholder, includes a provision for buildings insurance also. So it looks like I am paying for 2 lots of building insurance. Is this correct? And in the event of buildings insurance claim, which building insurance would I claim from, the Freeholder or the Landlord? I am thinking the Freeholder as they own the building. Many thanks in advance for any advice or comments.
