Insurance arranged by FH with his own company

Hi
I own a leasehold flat in a converted house.

I have just been sent a demand for payment of buildings insurance and have noticed that the insurance company is different to that on last year's demand.

Looking online I have discovered that this new company was disolved last year and has been set up again under the same name with a new address. It is a company that deals with commercial insurance and not residential properties. My freeholder appears to have links with this company. Should I be concerned about this? How can I find out more information?

Thanks in advance
