Insuring a project

[FailHere]

Probably a daft question, but I'm about to exchange on a conversion project and need to get insurance. Currently it's not classed as residential and I need to get buildings cover for it during the conversion process (conversion will be minimal, just adding a bathroom and moving the kitchen to a bigger room). Looking at self-build cover, but not sure if this is the most appropriate.

Any recommendations?

Many thanks for the advice, I've got it sorted now.
