Yes, you are required to insure the building so you would need buildings insurance for a buy to let property. You can also get damage insurance as an optional cover to protect your building against any damage which are caused by the tenant. If your property is furnished, we would recommend getting contents insurance but it is not mandatory. It would also be looking at specialist landlord insurance because this can cover legal costs should your tenants bring a claim against you or you need to make a claim against them.
