Bedroom rated or sum insured house insurance?

[Olivea17]

Our mortgage broker has quoted us for building survey cover upto £1,000,000. I don’t think we need to be insured upto that given the house is worth under half of this. My first question is: should we ask for bedroom rated or sum insured insurance? Our building survey has told us the cost to rebuild, excluding site and plot value. My second question is: should we request cover to be the cost quoted by the surveyor rather than the £1,000,000 we have been quoted?

Some just come as a million as standard

I’ve spoken to the broker since and they said they couldn’t change the 1 mil or 75k contents insurance. I’ve found a quote myself for cheaper so may go with them instead. Thank you.
