Home insurance - what are people paying on average?

Recent quote of €400 from Allianz for house we are buying:
Rebuild costs for 3 bed mid-terrace - 250k
Contents - 25k
Specified items - 5k
Accidental Damage included
Excess €250
New customer, includes online discount and discount for also having car insurance
 
Hello, could you please clarify about the specified items ? Do you have a particular policy for these items or are they included with the rebuild and contents and with the same company. I also don't want to get annual valuations but also want them covered worldwide ? Many thanks
