Hi! Just wanting some advice regarding insurance prior to buying a house. I'm in the middle of a buying a house and I've been advised by my mortgage advisor to get a building and contents, life, income protection and critical illness cover. Are these all necessary? I've been given a quote of around £150/month for the lot and it just seems a bit excessive esp for a solo buyer, no dependents. Any thoughts or advice would be appreciated. Thanks!
