My mum died recently and I'm selling her house, but I live 300 miles away so will be very dependent on the estate agent to hold the keys, conduct viewings and make sure the house is kept properly secure. I'm meeting with the agent next week to discuss logistics, but it would be useful to know in advance what to expect - do they normally have something in the signed agreement about their responsibilities towards security? (Perhaps I'm being paranoid, but I have visions of young agents 'borrowing' the keys on a Saturday night and making clandestine visits to impress their girlfriends/boyfriends).
