Claude Sonnet 5 vs GPT-5.5 for property and lettings admin

Guidance excerpt: 'A landlord is responsible for repairs to the structure and exterior of the property and to the installations for the supply of water, gas and electricity, for sanitation, and for space heating and heating water. Repairs should be carried out within a reasonable time, and what is reasonable depends on how serious the problem is and its effect on the tenant. Loss of heating or hot water is generally treated as urgent, particularly in cold weather or where a tenant is vulnerable. Tenants should report problems in writing and landlords should keep a record of what was reported and when.' Three reports arrive on the same Tuesday in November. (a) No hot water at all in a flat let to a tenant in her eighties. (b) A dripping kitchen tap. (c) A bannister that has come loose from the wall on the stairs. Answer using only the excerpt — marked against it. Triage the three, saying for each what makes it urgent or not by reference to the excerpt, what the agent does today, and what the agent tells the tenant today. Say which of the three the excerpt does not clearly cover and what you would do about that rather than guessing.
