Deposit-related disputes very often turn on this exact question: was the damage in the property normal wear and tear (which a landlord cannot charge for), or damage beyond that standard (which can justify a deposit deduction or a claim)?

How It's Assessed

Practical takeaway: Photograph the property (dated) at both the start and end of every tenancy. Without a documented "before" state, it's very difficult to prove damage exceeds normal wear and tear.
