Asset Depreciation in BTR: Using Comparison Reports to Win Deposit Disputes

Fair wear and tear is one of the most contested concepts in residential tenancy law — and it's where most BTR deposit disputes are fought and won or lost. Understanding how to document asset depreciation accurately, apply wear and tear allowances correctly, and present comparison evidence compellingly is essential for any BTR operator seeking to protect their asset values.

Understanding Fair Wear and Tear

Fair wear and tear refers to the reasonable deterioration of a property and its contents through normal use over time. Landlords cannot charge tenants for damage that falls within this definition. The challenge is that 'reasonable' is inherently subjective — and adjudicators make decisions based on the evidence presented to them, not on abstract principles.

Factors that influence wear and tear assessments include the age of the item at the start of the tenancy, the length of the tenancy, the number of occupants, and the quality of the original fitting. A brand-new carpet in a 4-bed HMO will show more wear after one year than a 2-year-old carpet in a single occupancy studio.

Asset Depreciation Schedules

Sophisticated BTR operators maintain asset depreciation schedules for all major items in their apartments. These schedules set out the expected lifespan of each asset category — flooring, kitchen units, appliances, bathroom fittings — and allow the operator to calculate a pro-rata charge if an asset is damaged before the end of its expected life.

• Carpets: typically 7–10 years expected lifespan
• Hard flooring: 15–20 years expected lifespan
• Kitchen units: 20+ years expected lifespan
• White goods: 8–12 years expected lifespan
• Bathroom fittings: 15–20 years expected lifespan
• Painted walls: 3–5 years between redecorations

If a carpet was new at the start of a 2-year tenancy and has been damaged beyond fair wear and tear, the chargeable amount is the replacement cost minus 2 years' worth of depreciation based on a 7-year lifespan. This approach is transparent, defensible, and accepted by all major deposit protection schemes.

How Comparison Reports Change the Game

Before AI comparison reports, presenting asset depreciation evidence meant manually juxtaposing check-in and check-out photos in a Word document, with written explanations of what had changed. The process was time-consuming, the output was inconsistent, and busy adjudicators often found it hard to follow.

AI comparison reports change this entirely. The system automatically places the check-in and check-out photos of each item side by side, generates a written assessment of the observed difference, scores the severity of the change, and calculates the applicable depreciation charge. The output is a structured, professional document that tells a clear and unambiguous story.

Building an Unassailable Evidence Pack

The most successful BTR operators approach deposit disputes like legal cases. They build an evidence pack that includes: the original inventory with check-in photos, the comparison report with AI-generated assessments, the applicable depreciation schedule, quotes or invoices for any repair or replacement work, and a summary cover sheet showing the total deduction claimed.

Adjudicators are significantly more likely to find in the landlord's favour when the evidence is this well organised. The AI-generated comparison narrative removes the element of subjectivity — it's no longer the landlord's word against the tenant's, but an objective photographic record with a written assessment.
