A property inventory is the dated record of a property's condition and contents at the start of a tenancy, used for comparison at check-out. This guide covers how to actually build one — room-by-room structure, how to write a condition description that holds up to scrutiny, photo standards, and whether to do it yourself or use an independent clerk. For what the inventory is actually used for at deposit deduction time, see the Deposit Protection Guide — this guide is about producing the evidence, not the rules for using it.
1. Why the quality of the inventory matters this much
At deposit adjudication, the inventory is the baseline everything else gets compared against. Without one — or with a vague, undated, unphotographed one — a tenant can credibly claim any damage was pre-existing, and an adjudicator has no way to determine otherwise. A genuinely thorough inventory isn't paperwork for its own sake; it's the single document that determines whether a legitimate deduction claim succeeds or fails months later, when memory alone is no longer reliable evidence for either party.
Two landlords with an identical damaged carpet at check-out can have opposite outcomes purely based on their inventory quality. One wrote "carpet — fine" at check-in with no photo; their deduction claim fails, because there's no evidence the carpet wasn't already damaged. The other wrote "carpet — light wear, no stains, estimated 3 years old" with a dated photo; their claim for the new staining succeeds, because the baseline condition is genuinely established and the deterioration beyond fair wear and tear is clearly demonstrated. Same damage, same legitimate claim — entirely different outcome, purely down to inventory quality.
2. Room-by-room structure
Work through the property systematically, room by room, in a consistent order you can repeat identically at check-out — this makes direct comparison straightforward rather than hunting for the equivalent entry later. Within each room, cover the same categories every time: walls and ceiling, flooring, windows and fittings, any built-in furniture, and a specific note on each free-standing item if the property is furnished. Consistency in structure is what makes the check-out comparison fast and reliable rather than a fresh, unguided assessment each time.
For an HMO let room-by-room, the inventory needs a genuinely different scope than a single let: each individual tenant's room is documented and signed off by that specific tenant, while communal areas (kitchen, bathrooms, living spaces) are documented separately and shared across the whole household's awareness, since responsibility for communal wear and damage is necessarily a shared question rather than attributable to one individual tenant's sign-off.
3. Writing useful condition descriptions
| Weak description | Strong description |
|---|---|
| "Carpet — fine" | "Carpet — light wear consistent with age, no stains or damage, estimated 3 years old" |
| "Walls — good" | "Walls — magnolia, no marks or damage, one small nail hole above fireplace (pre-existing)" |
| "Kitchen — clean" | "Kitchen units — white gloss, no chips or damage, all handles secure, extractor fan functional" |
The pattern across every strong example: specific, objective, and detailed enough that someone who's never seen the room could picture its actual condition. Vague positive descriptors ("fine," "good," "clean") describe your overall impression, not the property's actual state — and provide nothing to compare against at check-out beyond your own memory, which is exactly what an inventory is meant to replace.
4. Photo standards
Photograph every room from multiple angles, plus close-ups of anything specifically noted in the written description (existing marks, appliance condition, meter readings). Ensure photos are genuinely dated — either through metadata preserved by your storage method, or by including a dated document or note visibly in the shot — since an undated photo is significantly weaker evidence if its timing is ever disputed. Consistent lighting and the same approximate angles at check-out make a direct visual comparison far more persuasive than two unrelated-looking photo sets taken under different conditions.
5. DIY vs independent clerk
For a higher-value property, an HMO with multiple rooms, or any situation where you anticipate a higher likelihood of dispute, the independent clerk's cost is usually justified by the stronger evidential position it creates. For a straightforward single let with a tenant you have no reason to expect difficulty with, a genuinely thorough DIY inventory is often sufficient.
6. Getting tenant sign-off
Share the completed inventory with the tenant before or immediately at move-in, and ask them to review and confirm agreement, or note anything they disagree with, within a short window (a few days is reasonable). A tenant-countersigned inventory is considerably stronger evidence than one you compiled and never showed them — it demonstrates the tenant had the opportunity to dispute the recorded condition at the time, not just at the point a deduction is later proposed.
7. Using it at check-out
At check-out, work through the identical room-by-room structure, comparing each entry directly against the check-in record. The consistency emphasised throughout this guide is precisely what makes this fast and defensible — a check-out report that mirrors the check-in structure makes any genuine change in condition immediately obvious, rather than requiring you to reconstruct what the original condition even was. See the End of Tenancy Process guide for the full timing and process this fits into.
8. Common mistakes
"Fine" and "good" describe your impression, not the property's actual, comparable condition.
An inventory the tenant never saw or agreed to is meaningfully weaker evidence than one they countersigned.
Photo evidence needs genuine, demonstrable dating to carry real weight in a dispute.
This makes direct comparison harder and weakens the evidential value of both records.
9. Frequently asked questions
Is a phone-photo inventory good enough, or do I need special software?
Phone photos are genuinely sufficient provided they're organised, dated, and paired with the written room-by-room description — the methodology matters far more than the specific tool. Dedicated inventory apps and software exist and can streamline the process, particularly for larger portfolios, but they're not a requirement for producing evidence that holds up at adjudication.
How long should I keep the inventory after the tenancy ends?
For the duration of the tenancy plus a reasonable period afterward to cover any post-tenancy dispute — see the Landlord Record Keeping Guide for the broader retention guidance this fits into.
Do I need a new full inventory for a renewing tenant, or can I reuse the original?
An update reflecting the property's current condition is worth doing at renewal, even if not a complete rebuild from scratch — conditions change over time, and an inventory that's several years stale doesn't accurately reflect the property's condition at the point the renewed tenancy actually begins.
Is a photo's metadata timestamp enough to prove when it was taken?
It helps, but isn't always sufficient alone, since metadata can be questioned or can be lost depending on how photos are stored and shared. Combining metadata with a visible dated element in the photo itself, or storing photos in a system that independently timestamps uploads, gives a more robust evidential position than relying on file metadata in isolation.
