When a deposit dispute lands with an adjudicator, they weren't there when the tenant moved in and they aren't there now. They have exactly one thing to go on: whatever evidence you and the tenant put in front of them. If that evidence is a proper inventory, you're in a strong position. If it's a memory of what the kitchen looked like eighteen months ago, you're not.
Most landlords know they're supposed to do a move-in inventory. Fewer actually do one properly, and the gap between "I took some photos on my phone" and "I have a dated, room-by-room record the tenant signed off on" is exactly where disputes are won or lost.
How a deposit dispute actually gets decided
If a tenancy deposit is protected with one of the three government-approved schemes — the Tenancy Deposit Scheme (TDS), the Deposit Protection Service (DPS), or mydeposits — and the landlord and tenant can't agree on deductions at the end of the tenancy, either party can refer it to the scheme's free alternative dispute resolution service rather than going to court.
The adjudicator's job is narrow: decide whether the evidence supports the deduction being claimed. They're not assessing character or intent — they're comparing documented condition at move-in against documented condition at move-out, and checking whether the difference goes beyond fair wear and tear. Without a move-in record, there's nothing to compare against, and the burden of proof for a deduction sits with the landlord. No inventory generally means no evidence, and no evidence generally means the deduction doesn't stand.
The comparison is the whole case. A photo of a stained carpet at check-out proves nothing on its own. The same photo next to a dated move-in photo showing a clean carpet is the entire argument.
What a proper inventory actually needs
A few photos taken in a rush the day the tenant collects keys isn't a defensible record. To hold up, an inventory needs:
- Every room, not just the obvious ones. Hallways, bathrooms, and outdoor space get skipped more often than living rooms — and disputes happen there too.
- Condition notes, not just photos. A photo shows what something looked like; a note explains what you assessed and why. "Carpet — good condition, no visible marks or wear" is worth more than an unlabelled photo months later.
- A timestamp. An inventory with no date attached is far easier to dispute — there's no way to prove it was taken at move-in rather than assembled after the fact.
- Appliance and fixture condition, specifically. White goods, boilers, flooring, and fittings are where higher-value disputes tend to concentrate.
- Tenant sign-off. An inventory the tenant has seen and agreed to at check-in is far harder to contest at check-out than one they never saw.
- A matching check-out record. The move-in inventory only proves half the comparison — you need the same discipline applied when the tenancy ends.
Why this matters more with Section 8 as the only route
Since Section 21 was abolished, landlords seeking possession because a property has deteriorated under a tenant's occupation rely on Ground 13 — and Ground 13 explicitly requires showing the property's condition has worsened beyond fair wear and tear. That's the same comparison a deposit adjudicator makes, and it depends on the same thing: a documented starting point. An inventory built for deposit purposes does double duty as the evidence base for a Ground 13 claim, if it ever comes to that.
The mistakes that actually cost landlords money
- Doing it after the tenant has already moved belongings in. Furniture and boxes hide the floor, walls, and fixtures you actually need documented.
- No condition rating, just a photo. "Good," "fair," or "poor" against each item turns a photo into an assessment.
- Treating it as a one-off. A periodic inspection partway through a long tenancy catches issues — like a slow leak or unreported damage — while they're still small and while responsibility is still easy to establish.
- Losing track of it. An inventory that exists only as a folder of photos on a phone that gets upgraded eighteen months later isn't evidence anyone can find when a dispute actually happens.
Making it something you'll actually do
The honest reason most landlords skip a proper inventory isn't that they don't understand its value — it's that doing it properly, room by room, with notes and condition ratings, takes real time on top of everything else a move-in involves. That's the gap Slatebase's AI-assisted inventory is built to close: walk the property shooting everything as you go, and AI drafts the room-by-room list and condition notes for you to review and approve, rather than typing it all up by hand. The record still needs your sign-off before it's final — but getting from "walked the property" to "have a defensible inventory" stops being the part that gets put off.
