TL;DR

Property inventory reports London landlords commission are the written and photographic record of a rental’s condition at the start and end of a tenancy. In a market where the average deposit dispute claims over £600, the inventory is the single document that determines whether a landlord wins or loses the case. AIIC-accredited clerks produce the format that scheme adjudicators (TDS, DPS, mydeposits) recognise as authoritative. This guide explains exactly what a professional inventory contains, when the law requires one, what they cost, and how to commission one in London.

What is a property inventory report?

Property inventory reports London landlords use are the written, photographed, and dated record of a rental property’s physical condition at a specific moment in time. The report covers every room, every fixture, every appliance, and, in furnished lets, every piece of furniture and item left in the property for the tenant’s use.

In England, no statute requires a landlord to commission an inventory report. The legal requirement sits one step removed: the Tenancy Deposit Schemes require landlords to protect deposits, and when a deduction is disputed, the scheme adjudicator decides who is right based on the evidence presented. Without a professional inventory, a landlord has no evidence that meets the adjudicator’s standard.

The result is that an inventory is operationally compulsory even if not statutorily required. Industry data from the Tenancy Deposit Scheme and Deposit Protection Service consistently shows that landlords who present a professional, AIIC-format inventory at adjudication recover deductions at a far higher rate than those who present photographs, text messages, or self-produced lists.

The professional body that sets the methodology for this work is the Association of Independent Inventory Clerks (AIIC). AIIC-accredited clerks follow a standardised six-section format, use a defined vocabulary for describing condition, and produce reports that scheme adjudicators have been trained to weight as authoritative.

The six sections of a professional inventory report

A complete AIIC-format inventory report contains six distinct sections, each with a specific evidential purpose. Understanding the structure matters for any landlord who wants to commission one, and for tenants who want to know what they’re signing.

1. Cover page

The cover page captures the property reference, full address, inspection date, clerk’s name and AIIC membership number, landlord and tenant details, and the type of report (check-in, check-out, mid-term, or condition-only). It establishes the document’s authenticity and chain of evidence. Without these fields, an adjudicator cannot verify that the report relates to the disputed property and tenancy.

2. Schedule of condition

The schedule is the heart of the report: a room-by-room, fixture-by-fixture written assessment using AIIC’s standardised condition vocabulary. Terms like “fair wear and tear,” “soiled,” “marked,” “scratched,” and “damaged” carry specific meanings in AIIC methodology. A scuff is not a scratch; a scratch is not damage. Adjudicators read these terms with their AIIC-defined meanings in mind, which is why self-produced inventories using everyday language tend to fail at adjudication, the language is too imprecise to support the deduction being claimed.

3. Photographic evidence grid

Every written observation in the schedule cross-references to a numbered photograph. A noted scratch on the hallway floor links to a specific photo of that scratch. The photo grid is what allows an adjudicator months later to see what the clerk saw, in the lighting the clerk saw it under, at the angle the clerk saw it from. Photo-only inventories (no written schedule) fail because they have no narrative for the adjudicator to read; written-only inventories (no photos) fail because they have no visual evidence to corroborate the descriptions.

4. Meter readings

Gas, electric, and water meter serial numbers and readings are captured at check-in and check-out, with a photograph of each meter face. This protects landlords from being billed for usage that occurred before the tenant arrived or after they left, and protects tenants from being charged for predecessors’ consumption. For London properties where utility billing disputes are common, this section often resolves a dispute before it escalates.

5. Contents inventory (furnished lets only)

For furnished lets, every item left in the property for the tenant’s use is listed individually: brand where visible, condition, and quantity. A sofa is not just “sofa”, it’s “three-seater fabric sofa, grey, two cushions, light marking to left arm rest.” Detailed contents inventories prevent disputes over missing or substituted items at check-out.

6. Sign-off page

Both landlord (or their agent) and tenant sign the report. The clerk countersigns. Dates are recorded. The signed sign-off page is what gives the inventory its full evidential weight: the tenant has acknowledged, in writing, that they accept the report as an accurate description of the property at move-in. If the tenant disputed any item, that dispute is recorded on the sign-off page before signing.

Check-in reports versus check-out reports

The check-in and check-out reports together form the matched pair on which every deposit dispute is decided. The check-in establishes the baseline; the check-out compares the property to that baseline. Without both, the adjudicator has nothing to compare and the landlord cannot prove damage.

A check-in report is conducted on or just before the day the tenant moves in. The property must be empty of the previous tenant’s belongings, freshly cleaned, and in the condition the landlord wishes to document. The clerk inspects, photographs, takes meter readings, and the tenant signs the report on the day or shortly after.

A check-out report is conducted on or just after the day the tenant moves out. The property must again be empty of the tenant’s belongings. The clerk re-inspects against the check-in report, photographing every changed item and writing each change against the AIIC condition vocabulary. The check-out report does not declare fault or recommend deductions, that is for the landlord to negotiate or for the scheme adjudicator to decide. The clerk’s job is to document what changed.

The two reports must use the same methodology, the same vocabulary, and ideally the same clerk or at least the same firm. Inconsistency between check-in and check-out reports is the single most common reason adjudicators reject a deduction claim. For the full operational difference between the two reports, our check-in report vs check-out report guide walks through every distinction.

Who creates inventory reports

Three groups produce inventory reports in the UK: independent inventory clerks, letting agents, and landlords themselves. Adjudicators weight the evidence from each group very differently.

Independent inventory clerks, particularly AIIC-accredited clerks, produce the format that adjudicators recognise as authoritative. The independence is structural: the clerk has no financial stake in whether a deduction is made, so the report carries no inherent bias. AIIC membership requires training, ongoing professional development, and adherence to the methodology adjudicators expect to see.

Letting agents often offer inventory services as part of a managed letting package. The reports vary widely in quality. Adjudicators sometimes weight agent inventories less heavily than independent clerk reports, particularly when the agent’s commission is tied to the property’s performance, because the agent has a commercial interest in the landlord recovering deductions that the tenant might otherwise dispute.

Landlord-produced inventories are the weakest evidence category at adjudication. Even the most diligent landlord cannot eliminate the perception of self-interest, and most landlord inventories miss the AIIC vocabulary and structural requirements that adjudicators look for. Our inventory clerk guide explores the full picture of who AIIC clerks are and how to hire one.

When inventory reports are legally relevant

The legal relevance of an inventory report sits in three places.

First, the Housing Act 2004 requires landlords to protect tenancy deposits in one of three government-approved schemes (TDS, DPS, or mydeposits) within 30 days of receiving the deposit. The Act does not require an inventory, but the deposit-protection regime cannot function without one.

Second, the Tenant Fees Act 2019 caps tenancy deposits at five weeks’ rent for tenancies under £50,000 annual rent. With a capped deposit, the precision of an inventory matters more, landlords cannot rely on a generous deposit buffer to absorb minor disputes.

Third, the Renters’ Rights Act 2025 removes Section 21 “no-fault” evictions and replaces fixed-term assured shorthold tenancies with periodic tenancies. Under the new regime, the inventory becomes more important because end-of-tenancy disputes are now the primary moment when condition becomes contested, there is no longer a routine “end of fixed term” exit. For more on what changed, see our Renters’ Rights Act compliance checklist.

What happens without an inventory

The consequences of letting a property without a professional inventory become visible at check-out. There are three failure modes.

The first failure mode is that the tenant disputes a deduction and the deposit scheme adjudicator finds in the tenant’s favour because there is no contemporaneous evidence to support the landlord’s claim. The landlord recovers nothing for damage that genuinely occurred.

The second failure mode is that the landlord, anticipating the first failure mode, releases the full deposit at check-out without claiming for visible damage, because the cost-benefit of trying to claim without evidence is not worth the dispute. The landlord absorbs the loss, which then often appears as a hidden cost in the next tenancy.

The third failure mode is that the tenant claims damage existed before they moved in and the landlord has no check-in report to prove otherwise. This scenario hands the tenant leverage that they would not otherwise have.

Industry data from the deposit-protection schemes consistently shows that disputed deductions split roughly 40% in favour of the landlord, 40% in favour of the tenant, and 20% as a partial award, but those averages mask a much sharper underlying pattern: landlords with professional AIIC-format inventories win the great majority of their disputes, and landlords without inventories lose the great majority of theirs.

Mid-term inspections and condition reports

Beyond the check-in and check-out, two further inventory products serve specific purposes during the tenancy.

A mid-term inspection is conducted partway through a tenancy, typically every six months, to document the property’s condition while it is occupied. The inspection is not a check-out and does not establish liability for any damage observed; it documents condition, photographs any concerning changes, and creates a contemporaneous record that may later support a check-out deduction. Mid-term inspections are particularly important for HMO properties, where multiple tenants and shared spaces create more opportunities for unreported damage. Our mid-term inspection guide covers the cadence and methodology.

A condition report (sometimes called a “schedule of condition”) is a one-off written and photographic record of a property’s current state, commissioned outside the check-in/check-out cycle. Common use cases include preparing a property for sale, documenting condition before a refurbishment, or establishing baseline condition for insurance purposes. The format is the same AIIC six-section structure but without the matched-pair check-in/check-out comparison.

London-specific considerations

Several aspects of the London rental market shape how inventory reports are commissioned and used.

Periodic tenancies under the Renters’ Rights Act 2025 mean that tenancies no longer end on a predictable fixed-term date. Landlords cannot schedule a check-out months in advance; they have to commission the check-out when the tenant gives notice, sometimes with only a few weeks’ lead time. Choosing a clerk with the operational capacity to schedule quickly matters more than in the pre-2025 regime. See our periodic tenancy renters’ rights act guide for the full operational picture.

HMO licensing adds an inspection dimension. Many London boroughs require licensed HMOs to evidence ongoing compliance with property condition standards, and an AIIC-format inventory plus mid-term inspections provides exactly that evidence trail. For the borough-by-borough licensing detail, see our do I need an HMO licence and HMO licence cost guides.

Compliance certificates sit alongside the inventory in any landlord’s tenancy documentation pack. The EICR (Electrical Installation Condition Report) is required every five years; an EPC every ten years; gas safety annually. Many landlords commission these alongside the check-in inventory, on the same day, to minimise tenant disruption. The inventory clerk does not produce these certificates, they require separately qualified inspectors, but a single property-services firm can coordinate the scheduling.

Property size and configuration matter for cost. London is dense with one and two-bedroom flats, but there are also large period houses, garden flats with conservatories, mews properties with awkward layouts, and HMO conversions where bedroom counts exceed what the property’s footprint would suggest. AIIC clerks price by property size and configuration, with size uplifts for houses (typically +15% from three-bed upwards) and supplements for furnished lets and additional rooms.

What property inventory reports London landlords pay for them

London inventory clerk fees follow a fairly stable structure across reputable firms. The pricing below reflects the typical 2026 market for AIIC-accredited clerks working across Greater London postcodes.

Common supplements: – House (versus flat): +15% from 3-bed upwards – Furnished: +£10 – Additional rooms (study, conservatory): +£10 each – Out-of-area (non-London postcode): +£25 – Sunday or bank holiday: +£50 – Peak time (early morning between 9-10 AM): +£50

Bundle savings: Booking check-out alongside check-in (matched pair) typically saves 50% on the check-in. This reflects that the same firm is doing the bookkeeping and scheduling once for what will be two visits, and that having both reports produced by the same firm (often by the same clerk) gives the matched-pair documentation the consistency adjudicators prefer.

Many London firms also offer compliance bundles that combine EICR, EPC, and Gas Safety certificates at a discount, scheduled alongside the check-in to minimise tenant disruption. A full compliance bundle typically runs around £320 versus £340 if commissioned separately.

How to commission an inventory in London

Commissioning a professional inventory report in London follows five steps.

Step one is choosing the firm. Verify AIIC membership of the individual clerks (not just the firm) at the AIIC member directory. Verify the firm’s insurance, particularly professional indemnity cover. Check that the firm operates across the postcodes you let in, some firms cap their service area to specific zones.

Step two is scheduling. A check-in needs to happen on or just before the tenant’s move-in date. Book at least one week in advance where possible, peak season (June, July, August, September) sees diary pressure. The property must be empty of the previous tenant, freshly cleaned, and ready to be photographed in its presentable state.

Step three is the inspection itself. A check-in for a one or two-bedroom flat typically takes 60–90 minutes; a three-bedroom house can take two hours; a four-bedroom-plus property or a furnished let can run longer. The landlord or letting agent does not need to be present, but the tenant typically attends and walks through the property with the clerk.

Step four is the report delivery and sign-off. AIIC clerks typically deliver the report within 24–72 hours of the inspection. The tenant has a defined window (usually 7 days) to review the report and add any disputed observations. After that window, the report becomes the legally referenced baseline for the tenancy.

Step five is storage. The signed report needs to be kept securely until at least six years after the tenancy ends, beyond the limitation period for most tenancy-related disputes. Professional inventory firms typically store the report indefinitely in their own systems, but landlords should also keep their own copy.

Frequently asked questions

Are landlords legally required to have an inventory report?

No. There is no UK statute that requires a landlord to commission an inventory. The legal requirement is to protect the tenancy deposit in an approved scheme. The inventory becomes operationally compulsory because deposit disputes are decided on evidence, and a professional inventory is the evidence type scheme adjudicators recognise.

What’s the difference between an AIIC clerk and a non-AIIC clerk?

AIIC (Association of Independent Inventory Clerks) is the principal UK professional body for inventory clerks. AIIC members complete formal training, follow a standardised methodology, use defined condition vocabulary, and undertake ongoing professional development. Non-AIIC inventories vary widely in quality. At deposit adjudication, AIIC-format reports are routinely weighted as authoritative because the adjudicators are themselves familiar with the AIIC methodology.

How long does an inventory inspection take?

Roughly 60–90 minutes for a one or two-bedroom flat, two hours for a three-bedroom house, longer for larger or furnished properties. The clerk inspects every room, every fixture, every appliance, takes meter readings, and photographs everything they describe.

Do I need a new inventory for every tenancy?

Yes. Each tenancy needs its own check-in and check-out report, because the legal baseline for a deposit dispute is the condition documented at the start of that specific tenancy. An inventory from a previous tenant does not establish baseline condition for the next one.

Can I produce my own inventory and save money?

You can, but at deposit adjudication the evidence is weighted much lower than a professional AIIC report. The saving on the inventory fee, typically £120–£200, is dwarfed by the average disputed deduction, which TDS data puts at over £600. Self-produced inventories tend to fail at adjudication because they use everyday language rather than AIIC condition vocabulary, miss structural sections like meter readings and signed sign-off, and carry the inherent perception of landlord self-interest.

How quickly can a London inventory clerk attend?

Most established London firms can schedule within three to seven days for routine bookings. Same-day or next-day attendance is sometimes possible at peak surcharge rates, but is not guaranteed during peak season (June–September). The shorter notice the tenant gives, the harder it becomes, which is one of the operational consequences of the Renters’ Rights Act 2025 periodic-tenancy regime.

What if the tenant disputes the inventory?

The tenant has a defined window after the report is delivered (typically 7 days) to raise disputes in writing. Disputed items are recorded on the sign-off page. Genuinely contested items can be reinspected by the clerk or by a different clerk if the firm offers that. After the dispute window closes, the report becomes the legally referenced baseline.

Where can I commission property inventory reports London-wide?

Click Inventories produces property inventory reports London-wide, every London postcode (EC, WC, E, N, NW, SE, SW, W). Out-of-area postcodes outside Greater London attract a +£25 surcharge. Same-day booking, weekend and bank holiday attendance, and peak-hour scheduling are all available subject to clerk availability.
