The 7-Day Inventory Challenge Window: How to Protect Yourself

The inventory is the document that ends most deposit disputes — and starts a few. Under the framework that runs alongside the Renters' Rights Act 2025, the 7-day challenge window is the legal mechanism that turns a one-sided document into a binding record of the property's condition at start of tenancy. Used correctly, it removes most of the ambiguity that adjudication panels have to wade through at end of tenancy.

Used incorrectly — or not at all — it leaves you with no agreed baseline and a much weaker case for any deductions later.

What is the 7-day challenge window?

When you provide the tenant with an inventory at the start of the tenancy, the tenant has 7 days from receipt to raise any objections, corrections, or disputes. If the tenant does not object within that 7-day window, the inventory is deemed accepted as an accurate record of the property's condition.

This is the rule that makes inventories enforceable. Without the 7-day window, every disputed scratch on the skirting board would turn into a he-said-she-said. With it, the tenant has a clear, time-limited opportunity to flag inaccuracies — and once that window closes, the document stands.

How does the 7-day clock start?

The clock starts on the day the tenant receives the inventory. That is not necessarily the day you sent it.

In practice, you should:

1. 1Send the inventory by a method that produces a delivery confirmation — email is ideal, or first-class post with a record of posting
2. 2Note the delivery date
3. 3Diarise the end of the 7-day window

For email, "receipt" is the moment the email lands in the tenant's inbox — usually the same day you send it. For post, "receipt" is the day the letter is delivered, which is typically two working days after first-class posting.

Best practice is to ask the tenant to acknowledge receipt by email. Once you have that acknowledgement, the start date is unambiguous.

What counts as a valid challenge?

A valid challenge is a written communication from the tenant identifying a specific item or condition that is wrongly recorded. For example:

• "The carpet in the second bedroom has a stain you have not noted."
• "The kitchen tap leaks — you have recorded it as 'good working order'."
• "There are three broken slats in the lounge blind, not one."

A vague "I disagree with the inventory" is not enough. The tenant should be specific. If the tenant does raise a specific objection within the 7-day window, you should respond promptly — either accept the correction and amend the inventory, or document why you do not accept it. Photographs at start of tenancy are decisive here.

What if the tenant says nothing?

If the 7-day window passes with no written challenge, the inventory is deemed accepted. At end of tenancy, you can rely on it as the agreed condition record.

This is important to put on the record. Best practice is to send a short note on day 8 saying:

"As I have not received any objections to the inventory I sent on [date], it is now deemed accepted as the record of condition for this tenancy. A copy is attached for reference and will form the basis of the end-of-tenancy comparison."

This puts a date on deemed acceptance and gives you something to wave at any future challenge.

What should an inventory contain?

A robust inventory has three layers:

1. 1Item list — every item in every room, including fixtures, appliances, and furniture
2. 2Condition notes — the state of each item ("good order", "minor wear", "scuff to lower right corner")
3. 3Photographs — high-resolution, dated, of every room and every item that could later be disputed

Photographs are the single most important element. A written inventory without photos is hard to defend at adjudication; a written inventory with timestamped photos is hard to challenge.

Include meter readings (gas, electric, water) and a record of keys handed over. Note the condition of smoke and carbon monoxide alarms — these are required by regulation and proof they were tested at start of tenancy is useful evidence.

What happens at end of tenancy?

At end of tenancy, you carry out a check-out inspection and compare to the inventory. Any differences that go beyond fair wear and tear can support a deduction from the deposit — but only if the start-of-tenancy condition is documented and undisputed.

The tenant can still challenge specific deductions at the end. What they cannot do — once the 7-day window has passed — is reopen the original inventory and argue, for example, "actually that scratch was already there when I moved in". The deemed-acceptance rule closes that off.

Practical workflow

To make the 7-day window work for you:

1. 1Carry out the inventory on the day of move-in, with the tenant present if possible
2. 2Take photographs of every room and every notable item
3. 3Send the written inventory and photographs to the tenant within 24 hours
4. 4Ask the tenant to acknowledge receipt
5. 5Diarise the day-8 deadline
6. 6On day 8, if no challenge has been raised, send the deemed-acceptance note
7. 7Store the inventory, photographs, and deemed-acceptance note with the tenancy file
