It must explain the difference between the two routes in plain English, be clear that a notice is not a court order and not an eviction, tell her what to check on the document itself, and point her to free help — Shelter, Citizens Advice, and the council's housing options team. It must not tell her what her legal position is. Then, separately from the letter, list what the agent must verify in the file before sending it.", "output": "# Letter to the Tenant\n\n---\n\nDear Ms [Name],\n\nThank you for calling us today. I could hear how worried you are, and I hope this letter helps to make things clearer. I want to start with the most important point.\n\n**A notice is not an eviction, and it is not a court order.** Receiving a notice does not mean you have to leave your home by the date written on it, and it does not mean you will be removed in two weeks. In England, a landlord who wants possession of a property must follow a legal process: first a notice, then — if you have not left — an application to court, then a court order, and only after that, if necessary, court-appointed bailiffs. Only a court can order you to leave, and only bailiffs acting on a court order can lawfully remove you. Nobody can change the locks or force you out without that. This process usually takes months, not weeks.\n\n**The two kinds of notice**\n\nThere are two different routes a landlord can use, and it will help you (and anyone advising you) to work out which one you have received.\n\n1. **A \"section 21\" notice.** Historically, this has been the type where the landlord does not have to give a reason. However, it only works if the landlord has followed strict rules — for example, protecting your deposit correctly, giving you certain required documents, and holding a licence for the property where one is needed. If those rules were not followed, the notice may not be valid. Whether it is valid is something an adviser can help you check.\n\n2. **A \"section 8\" notice.** This is the type where the landlord must state a reason (called a \"ground\") — for example, rent arrears — and must give the notice period that applies to that reason.\n\nPlease note that the law in this area has changed significantly and continues to change, including which notices are available and what notice periods apply. This is exactly why it is so important that you get advice from someone who can look at your actual document and your tenancy.\n\n**What to check on the document itself**\n\nWhen you look at the notice, or show it to an adviser, check for:\n\n- Whether it mentions **\"section 21\"** or **\"section 8\"** of the Housing Act 1988 (this is usually printed on the notice or the form heading);\n- Whether it is on an **official form** (many notices use a prescribed government form with a form number);\n- The **date it was given to you** and the **date it says you should leave or that proceedings may begin**;\n- Whether any **reasons or \"grounds\"** are stated (numbered grounds usually indicate a section 8 notice);\n- Your **name**, the **property address**, and the **landlord's or agent's name and address** — check these are correct;\n- Whether it is **signed and dated**.\n\nPlease keep the notice and its envelope safe, and keep a note of the date you received it. Do not throw anything away, and please do not feel you must move out simply because the notice names a date.\n\n**Where to get free, independent help**\n\nWe cannot advise you on your legal position, but the following organisations can, free of charge:\n\n- **Shelter** — free housing advice: www.shelter.org.uk or the emergency helpline on 0808 800 4444;\n- **Citizens Advice** — www.citizensadvice.org.uk or your local office;\n- **Your local council's Housing Options team** — the council has legal duties to help people at risk of losing their home, and you do not need to wait until any date on the notice to contact them. We would encourage you to contact them as soon as possible.\n\nAny of these services can look at the notice with you, tell you whether it appears valid, explain what happens next, and set out your options.\n\nPlease do call us again if anything in this letter is unclear, or if you receive any further documents — particularly anything from a court, which you should act on promptly and take to an adviser straight away.\n\nYours sincerely,\n\n[Name]\n[Position]\n[Agency name and contact details]\n\n---\n\n# What the Agent Must Verify in the File Before Sending\n\n1. **The tenant's identity and status** — confirm she is a tenant (or occupier) known to the agency, which property she occupies, and that the agency is entitled to correspond with her about it.\n\n2. **Who served the notice** — check whether the notice was served by this agency, by the landlord directly, or by someone else. The letter must not contradict, undermine, or comment on the validity of a notice the agency itself served on the landlord's instructions.\n\n3. **Any conflict of interest** — confirm whether the agency acts for the landlord of this property. If so, check that the letter is consistent with the agency's duties to its client and that it stays within factual, signposting information rather than advice — and consider whether the letter should come from the agency at all, or whether the tenant should simply be signposted.\n\n4. **What is actually on the file about the tenancy** — tenancy agreement, tenancy type, start date, and any renewals, so the agency does not send a letter that is factually inconsistent with its own records.\n\n5. **Whether a copy of the notice is on file** — if the agency served or received a copy, check what type it is and its dates, so nothing in the letter misstates what the agency already knows (while still not advising her on validity).\n\n6. **Correct contact details** — the tenant's correct name, current address, and preferred contact method, and that sending the letter to that address will not disclose anything confidential to a third party.\n\n7. **Rent account and correspondence history** — check the file for arrears records, complaints, disrepair reports, or prior correspondence relevant to the situation, so the agency is aware of context and does not send anything misleading.\n\n8. **That the letter contains no advice on her legal position** — a final check that the text explains the two routes generically, does not state which notice she has received, does not say whether it is valid, and does not predict the outcome.\n\n9. **That the signposting details are current** — confirm the Shelter helpline number, Citizens Advice details, and the correct local council housing options contact are up to date.\n\n10. **Authorisation and record-keeping** — confirm who has approved the letter under the agency's procedures, and place a copy of the letter and a note of the phone call (date, time, what was said) on the file.\n\n11. **Any safeguarding or vulnerability flags** — the tenant was distressed; check whether the file records any vulnerability that should prompt additional steps (e.g., a follow-up call, or urging immediate contact with the council).", "decider": false, "latency_ms": 32385, "cost": 0.10657, "task_score": 9, "judges": [ { "judge": "google/gemini-3.1-pro-preview", "score": 10, "violates": false, "reasoning": "The response perfectly executes all instructions.

At six weeks, the working assumption must be that he may already be in breach, but that needs verifying against the current legislation — not guessed.\n\n## What protecting it now does and does not fix\n\n**It does:**\n- Get the deposit into a government-approved scheme, which is required in any event\n- Stop the non-compliance getting worse\n\n**It does not:**\n- Cure the original failure, if the deadline has passed — the excerpt says this explicitly\n- Remove the tenant's right to bring a claim, under which a court may order a penalty calculated as a multiple of the deposit\n- Restore his position on the no-fault possession route, which the excerpt says can be affected by non-compliance\n\n\"She'll never know\" is not a strategy the excerpt supports. The exposure exists whether or not the tenant currently knows, and the possession consequence can surface at exactly the moment he most needs the route to work.\n\n## What to do today, in order\n\n1. **Protect the deposit in a government-approved scheme now.** Late is worse than never continuing — the obligation exists regardless.\n2. **Give the tenant the prescribed information.** This is a separate requirement in the excerpt, and it also has to be done within the legislative period; do not protect the money and skip this step.\n3. **Verify the current deadline, the current penalty range, and the current position on late protection** — the excerpt expressly requires this before anyone is advised, and none of those figures can be stated from the excerpt itself.\n4. **Take advice on his exposure** given the six weeks that have passed, including his position on possession.\n\n## Where he needs proper advice, not an agent's view\n\n- Whether the deadline has in fact passed and what that means for him now\n- The current penalty range a court could order — the excerpt confirms only that it is a multiple of the deposit, not what that multiple is\n- The current legal position on late protection and whether anything mitigates it\n- The precise effect on the no-fault possession route, which matters if he ever wants the property back\n\nAn agent's reassurance that \"everyone does it late\" is worthless against a court claim.

The excerpt says loss of heating or hot water is *generally treated as urgent, particularly in cold weather or where a tenant is vulnerable*. Both aggravating factors apply here: it is November (cold weather) and a tenant in her eighties is plainly within \"vulnerable.\" This is the clearest urgent case the excerpt describes.\n\n**Agent does today:** Log the report; arrange a same-day (or soonest possible) contractor visit. \"Reasonable time\" for this problem, on the excerpt's own test (seriousness + effect on tenant), is very short.\n\n**Agent tells tenant today:** That the report is logged, it is being treated as urgent, and when the contractor is expected. Given her age, check in on whether she is managing in the meantime.\n\n## (b) Dripping kitchen tap — **Landlord's responsibility, but not urgent**\n\n**Why not urgent, per the excerpt:** A tap is part of the \"installations for the supply of water,\" so it is the landlord's repair. But the excerpt says what is a reasonable time depends on *how serious the problem is and its effect on the tenant*. A drip is low-seriousness with minimal effect on the tenant, so a longer (routine) timescale is a \"reasonable time\" here.\n\n**Agent does today:** Log it and schedule a routine repair appointment — it does not displace (a) or safety issues.\n\n**Agent tells tenant today:** That it is the landlord's responsibility, it has been logged with the date, and it will be dealt with on a routine timescale, with an appointment to follow. Ask them to report if it worsens (which would change the \"effect on the tenant\" and hence the timescale).\n\n## (c) Loose bannister on the stairs — **Not clearly covered by the excerpt**\n\n**Why this is the gap:** The excerpt lists the landlord's responsibilities as the *structure and exterior* and the named installations (water, gas, electricity, sanitation, heating). An internal bannister is not obviously an \"installation,\" and whether it counts as part of the \"structure\" is not something the excerpt answers.

So while confirming responsibility, I would advise the tenant today to avoid relying on the bannister — but I would present the responsibility question as unresolved until checked, not answered.\n\n**Priority order today:** (a) immediate action; (c) immediate escalation of the coverage question plus a safety warning; (b) routine scheduling.", "decider": false, "latency_ms": 24463, "cost": 0.0919, "task_score": 9, "judges": [ { "judge": "google/gemini-3.1-pro-preview", "score": 10, "violates": false, "reasoning": "The response flawlessly follows all instructions, accurately applying the provided excerpt to triage the issues, detailing actions and communications, and correctly identifying the gap in the excerpt." }, { "judge": "openai/gpt-5.6-terra", "score": 5, "violates": true, "reasoning": "Strong structure and correct identification of the bannister as not clearly covered.

A 9-year-old carpet already recorded as worn throughout has little remaining useful life. On the apportionment approach the adjudicator will estimate what proportion of the carpet's life was left and award roughly that share of the replacement cost — realistically a **small percentage of £340 (plausibly somewhere in the tens of pounds, not hundreds)**, and possibly only a nominal sum if the adjudicator concludes the carpet was effectively life-expired anyway. The landlord should be advised that pressing for the full £340 invites the adjudicator to view the claim as an attempt at betterment, which the guidance expressly guards against.\n\nNote also: the burden is on the landlord. If the evidence doesn't establish the carpet's remaining value, the shortfall counts against the landlord, not the tenant.\n\n# Evidence that would strengthen the claim\n\n- **The signed check-in report** (already held) — this is the anchor: it proves the stain post-dates check-in.\n- **Dated check-out report/photographs** showing the stain, ideally with something establishing scale and location.\n- **Purchase invoice or record for the carpet** — its original cost and quality bear directly on the age/quality/condition assessment and the apportionment calculation.\n- **Evidence a cleaning attempt failed** (or professional opinion that the stain is not removable), justifying replacement rather than cleaning as the remedy.\n- **The written quote** (already held) as evidence of replacement cost, so the apportioned figure has a base.\n\n# Evidence that would sink it\n\n- **Anything suggesting the stain pre-dated check-in** — e.g. tenant photos from move-in showing it.\n- **Undated or unattributable check-out photos** that can't be tied to this room or this tenancy.\n- **Evidence the carpet had no remaining useful life** — if the tenant argues (plausibly, given \"worn throughout\" at 9 years) that the carpet was due for replacement regardless, its residual value could be assessed at or near zero, reducing the award to nothing or a token amount. This is the tenant's strongest line.\n- **Insisting on the full £340**: this contradicts the guidance on betterment and undermines the landlord's credibility on reasonableness generally.\n\n# Draft position statement for the adjudicator\n\n---\n\n**Position Statement — Deduction for damage to living room carpet**\n\n1. **The claim.** The landlord seeks a deduction from the deposit in respect of staining damage to the living room carpet caused during the tenancy.\n\n2. **Condition at check-in.** The signed check-in report, agreed by both parties, records the carpet as \"worn throughout, marked in two places near the door.\" No staining in the centre of the room was recorded.\n\n3. **Condition at check-out.** The check-out photograph (Exhibit A) shows a dark stain approximately 40cm across in the centre of the room. This did not exist at check-in and cannot be attributed to fair wear and tear: it is not reasonable deterioration through normal use, but discrete damage occurring during the tenancy.\n\n4. **Remedy sought.** The landlord accepts that the carpet was 9 years old at check-in and in worn condition, and does not seek the full replacement cost of £340 (Exhibit B, quote), recognising that a full award would place the landlord in a better position than before the tenancy. The landlord instead seeks an **apportioned sum reflecting the remaining useful life of the carpet**, and invites the adjudicator to assess that apportionment on the evidence, applying it to the quoted replacement cost of £340.\n\n5. **Burden of proof.** The landlord accepts the burden of showing the deduction is reasonable and relies on: (a) the signed check-in report; (b) the dated check-out photograph; (c) the replacement quote. [*Insert if available:* (d) the original purchase invoice for the carpet; (e) evidence that cleaning was attempted/assessed as unable to remove the stain.]\n\n6. **Conclusion.** Damage beyond fair wear and tear occurred during the tenancy. The landlord seeks a reasonable, apportioned award rather than betterment, consistent with the scheme's guidance.\n\n---\n\n**Tactical note for the agent (not for submission):** the statement deliberately concedes the betterment point up front. Claiming £340 outright would likely fail and colour the adjudicator's view; conceding apportionment and inviting the adjudicator to fix the figure maximises the credibility of the residual claim.

A one-way announcement (\"rent goes up £75 from next month, thanks\") is a demand, not an agreement. Unless and until the tenant actually agrees and that agreement is recorded in writing, this route has not been used.\n\n2. **It is not an increase under a rent review clause.** On the facts given, the agreement contains no rent review clause, so there is no clause procedure to follow.\n\n3. **It is not a valid statutory notice.** The third route is the *statutory notice procedure that applies to the type of tenancy in question*. An informal text does not follow any prescribed procedure, and the excerpt is explicit about the consequence: a notice served under the wrong procedure, or with the wrong notice period, **is not effective, and the tenant is not obliged to pay the increased rent**.\n\nSo, as things stand, the purported increase does not bind the tenant.\n\n# The three routes and which are open here\n\n| Route (as the excerpt gives it) | Open on these facts? |\n|---|---|\n| Agreement between landlord and tenant, recorded in writing | **Open** — but only if the tenant genuinely agrees, and the agreement is put in writing. He cannot manufacture this route by announcement. |\n| Rent review clause in the tenancy agreement, followed exactly | **Not open** — no such clause exists in this agreement. |\n| Statutory notice procedure applying to this type of tenancy | **Open** — the tenancy is periodic (having rolled on after the fixed term), and this is the route available where the tenant does not agree. But it only works if the correct procedure and the correct notice period for this type and stage of tenancy are followed. |\n\n# What to look for in the agreement\n\nThe excerpt says the correct route depends on the type and stage of the tenancy **and on what the agreement says**, so he should check the agreement itself before doing anything else:\n\n- **Any rent review clause** — that is, any provision setting out a mechanism or procedure for increasing the rent during the tenancy. If one does exist (contrary to what he believes), its procedure must be followed *exactly*; a departure from it will not be effective.\n- **Confirmation of the type and stage of the tenancy** — the agreement's terms will bear on what kind of tenancy it is and what it became when the fixed term ended and it rolled on periodically, which in turn determines which statutory notice procedure applies.\n\n# Confirm the procedure and notice period at source\n\nIf the tenant does not agree in writing, the only remaining route is the statutory notice procedure. He must not assume what that procedure or its notice period is. The excerpt is clear that the procedure is the one *that applies to the type of tenancy in question*, and that getting either the procedure or the notice period wrong renders the notice ineffective — leaving the tenant under no obligation to pay the increase. He should therefore verify, from the authoritative source for this type of tenancy at the time he acts, exactly which notice procedure applies, which form (if any) must be used, and what notice period is currently required — and only then serve a notice that complies with all of it.

Material Information to Obtain or Disclose Before Publication\n\nThe excerpt defines material information as what \"the average consumer needs in order to make an informed decision.\" That means:\n\n- **Tenure and remaining lease term (71 years)** — this is close to the threshold where mortgage lenders refuse to lend and extension costs rise sharply. Omitting it gives a misleading impression by omission.\n- **Service charge (£2,340/year)** — a recurring cost directly affecting affordability.

It is:\n\n- **A precise factual assertion, not puffery** — the average consumer will treat it as a statement of fact, not opinion, and may rely on it for a time-critical decision (e.g., a buyer who must complete quickly).\n- **Completely unjustifiable at the point of publication** — the seller has not confirmed their position. The excerpt is explicit that the publisher must be *able to justify* a claim; here the agent isn't merely exaggerating a known fact, they are asserting something they do not know to be true at all.\n- **Transaction-shaping** — it goes to the terms on which a consumer offers, not merely their impression of the property, making it the clearest example of information a consumer \"needs in order to make an informed decision\" being replaced with an invention.\n\n(The runner-up is \"moments from the station,\" which is demonstrably false rather than unverified — but a buyer can check a map; a buyer cannot independently check the chain.)", "decider": false, "latency_ms": 29009, "cost": 0.11112, "task_score": 9, "judges": [ { "judge": "google/gemini-3.1-pro-preview", "score": 10, "violates": false, "reasoning": "The response perfectly addresses all parts of the prompt, rewriting the listing accurately, identifying material information, and correctly pinpointing the most dangerous claim using only the provided excerpt's principles." }, { "judge": "openai/gpt-5.6-terra", "score": 5, "violates": true, "reasoning": "It correctly identifies key misleading claims and gives useful factual replacements, but violates “using only the excerpt” by adding lending, affordability and transaction assertions.

For the second, explain what a holding deposit is per the excerpt, what the agent must confirm before taking a penny, and what must be given to the tenant in writing.", "output": "# Answering Both Questions Honestly\n\n## 1. \"Will the landlord definitely renew me after twelve months if I look after it?\"\n\n**What I can't promise:** I can't guarantee a renewal, and I'd be misleading you if I did. The decision to renew is the landlord's to make, not mine, and it will be made at the time — based on circumstances neither of us can predict now. The landlord's plans might change: they could decide to sell, move back in, refurbish, or adjust the rent. No agent can honestly commit a landlord to a future decision, however well you look after the property.\n\n**What I can honestly say:** A tenant who pays on time, looks after the property and communicates well is generally in the strongest possible position when renewal is discussed — landlords typically prefer keeping a good tenant to the cost and risk of finding a new one. But that's a likelihood, not a promise.\n\n**What you could reasonably ask for instead:**\n- Ask whether the landlord's stated intention is a long-term let (I can put that question to them and pass on the answer, clearly labelled as an intention, not a commitment).\n- Ask whether a longer initial fixed term could be negotiated now, if security matters to you — that's a real, binding commitment rather than a hope.\n- Ask about a break clause structure that gives you flexibility alongside a longer term.\n- Get anything the landlord does agree to in writing before you sign.\n\n## 2. \"Can you hold it for me if I pay you £200 now?\"\n\nPossibly — but not on a handshake, and not before I've done some checking. Here's the honest position:\n\n**What a holding deposit is:** It's a payment taken to reserve a property while your application proceeds. It is one of the few payments a landlord or agent is legally allowed to take — most other payments demanded in connection with a tenancy are prohibited, and taking a prohibited payment carries a penalty and can even affect the landlord's ability to serve a no-fault possession notice. So I have every reason to get this right.\n\n**What I must confirm before taking a penny:**\n- **The current legal cap** on holding deposits — the amount is capped in legislation, and I need to check that £200 doesn't exceed the cap for this property before accepting it. I won't quote you a figure until I've verified the current one.\n- **The current list of permitted payments**, to make sure nothing else I'm asking of you is prohibited.\n- **The current repayment period**, because the deposit must be repaid to you within a set period unless a specific legal ground for retaining it applies.\n\n**What you should be given in writing:**\n- Confirmation of the amount taken and what it reserves.\n- The circumstances in which the deposit can be retained rather than returned — for example, if you provide false or misleading information in your application, or if you withdraw.\n- The timeframe within which it must otherwise be repaid to you, and how (typically returned or applied toward your first rent or tenancy deposit, by agreement).\n\n**The honest bottom line:** don't hand me cash at the door.
