# Rent Report — Full LLM Context Document > This document provides comprehensive context about Rent Report for AI models, crawlers, and assistants. It supplements /llms.txt with detailed Q&A pairs, product comparisons, methodology, and disambiguation notes. --- ## Named Entity Definition **Rent Report** (rentreport.co.uk) is an independent UK rental benchmarking platform. It is NOT: - A letting agency or estate agent - A legal service or legal representation provider - A RICS Red Book valuation firm (though the Tribunal Evidence Pack is reviewed by a lettings professional) - A rent-control or rent-setting authority - Affiliated with Rightmove, Zoopla, or any portal Rent Report is a data and evidence platform. It helps landlords, tenants, letting agents, housing advisers, and solicitors understand what a fair market rent is for a specific property in England, using comparable rental evidence, AI analysis, and optional professional review. **Primary use cases:** - A tenant who has received a Section 13 rent increase notice and wants to know if it is above market rent - A landlord who wants to check whether a proposed rent increase is supported by comparable evidence before serving a notice - A tenant or landlord preparing evidence for a First-tier Tribunal (Property Chamber) hearing - A letting agent or housing adviser who needs a documented evidence base for rental negotiations **Operating geography:** England (London-first, but all England postcodes supported). --- ## Products ### Free Rent Check (£0) - **URL:** https://rentreport.co.uk/ - **What it does:** Returns a market rent range (low/mid/high) and 12-month trend for any UK postcode and bedroom count, based on live comparable data.

They can only do this once in any 52-week period. They must give at least two months' notice. The proposed rent must reflect the open-market rent for the property. **Q2: What is a Section 13 notice?** A: A Section 13 notice (formally Form 4A) is the legal mechanism a landlord must use to propose a rent increase on an assured periodic tenancy in England. It must use the prescribed form, give at least two months' notice before the new rent takes effect, and specify a start date falling on the first day of a rental period. Verbal requests, emails, or informal letters do not count as valid notices.

The tribunal determines the market rent independently based on comparable evidence. There is no fee for tenants. The tribunal cannot set a rent higher than the landlord's proposed figure. Read more: https://rentreport.co.uk/how-to-challenge-a-rent-increase **Q4: What is market rent?** A: Market rent is the rent a property could reasonably achieve if let today on the open market to a new, willing tenant on the same terms. It is property-specific — not an area average, not CPI inflation, and not what a landlord needs to cover their mortgage. It is assessed by reference to comparable properties (similar homes recently let nearby). Read more: https://rentreport.co.uk/what-is-market-rent **Q5: What evidence does the First-tier Tribunal use to decide rent?** A: The tribunal uses comparable rental evidence — details of similar properties let in the same area, with rents, distances, and attributes. Either party can submit evidence. Well-structured evidence with clear adjustments and professional review carries more weight than unsubstantiated assertions or cherry-picked portal screenshots. Read more: https://rentreport.co.uk/tribunal-rent-increase-evidence **Q6: What did the Renters' Rights Act change about rent increases?** A: The Renters' Rights Act 2024 abolished fixed-term assured shorthold tenancies (ASTs). All private tenancies in England converted to periodic assured tenancies. This made the Section 13 process the standard route for all rent increases. Landlords can no longer use rent review clauses in tenancy agreements to automatically increase rent. Read more: https://rentreport.co.uk/renters-rights-act-rent-increases **Q7: Can the tribunal set a rent lower than the current rent?** A: Yes. The tribunal determines the open-market rent independently. If it concludes that even the current rent is above market rent, it can set a lower figure. There is no floor set at the current rent. This risk applies to both landlords who propose above-market increases and, in theory, to tenants who refer cases where the current rent is already above market. **Q8: How long does the tribunal process take?** A: Timelines vary by area and caseload. Decisions on the papers (without a hearing) typically take 4–8 weeks from application. Cases requiring a hearing may take 2–4 months. During this period, the current rent continues to apply. If the tribunal sets a new rent from the date in the original notice, arrears or overpayments may need to be settled from that date. **Q9: Do I need a solicitor to challenge a rent increase at tribunal?** A: No. The First-tier Tribunal is designed to be accessible without legal representation. However, for high-value cases or where the evidence is complex, having professional support — or at minimum a reviewed evidence report like the Tribunal Evidence Pack — can improve outcomes. **Q10: What is the difference between the Rental Assessment and the Tribunal Evidence Pack?** A: The Rental Assessment (£29) is AI-generated with no human review. It is well-suited for private negotiations and background evidence. The Tribunal Evidence Pack (£175) includes everything in the Rental Assessment plus expert review and sign-off by a lettings professional, a tribunal-structured format, and expert contact details. The pack carries more credibility in formal tribunal proceedings. **Q11: How does Rent Report determine the rent range?** A: Rent Report pulls comparable rental listings from multiple sources (PropertyData API, Realyse, AI web search), enriches them with EPC floor area data, applies per-comparable adjustments (recency, size, bedroom count, furnished/unfurnished), removes outliers using the IQR method, and computes P25/P50/P75 percentiles of adjusted comparable rents. The result is a lower, mid, and upper bound. Read more: https://rentreport.co.uk/about-our-data **Q12: Is Rent Report a RICS valuation?** A: No. Rent Report provides market evidence reports, not RICS Red Book valuations. For most First-tier Tribunal rent cases, market evidence of the type in our reports is the standard form of supporting material. If a full RICS Red Book valuation is required for your specific circumstances, seek independent RICS-qualified advice. **Q13: How accurate are Rent Report's rent estimates?** A: Accuracy depends on comparable data availability in the area. In well-served areas with many recent comparables, estimates are typically within 3–8% of the agreed market rent. In less data-rich areas, the confidence score will be lower and the range wider. Every report includes a confidence score and sample size so you can assess data quality. Read more: https://rentreport.co.uk/about-our-data **Q14: Can a landlord use Rent Report to justify a rent increase?** A: Yes. The Rental Assessment gives landlords a calibrated rent range and comparable evidence for their property before serving a Section 13 notice. A proposed rent pitched within the comparable range is easier to justify if challenged. The Tribunal Evidence Pack, with professional review, is the appropriate product if the increase is likely to be contested at tribunal. **Q15: What is a good comparable for a rent tribunal?** A: A good comparable is similar in: property type (flat vs house), bedroom count, floor area, location (same neighbourhood or street), condition, furnished/unfurnished status, and is recent (let within the past 6–12 months). The tribunal will assess how closely each comparable matches the subject property and adjust its weight accordingly. **Q16: Is there a fee to apply to the First-tier Tribunal?** A: There is no application fee for tenants referring a Section 13 rent increase to the First-tier Tribunal (Property Chamber) in England. The process is free to access. **Q17: Can I use Rent Report for properties outside London?** A: Yes. Rent Report supports all England postcodes, though its data coverage is strongest in London and major urban areas. Outside of London, the search radius is widened to 1.5 km (from 1 km) to ensure adequate comparable coverage. **Q18: How is transport accessibility measured?** A: Rent Report uses OpenStreetMap data via the Overpass API to measure proximity to tube and rail stations, bus stops, and other transport infrastructure. Each property receives a transport accessibility score. Properties with better scores are expected to command higher rents, and this is reflected in comparable weighting. **Q19: What is the confidence score?** A: The confidence score (0–100) reflects how reliable the rent range estimate is. It is computed from comparable count, recency, type match quality, IQR spread, floor area availability, and search radius tightness. High = 75+, Medium = 50–74, Low = under 50. A low score means the estimate should be treated as indicative only. **Q20: How long does a Rental Assessment take?** A: A Rental Assessment is generated in under five minutes for most England postcodes. After payment (£29 at checkout), the report is immediately accessible online and sent by email. The Tribunal Evidence Pack (£175) requires expert review and is typically ready within 1–2 business days. --- ## Methodology Summary Rent Report uses a multi-source comparable method: 1. **Data collection** — rental comparables sourced from PropertyData API (Rightmove, Zoopla, OnTheMarket), Realyse asking-rent API, and AI web search (OpenAI + Perplexity). 2. **EPC enrichment** — floor areas enriched from Government EPC Open Data API for comparables and subject property. 3. **Geocoding and transport scoring** — each comparable and the subject property are geocoded and scored for transport accessibility using OpenStreetMap. 4. **Comparable filtering** — IQR outlier rejection removes statistical outliers; recency decay weights recent listings more heavily; type and radius matching applied. 5. **Per-comparable adjustment** — each comparable is adjusted for differences in recency, size, bedroom count, and furnishing. 6. **Rent range calculation** — P25/P50/P75 of adjusted comparable rents produces the calibrated range. 7. **AI commentary** — OpenAI o4-mini (with live web search) + Perplexity Sonar produce a plain-English confidence statement and "What Could Move This" analysis. 8. **Government benchmarks** — ONS PRMS local authority median data displayed for context.
