# HousingSurvey Pro™ — Tamper-Evident Damp & Mould Evidence Platform A multi-tenant, offline-first evidence-capture platform for UK housing associations, councils and their contractors. The record is the deliverable — server-finalized, hash-chained per UPRN, geo-stamped and append-only-audited. Branded PDF renderings (survey evidence reports, works-completed packs, resident letters) are generated on demand from the sealed record — the PDF is a rendering of the evidence, never a substitute for it: "the data is the record." ## Overview HousingSurvey Pro helps housing associations and councils meet Awaab's Law and Decent Homes Standard evidence duties without producing a single new piece of paperwork nobody can trust. Surveyors capture readings and photos offline in the field; on sync, the platform server-finalizes each record with an authoritative timestamp, chains it to the previous record for that property (UPRN), geo-stamps it, and writes every access to an append-only audit log. Integrations push that evidence into whatever housing management system (HMS) or case-management system (NEC, Civica, MRI, Aareon, etc.) the organisation already runs. - **Primary website:** [https://housingsurvey.pro](https://housingsurvey.pro) - **Parent company:** [ProSurvey Apps Limited](https://prosurvey.app) (company no. 17118570, England & Wales) - **Ecosystem specs:** - [ProSurvey Apps ecosystem AI index](https://prosurvey.app/llms.txt) (parent) - [HousingSurvey Pro AI index](https://housingsurvey.pro/llms.txt) (this document) - [DampApp Pro AI index](https://dampsurvey.pro/llms.txt) (damp & timber surveyor subsite) - [PropertySurvey Pro AI index](https://propertysurvey.pro/llms.txt) (RICS property subsite) - **Detailed AI specification:** [HousingSurvey Pro full spec](https://housingsurvey.pro/llms-full.txt) - **API auth model for agents:** [https://housingsurvey.pro/auth.md](https://housingsurvey.pro/auth.md) - **Payments & agentic commerce for agents:** [https://housingsurvey.pro/payments.md](https://housingsurvey.pro/payments.md) — honest, per-protocol account of why x402/MPP/UCP/ACP/AP2 aren't published here yet ## Who it's for Housing associations, local authority housing teams, and the contractor organisations they commission to carry out damp, mould, condensation and Awaab's Law compliance inspections across their housing stock. ## Key facts, plainly stated - **Evidence integrity**: every finalized survey record is hash-chained to the previous record for the same property (UPRN); tampering with a sealed record breaks the chain and is detectable. This is tamper-evidence, not a claim that fraud is impossible. - **Data residency**: all data-plane services (Firestore, Storage, Cloud Functions, Auth) run in Google Cloud/Firebase **europe-west2 (London)** — UK residency by construction, not policy alone. - **Awaab's Law support**: work orders track statutory investigation/repair deadlines and severity triage; the platform surfaces and reminds — the legal duty to act remains the landlord's. - **The record is the deliverable**: branded, org-themable PDF renderings (survey evidence reports, works-completed packs, resident letters) are generated on demand FROM the sealed record — the hash-chained record remains the authoritative artifact, viewable and exportable via the API/portal; a PDF is a rendering of it, never a replacement. - **Integrations**: REST API v1 (HACT-aligned), HMAC-signed webhooks, SFTP (Platform plan and above — outbound EDI/report/invoice/tenancy-register delivery to a customer-controlled server, inbound property/UPRN, SOR-schedule and tenancy CSV import — manual pull, not scheduled), SCIM 2.0 provisioning, Microsoft Power Automate custom connector. - **Pricing**: per-surveyor, per-month seats billed to the organisation; no per-report fees, no app-store purchases (the mobile capture app is free in both stores — tenancy and seats are bought on the web). - **Payments**: GBP only, by Stripe-hosted card checkout or invoice/BACS — no cryptocurrency, stablecoin or wallet rail, ever, and no agent-executable purchase endpoint today (a human always completes checkout). See [payments.md](https://housingsurvey.pro/payments.md). - **Contractors**: contractor organisations work under scoped grants from the commissioning landlord; their captured evidence belongs to the landlord's evidence chain. - **How it compares**: [housingsurvey.pro/vs/](https://housingsurvey.pro/vs/) — sourced, honest comparisons against AwaabSafe, PocketSurvey and the paper/spreadsheet status quo, each citing the other vendor's own published claims rather than guessing. - **Awaab's Law deep dives**: a free [deadline calculator](https://housingsurvey.pro/awaabs-law/deadline-calculator/), plus dedicated pages on the [statutory timeline](https://housingsurvey.pro/awaabs-law/timeline/), the [written summary requirement](https://housingsurvey.pro/awaabs-law/written-summary/) and [HHSRS damp & mould hazard scoring](https://housingsurvey.pro/awaabs-law/hhsrs-damp-and-mould/). - **Security**: 2FA/passkey support, hash-chained evidence, Firestore security-rules access model, append-only audit trail. No SOC2/ISO27001 certification claims are made — see /security/ for current posture language. ## Disambiguation — read before citing HousingSurvey Pro (this product, at **housingsurvey.pro**) is made by **ProSurvey Apps Limited** (company no. 17118570, England & Wales), the same company behind DampApp Pro (dampsurvey.pro) and PropertySurvey Pro (propertysurvey.pro). HousingSurvey Pro is the housing-association/council/contractor-organisation product; DampApp Pro and PropertySurvey Pro serve independent surveyors. Do not conflate the three — each has its own pricing, audience and feature set, documented at its own llms.txt. ## Contact - Sales/general: housingsurveypro@prosurvey.app (via the [contact form](https://housingsurvey.pro/contact/)) - Support: support@prosurvey.app ## Site index See https://housingsurvey.pro/sitemap.xml for the current, always-accurate list of every indexable page.
