For surveyors
Your professional opinion. Backed by 14 days of data.
A single site visit creates a snapshot. Damp and mould is seasonal, behavioural, and time-dependent — patterns that only continuous sensor data can capture. Maple Diagnostics gives surveyors the objective evidence to make findings that hold up in court, in Housing Ombudsman proceedings (social housing), and against opposing experts. Where Awaab's Law applies — registered providers from October 2025 — continuous data directly supports the investigation record required within 10 working days.
Awaab's Law
Applies to social housing only (registered providers). In force from October 2025. Strict investigation and written-findings deadlines. Private sector extension pending — no confirmed date.
Section 11 LTA 1985
Applies to all landlords with tenancies under 7 years. Covers structure, exterior, and installations. Condensation defence increasingly difficult without objective evidence.
Homes Act 2018 & HHSRS
Homes (Fitness for Human Habitation) Act 2018 & HHSRS applies to all landlords. Property must be fit for habitation. HHSRS hazard scoring used by councils for enforcement. Sensor data is admissible in appeal proceedings.
The problem with snapshots
One visit. One moment in time.
Findings rejected
Survey methodology challenged — single visit
No data to support your opinion
Expert undermined
Opposing expert submits sensor evidence
Your report becomes the weaker submission
Liability exposure
Client disputes your structural vs. condensationcall
Professional indemnity engaged
£249
Maple 14-day kit per survey
Objective data. Defensible findings.
What Maple adds to your survey
Four ways it strengthens your methodology.
14 days, not 14 minutes
A site visit captures a snapshot. Damp is seasonal and behavioural — it manifests differently in winter, on heating days, when laundry is drying. Continuous sensors capture what a single inspection cannot.
Automated structural vs. condensation classification
The classification is reproducible and scientifically documented — aligned with established UK damp assessment practice. Consistent with the evidential standards referenced in Housing Ombudsman maladministration findings.
Your opinion, defended
A Maple report doesn't replace your professional judgement — it backs it. Timestamped data that answers every question a solicitor or Ombudsman will ask. Professional indemnity is better protected with evidence on file.
A differentiator for your practice
Surveyors who include continuous sensor data in their methodology win more instructed cases, charge higher fees, and produce reports that solicitors and insurers actually trust. It's a commercial upgrade, not just a tool.
How it works
Three steps. No disruption to your workflow.
01
Deploy sensors at the property
Place calibrated sensors in affected rooms during or after your site visit. No installation required — plug in and position. The tenant can manage this themselves.
02
14-day continuous logging
Sensors record humidity, temperature, and surface temperature every minute. Building Moisture Index and all the calculations run automatically. No WiFi required during collection.
03
Upload data, receive the Maple report
Upload sensor data to the platform. Maple generates a evidence-grade reporting classifying cause, with full timestamped evidence trail. Attach it to your survey report or use it as a standalone evidential document.
Common concerns
What surveyors ask first.
"My visual inspection and moisture readings are already sufficient."
They may be — for a straightforward case. But in disputed cases, opposing experts increasingly use continuous sensor data. A 14-day dataset makes your methodology the stronger submission. Courts give greater weight to continuous monitoring evidence; the Housing Ombudsman expects landlords to use competent surveyors and keep proper records — sensor data directly supports both.
"Adding sensors makes the survey process slower."
Sensors are deployed at the end of your site visit and collected 14 days later — your client handles collection. Your time investment is 10 minutes of placement, not 14 days of attendance.
"The client won't pay for the additional cost."
At £249 per property, it's line-itemable. Most instructing solicitors and landlords will pay for a report that defends their position — because their legal fees dwarf the kit cost. Frame it as evidence enhancement, not an extra charge.
The deliverable
What the Maple report contains.
Timestamped sensor data
Full 14-day log of humidity, temperature, and surface temperature readings. Every data point dated and signed.
Building Moisture Index and dew-point analysis
Maple's Building Moisture Index methodology — developed with the UK Property Care Association — applied alongside dew-point calculations established in UK building science.
Structural vs. condensation classification
A clear, scientifically documented determination of probable cause with threshold evidence. Reproducible and defensible.
Evidence-grade PDF reporting
Formatted for use in disrepair proceedings, Pre-Action Protocol exchanges, Ombudsman submissions, and expert witness bundles.
