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. Lifestyle defence increasingly difficult without objective evidence.

Homes 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. lifestyle call

Professional indemnity engaged

£149

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. lifestyle classification

Maple's analysis engine correlates humidity, surface temperature, and dew-point data against BMI thresholds. The classification is reproducible and scientifically documented — aligned with established UK damp assessment practice and accepted in Ombudsman proceedings.

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.

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.

14-day continuous logging

Sensors record humidity, temperature, and surface temperature every minute. BMI index and dew-point calculations run automatically. No WiFi or connectivity required during collection.

Upload data, receive the Maple report

Upload sensor data to the platform. Maple generates a court-ready PDF 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 £149 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 opposing surveyor had a single moisture reading from one visit. We had 14 days of timestamped sensor data showing peak humidity consistently below the structural threshold. The judge found in our client's favour before we finished cross-examination.”
