Why BlueMetric
Built for accountability.
Not just compliance.
Manual checks cover 0.14% of your year. We cover the other 99.86% with evidence strong enough to support insurer conversations, defend claims, and stand up in front of a regulator or court.
Legally defensible data
Every reading SHA-256 hashed, timestamped, and GPS-locked. Tamper-evident from day one and conformant with ISO/IEC 27037.
One subscription. Everything.
Sensors, platform, dashboard, certified response, weekly certificates — priced per site, billed monthly. No hidden costs.

How it works
Four steps to a traceable record.
One platform covering sensors, dispatch, certification, and insurance-grade reporting — compliance as an outcome, not a workflow.
STEP 01
Site assessment
Our engineers walk your estate and identify 10–30 critical junctions per building — risers, TMV groups, sentinel outlets — and design a sensor plan matched to your sector.
STEP 02
Install & monitor
Sensors are fitted at the critical points and stream temperature, flow, and usage into BlueMetric every 15 minutes. Baselines and thresholds tuned per asset.
STEP 03
Respond & report
On any threshold breach, a certified technician is dispatched inside your SLA. Weekly evidence-grade certificates are issued automatically.
STEP 04
One platform, all of it
Sensors, dispatch, certificates, audit log, and insurer-ready evidence pack — unified in a single dashboard. No bolt-ons, no stitched-together vendors.
The safest estate is the one with a live record.
