Remote Temperature Monitoring

Your water safety, live.

Monitored every 30 seconds — not once a month.

Continuous remote temperature monitoring for hot and cold water systems, exceeding HSG274 Part 2 and ACoP L8, with instant out-of-spec alerts and an audit-ready record for every outlet, across every site.

The monitoring gap

Manual checks only show the temperature the moment someone was standing there.

A monthly or weekly check is a single snapshot. Between visits, an outlet can drift out of the safe range for days, and a paper log will never show it. The risk isn't the reading you took. It's the hundreds of hours you didn't.

Remote Temperature Monitoring

As the dutyholder, that gap is yours.

Under ACoP L8 you're responsible for keeping your water systems safe, and for proving it. Missed out-of-spec windows mean Legionella growth risk, scald risk, and a record with holes in it when the HSE or your auditor asks. Continuous data closes the gap before it becomes a finding.

Manual vs Remote

Most providers hand you a checklist. We hand you evidence.

The same compliance obligation, two very different levels of certainty. Here's how continuous monitoring compares to periodic manual checks.

Remote Monitoring Manual Checks
Coverage Continuous, 24/7 Periodic snapshots
Detection Alert within hours At next visit, if at all
Records Auto-logged, audit-ready Paper / spreadsheets, gaps
Site visits Far fewer Every outlet, every cycle
Human error Removed Always present
Cost & carbon Lower travel & labour High travel & labour 
How it works

Live in three steps, with minimal disruption to your building.

  • Free site survey

    We map your system and outlets, then design a monitoring scheme around your risk assessment. No obligation, no cost.

  • Wireless sensors, fitted fast

    Discreet probes retrofit to your existing pipework, no rip-out, no disruption to occupants or daily operations.

  • Watch it live

    Readings stream to your secure portal and iOS/Android app, with instant out-of-spec alerts and weekly + monthly compliance reporting.

Benefits of remote monitoring

Everything you need to prove compliance,
continuously and defensibly.

  • Instant out-of-spec alerts

    The moment a reading drifts outside safe parameters, your nominated contact is alerted — so corrective action happens in hours, not at the next scheduled visit.

  • 24/7 continuous monitoring

    Live visibility across all assets and outlets, day and night — including vacant or hard-to-access buildings, with no reliance on someone being on site.

  • Scald-risk management built in

    The same sensors that guard against Legionella also flag dangerously high outlet temperatures — protecting occupants on both fronts.

  • Audit-ready records

    Every reading auto-logged in one portal, with document upload & storage — a single source of truth.

  • Reduced cost & carbon

    Fewer site visits mean lower travel, labour and emissions across your estate.

  • Continuous compliance

    Supports and exceeds HSG274 Part 2 — built around your scheme of control.

Proof you can defend

Evidence an auditor can trust.

Compliance only counts if it holds up under scrutiny. Every Flowsafe sensor is calibrated to industry standard and confirmed by validation visits — so the data you put in front of the HSE is accurate, traceable, and complete.

The validation guarantee

Every sensor independently validated for accuracy — or we re-calibrate, free. Certainty you can stake your compliance on.

Why it matters

Compliance isn't doing the checks. It's proving you did them — correctly. Continuous data protects occupants, your reputation, and your budget. Remote monitoring doesn't just replace manual checking. It changes how defensibly you manage Legionella risk.

Common questions

Everything you might be wondering.

  • In many cases, yes — your Legionella risk assessment guides the exact scope. Remote monitoring provides continuous, accurate data that is often more reliable than periodic manual checks, and we'll help you confirm what's right for each site.

  • No. Discreet wireless probes retrofit to your existing pipework with minimal disruption to occupants or daily operations — there's no rip-out and no need for repeated access to outlets.

  • Sensors run on long-life batteries and are designed to keep working for years once installed, with no routine battery changes. Exact battery life depends on the sensor and reporting frequency for your scheme.

  • Readings are transmitted to a secure cloud portal with role-based access, so each user only sees what they should. All historic data is retained for audit and traceability.

  • Yes. One portal gives you a clear overview of task status across all premises, with weekly and monthly compliance reporting, task reassignment between users, and instant alerts whenever an asset operates outside set parameters.
