Water and air compliance for commercial estates.

Multi-site Legionella compliance, water hygiene monitoring, closed-system optimisation and air hygiene for offices, hotels, retail, high-rise residential and managed property — built for FM teams who need one record across many buildings.

Sector challenges

Why commercial is different.

Every sector has its own compliance edge cases — the bits that catch out a generalist water treatment provider. Here are the four we design our commercial programmes around.

Multi-site portfolios

FM teams managing 10–100 buildings need consistent compliance across the lot — same engineers, same data, one defensible record.

Hotels & high-occupancy

Hotel water systems run hot, hard and constantly — Legionella risk is higher than a typical office and TMV cycles are tighter.

Closed-system optimisation

Chiller and AHU performance lives or dies on closed-system chemistry — BG50 sampling pays for itself in pump life and chiller approach.

Insurer-friendly evidence

Commercial insurance increasingly asks for evidence of compliance at renewal — we produce it in the format insurers ask for.

Frequently asked

Answered by engineers.

Can you manage 50+ sites under one contract?
Yes — that's the work we do best. One contract, one portal, one senior engineer accountable across the portfolio, monthly executive dashboard, exception alerts straight to the FM team.
Do you work as a subcontractor for our total FM provider?
Yes. We white-label delivery for major FM providers — working within their CAFM, branded reporting and KPIs. The client sees the FM badge; the FM gets a specialist behind it.
Can you integrate with our CAFM system?
Yes — we routinely integrate with Concept, Maximo, Verisae, FAMIS, Planon and others. Visit data, asset records and certificates feed straight into your asset management system.
What about high-rise residential blocks?
Same compliance regime as commercial office — Legionella risk assessment, monthly temperatures, calorifier inspection, TMV servicing. We work with managing agents and building owners directly, with leaseholder-friendly visit notification.
