    Frequently Asked Questions

    Indoor air quality assurance is a planned approach to showing that a building provides healthy, comfortable air. It combines routine measurement, ventilation hygiene checks, trend review and the ability to investigate problems quickly, so you have ongoing evidence rather than a one-off snapshot.

    One-off testing only captures a snapshot. Ongoing monitoring identifies trends, seasonal variations, and gradual deterioration before occupants notice. It provides continuous compliance evidence, supports proactive maintenance planning, and demonstrates duty of care — essential for FM professionals and building operators.

    A ventilation hygiene assessment inspects and measures the cleanliness of ductwork and air-handling units against BESA TR19® Air, using visual inspection, photographs and quantitative tests such as Deposit Thickness Testing or the vacuum test. You receive a report with results by system and proportionate recommendations.

    Yes. We provide three contract tiers — Essential (annual), Standard (biannual), and Managed (quarterly) — covering IAQ assessments, ventilation checks, dust deposit monitoring and trend reporting. Essential includes a dedicated account contact; Standard adds priority reactive response and a named account manager; Managed adds an annual strategy review, FM integration and SLA alignment, and priority reactive response.

    We prioritise urgent investigations such as odour complaints, staff illness concerns or post-incident checks, and agree the visit date with you when you contact us. Out-of-hours and weekend site visits are available by arrangement.
