Air Quality Service Agreements for Commercial Buildings
Independent indoor air quality assessors · Since 1999
An air quality service agreement gives a building owner, landlord or occupier a defined annual programme instead of commissioning each survey separately. The scope, visit pattern, reporting and fixed annual price are agreed for the property, with a named contact who understands its systems and history. Agreements are designed for direct clients responsible for one building or a closely managed estate and can include planned indoor air quality checks, trend review and reactive technical support.

Three levels of planned support
The level is selected from the building’s use, existing evidence, ventilation arrangements and the assurance required. Scope is confirmed before pricing, so the annual figure reflects the agreed work rather than an undefined allowance.
| Level | Best suited to | Included programme |
|---|---|---|
| Essential | Annual baseline assurance for buildings requiring periodic verification. | Annual IAQ assessment; Ventilation performance check; Summary compliance report; Dedicated account contact |
| Standard | Biannual verification with dust monitoring and trend analysis. | Biannual IAQ assessments; Ventilation + dust deposit checks; Year-on-year trend reporting; Priority reactive response; Named account manager |
| Managed | Quarterly assurance programme for FM teams and multi-site portfolios. | Quarterly IAQ verification; Full ventilation system review; Dust deposit monitoring; Continuous trend analysis; Annual strategy review; FM integration & SLA alignment; Priority reactive response |

What the annual agreement includes
Every level starts with an agreed site record covering occupied zones, normal operating periods, access contacts and known issues. Planned assessments use defined locations and methods so later results can be compared responsibly. The agreement states which parameters are logged in real time, when laboratory sampling is included and how long instruments remain in place. A fixed annual price covers the listed visits and reports; optional work outside that schedule is quoted before instruction.

Selecting measurements and survey periods
Core office reviews commonly log CO₂, particulates, TVOC, temperature and relative humidity at representative occupied locations. Real-time logging shows changes with room use, time and ventilation operation. A laboratory method is added when a particular compound, such as formaldehyde or a speciated VOC, must be identified or quantified. Locations and deployment periods are chosen around the building’s questions; a short occupied check and a longer trend study answer different needs. The annual schedule can account for heating season, summer conditions or known occupancy peaks.
Reactive support between planned visits
If an odour, dust concern or comfort complaint arises, the named contact reviews the available description, affected areas and current programme data. We advise whether existing evidence is enough for an operational check or whether a targeted investigation is warranted. The investigation scope and attendance date are agreed with you. Findings are added to the building record, allowing the next planned review to check whether the action changed the measured pattern.
Renewal and annual reporting
Before renewal we summarise completed work, recurring patterns, open actions and any changes in occupation, fit-out or ventilation operation. The next programme can retain stable reference locations while changing frequency or parameters where the evidence supports it. This prevents routine testing from becoming repetitive and keeps expenditure directed towards the building’s current risks. The renewal also confirms the fixed annual price and any separately priced options.
Limitations and what this assessment cannot tell you
- The fixed annual price applies to the documented scope and named properties
- Survey findings reflect the monitoring periods and accessible locations
- Real-time TVOC screening does not identify individual compounds
- Reactive investigations outside the included allowance are agreed before work begins
