Air Quality Testing — South East England
Independent air quality and ventilation assessors · Based in Bexley, Kent
Green Air Monitoring delivers regional indoor-air and ventilation programmes for facilities providers, managing agents and organisations operating commercial property across South East England. A common method and report format lets central teams compare sites, while local scopes preserve differences in building type, occupation and outdoor context. We cover London, Kent, Surrey, Essex, Sussex, Hertfordshire, Berkshire and the wider South East.

Buildings and districts we cover
The wider region includes Berkshire centres such as Reading, Slough, Bracknell and Maidenhead, plus Sussex locations including Crawley and the Gatwick area, Brighton and Horsham. These sit alongside our detailed London, Kent, Surrey, Essex and Hertfordshire coverage. Thames Valley technology and corporate campuses often contain several buildings under one management structure. Gatwick Diamond business parks mix offices, logistics and airport-related activity, while coastal hospitality combines guest accommodation, event space and commercial kitchens.
- Thames Valley corporate and technology campuses across Reading, Slough and Bracknell
- Gatwick and Crawley business parks with aviation, hotel and logistics influences
- Brighton and Sussex hospitality, education and commercial properties
- Managed portfolios extending across London and several home counties
- Mixed programmes combining occupied IAQ, ventilation hygiene and targeted investigations
Local factors that affect indoor air and ventilation
A regional programme must account for very different outdoor and operational settings. Motorway and airport corridors influence some intakes; coastal locations have another background; town-centre refurbishments may sit beside active construction. Building stock ranges from sealed headquarters to converted premises and hotels with substantial kitchen extract. Consistency comes from agreed instruments, sampling logic, terminology and report structure, not from forcing every property into identical test locations. Exceptions and access limits are recorded so central comparisons remain honest.
- Traffic and aviation influences near the M4, M25 and Gatwick corridors
- Fit-out and construction activity around growth and regeneration areas
- Coastal hospitality with seasonal occupancy and intensive kitchen operation
- Corporate campuses with multiple AHUs, tenancies and operating schedules
- Long-distance portfolio planning that must protect calibration and sampling consistency

Governing a regional monitoring programme
The most useful regional programme begins with governance rather than a list of instruments. We agree which assets are in scope, the decisions made centrally and locally, how exceptions are approved and how follow-up is tracked. A core survey can define common indoor and outdoor parameters, equipment checks, location naming and report headings. Site modules then add TR19 inspection, kitchen extract, compliance testing or reactive work only where justified. This keeps a Reading headquarters, a Gatwick hotel and a Kent logistics office comparable on shared questions while respecting the specific systems and exposures of each property. Survey rounds are sequenced around occupancy, project dates and geography, with calibration and data handling kept consistent. Portfolio summaries show recurring findings and priorities, while each property retains its own limitations and evidence trail. The approach supports procurement and FM review because it separates independent assessment from cleaning, maintenance and remedial delivery, and it allows later verification to repeat the relevant baseline method.
- Define portfolio decisions, owners and exception rules before scheduling visits
- Use a controlled core method with site-specific modules for genuine local risks
- Keep property evidence available beneath regional summaries and trend reporting

How we work in South East England
Regional instructions begin with the portfolio map, risk priorities and reporting users. From Bexley we group visits sensibly across Berkshire, Sussex and adjoining counties, without compressing site work simply to reduce travel. Local contacts confirm access, parking, inductions and plant support. Out-of-hours visits can be arranged property by property. We agree travel, access and the visit date with you for each survey.
Enquiry
Provide the South East asset list, building uses, priorities and the decisions required at site and portfolio level.
Scope
We create a core method, identify justified variations and agree how results will be named and compared.
Visit
Survey rounds are planned from DA5 by geography and operating need, with out-of-hours access arranged individually.
Report
Each site has its own evidence, limitations and actions within a consistent regional reporting framework.
Follow-up
We review trends with the central team and refine future rounds as assets, occupancy or risks change.
Limitations
We agree the scope for each South East England property before attendance so that the report provides a precise answer to the commissioning question based on measured evidence.
- Regional consistency does not make unlike building types directly equivalent.
- Travel and access are agreed for each survey round; we coordinate timing based on your specific site requirements, ensuring our visit fits the needs of each property.
- We provide dedicated expertise across London and the South East.
