Air Quality & Odour

Cass Allen provides specialist air quality and odour consultancy services to support development, construction and infrastructure projects throughout the UK.

We work with developers, planning consultants, architects and other project professionals to identify and assess potential air quality constraints, support planning applications and develop practical mitigation strategies.

Our experienced team provides technical advice throughout the development process, from initial feasibility and site suitability assessments through to planning, construction and occupation.

We also investigate existing indoor air quality concerns, helping clients identify potential sources of pollution, assess their impacts and develop appropriate solutions to improve indoor environments.

Assessments for Planning and Due Diligence

At both due diligence and planning stages, our task is to demonstrate the suitability of the site for development, both in terms of the exposure of future occupants, and potential impacts on local air quality.

Odour Assessment

We use a range of qualitative and quantitative assessment tools to achieve our clients’ goals.

Construction Phase Assessment

Assessment of construction phase dust and particulate matter emissions is generally required demolition or construction activities will take place within 350m of other sensitive uses.

Emissions Mitigation Strategy

With a growing push to achieve air quality neutral, or even air quality positive status, we can help to incorporate mitigation into development design.

Indoor Air Quality

There is an increasing emphasis from policy makers on indoor air quality, and the influence this has on people’s health, wellbeing and productivity.

Air Quality Monitoring

We provide a range of air quality monitoring services for specific client needs, including short and long-term, personal and static, pumped and passive sampling of gases, particles and odour in both indoor and outdoor environments.
