Specialists in air quality

We provide air quality, dust and odour advice, mainly to support planning applications and environmental permits.  We want to help you get your consents as painlessly as possible, so we screen out the need for a detailed assessment if we can. If not you can rely on us for a professional air quality service from providing the initial quote to completing a detailed assessment for your application.  Our expertise means we can provide an experienced expert witness for your CPO or planning inquiry if required.

Brook Cottage Consultants also provide litigation support related to air emissions, dust or odour nuisance or exposure to poor air quality, and support for local authorities developing guidance and policies on air quality. 

We aim to provide a high quality service at a reasonable price.  To ensure we can deliver we work with a network of associates to provide the expertise you require.
