Air quality

The air quality in our borough is generally good. We carry out regular reviews to check current levels of pollutants and review predicted future levels against the government's health-based standards. 

Air quality is monitored by taking readings on how much nitrogen dioxide (NO2) is in the air. To do this we have nitrogen dioxide diffusion tubes located throughout the borough which are changed on a monthly basis. 

Every year, a report on whether the air quality within the Woking area meets the national air quality standards. This is submitted to the Department for Agriculture, Food and Rural Affairs (DEFRA) for their approval.

Air quality assessments

Areas not expected to meet the government's standards are declared Air Quality Management Areas (AQMAs). Once an AQMA has been declared, we have to produce a plan to outline what steps we could take to get pollution down to within the government standard.

We currently have two AQMA's within Woking borough. The first one covers the junction at the top of Anchor Hill. This was first declared in 2014. Since then, the pollution has been reducing. The second AQMA is for a section of Guildford Road, which was declared in 2017.

More information on where AQMA’s have been declared in Surrey and the country at large can be obtained from DEFRA.


We are a member of a scheme called airAlert. This service warns local residents who have respiratory problems, such as asthma, COPD or emphysema, when air pollution in Woking is going to be high. This is a free subscription service. 

By registering to receive alerts, you will receive either an email, text message or voicemail giving an advanced warning of high pollution levels.
