Simpson Environmental Services: Air Pollution and Noise
The question
To ask the Secretary of State for Environment, Food and Rural Affairs, what recent steps she has taken with the Environment Agency to prevent excessive (a) air and (b) noise pollution from Simpson Environmental Services Ltd in Slough constituency.
Answered by Emma Hardy
The Environment Agency (EA) has undertaken a range of recent regulatory actions to ensure the Simpson Environmental Services Ltd site complies with its Environmental Permit. Five site inspections were carried out in 2025 and follow-up visits confirmed that multiple noise and dust mitigation measures had been implemented and were effective. The site was last inspected on 20 May 2026.
Monitoring in response to pollution reports, along with subjective noise monitoring, has been undertaken on several occasions. Advice and guidance on pollution mitigation were provided to the company. Noise pollution from the site was assessed as having no impact given the existing background noise levels, while dust and odour complaints were not substantiated as originating from the site during the monitoring periods.
The company continues to engage constructively with the EA. A proportionate level of regulation will continue, including further site inspections to assess environmental permit compliance and ongoing amenity monitoring where appropriate.
