"I am really happy with the service ET provide, the response time is brilliant and the advice given always professional and apt."

Dr Jolanta Obszynska, Leicester City Council

"Enviro Technology consistently exceeds service targets surrounding its air quality monitoring equipment in London. Call outs for sites under five day contracts are typically responded to within two to three days. And those with 48-hour contracts see a response time of between 25 and 40 hours".
