Service Contracts

ET’s team of highly skilled service engineers is the largest in the country.

Engineers are strategically located around the UK and Ireland to guarantee that CEM and Air Quality Monitoring Station emergencies are responded to within as little as 48 hours (depending on the agreed service level), keeping data capture rates at the high levels expected by Government, Local Authorities and Environmental Regulators and more than 200 valued customers.

Our service agreements can be entirely bespoke and can include: 

  • All travel, mileage, subsistence and labour charges. 
  • Consumables (eg filters). 
  • ET's Technical Support Engineer (TSE) Telephone Helpline. 
  • Servicing backed by ISO 9001:2015 quality procedures.
  • Software support 
  • Service and emergency breakdown callout for air conditioning equipment. 
  • Replacement gas cylinders and rental charges. 
  • Other client bespoke requirements.

Please call Becky Mitchell to discuss the level of service which is best for you.

"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".

Ana Beckett
Senior Air Quality Analyst ERG, Kings College London


"Falkirk Council have found ET offer an excellent level of support for the stations covered under contract. For example ET have attended sites within the 48 hour call out period when analysers have failed and have also offered remote technical support to Local Site Operators when required. Overall the council is very satisfied with the level of service we have received from ET, particularly in regard to quick response times for analyser failures as this assists us in achieving high data capture across our automatic air quality monitoring network."

Kind Regards,
Tanith Allinson, Falkirk Council
