Who are we?

Welcome to Ecotest! We’re a family led company that’s been helping clients improve their environment inside and out since 2007.

Our journey started with air tightness testing, developing extensive experience in both domestic and commercial applications, and we’ve since grown to become specialists in bespoke end-to-end ventilation solutions.

At the heart of our business is our commitment to making a positive impact on the environment. When Steve Talbot founded Ecotest, he saw an opportunity to develop a business that supported growing concerns for the environment and would help buildings become more sustainable.

With the addition of Director, Alex Tonge, we’ve expanded our services to include comprehensive ventilation solutions. And we’re not stopping there! We’re constantly looking for ways to grow and improve, driven by our passion for improving your environment inside and out.

Our mission, vision, and values

Our mission is to improve the environment inside buildings and the impact of those buildings on the wider environment.

Our vision is to establish Ecotest as the leading company for air tightness and ventilation solutions, for self-builds and environmentally conscious developments.

Our values are:


We believe in the importance of environmental responsibility and strive to make a positive impact through our work.


We are committed to delivering the highest quality products and services, backed by our experience and a dedication to continuous improvement.


We are trustworthy and dependable, delivering on our commitments.

Our management team

Alexander Tonge


Alex obtained a First Class Honours in History before joining a FTSE 100 company as a graduate, where he gained 7 years experience in both procurement and project management. Notably he achieved MCIPS status in Procurement and was awarded ‘Up and Coming Professional of the Year’ in 2018.

Despite his success within the organisation, Alex did not feel fulfilled and wanted a career that improved the quality of people’s lives and the environment. So in 2021 he took the bold decision to take a leap of faith, leaving his employment in what many would see as an aspirational career. This previous experience provides valuable business insight to Ecotest.

Alex is fully accredited with both the Elmhurst Air Tightness Scheme and Ventilation Scheme and is continually looking to expand his professional development.

Within Ecotest Alex shares the leadership responsibilities with Steve Talbot and leads the business development activities alongside the ventilation arm of the business.

Outside of work Alex is a recent father and a self-confessed golf addict. When he’s not with his family, the golf course is often where you will find him.

Steve Talbot


Steve completed an Honours degree in Electronic Engineering in the early 1990s and following this had a career in telecoms software development. After redundancies swept the telecoms industry, Steve took the opportunity to found Ecotest in 2007, providing air tightness testing services throughout the North of England, Southern Scotland and Northern Wales.

Back then air tightness testing was a relatively new discipline and had only just been brought into the UK Building Regulations. Steve was part of a small collaboration of air tightness testers that took the initiative to establish the Independent Air Tightness Testing Scheme (iATS) gaining UK government approval as a competent person scheme.

iATS subsequently moved under the ownership of Elmhurst to become the Elmhurst Airtightness Scheme (EAS) of which Steve is a certified member.

Within Ecotest Steve shares the leadership responsibilities with Alex Tonge and leads the business operations alongside the air tightness services arm of the business.

Away from Ecotest, Steve is keen on all sports and has held a season ticket for his local football team since 1982! He loves spending time with his family and in particular his grand daughter.
