About Us

Building on more than 25 years of experience, creating engineered solutions for applications in marine, construction, mobile climate and technical control systems, Stream Enviro is a centre of excellence for bespoke environment HVAC.

Established as an independent business back in 1999, Stream was built on a foundation of more than 10 years of hard won prior experience in HVAC engineering and associated disciplines including acoustics, electrical and electronics, physical and chemical, and human physiology.
Since those early days our philosophy has hardly changed, only to incorporate the advantages of digital and network-based control and reporting, and as a company we now bring 25 years of specialist engineering solutions experience to the challenges of the current bespoke HVAC requirement.
Based in London, with excellent access to road, rail and air communications we are ready to take on your engineering challenges. Stream is active in marine and construction HVAC, control systems and information technology.

We specialise in integration of the disciplines necessary to resolve today’s challenges. Working within structural engineering constraints, the refrigeration, thermodynamics, acoustics, electrical, controls and human physiological issues are taken into account to produce rugged and powerful systems that return efficient results over time.
We create environments which are conducive to people being able to work at peak and optimum levels. That includes personal focus, effectiveness and safety – so getting the right climate is actually about helping to get the best from people. We also embrace a number of other technology disciplines alongside advanced HVAC, such as acoustics, noise vibration and harshness (NVH), and health and usage monitoring systems (HUMS). This enables us to develop integrated and science-based solutions for extremely challenging operational requirements.
Another area of our work which is applicable to many modern applications is ‘silent’ HVAC and noise management for confined space enclosures, shelters and containers. Our project portfolio includes integrated systems for recording studios – where the air conditioning has to operate effectively, but with no noise intrusion whatsoever. We have also installed systems in listed buildings, where the equipment effectively has to be ‘covert’ to retain the character of the original structure. These and other examples show the capability to think creatively as engineers – and to evolve solutions which can be as unusual and unconventional as they are successful.

What Others Are Saying

"following a recommendation, we gave Stream the opportunity to estimate for our HVAC requirement on a new shop fit in Knightsbridge. We were very pleased with the price, speed and quality of service provided by Miles and his team at Stream Environmental. Following that successful completion we have used them on various high end residential refurbishment projects where they have continued to provide an excellent service and we would have no hesitation in recommending them to others requiring a competitive,reliable and professional AC company."

I have used Stream Enviro twice and have always found their services excellent. I will definitely be using them again as well as referring their services to my friends and colleagues. Thank you

Private customer,

We develop super prime London residential property and have worked with Stream Environmental very effectively. They have installed air conditioning systems for us and are efficient, reliable and competitive on price and we would recommend them.

James Whitmore, Truscott

We have been working with Stream Environmental for our air-conditioning needs for over 5 years and have always found them to be efficient and reliable. They have installed new units over 3 of our sites and have maintained the service contracts in our other locations. I would highly recommend them as they deliver a personalised service at good value for money.

April Lavers, MDHeming

Stream Environmental have worked with us for nearly fifteen years. We rely on them to maintain the air-conditioning units in our critical server room and to provide practical advice and technical support for projects including our office move in 2012, which involved installing a new system on a very tight timetable. We have found them responsive, personable, effective and competitive and we would happily recommend them.
