How we work

Our Business

SE Controls has evolved into an international and multi-faceted organisation. From product design to façade engineering to complete system installation, we are involved in almost every stage of the building process.

Our Story

In 1981 William “Bill” Perkins started a journey that has since lasted over 35 years and continues his legacy to this day. Bill was the founding father of Loanguard Ltd. trading as SE Controls, and he initially started the business selling Ships Engine Controls and Smoke Extraction Controls, thus SE Controls was born, but Smoke Extraction Controls quickly became the primary focus of the business.

Ten years later in 1991, Bill’s son William “Will” Perkins joined the company as the 4th employee. Today, Will owns the global business which now has over 150 employees and he has been instrumental in the growth from humble beginnings to an international operation delivering an extensive number of successful projects throughout the world.

Our Solutions

Smoke Ventilation
SE Controls offers a comprehensive range of natural and powered Smoke Heat and Exhaust Ventilation systems (SHEV) suitable for any size and type of building. Our systems are designed to facilitate the safe escape of occupants in the event of a fire and to enable the fire to be fought in its early stages.

Environmental Ventilation
Environmental or Natural ventilation improves indoor environments, reduces CO2 emissions and is cost efficient. Adaptive environmental ventilation systems are less costly than traditional HVAC systems, being cheaper to install, run and maintain. Adaptive natural ventilation is leading the way for a sustainable future.

Façade Automation
Automatically opening windows uses hardware, known as actuators or rotary handles, that fit directly onto the window system which push and pull the window open and closed, instead of operating the window manually.


Remote Services
Using 4G communications technology and intelligent algorithms we can analyse the data collected from our systems placed within buildings to continually improve operating efficiencies and report back on the findings of our research to help you better understand your buildings.
