Sontay’s mission is to create healthier and more energy efficient buildings that support businesses, help people and protect the planet. We provide solutions that improve the indoor environment, reduce energy consumption and put sustainability at the heart of innovation.

What we do…

Sontay is the leading independent manufacturer of Building Management System (BMS) peripherals in the UK with a rapidly growing presence around the globe. 

Our Sensors support the creation of comfortable, energy efficient & healthy buildings

We work with system integrators, OEM’s, Facilities Managers and end users to deliver sensors that support the creation of comfortable, energy efficient & healthy buildings.  We have a proven track record and reputation for innovation, integrity and quality.

Ever wondered how indoor environments are controlled?
When you are staying in a hotel or at the shopping centre, there is an intelligent building management system measuring and controlling things like temperature, humidity and CO2 levels.  This maintains occupancy comfort levels and also conserves energy by monitoring occupancy and light levels and switching off heating or air conditioning when optimum levels are met.

Sontay design and manufacture the sensing devices that feed the data to the building management systems to create a Smart Building. With our strong ethics in customer service, we are renowned in the industry for excellence in this field.

If our customers need to measure something related to HVAC, we can help.

We deliver sensors that measure RH, temperature, CO2, pressure, air quality… the list goes on. Our products are compatible with most building management systems and use industry standard values or protocols.  Whether our customers are working on a brand-new project or looking at a replacement, we are there for them every step of the way.
