Our History

1974

The Beginning

Beginning life in 1974 as an off-shoot and specialist provider of support services to the established Eaton-Williams Group, Sontay has evolved and grown significantly over the years. Today, Sontay is a market leading supplier of control peripherals and environmental measurement devices into the HVAC market.

Medical Electronic Products

Medical electronic products were one of our first areas of successful diversification and also proved responsible for the company's name, Sontay - a corruption of the French word for health, Sante

1986

A new home

Other electronic devices soon followed. In 1986 we moved to our present Head Office and manufacturing base in Edenbridge, and four years later we established ourselves as a leader in humidity measurement products, OEM condition monitors and sophisticated, mains power disturbance monitors.

Development of new sensors

A new generation of relative humidity sensors and the development of new, low cost temperature sensors took us more directly into the HVAC sector, where customers valued our unique combination of experience, applications expertise and prompt service.

Distribution

We responded to customer demands and HVAC opportunities by setting up a distribution business alongside our manufacturing operation. This has allowed us to bring our customers access to a bigger range of complementary, high quality products.

1994

Sontay Catalogue

The first Sontay catalogue was released. Now regarded as an “industry bible”, the Sontay catalogue has evolved year on year.

2001

The Change

A change of ownership to part of the global GE operation in 2001 enabled us to build on this reputation and make substantial investment in our specialist manufacturing facility. By joining together our ability to offer global sourcing of products was greatly enhanced, so too was the expertise of our customer service and technical support teams.

6Sigma

We were also able to implement 6sigma business process management techniques and lean manufacturing practices to benefit the Sontay operation.

2004

The Focus

In 2004 the management team at Sontay acquired the company. This has brought a fresh sense of flexibility and freedom to Sontay, allowing us to re-organise and give greater clarity to our product range for HVAC and other applications.

Manufacturing

At the same time, it has enabled Sontay to re-focus the business both internally, matching the right people to the right job, and externally, so that we can make sure we're still meeting customer requirements. We have invested significantly in product development as we continue manufacturing of Sontay's core product ranges

2010

SonNet

2010 saw the launch of SonNet, the revolutionary wireless sensing system. The system was a game changer for HVAC sensing and won Product Technical Innovation of the Year at the 2011 BCIA Awards as well as being Highly Commended at the HVR Awards. 

2014

Smart Communication devices

As the industry strides forward and the requirement for building measurement data ever growing, Sontay introduced a Smart Communication range of devices to communicate over protocols such as BACnet and Modbus.

2015

Sontay Academy

The Sontay Academy grew momentum this year with a partnership with the BCIA. This along with Sontay’s own industry courses has put the Sontay Academy at the forefront of the education of Building Controls Engineers, being recognised as a finalist at many awards. 

2019

45 years!

Sontay celebrated its 45th anniversary! A fantastic achievement and testament to the company’s reputation for quality and reliability built over these years.

2020

COVID

The most unusual year in Sontay’s history. The amazing Sontay team came together and weathered the most difficult, unusual and relentless storm to continue to supply products to often key infrastructure in supporting the immediate COVID “fight” such as in hospitals. We also found that many of our products were key to getting some sort of normality back into everyday life by monitoring things like Air Quality, Occupancy Levels and Relative Humidity for bacteria control.
