Making Vital Connections

We’re the bright British innovators of award winning cloud communications software – connecting people to organisations when it’s critical they get through. For 15 years we’ve specialised in untangling communication systems and putting them into the cloud for organisations that provide a vital service in healthcare, travel, the voluntary sector and customer services.


We help primary and urgent care providers tackle growing pressures, by matching clinical capacity with patient demand – anytime of the day or night.

The Sesui Difference

We’re problem solvers, we look at every angle. The things you hadn’t considered, or didn’t even know were possible. It means we can truly make a difference, with solutions that help not-for-profit organisations achieve more with finite resources, and commercial organisations to stand out from the competition. We call this the Sesui difference — it’s nimble, elastic and sustainable.

Clients, Partners & Accreditations

With telephone donations increasing year-on-year, it was important our contact centre solution could adapt and grow alongside the St Martin-in-the-Fields Christmas Appeal. Sesui provides us with a high level of insight from the call data, and the team works with us to refine the process for next time.

“Our customers don’t care where the team is based. All they want to know is that we’re committed to supporting all of our European territories. And thanks to the Sesui Virtual Contact Centre, we’re able to give our customers the service they expect, in their own language.”

You can rest assured that we have: secure connections, devices and software; controlled access to our data; up-to-date devices; and full protection against viruses and other malware. All fully certified as part of the government’s Cyber Essentials scheme.

Cyber Essentials

Eight years ago Sesui became one of the stakeholders in our vision for the future, and we made the decision to put our phone system in the cloud. Back then the cloud was a Silicon Valley buzzword and not particularly ‘NHS’. But we did it and very quickly saw results.

When an OHES Environmental customer needs to contact us, it’s critical that they get through. Sesui supplies a level of reliability that means customers can call us and we can immediately meet their needs.

We’re one of just a handful of approved communications providers on Practice Index, set up to help practice managers find the very best partners for their organisation.
