We’re proud of the way we operate
Our values are the fingerprint of our business, shaping how we operate both culturally and professionally. They’re who we are and what we stand for, helping shape our internal culture and act as guiding principles to help steer us as we move closer to bringing smarter energy for all.
Our principles define us
We are one team
When we all work together, amazing things can happen. We are all committed to open dialogue and collaboration.
We put safety and wellbeing first
We take our duty seriously to create a safe working environment. We actively seek opportunities to improve safety and wellbeing. We challenge poor behaviour and recognise excellence.
We do the right thing
We always act in an honest, fair and transparent manner. We conduct ourselves professionally and with respect for our job and responsibilities. We are not afraid to say no if we feel something is wrong.
We care
We are inclusive - we respect each other and believe everyone matters. We set high standards for our work and lead by example. We make a positive difference to our colleagues, customers and communities.
We build for the future
We look to the future as we help to achieve the net-zero challenge. We deliver to the highest standards today and welcome positive change in the future. We are open to feedback to keep improving our services and products.
Our People Promise “Everyone’s Welcome” is a clear statement of who we are and who we aspire to be. We are proud of the progress we are making and remain committed to fostering an inclusive workplace where everyone can thrive. San Johal

Wellbeing at Calisen. Putting our people first
At Calisen, we recognise that our people are our greatest asset, and their wellbeing is fundamental to our success. A thriving workforce is not only essential for individual fulfilment but also drives a more engaged, productive, and inclusive workplace.
We support mental, emotional, and physical health through open dialogue and meaningful resources. Our goal is for every colleague to feel safe, valued, and empowered across all roles and locations.
In our drive to improve staff wellbeing, we have partnered with Mental Health First Aid England and now have 34 trained Mental Health First Aiders across the business.
Annual Leave
Our annual leave starts from a minimum of 22 days, increasing with service, plus bank holidays and your birthday off.
Pension Plan
Build long-term financial security with a competitive pension plan and flexible contribution options.
Health & Wellbeing
Access company sick pay, healthcare plans and our employee assistance programme for added support.
Equity, diversity and inclusion (EDI)
We champion a workplace where everyone’s welcome. Our commitment to EDI centres on fostering a culture where typically underrepresented or minority groups feel supported, valued, and empowered to thrive. We’re proud to support four Employee Resource Groups - empowerHER, progress, embRACE, and enABLE. Each champions inclusion, representation, and support for diverse voices across our business.
Regardless of your role, we want diverse representation at every level of our business. Our strength comes from how we respect, share and connect our experiences, perspectives and ideas. EDI remains central to who we are at Calisen and how we operate as a business.
