About Calibre

Calibre Climate is a family-run business specialising in the design and installation of discreet, integrated air conditioning systems for some of England’s finest homes.

With offices in Peterborough and Kings Langley, this role will be primarily based at our Peterborough office, although hybrid / remote work may be possible.

Despite our continued growth and success, we remain committed to maintaining the friendly, supportive culture that comes with being a family-run business.

This includes providing an excellent working environment with modern facilities, complimentary lunches, free on-site parking, and regular team-building and social events throughout the year.

We are looking for someone who will not only excel in their role but also contribute their own enthusiasm and positive energy to the team, helping us maintain an enjoyable and productive workplace for everyone.

As such, the successful candidate should demonstrate the potential to lead and develop a team, fostering a culture of accountability, continuous improvement, and operational excellence.
