* Working with the Change of Tenancy team to ensure smooth transitions


Reporting & Recharges


* Preparing accurate client reports ahead of schedule
* Pulling together data for tenant recharges and ensuring everything aligns with agreed methodologies


You’ll also occasionally travel to UK sites for meetings — a great chance to build relationships and see the impact of your work first‑hand.

Desirable


* Experience using platforms like Optima, Asana, Zendesk or similar
* A natural curiosity and a drive to improve processes
* Someone who enjoys problem‑solving and isn’t afraid to ask questions


💬 Why This Role Matters


You’ll be joining a large, friendly team that’s passionate about delivering a high‑quality energy and utilities service. Your work underpins everything the Client Managers deliver — and you’ll be supported with ongoing training, development and opportunities to grow.
