About Sero

Sero was founded to make a connection between homes and energy, and to use technology to make both of these easier and smarter together.

We do this to save our customers money and time, but we also do it to save our planet.

To tackle the Climate Emergency, we deliver innovative energy and retrofit solutions that reduce the carbon footprint of homes at scale.

We work closely with social housing providers, local authorities, and delivery partners to help them understand what their buildings need to achieve net zero.

This role offers the opportunity to make a real impact in driving sustainable energy solutions.

You’ll work closely with the Retrofit Coordinator and other technical colleagues to produce high‑quality documentation, coordinate key activities, and support delivery across multiple retrofit projects.

• Review post‑installation handover and commissioning documentation for technical accuracy
• Upload project information to the Trust Mark Data Warehouse
• Track KPIs to support team resourcing and monitor delivery performance
• Keep up to date with developments in retrofit regulations and standards, including PAS 2035 and SAP methodology
• Share suggestions for process improvements to enhance MTIP efficiency
• Balance your independent workload with wider team collaboration, to meet weekly and team delivery targets
• Support the on‑site inspection team when needed
