About Us

At Sero, we’re on a mission to decarbonise homes and communities. We design and deliver innovative retrofit solutions that reduce carbon emissions, improve comfort, and lower energy costs — all while supporting a fair transition to net zero.

We combine cutting‑edge technology, data‑driven insights, and deep sector expertise to make it easier for housing providers and homeowners to make sustainable improvements. Every role at Sero contributes directly to tackling the climate crisis and creating healthier homes for people and the planet.

About the Role

Our Project Coordinator roles sit at the heart of our retrofit delivery process. We’re building a talent pool for current and future opportunities across three levels — from Project Coordinator, to Domestic Energy Assessor (DEA), to Retrofit Assessor (RA).

Whether you’re just starting out in retrofit coordination or already qualified as a DEA or RA, this is your chance to play a vital part in transforming homes across the UK.

You’ll work closely with Retrofit Coordinators and technical experts to deliver PAS 2035‑compliant projects, coordinating technical information, producing high‑quality documentation, and ensuring every retrofit plan meets our exacting standards.

How You Will Help

You’ll contribute to our mission by:

• Supporting the delivery of compliant PAS 2035 projects and ensuring internal and external standards are consistently met.
• Reviewing property surveys and retrofit assessments, identifying and correcting data gaps or inconsistencies.
• Producing clear, structured technical write‑ups for Medium Term Improvement Plans (MTIPs), including sequencing logic, assumptions, and remedial works.
• Collaborating with technical colleagues to develop creative solutions for complex retrofit challenges.
• Uploading and managing data through the TrustMark data warehouse.
• Keeping up to date with SAP, PAS 2035, and related guidance to ensure compliance.
• Suggesting and implementing process improvements that drive efficiency and quality.
• Supporting on‑site inspections when required.

As you progress, you’ll have opportunities to gain professional qualifications such as the Domestic Energy Assessor (DEA) or Retrofit Assessor (RA) certification, moving along a clear pathway of professional growth at Sero.

To Hit the Ground Running, You’ll Need:

We’re interested in hearing from people at all stages of the journey, from aspiring retrofit professionals to qualified assessors. Depending on your level, you’ll bring some or all of the following:

• Experience working in or supporting energy efficiency, low‑carbon, or housing retrofit projects.
• Understanding of PAS 2035 and SAP methodology (or a willingness to learn).
• Strong data management and documentation skills, including confident use of Excel (lookups, pivot tables, charts, Power Query).
• Qualification (or commitment to work towards) as a Domestic Energy Assessor (DEA) and/or Retrofit Assessor (RA).
• Excellent attention to detail and a structured approach to problem‑solving.
• Strong written communication skills and the ability to explain technical information clearly.
• A collaborative mindset and enthusiasm for sustainability and innovation.
• A full UK driving licence for occasional site visits.
