Retrofit Designer &/or Coordinator

Competitive Salary + Bonus + Benefits

A fantastic opportunity has arisen for a qualified and motivated Retrofit Coordinator and/or Retrofit Designer to join our growing team. This is your chance to take a central role in delivering high-quality, PAS 2035-compliant retrofit projects that make a real difference to people, places, and the planet.

We are a small but growing, award-winning sustainability consultancy with big ambitions. We work nationally from our office on Gloucester Road in Bristol, delivering retrofit, testing, and consultancy services to help improve building performance and reduce carbon emissions.

As a key part of our team, you’ll take ownership of retrofit coordination and/or design depending on your strengths and experience. As we’re a close-knit and agile company, there will be times when you’ll be expected to step beyond your role to support other teams and projects – whether that’s helping colleagues meet deadlines, improving internal processes, or contributing to wider company initiatives.

If you’re looking for a role where you can grow quickly, take real ownership, and help shape the future of a mission-driven business, we’d love to hear from you.

Key Duties

· Depending on your experience and focus, your role may include:

Managing and coordinating PAS 2035 retrofit projects from start to finish

· Producing detailed, compliant Retrofit Designs and technical specifications

· Carrying out or reviewing Improvement Option Evaluations and Medium-Term Plans

· Completing U-value calculations, thermal bridging assessments, and condensation risk analysis

· Supporting and coordinating with Retrofit Assessors, Installers, and Coordinators

· Ensuring compliance with TrustMark, PAS 2030/2035, and funding scheme requirements

· Helping develop and improve internal tools, processes, and QA procedures

· Contributing to knowledge sharing across the team and supporting junior colleagues

· Working flexibly to support other areas of the business where your skills are needed

Key Skills

We welcome applicants from both Retrofit Design and Retrofit Coordination backgrounds. You should have experience in some of the following areas:

· Qualified Retrofit Coordinator and/or Retrofit Designer (or actively working towards qualification)

· Solid knowledge of PAS 2035 standards and processes

· Understanding of domestic construction, building physics, and energy efficiency principles

· Experience with RdSAP, SAP, U-value calculators, and other design tools

· Knowledge of ventilation strategies, thermal bridging, and moisture risk

· Excellent written communication and documentation skills

· Ability to manage workflows, prioritise tasks, and communicate effectively with clients and colleagues

· Flexibility to adapt and pitch in across different teams when needed

· Familiarity with funded retrofit schemes (ECO, SHDF, etc.) is a plus

About you

· You care about making a difference – both to the environment and the people living in the buildings we retrofit

· You’re excited by the opportunity to join a small, agile, and ambitious company where your input counts

· You’re self-motivated, curious, and comfortable supporting other teams when needed

· You’re collaborative, communicative, and enjoy problem-solving in a team setting

· You’re looking for a role that offers not just career progression, but purpose and impact

We offer competitive salaries and a performance-related bonus scheme after the first year. We are committed to supporting your professional development through structured training, CPD, and career progression opportunities.
