A retrofit only works if every stage talks to the one before it: the assessment has to inform the design, the design has to survive contact with the installer, and the finished work has to actually deliver what was modelled. PAS 2035 puts one person in charge of making sure that happens – the Retrofit Coordinator. Without that role filled properly, the gaps show up exactly where you’d expect: at the handoffs between assessment, design and installation, as compliance failures, cost overruns or a retrofit that simply doesn’t perform as promised.
In this blog, you’ll learn:
- A breakdown of the Retrofit Coordinator’s role
- Why coordination is essential to every retrofit project
- How PAS 2035 compliance depends on getting this role right
- How our approach to coordination delivers seamless, high-quality retrofits
What is a Retrofit Coordinator?
A Retrofit Coordinator oversees the entire retrofit process from start to finish, acting as project manager for compliance as well as delivery. They’re responsible for ensuring all work is carried out safely, efficiently, and in full compliance with PAS 2035 and PAS 2030 – the UK standards governing domestic retrofit. The role exists specifically to reduce risk: without it, measures can be installed correctly on paper but still fail to deliver the energy performance improvement they were designed to.
The Coordinator’s main job is aligning and auditing the work of the retrofit assessors, designers and installers, checking that each step meets the project’s objectives and regulatory requirements. Whether overseeing a small-scale scheme or a portfolio of hundreds, the Coordinator makes sure the project runs smoothly and reaches the best energy efficiency outcome the properties can realistically achieve.
For how this role differs from a Retrofit Assessor or Retrofit Designer, see PAS 2035: What is it, and Why Does it Matter? and Retrofit Assessors: What Do They Do?
What Does a Retrofit Coordinator Do?
A Retrofit Coordinator’s job is broader than standard project management – it combines technical expertise, compliance oversight and risk management into a single point of accountability for the whole retrofit. The core functions are:
- Managing the retrofit process: overseeing seamless collaboration between everyone involved, and developing and managing detailed retrofit plans so the whole team works towards common objectives.
- Ensuring PAS 2035 and 2030 compliance: confirming that assessment, design, installation and post-evaluation all comply with the standards, safeguarding short- and long-term performance.
- Options appraisal (optioneering): evaluating and prioritising the available improvement measures for a property via an Improvement Option Evaluation (IOE), before design work is specified.
- Medium-Term Improvement Plans (MTIPs): setting out a phased, prioritised improvement pathway for a property or portfolio, sequencing measures over time rather than treating retrofit as a single one-off intervention.
- Risk management: identifying technical, financial and logistical risks early, and advising on mitigation to keep the project on track and in budget.
- Liaising between stakeholders: acting as the central point of contact between clients, contractors and other parties, maintaining transparency and keeping everyone aligned to the same standards.
- Monitoring progress and quality control: carrying out regular site visits and quality checks throughout to avoid performance gaps.
- TrustMark lodgement: lodging completed, compliant work through TrustMark – the national database that logs retrofit work and protects a property’s long-term asset value – once installation and post-evaluation are signed off.
- Post-retrofit evaluation: reassessing the property’s energy performance after installation, identifying and rectifying any performance gaps, and confirming the project met its goals.
Retrofit Coordination assisted by a qualified coordinator ensures that a project is carried out to the highest standard whilst mitigating any risks associated with combining certain improvements and understanding building physics when delivering a successful retrofit. The project is delivered in a considered manner – this means funds are well allocated to obtain the best result possible, and reduce the impact of each property on the planet and the occupant’s wallets.

The Importance of PAS 2035 in Retrofit Coordination
PAS 2035 sets out a structured framework for how retrofit projects should be conducted, covering every phase. The Retrofit Coordinator ensures that framework is followed, so the energy-saving measures installed are effective and durable in the long term.
Compliance with PAS 2035 also protects against common problems: poor-quality installations, measures that don’t deliver as promised, and miscommunication between teams. The Coordinator’s oversight keeps the process methodical, efficient and accountable.
Accreditation and TrustMark: lodgement isn’t something anyone can do – it requires holding the relevant PAS 2035 Retrofit Coordinator qualification and being registered with a recognised certification body first. On funded schemes, that lodgement isn’t optional; it’s what confirms to the funder that the work was overseen to standard.
Case Study: Retrofit Coordination for the Warm Homes: Local Grant
Shropshire Council needed a technical partner who could sit above a five-installer supply chain, not inside it. We delivered independent PAS 2035 retrofit coordination across around 50 rural properties, many of them traditional solid-stone homes within Conservation Areas, and five installers:
What Sets Our Retrofit Coordinators Apart
Our coordinators work from day one with BEE’s own in-house retrofit assessors, rather than auditing a third party’s data after the fact – so the assessment feeds straight into coordination without the handoff gaps a separate assessor and coordinator can introduce. That approach was recognised with Supply Chain Partner of the Year at the 2025 Unlock Net Zero Awards. Every coordinator holds the relevant PAS 2035 qualification and TrustMark registration required to lodge compliant work.
What’s Next?
Getting retrofit coordination right is what turns a collection of separately-managed trades into a retrofit that actually performs as designed – and protects your funding, your compliance position and your TrustMark lodgement in the process.
We carry out independent, end-to-end Retrofit Coordination for both privately funded and grant-funded projects, from small schemes to large-scale portfolios.
