This would be followed up by an orientation call with Harshad Patel at Synergy Training Centre, about what’s involved, the ABBE entry requirements, and what the commitments are once signed up via the funding.
This year-round e-learning course is aimed at professionals in the construction industry; built environment and those involved in the energy efficiency sector who would like to understand how the PAS 2035 framework could add robustness to their projects and those who would like to become an accredited Retrofit Coordinator.
The course provides the in-depth technical detail essential to understanding low carbon retrofit and a working knowledge of the PAS 2035 process and framework. The course enables students to become confident and proficient in retrofit coordination in order to help deliver PAS 2035 compliant projects.
The Level 5 Diploma qualification is aimed at those already familiar with retrofit and project management.
This route uses ABBE awarding body, and as such candidates will need to meet the entry requirements for ABBE’s Level 5 Diploma in Retrofit Coordination and Risk Assessment qualification.
Students will need to be familiar with:
Students will also need to have experience of working in construction or the built environment for a minimum of 2 years within the past 3 years.
As well as having the knowledge and experience mentioned above, candidates would also need to provide evidence that they meet one of the following criteria:
In order to undertake one of our courses you will need to become an AECB member. We recommend logging in to your AECB membership account ahead of applying, to make the process as smooth as possible.
It can also be helpful to refer to the PAS 2035 guidance document alongside the course. Please download your free copy here. However, this is not essential, as the course itself provides enough understanding.

If you don’t currently want to become proficient in understanding the Retrofit Coordinator role, you can choose to join our Government recognised AECB CarbonLite™ Retrofit Foundation course to learn holistically about the retrofit process including how to develop your understanding of heat, ventilation and moisture in existing buildings, awareness of the issues that can arise from repair and and how to make informed decisions, and gain knowledge in how to reduce the performance gap.
This route to achieve the Level 5 Diploma qualification involves two stages.
The first stage of the programme is to complete the AECB CarbonLite™ Retrofit Coordination course (CLRc).
The content in our AECB CarbonLite™ Retrofit Coordination is attuned to deep low energy retrofit, carbon costing, and promotes the use of the Passive House Planning Package (PHPP) with a focus on reducing the performance gap and introducing AECB stock modelling.
The modules follow the order of the PAS 2035 stages.
The course modules are :
• Introduction
• Preliminary Considerations
• Retrofit Risk Assessment
• Dwelling Assessment
• Technical Information relevant to the Dwelling Assessment
• The Retrofit Design Stage
• Air Tightness and Ventilation
• Improving the building fabric – Floors and Roofs
• Improving the building fabric – Walls and Windows
• Improving the Building Services
• Renewable Energy Systems
• Improvement Option Evaluation and Medium Term Retrofit Plans
• Working With Installers
• Post-installation stages
• Technical information relevant to the post-installation stages
Following completion of our course, students will move on to a separate assessment stage with Synergy Training Centre who will supplement what students have learned on our course with the Level 5 assessments, top up tutoring and certification elements. (please see the ‘Course Approach’ section for more details about stage 2)
If you are not already a member of the AECB, you will first need to join the AECB, you can choose your appropriate membership level, and you can then apply to the programme.
This route to achieve the Level 5 Diploma qualification involves two stages.
Stage 1 is the online AECB CarbonLite Retrofit Coordinator course takes on average 105 hours of fully online, self-directed learning.
Stage 2 is a separate assessment stage that follows on from completion of our CLR Coordination course with the independent centre, called Synergy Training Centre, and ABBE awarding body.
The separate assessment stage includes:
Synergy Training Centre will keep track of your progress on our course and will contact you to arrange your participation in this assessment stage following completion of our course.
It is recommended to progress to the assessment stage within the first three months of completing stage 1, and Synergy Training Centre will assist you to complete your qualification within this timeframe if possible. However, Stage 2 must be taken within a year of completing Stage 1.
Please take a look at the Synergy Training Centre Learner Agreement for their terms of service.

PAS 2035 was sponsored by the UK Government’s Department for Business, Energy and Industrial Strategy (BEIS). This is the key document in a framework of new and existing standards on how to conduct effective energy retrofits of existing buildings, it covers how to access dwellings for retrofit, identify improvement options, design and specify Energy Efficiency Measures (EEM) and monitor retrofit projects.
The standard drives the ‘whole house approach’ including the ‘fabric first’ methodology. It defines the qualifications and responsibilities of individual retrofit roles and respective activities required prior to and post EEM installation. It includes a risk assessment process that builds incrementally robust requirements depending on what measures and type of building that the retrofit project is assessed to fall within.
The PAS 2035 framework needs to be followed to draw down specific government funding for retrofit projects. It stipulates that Retrofit Coordinators need to register with TrustMark to be able to Coordinate such funded projects. The management of the project must be compliant with the PAS 2035 and its requirements.
PAS 2035 is inextricably linked to PAS 2030 (for installers), which is the standard to which all energy efficiency installers must be certified and compliant.
The current Technical Author for the 2023 update of the PAS 2035 document is Dr Sarah Price. Sarah is also one of the writers of our Retrofit Coordinator course.
