What's it all about?

One of the most important roles in retrofitting buildings is that of the Retrofit Assessor. The course is all about how we conduct surveys and collect data about people’s homes. We know that bad retrofit always starts with bad assessment and we want to ensure that happens by training people appropriately. 

 The course focus is to upskill Domestic Energy Assessors to better understand retrofit and ensure they are skilled to carry out the task to the required standards.

The course has been designed to transform your knowledge and skills in this field. It is entirely aligned with PAS 2035 and the Retrofit Coordinator qualification.

 This is the right course for you if you want to develop a career as a PAS 2035 Retrofit Assessor – if you want to be part of the change and do it right.

Course information

The course is made up of nine modules that cover all aspects of retrofit assessment. Each module features extensive teaching materials, expert presentations, case studies and activities that are designed to give you an in-depth understanding of both theory and practice.

The course consists of 25 guided learning hours plus assessments to complete. You can expect to need 60 hours across the six-week duration of the course. 

Over the first four weeks learners are taught face-to-face and through our e-learning platform. Learners then complete three property reports over the following month before completing an End Point Assessment. 

  • Module 1 PAS 2035 and retrofit assessments
    Gives an overview of PAS 2035 and how this impacts on the Retrofit Assessor’s role. 
  • Module 2 Context of dwellings
    Looking at the areas that need to be addressed in preparation for carrying out a retrofit assessment. 
  • Module 3 Assessing the condition of a dwelling and recording any defects
    This includes recording of defects including leaks and cracks and how they are addressed prior to the installation of new measures. 
  • Module 4 The requirements of occupancy assessments
    The occupancy of a dwelling; the number of people who live there, ages, lifestyle patterns, etc. is a key part in the successful planning of a retrofit. 
  • Module 5 Ventilation requirements of a dwelling
    Calculating ventilation to ensure there is fresh air for breathing, as well as for removing and reducing pollutants in the home along with controlling the amount of moisture in the air and thus reduce the risk of condensation and problems such as mould growth. 
  • Module 6 Energy performance of a dwelling
    This module covers estimating energy usage and cost, and carbon dioxide emissions using industry models, such as the Standard Assessment Procedure (SAP) or the Passive House Planning Package (PHPP). 
  • Module 7 Significance of a dwelling
    This module covers the classification of a building, i.e. ‘traditional’ or ‘protected’ and reporting on
    its age, built form, setting and so on. 
  • Module 8 Retrofit assessment reports
    This module includes a virtual retrofit assessment of a domestic dwelling, including being able to
    inspect for defects. Followed by the completion of the assessment report. 
  • Module 9 Retrofit advice to customers
    PAS 2035 spells out what retrofit advice needs to be provided on a project, and by whom, so this
    module sets out what the Retrofit Assessor’s responsibilities are in this respect. 

As a regulated qualification, the Level 4 Award in Domestic Retrofit Assessment has some specific eligibility criteria. The minimum requirement is a Level 3 Domestic Energy Assessor qualification.

The course is assessed via: 
  • invigilated multi-choice assessments 
  • property assessment 
  • end-point assessment and professional discussion. 

Retrofit Assessors work in a range of organisations such as housing associations, local authorities, energy and utility companies and specialist retrofit companies. Many
are self-employed or set up their own businesses. Retrofit Assessors conduct an assessment
of a property and provide the Retrofit Coordinator and/or Designer with the data required to make informed decisions about retrofit measures.

Retrofit Assessors typically earn salaries of £18k – £25k when training. With experience and once qualified, they can expect salaries of £25k – £50k.

There are also career progression routes within the retrofit sector, such as Retrofit Coordinator, subject to further training. 

Please note fees are quoted for one year only.
