PAS 2035: Understanding Retrofit Risk Paths

PAS2035, the Government’s new mandatory standard framework for all publicly funded retrofit energy efficiency measures, has introduced different assessment processes dependant on the work taking place.

This new risk assessment is performed independently by the new Retrofit Coordinator role and will allow the project in question to be categorised into one of three paths A, B or C.


Path A - low risk projects

The lowest risk path, A represents simple single or low risk measures (i.e.loft insulation) in standard properties.

It requires the Retrofit Coordinator to provide general advice independent of installer and conduct a whole dwelling assessment.

Handover to the installer includes general advice and basic monitoring is carried out.


Path B - medium risk projects

Path B would be required for multiple or higher risk measures installed in several properties.

Path B requires the Retrofit Assessor to provide additional detail in their assessment including fuel use SAP scores, appraisal of construction and occupancy, and a ventilation assessment.

The Retrofit Coordinator would then provide an Improvement Option Evaluation as well as a Significance Assessment, notes on traditional or historic buildings and overheating is also considered.

Detailed advice is passed onto installers during the handover.


Path C - high risk projects

Path C is required for:

  • Large scale projects
  • Multiple high risk measures
  • Conservation areas
  • Special planning approval

Path C contains significant additional competence and qualification requirements for those involved as specialist knowledge is likely to be needed.

As well as an Improvement Option Evaluation, Significance Assessment, notes on traditional or historic buildings and overheating, the Retrofit Assessor conducts an air permeability test.

A structural engineers report may also be required in Path C.
