Retrofit Assessments
IN accordance with pas 2035

What is PAS 2035?

PAS 2035 is the new comprehensive document in the retrofit standards framework. PAS 2035 essentially provides a specification for the energy retrofit of domestic buildings, and details best practice guidance for domestic retrofit projects.

What is the retrofit assessment process?

Once we have a confirmed retrofit assessment booked with us, we will contact the homeowner to get the following information:

  • Approximate age of the property
  • Number and age of extensions and any supporting documentation
  • Documents for rooms in the roof
  • Warranties and certificates, e.g. cavity wall and loft insulation, solar panels, extractor fans, boiler, hot water cylinder
  • Details about the heating and hot water systems
  • Last 12 months energy bills – gas and electricity

We ask that this information is ready for the date and time of the visit as this are crucial in helping us make an accurate assessment of the retrofit needs of the property.

The site visit

We will ask the homeowner about any issues or concerns they have about the property and collect and record the information needed

Energy assessment, floor plan, survey and data collection.

Our retrofit assessor will conduct an energy assessment, similar to the way in which an EPC is carried out but in much more detail. A detailed floor plan is created with accurate measurements of rooms, walls, windows and doors, not too different to our scale floor plans.

Condition report.

The condition report data collection will consist of making notes and recording information about the whole condition of the property, inside and out. Issues such as damp, mould and cracks in the building fabric will be recorded along with aspects relating to ventilation.

Occupancy assessment.

We want to know how the property is used, our assessor will go through a few questions on how you use your property and collect accurate information to later assess the level of energy savings that can be made.

The final report.

When the assessor is back in the office, the data collected on the site survey will be calculated and written up into the final reports using Elmhurst’s software.

We lodge the final report on the Data Warehouse and upload a copy to the Retrofit Coordinator.
