Professional property assessments that identify energy-efficiency improvements, potential risks and suitable retrofit measures — the initial assessment required for a PAS 2035 project, carried out across the UK.
Free ECO4 eligibility check included
A retrofit assessor evaluates the property from both an energy-efficiency and building-condition perspective. Unlike a standard EPC, a PAS 2035 assessment is a more detailed inspection of construction, insulation, heating, ventilation and potential risks. The assessment can include:
The objective is clear, practical information that supports the next stage of a retrofit project.

PAS 2035 places importance on assessing the property before improvement measures are designed and installed. We gather the information needed to understand its existing condition and identify suitable opportunities.
The external inspection helps determine whether proposed improvements suit the property’s existing construction. It can consider:

Thermal imaging can also help identify areas where heat loss or thermal performance may require further investigation.
A structured overview of the property and potential improvement measures — the suitability of each measure depends on the property’s construction, condition and circumstances.
For eligible households, retrofit improvements may be supported through ECO4 funding or ECO4 Flex arrangements. Our consultancy reviews relevant eligibility information and identifies measures that may be suitable for funding consideration.
An assessment does not automatically guarantee funding — eligibility and funding decisions depend on the applicable scheme requirements and individual circumstances.

From first consultation to referral for coordination — a clear, practical route.
An EPC gives a rating and generic recommendations. A PAS 2035 retrofit assessment goes further — and for an ECO4-supported project it is required rather than relying solely on an existing EPC.
The initial assessment is the foundation for every retrofit decision that follows — so it pays to get it right.
Structured around the requirements of the retrofit process.
Assessors hold recognised qualifications and are PAS 2035 certified.
We assess construction, insulation, heating and ventilation — not just the existing EPC.
Where appropriate, thermal imaging supports identification of thermal-performance issues.
We can review potential eligibility and support relevant funding processes.
Recommendations presented in a structured format so owners understand priorities.
Discuss your property and requirements before proceeding with the assessment.

A structured assessment of your property that identifies potential retrofit measures and highlights the risks to consider before work begins. Book your PAS 2035 retrofit assessment today.
