Whole-House View
A retrofit assessment looks at your entire property — fabric, heating, ventilation, and renewables — not just individual measures.
Prioritised Improvements
You get a clear, prioritised list of improvements ranked by cost-effectiveness and impact on energy use.
PAS 2035 Compliant
Our assessments are carried out by accredited Retrofit Assessors and comply with PAS 2035 — required for many grant-funded schemes.
Grant Pathway
A compliant assessment is the first step to accessing ECO4, Great British Insulation Scheme, and other government funding.

- Guidance on applicable grants and funding
- PAS 2035 compliant documentation
- Report delivered within 24–48 hours
Fabric First
We assess insulation, windows, doors, and airtightness — the building fabric that determines how much heat your home loses.
Heating Systems
Current heating efficiency, hot water systems, and the suitability of your property for heat pump or solar thermal upgrades.
Ventilation
Adequate ventilation is critical when improving airtightness. We assess current provision and recommend improvements where needed.
Renewables Potential
We assess the potential for solar PV, solar thermal, and other renewable technologies at your property.
Common Questions
What is a retrofit assessment?
A retrofit assessment is a detailed survey of your property that identifies the most effective improvements to reduce energy use and carbon emissions. It covers insulation, heating, ventilation, airtightness, and renewable energy options.
What is PAS 2035?
PAS 2035 is the UK standard for domestic retrofit. It sets out a framework for assessing, designing, and installing energy efficiency improvements. Compliance is required to access most government-funded retrofit schemes.
Do I need a retrofit assessment before installing solar or a heat pump?
Not always, but it's strongly recommended. A retrofit assessment ensures your property is suitable and that improvements are installed in the right order — for example, improving insulation before upgrading heating.
How long does an assessment take?
A typical domestic retrofit assessment takes 2–3 hours on site, followed by a written report delivered within 5 working days.
Is a retrofit assessment the same as an EPC?
No. An EPC gives a snapshot energy rating. A retrofit assessment is a much more detailed analysis that produces a Medium Term Improvement Plan (MTIP) with specific, costed recommendations.
