What format do you provide outputs in?

We provide digital outputs in Coordinator‑friendly formats, typically PDF reports and structured data files, ready to feed into your Improvement Plans.

What evidence do you collect?

We collect detailed RdSAP data, occupancy information, condition and ventilation notes, plus a full set of labelled photographs and supporting measurements.

How long does a retrofit assessment take?

A typical domestic retrofit assessment takes around 1.5–3 hours on site, depending on the size and complexity of the property.

How quickly can you return the assessment data?

In most cases, we return completed assessment packs within 2–5 working days. Faster turnaround can usually be arranged by agreement.

Do you work with all Retrofit Coordinators?

Yes. We regularly support independent and organisation‑based Retrofit Coordinators and are happy to work to your preferred processes and templates.

PAS 2035 is the UK standard that sets out how energy efficiency improvements to existing homes should be assessed, designed and delivered to ensure safe, effective and long‑lasting results.
