Retrofit and Energy Efficiency

The evidence that survives the audit.

PAS 2035 compliance requires documented evidence at every stage of the retrofit process. 360 capture creates an immutable, timestamped visual baseline that protects your funding, your programme, and your reputation.

The problem

19 million homes need retrofitting. The evidence chain is held together with phone photos and spreadsheets.

The UK needs to retrofit 900,000 homes a year. Current rates sit around 100,000 to 150,000. The bottleneck is not just capacity. It is the documentation burden that slows every project down.

Before/after evidence on phones

Photos taken on personal devices, matched to properties in spreadsheets. No location context, no timestamps you can trust.

Multiple trades, no single source

Insulation, windows, heating, ventilation. Each contractor captures their own evidence in their own format. Nobody shares.

QA relies on installer photos

Quality assurance depends on the installer choosing what to photograph. Selective evidence is not evidence.

Broken handovers between roles

Retrofit Coordinators, Assessors, Designers, Installers, Evaluators. Five roles, five different systems, five versions of the truth.

Audit trails assembled after the fact

When Ofgem or DESNZ request evidence, teams scramble to reconstruct records from emails, folders, and memory.

Repeated tenant disruption

Assessors visit. Designers visit. Installers visit. Evaluators visit. The same property accessed again and again for data that already exists.

PAS 2035 compliance

One capture supports the full PAS 2035 documentation chain.

PAS 2035:2023 defines the whole-house, fabric-first approach to domestic retrofit. AIM maps directly to the five stages that every compliant project must document.

Stage 1

Pre-assessment baseline

Walk the property with a 360 camera before any works begin. Every room, every surface, every defect captured in its original state with a timestamp.

Stage 2

Design reference

The Retrofit Designer accesses the digital model remotely. Measurements, room layouts, existing conditions; all available without a site visit.

Stage 3

Installation evidence

Capture before, during, and after each measure. Pin evidence to the exact location in the digital model. No more unattributed photos in folders.

Stage 4

Handover documentation

A complete visual record of the property at every stage, accessible to every role in the PAS 2035 chain. One platform, one version of the truth.

Stage 5

Evaluation and monitoring

Compare the property over time. The Retrofit Evaluator can verify outcomes against the original baseline without scheduling another visit.

Comparison

Traditional retrofit documentation vs. AIM

Without AIM

  • Evidence capture: phone photos sorted into folders by address, date guessed from file metadata
  • Coordination: email chains between Assessors, Designers, Installers, and Evaluators
  • Quality assurance: installer selects which photos to submit, no independent verification
  • Audit trail: assembled retrospectively when funding body requests it
  • Tenant access: separate visits for assessment, design, installation, and evaluation
  • Clawback risk: 8 to 12% of measures rejected on evidence grounds

With AIM

  • Evidence capture: 360 walk-through, every surface documented, timestamped and geolocated
  • Coordination: all PAS 2035 roles access the same digital model, same platform
  • Quality assurance: complete visual record, nothing selectively omitted
  • Audit trail: exists from day one, immutable, always accessible
  • Tenant access: one capture visit replaces multiple data-gathering appointments
  • Clawback risk: evidence exceeds every current funding body requirement
MEES compliance

EPC deadlines are approaching. Digital records make retrofit planning practical.

The Minimum Energy Efficiency Standards already require EPC E. The proposed move to EPC C by 2028 to 2030 will affect millions of properties. Fines reach £30,000 for residential and £150,000 for commercial non-compliance.

A digital model of your stock gives you the baseline to scope retrofit works, prioritise spend, and track progress towards compliance targets. No more estimating from incomplete records.
How it works

Three steps. One visit. Permanent evidence.

01

Capture

Walk the property before works begin. A 360 camera captures every room, every surface, every detail. As quick as it takes to walk around.

Before works
02

Document

Tag retrofit measures, pin evidence to specific locations in the digital model, and link before/during/after states. Every PAS 2035 role works from the same record.

During works
03

Evidence

A timestamped, immutable visual record for every property. Ready for Ofgem, DESNZ, or TrustMark lodgement. The evidence exists before anyone asks for it.

After works
Proven results

Annual savings
Eliminated return visits and duplicated data collection
30s
Remote measurement
Any measurement, any property, from a desk. Not a 2 to 3 hour site visit.
Zero
Return visits
Unlimited users access the same digital model. No per-seat licensing.

Protect every retrofit project from day one.

One capture per property. Immutable evidence for every funding body. Start building your audit-ready baseline on the next site visit.
