In this article, Installer Compliance Guide PAS2030 PAS2035, we will cover basic overview to help installers start to understand how they can begin to ensure compliance to PAS 2030 & PAS 2035 for Retrofit Projects. It is not an in-depth guide to how to do everything to ensure compliance to all relevant standards, guidance and industry codes of practice as that would be an encyclopaedic

1. Understanding PAS Requirements

PAS 2030: Covers installation standards for energy efficiency measures.
PAS 2035: Governs the whole-house retrofit process, including assessment, design, and coordination.

Key Roles:

Retrofit Assessor: Conducts property assessment.
Retrofit Coordinator: Oversees compliance and risk management.
Installer: Delivers measures to PAS 2030 standards.

2. Pre-Installation Compliance

✔ Check Accreditation

Ensure your company is registered with TrustMark and certified for PAS 2030 measures.

✔ Verify Retrofit Assessment

Confirm the assessment is complete and compliant.
Review the Improvement Option Evaluation (IOE) and design provided by the Retrofit Coordinator.

✔ Product & Measure Approval

Use only products listed in the design and approved under PAS 2030.
Confirm U-value calculations and ventilation requirements.

✔ Documentation

Collect and review:
- Retrofit Assessment Report
- Design Specification
- Risk Assessment
- Ventilation Strategy (if applicable)

3. During Installation

✔ Follow Design Exactly

Do not deviate from the approved design without Coordinator approval.

✔ Capture Evidence

Pre-install photos: Before work starts.
Mid-install photos: Key stages (e.g., insulation layers, fixings).
Post-install photos: Completed measure and finishes.

✔ Quality Checks

Ensure workmanship meets PAS 2030 standards.
Record any variations and report immediately.

4. Post-Installation Compliance

✔ Submit Documentation

Installation Checklist
Product Data Sheets
Commissioning Certificates
Ventilation Test Results (if required)

✔ Handover Pack

Provide homeowner with:
- Guarantee/Warranty
- Maintenance Instructions
- Energy Saving Advice

✔ Lodgement

Ensure all evidence is uploaded for TrustMark lodgement via the Retrofit Coordinator.

5. Common Pitfalls to Avoid

Missing photo evidence (pre/mid/post stages).
Using unapproved products.
Failing to follow ventilation requirements.
Incomplete documentation for office audits.

6. Support Available
