How to Manage a TrustMark Lodgement Efficiently

TrustMark lodgement is a critical step in the PAS2035 retrofit process. Whether you're coordinating a full retrofit scheme or managing individual property upgrades, understanding how to lodge documentation correctly with TrustMark will streamline your project timeline and reduce the risk of compliance issues.

Understanding TrustMark Requirements

TrustMark is the government-backed quality scheme for retrofit work in the UK. Under PAS2035, retrofit coordinators must ensure that all work meets quality standards and is properly documented. Before submitting any lodgement, confirm that:

• Your organisation holds a valid TrustMark registration
• The retrofit measures fall within your registered scope
• All operatives and surveyors are appropriately qualified
• The retrofit plan aligns with PAS2035 standards

Each retrofit project requires lodgement documentation that proves compliance with the retrofit standard. This is distinct from the retrofit assessment and retrofit plan—lodgement confirms that works have been completed to specification.

Preparing Your Lodgement Documentation

Proper preparation is essential. Gather the following before contacting TrustMark:

• Retrofit assessment report — the baseline energy assessment and identification of suitable measures
• Retrofit plan — detailed specifications for all proposed works
• Site photographs — before, during, and after images showing work completion
• Completion certificates — for gas, electrical, and heating system work where applicable
• Operative records — evidence of qualified personnel undertaking work
• Quality assurance documentation — inspection reports and sign-off records
• Product datasheets — for all materials and systems installed

Organise these documents chronologically and cross-reference them against the retrofit plan. Inconsistencies between planned and actual works must be clearly documented and justified, particularly if deviations from the original plan have occurred.

Common Documentation Gaps

Most delays stem from preventable gaps in submission packages. Be aware of these frequent issues:

• Missing retrofit coordinator sign-off — ensure the designated retrofit coordinator has reviewed and authorised all documentation
• Incomplete operative details — names, qualifications, and registration numbers must be clearly stated for all personnel involved
• Vague deviation explanations — if works differ from the retrofit plan, provide clear technical justification
• Poor photograph quality or coverage — images must clearly show the work completed; blurry or partial views will be rejected
• Missing energy performance data — calculations showing how measures contribute to the retrofit target must be included

Timing Your Submission

Plan your lodgement submission strategically. Ideally, lodge documentation within 4 weeks of practical completion. This window allows you to gather all evidence while work details remain fresh and any remedial work can be completed quickly if requested.

Avoid batch submissions at month-end, as TrustMark processing times extend during peak periods. Mid-month lodgement generally receives faster turnaround. Also consider seasonal delays—summer months often see higher volume submissions from spring and early summer projects.

The Review Process

After submission, TrustMark will conduct a desktop review of your documentation. This typically takes 10-15 working days. They will verify:

1. Compliance with PAS2035 retrofit standard requirements
2. Appropriate installer qualifications for the measures completed
3. Energy calculations and measure specifications
4. Completeness of quality assurance records
5. Alignment between retrofit plan, execution, and evidence provided

If TrustMark identifies deficiencies, they will issue a request for further information. Respond promptly—most requests can be resolved within 5-10 working days if you maintain organised records and responsive communication channels.

Post-Lodgement Responsibilities

Once TrustMark approves your lodgement, maintain copies of all documentation for the retrofit coordinator's records. This evidence may be needed for:

• Warranty claims or disputes
• Local authority building control queries
• Future retrofit assessments on the same property
• Scheme audits or investigations

Retain documentation for a minimum of 6 years in accordance with building control records retention requirements.

Efficient Workflow Practices

Streamline your process by:

• Creating a standardised checklist for each retrofit project
• Assigning documentation responsibility to specific team members early
• Conducting quality assurance checks before final compilation
• Maintaining templates for common documentation requirements
• Building communication protocols with TrustMark for clarification queries

Efficient TrustMark lodgement requires attention to detail, early planning, and comprehensive record-keeping throughout the retrofit project. By understanding requirements upfront and maintaining organised documentation, you'll minimise delays and ensure full compliance with PAS2035 standards.
