Technical assurance and remediation support for retrofit projects.

ECOedge helps clients identify risk, review technical information, resolve compliance gaps and regain control where retrofit projects become complex, uncertain or difficult to progress.

We support councils, housing providers, landlords, installers and delivery partners with independent technical review, PAS 2035:2023 compliance support, evidence review, remediation planning and practical retrofit consultancy.

Remediation advice when projects need support

Retrofit risk needs to be identified before it becomes costly.

Retrofit projects can become difficult when assessments are incomplete, designs are unclear, evidence is missing, installation quality is uncertain, or residents report issues such as damp, mould, ventilation problems or poor comfort.

ECOedge provides independent technical scrutiny to help clients understand what is wrong, what is missing and what action is needed. Our role is to turn uncertainty into a clear route forward.

We review the information that affects compliance, suitability, buildability, resident outcomes and lodgement readiness, then provide practical advice that can be used by clients, coordinators, designers, installers and delivery teams.

Real-world retrofit issues need practical technical judgement.

Technical assurance is most valuable when there is a specific problem to understand, a risk to manage or a decision that needs clearer evidence. ECOedge supports clients with practical review and advice in situations where retrofit projects need closer control.

When the assessment does not support the proposed measures.

A Retrofit Assessment may be incomplete, inconsistent or missing key information on construction, condition, occupancy, ventilation, heating, damp, mould or access. ECOedge can review the assessment, identify information gaps and advise whether the proposed measures are suitable before design or installation progresses.

When existing design or coordination needs technical review.

Some projects need additional support where previous design or coordination work is incomplete, unclear, inconsistent or difficult to progress. ECOedge can review the available information, identify technical and compliance gaps, clarify what is needed and help clients move the project forward with stronger control.

When evidence is missing before lodgement.

Projects can stall late in the process when photographs, certificates, declarations, commissioning records, warranties or handover documents are missing or incomplete. ECOedge can review the evidence position, identify what is outstanding and help clients understand what is needed to move towards TrustMark lodgement readiness.

When residents report damp, mould or ventilation issues.

Retrofit works can create or expose issues where ventilation, moisture, heating use, airtightness, insulation, resident behaviour or existing property defects have not been properly considered. ECOedge can review the available evidence, identify likely causes and recommend practical next steps for investigation or remediation.

When solid wall insulation raises technical or performance concerns.

Solid wall insulation can be affected by property condition, exposure, detailing, ventilation, moisture movement, workmanship and maintenance. Where concerns have been raised, ECOedge can review available records, site evidence and property context to help clients understand risk, identify further investigation needs and consider proportionate remediation options.

When installation quality or performance is disputed.

Where measures appear to have failed, underperformed or been installed differently from the agreed design, ECOedge can review design records, site evidence, product information, photographs, handover documents and resident feedback to help establish what happened and what corrective action may be required.

Technical assurance services that make risk visible.

ECOedge provides targeted technical review and consultancy support across the retrofit process, helping clients identify risk, improve quality, resolve issues and maintain a clearer audit trail from assessment through to completion.

Check

Technical due diligence.

Pre-project or mid-project review of scopes, specifications, delivery models, contractor capability, compliance pathways and technical risk.

Check

Design and compliance review.

Review of Retrofit Assessments, IOEs, MTIPs, Retrofit Design packs, PAS 2035:2023 decisions, measure suitability and sequencing.

Check

Evidence and lodgement readiness.

Review of photographic evidence, certificates, commissioning records, handover documents, installer declarations and TrustMark lodgement readiness.

Check

Installation quality review.

Review of workmanship, measure interfaces, product suitability, sequencing, substitutions, commissioning and handover quality.

Check

Damp, mould and ventilation risk support.

Review of condensation, damp, mould, indoor air quality, ventilation adequacy, overheating and unintended consequences.

Check

Forensic review and remediation planning.

Investigation of failed, underperforming or disputed retrofit measures, with root-cause review and corrective action planning.

Assurance can be valuable before, during or after retrofit works.

Technical assurance can support early decision-making, live delivery control, pre-lodgement review or post-installation problem solving. The right review at the right time can prevent small gaps becoming larger programme risks.

1

Before works begin.

Assessment gaps, unclear design assumptions, unresolved damp or ventilation risks, uncertain measure suitability, and unclear procurement or funding requirements.

2

During delivery.

Installer queries, design changes, substitutions, resident concerns, evidence gaps, sequencing issues or installation quality concerns.

3

Before lodgement.

Completion evidence, certificates, warranties, commissioning records, photographs, declarations and handover documents need checking before submission.

4

After problems emerge.

Failed measures, underperformance, damp and mould complaints, poor comfort, resident concern, defects or disputed responsibility.

We check the information that determines whether retrofit will work.

Effective assurance depends on reviewing the information that drives technical decisions, delivery quality, resident outcomes and compliance. ECOedge looks across the full pathway, not just isolated documents.

Assessment and property risk.

Retrofit Assessments, property condition, occupancy, vulnerability, heating, ventilation, moisture, overheating, access and statutory constraints.

Design and measure suitability.

Design packs, specifications, measure interaction, sequencing, thermal bridging, ventilation, product suitability and buildability.

Installation and evidence.

Photographs, installer evidence, competency records, product datasheets, warranties, commissioning records and handover documents.

Compliance and programme control.

PAS 2035:2023 declarations, TrustMark evidence packs, lodgement readiness, tracker records, action logs and audit trail completeness.

When confidence has been lost, we help define the route back.

Some projects require more than a standard review. Where measures have failed, evidence is incomplete, residents are unhappy, damp or mould has emerged, or compliance is disputed, ECOedge can provide independent technical judgement and practical remediation advice.

Understand the issue.

Review documentation, evidence, property condition, installation history and resident concerns.

Identify the cause.

Consider design, sequencing, workmanship, ventilation, moisture, product suitability, handover and maintenance factors.

Define corrective action.

Set out practical recommendations, further investigation needs, responsibilities and steps required to restore compliance and performance.

Support follow-through.

Help clients manage evidence, communication, technical decisions and post-remediation review.

We support clients who need independent retrofit judgement.

ECOedge works with organisations and individuals who need practical technical assurance, clearer compliance control, issue resolution or independent advice on difficult retrofit decisions.
