The Ultimate Guide to Retrofit Remediation Services: How to Save Failed PAS 2035 Projects and Secure Funding

by | Jul 1, 2026 | News

Are you facing a retrofit project that has stalled due to compliance failures? Is your social housing portfolio at risk of losing vital funding because of poor installation quality? Look no further! At CPH Retrofit, we understand that the road to energy efficiency is rarely a straight line. Whether you are a social housing provider, a local council, or a national ECO installer, navigating the complexities of PAS 2035 can be a daunting task: especially when things go wrong.

As we move toward the Warm Homes Plan 2026 and the looming EPC C by 2030 mandate for landlords, the stakes have never been higher. A failed retrofit isn't just a technical headache; it’s a financial and regulatory liability. We are here to help you navigate the "gold standard" of retrofit remediation, ensuring your projects are saved, your funding is secured, and your buildings are future-proofed.

What is Retrofit Remediation?

In the simplest terms, retrofit remediation is the process of diagnosing and fixing under-performing or non-compliant energy efficiency projects. In the world of PAS 2035, remediation is more than just a quick repair; it is a forensic, whole-house approach to bringing a dwelling back into compliance.

When a project fails to meet the stringent requirements of the PAS 2035/PAS 2030:2023 framework, it often results in "performance gaps." This means the energy savings you modeled simply aren't happening, or worse, the building fabric is being damaged by moisture, damp, or poor ventilation.

Our remediation services act as a rescue mission for these assets. We use our 15 years of hands-on experience as former installers to look past the paperwork and identify the real-world root causes of failure.

Why PAS 2035 Projects Fail: Our 15-Year Insider View

Having started our journey as Retrofit Installers before evolving into consultants, we have seen it all. We know exactly where corners are often cut and where technical designs clash with reality. Most failures in current projects stem from a few critical areas:

  1. Poor Technical Monitoring: Without rigorous oversight, small installation errors: like gaps in External Wall Insulation (EWI) or incorrect loft insulation depth: can lead to massive thermal bridging.
  2. Ventilation Neglect: One of the most common mistakes is "sealing" a building without upgrading the ventilation. This is a recipe for condensation and mold. Our guide on the PAS 2035 process explains why this balance is non-negotiable.
  3. Inadequate Assessment: If the initial Retrofit Assessor misses a pre-existing damp issue or structural defect, the subsequent design is doomed to fail.
  4. Compliance Disconnect: Often, there is a gap between what the designer specifies and what the installer actually does on-site. Bridging this gap is essential for real-world delivery success.

The 2026 Landscape: Warm Homes Plan & EPC C by 2030

The introduction of the Warm Homes Plan in 2026 and the establishment of the Warm Homes Agency represent a major shift in how domestic retrofits are governed. The government’s mandate for all social and private rented housing to reach EPC C by 2030 means that remediation is no longer optional: it is a necessity for compliance.

If your current stock is not performing, you risk:

  • Clawback of Funding: Agencies like TrustMark and the Warm Homes Agency can and will claw back funding if projects don't meet PAS 2030:2023 standards.
  • Failed EPC Targets: You cannot reach EPC C with failing insulation or faulty heat pumps.
  • Reputational Damage: For councils and housing providers, tenant dissatisfaction due to damp or cold homes is a major risk.

We’ve seen how these factors change the way you handle social housing retrofit. Remediation is the key to turning a failing portfolio into a success story.

How to Save a Failing Project: The CPH Remediation Framework

When we are brought in to save a project, we don't just guess; we use data-driven, forensic techniques to provide a comprehensive solution. Our "Gold Standard" framework follows these four essential steps:

1. Forensic Assessment and Technical Monitoring

We begin with an in-depth evaluation that goes far beyond a standard EPC. We utilize C3 Technical Monitoring and Air Pressure Testing to identify exactly where air leakage and thermal loss are occurring. This allows us to see the "invisible" problems that caused the initial failure.

2. Compliance Review

We review all project documentation against the latest PAS 2035:2023 standards. We identify where the Retrofit Coordinator or Installer may have deviated from the required path. Our team knows the mistakes to avoid in PAS 2035 compliance, making us uniquely qualified to spot them.

3. Remedial Design and Measure Modelling

Once the issues are identified, we create a bespoke remedial plan. This might involve stripping back faulty EWI installations or redesigning the ventilation strategy. We use Retrofit Measure Modelling to ensure that these new interventions offer the best value for money and guarantee an uplift to EPC C.

4. Oversight and Handover

As your dedicated Retrofit Coordinator, we oversee the remedial works to ensure they are completed to the highest standards. We provide full documentation for TrustMark and funding bodies, giving you the peace of mind that your project is now fully compliant and your funding is secure.
