What is PAS 2035?
PAS 2035, formally known as Publicly Available Specification 2035, is a framework developed by the British Standards Institution (BSI). Published in May 2019, this document outlines a comprehensive approach to retrofitting domestic buildings with an emphasis on long-term energy efficiency, occupant wellbeing, and sustainable construction practices.
Unlike previous standards, PAS 2035 takes a whole-house perspective, meaning it doesn’t treat retrofit issues in isolation. Instead, it connects energy performance upgrades with a property’s condition, occupancy patterns, and future needs. It forms part of the UK’s efforts to decarbonise housing stock and meet Net Zero by 2050.
In short, PAS 2035 is not just a set of rules, but a full strategy to retrofit homes intelligently and sustainably.
Why Was PAS 2035 Introduced?
Prior to the introduction of PAS 2035, the retrofit industry faced significant challenges stemming from a lack of structure, consistency, and accountability. Many projects were carried out in isolation, with little regard for the broader condition or future needs of the building.
- Single-measure installations led to unintended consequences (like mould after new insulation)
- No central role or individual was accountable for quality or outcomes
- Retrofit quality varied drastically
To combat this, the Each Home Counts Review (2016) called for a holistic and standardised approach to domestic retrofitting. PAS 2035 was developed in response and now operates alongside PAS 2030:2019, which governs the installation aspects of energy efficiency measures.
Key Aims of PAS 2035:
- Put residents at the heart of retrofit plans
- Ensure a data-driven approach to upgrades
- Introduce clear, competent roles throughout the process
Together, these aims ensure that retrofit works are not just technically sound, but also tailored to each household’s unique circumstances. By addressing the root causes of inefficiency and ensuring long-term thinking, PAS 2035 sets a new benchmark for quality and accountability in the UK retrofit sector.
When Did PAS 2035 Start?
PAS 2035 officially came into force in June 2019, with a transitional period allowing ongoing schemes under PAS 2030:2017 to continue temporarily. From July 2021 onwards, all publicly funded retrofit projects—like those under the ECO scheme (Energy Company Obligation)—must comply with PAS 2035.

Understanding the pas2035 Retrofit Revolution
Retrofitting is no longer just about loft insulation or double glazing. PAS 2035 champions a systemic view:
- Fabric-first approach: upgrade walls, roofs, and floors before tech
- Ventilation strategy: avoid damp and condensation
- Resident involvement: align with household habits
- Ongoing evaluation: make improvements last
By focusing on the building as an interconnected system, PAS 2035 ensures that retrofits are more than surface-level fixes—they’re durable, thoughtful, and built to improve performance over decades. This approach helps prevent unintended consequences, like damp or overheating, and ensures that each measure supports the others, rather than working in isolation.
What is the Difference Between PAS 2030 and 2035?
Although PAS 2030 and PAS 2035 are frequently mentioned in the same breath, they each serve distinct but complementary purposes within the retrofit process. Understanding their differences is key to delivering a fully compliant and high-quality retrofit project.
| Feature | PAS 2030 | PAS 2035 |
| Focus | Installation Quality | Whole-Retrofit Process |
| Applies to | Installers | Coordinators, Assessors, Designers |
| Requirements | Compliance with individual measures | Retrofit planning, design, assessment, and evaluation |
| Mandatory Roles | None specifically | Five (Coordinator, Designer, etc.) |
| Retrofit Plan | Not required | Mandatory |
| Resident Engagement | Limited | Core principle |
Together, they form an integrated, dual-standard framework that ensures retrofit projects are not only executed to a high technical standard, but are also planned, coordinated, and delivered in a way that prioritises long-term performance, occupant wellbeing, and regulatory compliance.
Is PAS 2030 Mandatory?
Yes, but with a caveat. PAS 2030 is mandatory for installers working under schemes like ECO4 or The Warm Homes: Local Grant.
However, compliance depends on whether the project is publicly funded. For privately funded projects, it’s best practice, though not legally required.
What Does PAS 2035 Certification Involve?
PAS 2035 certification serves as formal recognition that an individual or organisation is capable of delivering retrofit projects in full alignment with the specification’s processes and quality standards.

Common PAS 2035 Pitfalls and How to Avoid Them
Even the most well-intentioned retrofit projects can encounter challenges if the PAS 2035 process isn’t followed precisely. While the framework provides a robust system for quality assurance, missteps typically arise when teams rush, skip steps, or fail to communicate effectively.Understanding these common pitfalls is key to avoiding costly errors and ensuring long-term success.
- Incomplete assessments
Skipping even one element of the triage can derail the entire plan. Accurate data at the start is vital for effective decision-making. - Poor communication between roles
Use collaboration platforms and shared documentation to bridge gaps early. Miscommunication leads to conflicting decisions and duplicated efforts. - Ignoring resident lifestyles
Retrofit plans that don’t take daily behaviours into account often underperform. Resident involvement improves both satisfaction and outcomes. - Lack of ventilation planning
Every airtight measure needs a breathing counterpart. Neglecting this can lead to condensation, mould, and occupant discomfort. - Overlooking maintenance
A good retrofit includes a forward-looking maintenance schedule to protect the integrity and value of the investment over time.
✅ Pro tip: Include a resident briefing session in your retrofit plan—education equals cooperation. When occupants understand the “why” behind each upgrade, they’re far more likely to support and sustain its benefits.

📌 Bonus: It’s not about doing everything now—it’s about knowing what to do next and when, so the home continually improves in a coordinated and manageable way.
By taking this structured, future-facing approach, the Whole House Retrofit Plan helps to reduce long-term costs, eliminate duplication of work, and ensure that all retrofit measures are both technically and environmentally compatible. It’s not just a blueprint—it’s a vision for sustainable living.
What is a Medium-Term Improvement Plan?
The Medium-Term Improvement Plan (MTIP) is a distinctive and forward-thinking requirement within PAS 2035. Rather than focusing solely on short-term upgrades, the MTIP provides a long-range roadmap—typically covering a 20–30 year period—that guides how a home can be improved gradually and sustainably over time.
A MTIP is a unique PAS 2035 requirement. It:
- Spans up to 30 years
Outlines a realistic, phased timeline that reflects the evolving needs of both the property and its occupants. - Maps out sequential improvements
Ensures that each retrofit measure logically follows the last, preventing wasted time or rework. - Considers occupant needs, funding availability, and emerging technologies
Adapts to a household’s changing financial circumstances, government support, and future innovations.
🏡 Example: A low-income family can’t afford solar panels today, but a MTIP might plan for their installation in five years—after roof insulation has been upgraded and external funding becomes accessible.
The MTIP helps bridge the gap between immediate action and long-term vision, ensuring retrofit journeys are not only achievable but also strategically aligned. For homeowners, it offers clarity and confidence; for professionals, it supports structured delivery with measurable impact.
