What is PAS 2035?

PAS 2035:2023 is a comprehensive set of guidelines aimed at improving the energy efficiency of homes across the UK.

Developed to ensure that retrofit measures such as insulation, heating systems, and window upgrades are implemented correctly and safely, PAS 2035:2023 is essential for enhancing the quality and performance of social housing.

Key Aspects of PAS 2035:2023

Background and Development

PAS 2035 was born out of the 2015 Each Home Counts review, commissioned by the government to address the high rate of failures in domestic retrofit projects. The review identified the need for a standardised approach to retrofitting, which led to the development of PAS 2035 to ensure future projects are successful and sustainable.

Scope and Standards

PAS 2035:2023 outlines the scope, process, requirements, standards, and claims of compliance for retrofitting social housing. This ensures that all retrofit projects are consistent and adhere to a high standard of quality and safety.

Transition from PAS 2035:2019

The 2023 version supersedes PAS 2035:2019, which remains valid until the end of March 2025. This allows a transitional period for stakeholders to adapt to the new guidelines.

Whole-House Retrofit Approach

One of the core principles of PAS 2035:2023 is the “whole-house” retrofit approach. This means evaluating and improving the entire building rather than focusing on individual components.

This comprehensive method ensures that all retrofit measures work together harmoniously to enhance the overall energy efficiency of the property.

Fabric First Strategy

PAS 2035:2023 emphasizes a “fabric first” approach, prioritizing repairs, addressing damp issues, and implementing energy-saving upgrades to the building fabric before other measures.

This includes, wall, floor, and loft insulation, energy-efficient windows and doors, efficient or renewable heating systems, solar photovoltaics, and draughtproofing.

Ventilation and Health

Effective ventilation is a critical element addressed by PAS 2035:2023. Proper ventilation is essential to prevent mould and damp issues following retrofit work on a property.

The guidelines ensure that each property undergoes a full ventilation review and necessary upgrades, thereby maintaining healthy indoor air quality and living conditions.

PAS 2035 for Retrofit of Social Housing

PAS 2035:2023 plays a crucial role in social housing for several reasons:

Improving Energy Efficiency: Enhancing the energy performance of social housing reduces energy consumption, leading to lower energy bills for residents and contributing to carbon emission reduction targets.

Ensuring Quality and Compliance: By adhering to PAS 2035, housing providers can ensure that retrofit projects meet high standards of quality and safety.

Enhancing Resident Comfort: Energy-efficient homes provide more comfortable living environments and help alleviate fuel poverty for all residents of social housing.

PAS 2035:2023 provides a robust framework for the retrofitting of social housing, ensuring that projects are conducted to the highest standards, improving energy efficiency, and enhancing the wellbeing of residents.

What We Do

We’re committed to supporting the delivery of social housing retrofit projects to PAS 2035 standards, through our work with Housing Associations, Local Authorities, and Social Landlords.

We provide clear, transparent communication with our clients and stakeholders throughout each stage of every retrofit project, along with a proactive approach to implementing efficient and effective project delivery with our in-house retrofit services.

01 Retrofit Coordination

Our Retrofit Coordinators manage retrofit housing projects for our clients, ensuring PAS 2035 compliant energy efficiency and sustainability measures.

They work closely with our Retrofit Assessors, our in-house retrofit designers, and our clients, to lead retrofit projects from inception to completion.

02 Retrofit Assessment

We have a team of experienced, Trustmark accredited and qualified Retrofit Assessors, who undertake pre- and post-retrofit assessments, supported and managed by our in-house Retrofit Coordinators.

Our Retrofit Assessors produce comprehensive retrofit assessment reports tailored to the archetype and specific project requirements, so that we create the highest quality Retrofit Designs, which meet the needs of our clients and their residents.

03 Retrofit Design

Our in-house Retrofit Designers apply the principles of both fabric first and whole house retrofit, depending on the requirements of each client and project.

An integral part of every project, our design team models a range of potential improvements for the project, achieving optimal energy efficiency, indoor air quality and thermal comfort, to support increased energy efficiency and reduction in fuel poverty.
