What is PAS 2035?

PAS 2035 is the new over-arching document in the retrofit standards framework introduced following the recommendations of the Each Home Counts review.  PAS 2035 essentially provides a specification for the energy retrofit of domestic buildings, and details best practice guidance for domestic retrofit projects.

Background

It is evident that significant improvements need to be made within the energy efficiency of the UK’s building stock, if the country is to meet its global carbon commitments. In 2015 the government commissioned the Each Home Counts review to identify and tackle the high level of failure present in domestic retrofit, and to determine a better process for the retrofit of energy efficiency and renewable energy measures. PAS 2035 (PAS 2035:2019 Specification for the energy retrofit of domestic buildings) was introduced as a result of this review, with the backing of industry and the government department for Business Energy and Industrial Strategy (BEIS).

Following a transitionary period (expected to run until Jan 2021) the government have proposed to make compliance with PAS 2035 mandatory for all public funded projects. This could also include ECO funded retrofit projects.

How is PAS 2035 different?

This PAS embraces quality retrofit work eliminating problems associated with defects, shallow retrofit, accountability, poor design and performance gap. PAS 2035 delivers a whole building approach to the retrofit process, considering the home, environment, occupancy and the householders' improvement objectives when determining the most suitable measures to install. This eliminates the issue of retrofit work being considered in isolation which can unintentionally damage the overall building performance.

Moreover, five new retrofit roles have also been introduced within the PAS 2035 process, with clear responsibilities and accountabilities established to ensure that individuals deliver quality throughout. Elmhurst currently run training and schemes for two of these new roles, including the Retrofit Assessor and Retrofit Coordinator.

PAS 2035 and TrustMark

TrustMark Logo

TrustMark has been established as the new quality mark within the retrofit standards framework. This TrustMark is supported by an Industry Code of Conduct, a Consumer Charter and a framework of technical standards for retrofit. Users of the TrustMark Government endorsed quality scheme will be required to comply with PAS 2035 when undertaking any domestic retrofit work. Those who hold the TrustMark can demonstrate to consumers that they have the skills and knowledge to deliver the best practice standards and trading practices in the sector.

Retrofit Assessors

Retrofit Assessors are trained to undertake a retrofit assessment for dwellings in accordance with PAS 2035. The activities completed within the retrofit assessment include the production of an RdSAP assessment, a detailed floor plan, a condition report and an occupancy assessment.

The data collected from these sources is used by the Retrofit Coordinator to formulate a Medium-Term Improvement Plan. Accredited DEAs are well placed to become qualified Retrofit Assessors due to their extensive knowledge and experience with RdSAP methodology and assessment of existing dwellings.

Retrofit Coordinators

Retrofit Coordinators are required for all domestic retrofit projects in order to comply with PAS 2035. The Retrofit Coordinator occupies a vital project management role within the retrofit process and are needed to protect both the interest of clients and the public. They are responsible for overseeing a domestic retrofit project from inception to completion, and will liaise with building owners, and other retrofit project stakeholders in order to ensure effective project management.

A Retrofit Coordinator can prepare a Medium-Term Improvement Plan using data from retrofit assessments, to provide a scope for improvement over a 20-30 year period.

Elmhurst and PAS 2035

Elmhurst Energy operates a TrustMark approved Retrofit Assessor and Retrofit Coordinator scheme in accordance with PAS 2035. Members of these schemes can undertake work within domestic retrofit projects as TrustMark holders, and will be required to comply with the new standards. In addition to these schemes, Elmhurst can also provides relevant training for individuals who want to become qualified as either a Retrofit Assessor or Retrofit Coordinator.

PAS 2035 and ECO3

In October 2019 the Department for Business Energy and Industrial Strategy (BEIS) released the long-awaited outcome to the ECO3 (Energy Company Obligation) consultation.

Following the responses from industry the government has decided to incorporate the TrustMark Government Endorsed Quality scheme and the updated PAS standards (PAS 2035 and PAS 2030:2019) into ECO3. This means that all ECO measures will need to be completed by TrustMark registered businesses and, following an appropriate transition period, to the new and improved standards.

The government intends to bring the new regulations into force on 1 January 2020, when the supply chain (installers and delivery partners) can begin adopting then new PAS 2035 framework. This will then become mandatory from the 1st July 2021. However, those who adopt the new PAS framework early will benefit from a 20% uplift for all ECO3 measures delivered
