According to PAS2035:2023, what changes have been made to the qualifications required for retrofit designers?
The qualification requirements for retrofit designers have changed significantly. Previously, a Retrofit Coordinator (RC) could carry out retrofit design for Risk Path A & B projects. However, under the new guidelines, this role must now be carried out by a specialist or a trained designer. This ensures that the design work meets the highest standards for energy efficiency and safety.
Under PAS2035:2023, what is the deadline for completing and fully installing projects such as ECO4, GBIS, HUGS, and self-funded initiatives?
All projects such as ECO4, GBIS, HUGS, and self-funded projects must be completed and fully installed by 30th March 2025. Additionally, lodgements must be carried out no later than 20 working days after installation.
Is PAS2035:2023 mandatory for all retrofit projects?
Yes, PAS2035:2023 is a mandatory standard for retrofit projects in the UK that aim to receive public funding or need to meet specific energy performance requirements under government regulations.
What does Retrofit mean?
The UK Government has identified the retrofit of buildings as a key lever in their low carbon strategy to achieve 68% carbon reduction by 2030. All affordable homes will be required to achieve a minimum EPC of C by 2030. All ECO funded refurbishment projects are required to achieve full compliance with PAS 2035:2019 from July 2021 with a 20% funding uplift for projects that comply before the deadline.
PAS 2035:2019 (Specification for the Energy Retrofit of Domestic Buildings) is revolutionising the refurbishment of buildings. Over the last 30 years energy efficiency programmes have focussed on single measures (i.e.: cavity wall insulation or window replacement, etc.) but all future programmes now require a holistic solution designed to suit the specific building type.
To comply with PAS 2035, a qualified Retrofit Coordinator must be employed to provide a 'Whole House Retrofit' solution.
What are the benefits of retrofit work?
Retrofitting existing buildings will allow individuals and businesses to save money and be more sustainable. It will let people across the UK live in warmer and healthier homes. Crucially, it will help our industry, and the country as a whole, decarbonise.
