Keegans Highly Commended at the Retrofit Academy Awards 2025!

PAS2035:2023 introduces new requirements for risk management, quality control, and energy performance assessments. It emphasises a more holistic approach to retrofitting, including considerations for occupant needs and long-term sustainability.

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.
