Retrofit & PAS Services

YES delivers all roles within the PAS2035 framework so clients can rely on a single, trusted partner for the full retrofit journey

What is PAS2035?

PAS2035 is the national quality standard that guides how energy efficiency upgrades should be planned and delivered in existing homes. It was created to make sure retrofit work is carried out safely, consistently and in a way that genuinely benefits the people living in the property.
Instead of focusing on single measures in isolation, PAS2035 looks at the whole home and the people who live in it. This helps reduce the risk of problems like damp, mould or poor ventilation and ensures improvements work together to create a warmer, healthier and more energy efficient living space.
