When I sat down with Mark Thompson, a seasoned building inspector with over two decades of experience, I was eager to delve into the intricacies of how energy performance and damp issues intertwine within UK buildings. Our discussion soon led to the Standard Assessment Procedure (SAP) calculations, which play a pivotal role in evaluating a building’s energy performance.

Mark began by explaining the significance of SAP calculations in modern-day construction and renovation. “The SAP is like a report card for a building’s energy efficiency,” he remarked with a wry smile. “It assesses everything from insulation and heating systems to cooling and ventilation strategies.”
As we sipped our coffees, Mark elaborated on how these calculations are not just theoretical exercises but have real-world implications, especially when it comes to tackling damp and mould issues. “A building’s energy performance directly impacts its susceptibility to damp and mould,” he said. “You see, proper insulation and ventilation are critical. They not only conserve energy but also prevent the excess moisture that often leads to these problems.”
Mark’s experience in the field has shown him that many homeowners and landlords are unaware of the interconnectedness of energy efficiency and moisture control. He shared a recent case where SAP calculations helped identify the root cause of a persistent damp problem in a Victorian-era home. “The house had been suffering from rising dampness, and the tenants were at their wits’ end,” Mark recounted. “After conducting SAP assessments, we realised that inadequate insulation and poor ventilation were compounding the issue.”
He went on to describe how improvements in insulation and ventilation, guided by SAP findings, transformed the living conditions in that home. “By installing appropriate insulation and upgrading the ventilation systems, we significantly reduced the moisture levels,” he stated. “It was a win-win: energy efficiency improved, and the damp issues were mitigated.”
Mark also touched upon the evolving landscape of building regulations in the UK, particularly concerning damp and mould. “Awaab’s Law has been a game-changer,” he noted, citing the 2023 reform aimed at safeguarding tenants from damp-related health hazards. “It has heightened the urgency for landlords to address these issues promptly.”
He emphasised the importance of landlords understanding their responsibilities under the Landlord and Tenant Act 1985. “Landlords need to ensure their properties are safe and habitable, free from damp and mould,” Mark pointed out. “If they ignore it, they not only risk legal action but also the health of their tenants.”
As our conversation continued, Mark highlighted some practical steps homeowners can take to prevent dampness, which are often overlooked yet essential. “Simple things like using lids on saucepans, avoiding drying clothes indoors without proper ventilation, and ensuring your tumble dryer is vented correctly can make a huge difference,” he advised.
Reflecting on his extensive career, Mark noted the shift in building practices towards more sustainable and energy-efficient solutions. “The push towards low-carbon heating systems and improved airtightness in new builds is encouraging,” he said, referencing the regulations set to take effect in 2025. “These measures not only enhance energy performance but also reduce the risk of damp and related issues.”
Before we wrapped up, I asked Mark about his outlook on the future of energy efficiency and damp solutions in the UK. “We’re moving in the right direction,” he concluded optimistically. “With continued education and adherence to regulations, we can create healthier, more energy-efficient homes.”
My conversation with Mark Thompson was an enlightening journey into the world of building energy performance and its impact on damp and mould issues. It underscored the importance of understanding and utilising SAP calculations to foster both energy efficiency and healthier living environments. For homeowners, landlords, and tenants alike, this knowledge is invaluable in tackling one of the most persistent challenges in home maintenance.
