How to Prevent Dampness and Mould – And The Cost of Doing Nothing 

10 June 2025

Damp and mould – often slow, silent, and insidious, their presence can silently erode the very fabric of your buildings, inflate repair bills, expose you to significant legal risks, lead to costly voids, and most importantly, jeopardise the health and well-being of your residents.

The consequences are far-reaching and, as we’re increasingly seeing, incredibly expensive. But with Awaab’s Law slated for implementation in October 2025, addressing damp and mould is no longer just a moral imperative; it’s rapidly becoming a strict legal obligation.

The Looming Financial & Reputational Storm

Should damp and mould take hold within your portfolio, the financial stability you’ve worked so hard to build could crumble – and fast. Consider the potential impact:

  • Reactive repairs: A staggering £3,000–£10,000 per property. These aren’t minor fixes; they’re often extensive and disruptive, from water leaks to electrical issues.
  • Legal claims: Facing legal action can cost you £10,000–£30,000+, not including the immeasurable damage to your professional reputation.
  • Void loss: Every week a property sits vacant due to damp and mould remediation can cost you £250–£500. This adds up quickly, especially across multiple units.
  • Reputational and regulatory risk: Beyond Awaab’s Law, the Social Housing (Regulation) Act 2023, HHSRS (Housing Health and Safety Rating System), and the Fitness for Human Habitation Act all underscore a heightened regulatory focus on tenant safety and property conditions. Failure to comply can lead to severe penalties and public scrutiny.

It’s clear: if damp and mould strike, the odds are stacked against you. The damage extends beyond monetary figures, impacting your standing as a responsible housing provider and the trust you’ve built with your tenants.

Beyond the Law: The Human Impact

While the financial and legal ramifications are stark, it’s crucial to remember the human element. Damp and mould are not just property issues; they are public health concerns. Respiratory problems, allergies, and weakened immune systems are all documented health risks associated with living in damp and mouldy environments, with black mould being particularly threatening. Proactively preventing these conditions isn’t just about avoiding penalties; it’s about safeguarding the health and dignity of the individuals and families you house. This is why it’s so vital to learn how to prevent dampness and mould across your portfolio.
