Damp and mould guidance: what building industry contractors need to know

“Damp and mould in the home are not the result of ‘lifestyle choices’, and it is the responsibility of landlords to identify and address the underlying causes of the problem, such as structural issues or inadequate ventilation.” — The Rt Hon Steve Barclay MP, Secretary of State for Health and Social Care and The Rt Hon Michael Gove MP, Secretary of State for Levelling Up, Housing and Communities.

The UK government released refreshed damp and mould guidance for landlords in September 2023. Housing providers are now directly responsible for damp and mould control in rented housing.  This government guidance clearly communicates a “zero tolerance” attitude to mould in all sectors of the rented housing market. This aligns with current building industry attitudes.

The reality is this:

Not every landlord in England is positioned to deliver this kind of service.

Building professionals of all types need to be prepared to inform and provide the services that landlords now know they urgently need. Even if you’re not directly involved with damp remediation, awareness of the causes of damp and mould are paramount.

Compliance requires comprehensive prevention, regular inspections and speedy fault resolutions. It applies to everyone who provides accommodation as a service:

  • Private landlords and management agencies
  • Temporary accommodation providers
  • Providers of accommodation that is tied to a job
  • Social landlords registered with the Regulator of Social Housing (RSH)

Anyone involved with any element of damp remediation can become a part of the solution.

Plumbers at the scene of a leak should be able to directly advise landlords of the next steps they can take to prevent fostering a damp and potentially mouldy environment.

Electricians called in to fix electrical systems following a leak should be able to advise landlords on the state of the internal wall.

Carpenters should be able to spot the warning signs of damp when they’re called in to hang doors or install shelving.

Plasterers should be able to determine the causes of existing damp plaster when replastering and be able to let landlords know if the problem is likely to recur.

Interior decorators can advise tenants of the best way to plan their rooms to allow maximum air circulation, preventing damp and mould before it has a chance to start growing.

A HVAC installer should be able to advise on the best way to prevent damp conditions with appropriate ventilation measures.
