Damp and Mould Assessor Training

Elmhurst’s Damp and Mould Assessor Training equips you with the practical skills to competently assess damp and mould hazards in domestic properties and produce clear, professional reports.

With Awaab’s Law now in force (effective Monday 27 October 2025), social landlords face stronger requirements to act quickly and effectively when serious hazards are identified, particularly damp and mould, which can pose significant risks to health and wellbeing.

Elmhurst’s Damp and Mould Assessor Training is designed to help Domestic Energy Assessors (DEAs) build the practical competence needed to identify damp and mould risk, understand how ventilation and building performance contribute, and produce professional reports.

Why become a Damp and Mould Assessor?

Respond to increasing legislative demand

With the introduction of Awaab’s law, the hazards of damp and mould within properties have been brought to the forefront of the industry.

Broaden your service offering

If you are already a DEA or RA, this is a natural extension, supporting better whole-house decision making for landlords across ventilation, heating, moisture and building performance.

Boost your earning potential

By adding this competency, you can offer additional services that complement your DEA and retrofit work, helping you take on more jobs and increase your earning potential.

Support healthier, safer homes

Damp and mould can affect residents’ health, comfort and wellbeing. As an assessor, you can help improve living conditions by identifying risks early and supporting landlords with accurate information

Join Elmhurst’s Damp and Mould Competency Scheme

After completing the training, you will be eligible to join Elmhurst’s Damp and Mould Assessor scheme, the first of its kind in the industry, demonstrating your competence and professional standards. You will also gain access to our industry-leading software, technical support, our Find an Assessor directory and insurance cover for your work.

Why are Damp and Mould Assessments required?

Awaab’s Law and Increased Ventilation standard in social rented properties

Awaab’s Law is named after Awaab Ishak, who died in 2020 following prolonged exposure to mould in his family home. The case brought national attention to the consequences of failing to address damp, mould and underlying ventilation issues.  The law was introduced as part of the Social Housing (Regulation) Act 2023, establishing clearer expectations for landlords to take prompt action when hazards such as damp and mould are confirmed. These rules apply to all social rented housing and took effect on 27th October 2025, marking a major step forward in improving housing safety standards.

Damp and Mould Risk in Retrofit Projects

Damp, mould and condensation findings can inform the ventilation strategy for PAS 2035 retrofit projects, helping to ensure that fabric upgrades and increased airtightness do not lead to unintended consequences such as higher humidity and mould growth. As retrofit measures can reduce background ventilation, ventilation should be assessed and, where necessary, improved to manage indoor air quality and moisture effectively. Where instructed by a Retrofit Coordinator, damp and mould assessors can contribute by identifying moisture and condensation risk factors and providing findings that help inform appropriate ventilation measures.

What’s involved in undertaking a Damp and Mould Assessment?

Like a DEA assessment, damp and mould assessments involve a site visit to the property. However, rather than focusing on the home’s energy efficiency features, you will be assessing the condition of the building and the evidence available to understand damp and mould risk, alongside how the home is being used day to day. Typically, this includes:

• Identifying visible mould growth, damp staining and other moisture indicators
• Reviewing the property condition and any contributing defects (for example, ventilation performance, building fabric issues or thermal bridging)
• Considering likely root causes such as heating patterns, moisture generation and ventilation pathways
• Understanding how occupant habits and property use can influence moisture levels (such as drying clothes indoors, window opening, extractor fan use and heating routines)
• Producing clear findings so landlords and residents understand what action is required
