Why Mould Remediation Training Matters More Than Ever in the UK
With Awaab's Law now in force and millions of households affected by damp and mould, the question of who is actually qualified to deal with the problem has never been more important.
With Awaab's Law now in force and millions of households affected by damp and mould, the question of who is actually qualified to deal with the problem has never been more important.
For years, mould remediation in the UK has operated without a dedicated national standard. Unlike gas work, which requires Gas Safe registration, or electrical work covered by Part P of the Building Regulations, there is no legal requirement for someone carrying out mould removal to hold any specific qualification. Anyone can call themselves a mould specialist.
That is a problem, and it is one that affects the people living in affected properties most of all.
The Scale of the Issue
According to the Ministry of Housing, Communities and Local Government (MHCLG), up to 6.5 million households in England are affected by damp and mould. A 2025 report from Health Equals found that 28% of UK adults report living in homes with damp, mould, or cold conditions. The Housing Ombudsman received over 16,000 damp and mould complaints between 2019 and 2024, with the issue now representing around half of its casework.
The tragic death of two-year-old Awaab Ishak in Rochdale, caused by prolonged exposure to mould in his family's housing association flat, brought this crisis into sharp public focus. The resulting legislation, Awaab's Law, came into force in October 2025 and now requires social housing landlords to investigate significant damp and mould within 10 working days, provide a written summary within 3 working days of the investigation ending, and begin making the property safe within 5 working days where a significant hazard is found.
Why Training Matters
Awaab's Law has rightly placed obligations on landlords to act quickly. But speed without competence can make things worse. Mould remediation is not the same as cleaning. Disturbing mould without proper containment can spread spores throughout a property. Using the wrong chemicals in occupied spaces poses its own health risks. Without an understanding of moisture dynamics and building science, treating the visible mould without addressing the underlying cause means it will simply come back.
This is where professional training comes in. The international benchmark for mould remediation is the IICRC S520 Standard, published by the Institute of Inspection, Cleaning and Restoration Certification. The S520 covers everything from risk assessment and containment to air quality monitoring and clearance testing. It is widely used in the United States, Canada, and Australia, and is increasingly referenced in the UK as the sector matures.
Training programmes aligned with the S520 typically cover the science of mould growth, health risks (mould is classified as a Hazard Group 2 biological agent in the UK), safe removal techniques, containment procedures, personal protective equipment, and the importance of identifying and resolving the moisture source.
What to Look for in a Trained Specialist
For homeowners, tenants, housing officers, and property managers trying to find someone competent to deal with a mould problem, there are a few things worth checking:
- Does the contractor hold a recognised mould remediation qualification? CPD-certified training from an established provider is a good starting point.
- Is their training aligned with the IICRC S520 standard?
- Can they explain their approach, including containment, PPE, and moisture assessment, before starting work?
- Do they carry appropriate insurance for remediation work?
- Are they listed in a professional directory where their credentials can be verified?
It is worth being cautious of anyone who offers to "just clean the mould off" without discussing the cause, or who cannot explain what containment measures they would use. Mould remediation done badly can be worse than no remediation at all, as it gives a false sense of security while potentially spreading contamination.
The Training Landscape in the UK
Several organisations now offer mould remediation training in the UK. Courses range from half-day awareness sessions aimed at housing officers and landlords, through to multi-day practical courses covering advanced remediation techniques.
The UK Academy of Mould Experts (UKAME) is one provider that has structured its training around a tiered certification model. Their courses range from a free introductory mould awareness module through to a two-day advanced course covering containment design, air quality management, and remediation planning. Their training content is aligned with the IICRC S520 standard, and they also offer the IICRC WRT (Water Restoration Technician) certification, which is an internationally recognised credential.
UKAME also maintains a directory of certified professionals that housing providers and members of the public can use to verify a contractor's training status, an approach that mirrors the verification model used by Gas Safe and other regulated trades.
Closing the Skills Gap
The introduction of Awaab's Law has created a genuine need for trained, competent mould remediation professionals across the UK. Housing associations, local authorities, and private landlords all need to be able to demonstrate that the contractors they use are properly qualified.
At the same time, remediation contractors and cleaning companies have a real commercial incentive to upskill. As awareness grows among tenants, housing officers, and property managers, the ability to demonstrate formal training and certification is becoming a competitive differentiator.
The UK still lacks a dedicated national standard for mould remediation. Until one exists, training programmes aligned with international standards like the IICRC S520 represent the best available benchmark. For anyone affected by mould, asking about a contractor's training and qualifications before work begins is one of the most practical steps you can take to protect your home and your health.
