_______________________
OUTLINE
1. Introduction & Context
Awaab’s Law: new UK regulation forcing landlords to act fast on damp and mould (14-day remediation window).
Legislative intent vs. logistical reality: shortage of trades, high costs, rehousing obligations.
Early prediction: growth of an emergency damp-response industry.
2. Economic & Social Impact
Heavy financial strain on large landlords and housing associations.
Potential rent increases for low-income tenants.
Law criticised as politically reactive and lacking practicality.
3. Tenant Responsibility & Media Bias
Tenant lifestyle factors—indoor clothes-drying, poor ventilation, overcrowding—often major contributors.
Political correctness discourages open discussion of tenant behaviour.
Media narratives largely demonise landlords and omit technical expertise.
4. Technical Understanding of Condensation
80 % of household mould originates from condensation, not rising damp.
Older, draughty houses rarely mouldy because they allowed moisture escape.
Modern energy-efficient homes trap humidity.
Double glazing removes visible window condensation but shifts moisture to colder wall areas.
5. Solutions & Practical Advice
Mechanical dehumidifiers are the only reliable fix.
Landlords may supply them, but tenants often resist due to running costs.
Education and cooperation are crucial for lasting results.
_______________________
Key Takeaways
• Awaab’s Law is well-intentioned but impractical; it risks pushing costs and rents higher.
• Condensation, not leaks or rising damp, is the main cause of mould in modern homes.
• Tenant lifestyle and ventilation habits are central to the problem but rarely discussed.
• Media and policy focus on blame rather than building physics and shared responsibility.
• Mechanical ventilation or dehumidification is essential to manage humidity.
• Real solutions require cooperation between landlords, tenants, and government policy.

![The Damp Proofing Mistake That Makes Old Houses Worse
Damp in an old house is almost never one problem. Roger Bisby walks through a 1900s renovation near Nottingham to work out where it is really coming from.
The short answer is that most of the moisture here is coming up from the ground rather than in through the walls. There is no damp-proof membrane under the floors, the clay subsoil is holding water even after weeks of heat, and hard sand and cement render is trapping whatever does get in. The cure is ventilation, a proper membrane lapped up the wall, and belt-and-braces damp-proofing rather than tearing out a damp-proof course that is still doing its job.
AJ went to auction on this place, watched it fail to sell, and bought a house that had stood empty for years. He is turning it into a multigenerational home for himself, his wife and his parents, with the old garage block becoming a self-contained side for mum and dad. Stripping out the ground floor turned up rotten skirtings, crumbling fireplace surrounds and a mystery black coating on one of the floors that turns out to be a piece of local building history.

KEY TAKEAWAYS
• Dry rot draws moisture in from elsewhere with its roots, so cutting out the localised damage is not enough, whereas wet rot dies once you take the water away.
• If a house has an original slate or bitumen damp proof course, leave it alone. Drilling into it destroys it, so go above it or below it if you want to add chemical rods.
• Air bricks at the front only give you ventilation at the front. Without a matching route out the back you get no through flow under a suspended floor, and moisture just sits there.
• Clay subsoil holds water all year, which is why a floor with no damp proof membrane can still be visibly wet after a long dry spell.
• Strong sand and cement render with waterproofer in it does not solve damp, it just moves the problem into the wall and pushes the moisture somewhere else.
• Coal tar was used extensively as a damp-proof course and membrane material, and near an old colliery it is exactly what local builders would have had to hand.
• If you are fitting retrofit underfloor heating, get the drawings from the manufacturer and follow them to the letter. Ignoring them is where these jobs go wrong.
