What’s at stake
The rental sector has changed. New laws. Higher stakes.
Councils have always had the power to issue formal Improvement Notices. Until recently, most chose the informal route — a conversation, a hazard awareness notice, guidance to make improvements. That is shifting.
Pressure is coming from tenants, claims management companies and councils to provide better evidence that rental properties are healthy places to live – and it is landing on landlords and lettings agents.
Opinions and photographs are not enough anymore.
What we have been doing to help
For the last two years we have been working directly with progressive council enforcement teams and landlords, using environmental data to help resolve hazards before a formal Improvement Notice.
Our data has identified root causes and given landlords a clear remediation plan before escalation.
Understanding the problem and acting on it puts landlords tenants and lettings agents in a fundamentally better position.
What we measure
We tell you how the home performs, where the risks are and what to improve first.
Natural ventilation
Is there enough air movement to keep moisture levels down? What could be achieved with an improvement?
Heating performance and habits
Is there enough heat in the right places at the right times? What level would be ideal for the home?
Cost of heating
Is the home too hard and too costly to heat? Often this is part of the mould and damp problem.
Mechanical ventilation
How much moisture is removed during showers and cooking? Are the fans effective and what is the impact of poor performance?
Moisture sources
Where is moisture coming from – inside, outside, specific rooms?
Dehumidifiers
Do you need them or could adjustments to heating and ventilation work better?
Wall insulation
Are walls a cold bridge and what is the ideal indoor temperature and humidity to prevent condensation?
HHSRS risk indicators
Underheating, overheating, damp and mould duration and severity.

– Building Inspection
Find the issue in days rather than months.
"When we get complaints we have to respond quickly. We used to wait 2 months to have monitoring systems put in place. Now we can do it the next day and find the issue in days rather than months."
– Surveyor, Housing Association in the South West of England
For a letting agent, this is a good quick win.
“We had a complaint about mould in a communal hallway. The tenant was blaming the air conditioning units from the shops below. The landlord was blaming the tenant. When we got the report, we could see that the hallway just needed heating. For a letting agent, this is a good quick win."
