Ventilation MOT

A Survey to Grade Property Ventilation

Cornerstone recognise the majority of reported damp, condensation and mould issues relate significantly to the control of atmospheric moisture in a dwelling.

With an array of ventilation solutions available both background and forced mechanical measures, it is important to understand the impact each has on the building and the occupants.

Similarly, the location of ventilation devices is crucial in securing its optimum effectiveness and adherence to existing Building Regulations.

The Ventilation MOT® measures and establishes a compliance Grade based upon predefined algorithmic solutions aligned to:

  • Occupancy level
  • Structure geographical location and orientation
  • System performance
  • System management and utilisation
  • Background ventilation, performance and use

Our Property MOT’s Available.


The PropertyMOT® survey consists of an array of unique services which revolutionise your property management by completing a non-invasive assessment.

Moisture MOT

The Moisture MOT® solution embraces proven knowledge and understanding of moisture in buildings pertaining to the accurate determination of current atmospheric conditions.

Property Analysis Model

The Ventilation MOT® embraces industry recognised data/parameters to carry out an analysis of the property including Geographical location and UK Mean Temperature data from the Met Office in order to align its UK site to the expected construction behaviour.

A pre-set defined surveying process serves to acquire credible fact-based data through all areas of a property with an interactive acknowledgement of existing and potential conditions.

Algorithms within the Ventilation MOT® align to recognised British Standards including BS 5250:2002 Code of Practice for Control of Condensation in Buildings. Annex B – Moisture generation and ventilation in occupied buildings.

A unique component of the Ventilation MOT® is the ability to undertake accredited training with the Property Health Alliance to secure a certified CMOTS qualification enabling interested surveyors to undertake the Ventilation MOT® surveys. All data submitted by an accredited surveyor is analysed by the receiving SMART Portal with certificates and applicable advisories issued back to the surveyor for distribution to their clients.
