Ocuair ® are drone survey, aerial survey and inspection, building survey and data acquisition specialists. We work nationwide with Surveyors, Portfolio Owners, Facilities Managers and others with a professional interest in the built space.

Drone surveys

Key to our success are our aerial drone surveys which can position a wide range of sensors to acquire data from a unique perspective.
Along with data we gather by other means, we aim to provide the right information to our clients to allow hard decisions to be made easily.
We are number 650 on the CAA register of drone operators.


Providing and improving our service means we are constantly innovating in a fast moving technological environment. Our experience understanding, quantifying and recommending solutions to problems has been gained over 8 years. We were the first to fly a drone across the English Channel. We have led the field in using drones to understand buildings through thermal imaging and are one of the first drone operators to become a RICS Tech Partner.

Risk Assessment and Operating Safety Case

All Ocuair pilots are Qualified A2CofC and GVC. They can operate in the Open or Specific Category under a CAA Pre-Defined Risk Assessment. We are also proud to have achieved our Operating Safety Case which further reduces the distance separation required from uninvolved people, allows operating in congested areas and where applicable, extends visual line of sight out to 1000m.

Our Services


drone building surveyBuilding Defect Surveys

There are 3 aspects to these surveys:

  • Visual
  • Thermal
  • Physical testing


By using our range of drones and cameras and sensors, we will provide a bespoke survey of your building or asset to look for specific defects, or to provide a record enabling an assessment to be made.    Our drone surveys are almost always better value, safer and faster than traditional methods, and are designed to work in conjunction and be complimentary to more conventional survey types.
