How it works

From enquiry to usable data

STEP 01
Scope & quote

Tell us the site and the outputs you need. We confirm scope and price — free, no obligation.
STEP 02
Plan & permissions

Flight planning, site liaison, risk assessments and any airspace permissions handled by us.
STEP 03
Fly & capture

Our own pilots capture the site — typically in a fraction of the time ground methods need.
STEP 04
Process & deliver

Data processed into the plans, models and reports your team can use straight away.

Deliverables

What you actually receive

Track record

Trusted on the UK's biggest sites

On HS2: 6+ years; greenfield surveys to viaduct completion
Largest survey: 1,200 ha; believed the UK's largest by drone
Operating since: 2014; owned and run by its two directors
One campaign: 144 roofs; inspected in Central London in 2 months

"The outputs provided from the survey exceeded our expectations with a significant level of detail and accuracy."
