Norfolk based · site-based · working nationwide
Surveying you can
actually check.
30 years of land and engineering surveying, run end to end by the surveyor who signs the deliverable — you get the real data, not just a drawing. Millimetre control on OSGB36, point clouds in your own format, and an answer when you call.

Every survey we do
30 years of practice across 19 service lines. Each one is delivered with the underlying data, not a PDF alone.
Land & Engineering

Engineering Surveys & Setting-Out
Precision setting-out, control and dimensional checks on site.
Construction Progress Monitoring
Regular site measurement tracking progress, volumes and change.
As-Built & Completion Surveys
Final measured records for handover and compliance sign-off.
Aerial & 3D Data

Why people call us
01
Signed by the surveyor who did the work
Whoever attends your site interprets the data and signs the deliverable. No handover, no detail lost in translation, no account manager relaying it.
02
You get the data, not just a drawing
Point clouds, mesh models and raw control issued in your own software. Nothing locked in.
03
Millimetre control, properly proven
OSGB36 National Grid coordinates and OS-level control, so your figures close to the millimetre.
04
Insured, compliant, accountable
Professional indemnity cover held for all of our work, including aerial and 3D data capture, with separate dedicated drone insurance on top. Full CAA compliance on every flight.
05
Flown where the airspace is awkward
Aerial work in London controlled airspace is routine for us, and the authorisations are secured in advance of the flight rather than chased on the day.
Nobody else shows you this
Load the actual point cloud. Fly to any scan.
Most surveyors send you a screenshot. We publish an interactive 3D viewer running on billions of points — click a scan position and the camera flies to exactly where that pass was flown. You can check the work before you accept it.
Open the viewerAccuracy, stated plainly
Millimetres, not adjectives.
Control is delivered on OSGB36 National Grid eastings and northings, with orthometric heights. Every point is traceable to a coordinate reference, which is why your setting-out closes first time and your as-built records actually match the design.

Where we work
Norfolk based, working nationwide. Site-based, so distance is rarely the constraint.
We are based in Norfolk and work right across the South East, East Anglia and the Midlands. 170 towns, districts and boroughs, listed in full rather than described vaguely.
What clients say
“Boundary dispute that had been dragging on for two years and had cost us more in legal fees than the survey itself. Richard was clear, impartial and thorough. The report held up.”
Nick Twomey
Property owner, Kent
“Setting-out accuracy on a commercial fit-out. Not a single peg out. He turned up when he said he would and left the site cleaner than he found it.”
Mitchell Harris
Site manager, Medway
“We needed measured drawings of a Victorian terrace before we could even get planning. Delivered on time, and the point cloud meant the architect could test the loft conversion immediately.”
Julia Cloe
Architect, South East London
