There's water on your land that should be leaving through a pipe someone built a century ago. Nobody knows where the pipe is. The council has no record, the ditch hasn't been touched in years, and every conversation about whose job it is goes nowhere. We tell you where the pipe is. The rest of the argument gets a lot shorter.
No site visit. No three-week lead time. No payment before you've seen it with your own eyes.
England has been laser-scanned from the air to centimetre accuracy, and the survey is public. We build an elevation profile of your road or boundary from it and trace every path water can take across the ground. A culvert exists because water has to cross somewhere, and on most sites the terrain allows exactly one somewhere. Then we go through years of street-level and aerial imagery at that point, which usually shows the structure itself: a headwall in the undergrowth, an inspection cover in the road edge.
Road or field, nearest postcode, what the water does and when. Photos help.
Terrain modelling, flow tracing, imagery checks. Findings usually inside two working days.
Grid reference, what3words square, annotated map. If the structure is there, our invoice stands. If it isn't, reply and we cancel it. No questions.
What this is and isn't: this is a screening study from terrain data and imagery, not a site survey. We guarantee the location of the structure, not its internal condition, and not that clearing it resolves the flooding on its own. Findings are presented as evidence for you and the relevant authorities; we identify what the geometry indicates, and the legal position is for you and your advisers to conclude.
You are not paying us to look. You are paying us for a structure you have seen with your own eyes.
If a check on the ground finds no drainage structure within 25 metres of the grid reference we give you, reply to the invoice within its fourteen-day term and we cancel it in full. We put the grid reference in writing before you pay a penny, and the invoice has fourteen-day terms, so there's time to go and look.
Under the riparian ownership framework, the landowners a watercourse crosses are generally expected to keep it flowing, including culverted sections, and whether or not anyone recorded where they run. Councils' flood-asset registers only have to include structures they consider significant, so small crossings routinely appear on no register at all. When flooding starts, the argument about whose problem it is can run for years, with everyone agreeing the water shouldn't be there and nobody agreeing where the pipe is. A grid reference ends the geographic half of the argument. What's left is a maintenance job.

The road, the nearest postcode, what the water does. That's enough to start.
