Buying a building plot in or around Haddington? See how the ground falls and what constraints apply before you commit, using the Scottish Government LiDAR flown over the area and published on the Scottish Remote Sensing Portal.
Across the Haddington area (6.86 km² from the OS Open Names extent), open LiDAR covers 100% of the ground. The best survey for most of it is LiDAR for Scotland Phase 3, flown 2015–2019 on a 0.5 m grid (99.7% of the area).
Other parts use LiDAR for Scotland Phase 1, flown 2011–2012 (0.3%). A plot near the join between surveys may draw on both; the report shows which survey covers each part of your boundary.
That survey is about 7 years old. Plots in Haddington that have been cleared, filled or built on since then won't show those changes, so the report flags the date at the top of every page and checks for buildings mapped since the flight where it can.
Most of the ground across the area (96% of readings) lies between 40.8 m and 98.8 m above Ordnance Datum, with a median of 58.8 m. The extremes (38.9 m to 105.5 m) can include water surfaces and data edges, so we don't quote them as ground levels.
Much of Haddington is gently sloping, with steeper banks in places (8.4% over 1 in 10). Two plots a street apart can differ a lot, so the plot-level contours matter more than the town average.
Fitting a plane through the 10 m levels, the ground across Haddington falls generally towards the south-east at about 12.8 m per km (roughly 1 in 78). The lowest tenth of the ground lies mostly to the east, and the highest tenth lies mostly to the north-west.
About 37.7% of the 10 m samples are flatter than 1 in 40, while one in ten is steeper than 5.3°.
On SEPA's flood maps (medium likelihood), 11.9% of the Haddington extent is inside the river flood extent, 7.9% inside the surface water extent and none inside the coastal extent. The extent is a rectangle round the town, so it can take in foreshore, sea and open ground. These are indicative national maps, not a flood risk assessment; a plot report gives the figures for your own boundary.
Historic Environment Scotland has 325 listed building records in the extent (11 category A, 228 category B, 86 category C), and 2 scheduled monuments, 1 conservation area and 2 inventory gardens and designed landscapes overlapping it. A plot report lists any that touch or sit near your boundary.
No NatureScot SSSI, SAC, SPA, Ramsar site or National Nature Reserve overlaps the Haddington extent.
None of the Haddington extent is within the Coal Authority's Development High Risk Area.
Nearest towns with pages here: East Linton, 8.7 km north-east, median ground about 31 m lower; Tranent, 10.7 km west, median ground about 35 m higher; Cockenzie and Port Seton, 10.7 km west, median ground about 50 m lower; North Berwick, 12.2 km north, median ground about 29 m lower.
Sampled every 10 m, the typical slope is 1.9°, and 8.4% of the area is steeper than 1 in 10. A single plot can be much flatter or steeper than this. Its report works at 0.5 m.

Read from the open LiDAR at a 10 m sample on 2026-10-23; local data checked 2026-10-23. A plot report reads the same data at 0.5 m for your boundary only.
Accuracy. We test Scottish LiDAR against independent survey overlaps and Ordnance Survey levelled trig pillars: heights are ±0.14 m typical on open ground (95% within ±0.28 m). Results by survey phase.
