Buying land in the UK: a due-diligence checklist

Land rarely comes with the protections buyers expect from a house purchase. Before you commit, work through these checks — they catch the problems that are expensive or impossible to fix after completion.

Whether you're buying a building plot, a paddock, woodland or amenity land, the principle is the same: the price reflects what the seller tells you, but the value depends on what you can actually do with it. A plot with no lawful access, a restrictive covenant, or land that floods is worth a fraction of one without those problems. The checks below are roughly the order a careful buyer should follow.

1. Confirm the legal boundaries and title

Order the title register and title plan from HM Land Registry for a few pounds. Check that the seller is the registered proprietor, that the plan matches what you're being shown on the ground, and that there are no restrictions, charges or notices you don't understand. The red line on a Land Registry plan is indicative, not exact — if precise boundaries matter, walk them with the seller and note any fences, hedges or walls that don't line up.

2. Check the planning history and what's allowed

A plot advertised as having "development potential" may have none. Search your local planning authority's portal for the site's planning history, and look for whether any permission or permitted-development rights actually exist. Refused applications and enforcement notices tell you a lot. If your plan depends on permission you don't yet hold, treat the purchase as speculative and price it accordingly.

3. Establish access, rights of way and easements

Land without a legal right of access to a public highway can be effectively unusable. Confirm how you'll lawfully reach the plot, and whether services (water, drainage, electricity) can be brought to it. Check for easements and wayleaves crossing the land — pipes, cables and others' rights of way — that could limit where you build.

4. Assess ground and environmental risk

Three risks routinely surprise buyers: flooding, ground movement and contamination. Check the Environment Agency's flood-risk maps for the postcode, consider whether the area is prone to subsidence (clay soils, former mining, nearby trees), and ask whether previous use could have left the ground contaminated. A clean-looking field can sit on a flood plain or shrinking clay.

5. Look at what's been happening on and around the plot

The land's recent history is often the most telling signal of all. Has the ground been disturbed? Is there construction or a large planning application next door that will affect access, outlook or value? Are there signs of unauthorised use or encroachment from a neighbour? Satellite imagery and local planning data let you build this picture before you ever visit — and keep watching after you buy.

6. Before you exchange

Instruct a conveyancing solicitor to run the standard searches and review the title properly. Re-read everything: the title register, the search results, any covenants, and the seller's replies to enquiries. If anything is unclear, get it answered in writing before you exchange contracts — your leverage disappears the moment you do.
