Due Diligence Checklist
Buying or developing UK land involves checking title, planning status and environmental risk before you commit. Use this as a starting point for any site — then confirm specifics with the relevant local authority, HM Land Registry, or a qualified professional.
| # | Check | Why It Matters |
|---|---|---|
| 1 | Confirm the title number and registered proprietor | Establishes legal ownership before any offer or agreement, and flags whether the title is even registered at all. |
| 2 | Review the title plan against physical boundary features | Title plans show general, not precise, legal boundaries — a mismatch with fences or walls can signal a future dispute. |
| 3 | Check for Green Belt, Conservation Area or Listed Building status | Determines what changes are realistically possible, and whether extra consents are needed alongside planning permission. |
| 4 | Check the flood zone and surface water flood risk | Affects insurability, design requirements (e.g. raised floor levels) and long-term value. |
| 5 | Check for Tree Preservation Orders or ancient woodland | Restricts felling and can affect site layout, access and the cost of any groundworks nearby. |
| 6 | Check for Article 4 Directions | Removes permitted development rights that would otherwise let some works proceed without an application. |
| 7 | Review relevant Local Plan allocations and saved policies | Indicates the type and scale of development the authority expects, and what's likely to be resisted. |
| 8 | Check for restrictive covenants, easements or rights of way | Can limit use or require third-party consent for development, sometimes indefinitely. |
| 9 | Confirm legal access rights and public rights of way | Confirms the site can actually be used and reached as intended, and whether any footpath crosses it. |
| 10 | Check for coal mining risk, contaminated land or radon risk | Affects ground conditions, insurance, construction cost and, in some cases, mortgageability. |
Why Each Check Matters
Title and boundary checks protect against disputes after purchase — a fence in the wrong place can turn into years of dispute if not caught early. Planning designation checks (Green Belt, Conservation Areas, Listed Buildings) determine what changes are realistically possible, often before a single design cost is incurred. Flood risk and environmental checks affect both insurability and long-term value, and are increasingly scrutinised by mortgage lenders. Access and rights-of-way checks confirm the site can actually be used and reached as intended — a site with no legal access is effectively undevelopable regardless of its planning status.

Frequently Asked Questions
Is a due diligence checklist a substitute for a solicitor?
No. A checklist like this helps you ask the right questions early and avoid an obvious oversight, but a solicitor or conveyancer should still handle the legal transaction, and a surveyor should inspect the physical condition of any property.
How long does full due diligence typically take?
For a straightforward residential purchase, conveyancing searches typically take two to six weeks. For a development site, desktop due diligence on constraints can be completed in under a day using mapping tools, though formal surveys and legal searches still take longer.
What is the single most commonly missed check?
Article 4 Directions and unregistered restrictive covenants are the two checks most often missed by inexperienced buyers, since neither always shows up in a standard set of conveyancing searches without being specifically requested.
