Sourcing land with planning potential: Companies House and planning records

This is a sourcing guide, not a deal-structuring guide

Worth being upfront about scope. This piece is entirely about finding land and reading the signals that suggest an owner might be receptive to a conversation. It does not cover how to structure what you offer once you have identified a site, an option agreement, a subject-to-planning purchase, a promotion agreement, each of those is a different commercial structure with different risk profiles, and each deserves its own explanation. For the structuring side, see our guides to subject-to-planning property deals and option agreements explained. This guide stops at the point where you have identified a site and a signal worth acting on.

Why landowning SPVs are worth a closer look

A meaningful share of land with unrealised development potential sits inside single-purpose vehicles, companies set up years or decades ago to hold one plot, sometimes for a project that never happened, sometimes as a long-term family holding. These companies often show a distinctive pattern: minimal trading activity, a small board, and a property asset that has not moved in a long time. That pattern is worth searching for deliberately rather than stumbling into it.

The reason this matters is timing. An active developer with a live project is negotiating from a position of momentum, they have plans, funding, and a timeline. A dormant SPV sitting on land with no active project is not negotiating from anywhere, because nobody inside the company is currently thinking about the asset at all. That is a very different conversation to walk into.

Companies House signals worth checking

Companies House is free to search and gives you most of what you need to assess whether a landowning company looks dormant or active. Specific things worth checking for any company that owns a site of interest:

• Dormant company accounts. A company filing dormant or micro-entity accounts, especially for several years running, is not actively trading, whatever it owns is simply sitting there.
• SIC codes. Codes for buying and selling own real estate, or renting and operating real estate, narrow the search to companies whose business is holding property rather than something unrelated.
• Company age against the land's history. A company incorporated decades ago that still owns the same asset has likely held it through several planning cycles without acting on it.
• Director resignations. A recent resignation, particularly where it leaves a single remaining director, or a board that has shrunk over several years, can signal a company winding down its active involvement, sometimes ahead of a wider decision about what to do with its assets.
• The charges register. A charge that has been satisfied and never replaced can mean a company that once had development finance in place and has since stepped back from an active project. A charge still outstanding tells you a lender has a live interest in what happens to the asset.
• Registered office and accountant changes. Frequent changes can indicate a company being tidied up or wound down; long stability at the same address alongside dormant filings often points the other way, toward simple inactivity rather than change in progress.

Cross-referencing against planning records

Companies House tells you about the owner. Planning records tell you about the site's potential and its history. Both are needed before a signal is worth acting on.

• Local Plan allocations. Most councils publish their adopted or emerging Local Plan online, including maps of sites allocated for housing or employment use. A site sitting inside an allocation, owned by a dormant company, is a very different prospect from an unallocated field.
• Pending and validated applications. Council planning portals are searchable by address or by owner in many cases. A live application on a neighbouring site can indicate the area's development trajectory even where the site itself has none.
• Lapsed permissions. Planning permission that was granted and never implemented, and has since expired, is one of the strongest signals available. It tells you someone once had the intent and the means to develop the site, and for whatever reason, funding, a change in circumstances, a falling out, the project stalled. That history is often visible on the same planning portal entry, since councils typically keep expired applications searchable rather than removing them.
• Pre-application enquiries. Where a council publishes a register of pre-application advice requests, a site that had one several years ago but no follow-up formal application suggests an owner who explored development and did not proceed.

Reading the combination

No single signal above is a strong reason to write to anyone. A dormant company on its own is common and usually meaningless. A lapsed planning permission on its own might just reflect a difficult market at the time. The signal worth acting on is the combination: a dormant SPV, holding a site inside a Local Plan allocation or with a lapsed permission attached, where the company has also seen a recent director resignation or a satisfied charge with nothing replacing it. Each element on its own is weak. Stacked together, they describe an owner who once had intent, no longer has active momentum, and sits on an asset with a real, documented case for development. That is worth a specific, well-researched letter.

A worked example

The Chelmsford land deal shows what the structuring side of this looks like once a site has been identified this way, a subject-to-planning purchase that limited the buyer's upfront risk to planning costs alone, on a plot approached directly rather than found through an agent. This guide is the layer that comes before that story starts, the process of finding a plot like it in the first place.

Where this differs from land banking

None of the above should be confused with the retail land banking model covered in our land banking guide, which is about companies selling small plots of unserviced land to individual retail buyers, often at inflated prices with little realistic prospect of planning consent. This guide is about identifying genuine landowners and genuine sites with a documented planning case, the opposite end of the market from that model.

Where this differs from general distressed-owner sourcing

Our guide to finding distressed property owners covers the general public-record landscape, Companies House, the Insolvency Register, the Gazette, court records, across property types generally. This guide goes deeper on one specific, land-focused slice of that landscape: the combination of company status and planning history that applies specifically to undeveloped or under-developed land, rather than the wider set of signals relevant to residential and commercial property generally.

The bottom line

Land with planning potential is not scarce. Land with planning potential owned by someone who might actually engage with you is much rarer, and finding it means reading Companies House and planning records together rather than either in isolation. A dormant company alone, or a lapsed permission alone, is a starting point. The combination of several such signals on the same site and the same owner is what turns a search into a lead worth a letter.

Common questions

What is a landowning SPV?

A single-purpose vehicle set up to hold one property or site, often a piece of land, rather than to trade actively. They are common in UK land ownership and searchable on Companies House like any other company.

How do I find planning applications for a specific site?

Most councils run a searchable online planning portal covering current and historic applications for their area. Search by address, or by the site's parish or ward if the exact address is not indexed, and check for both live and expired applications.

What does a lapsed planning permission tell me?

It tells you someone previously had both the intent and, at the time, the means to develop the site, and that the project did not proceed before the permission expired. That history is a strong starting signal, though it does not tell you why the project stalled, which is worth establishing before you approach the owner.

Is this the same as land banking?

No. Land banking, as covered in our separate guide, refers to companies selling small unserviced plots to retail buyers with little realistic development prospect. This guide is about identifying genuine landowners with a real, documented planning case for their site.

This is general information, not legal or planning advice. Local Plan status, planning history, and company records change over time, always confirm current details directly with the relevant council and Companies House before acting.
