The name on a planning application is frequently not the name on the deeds, and the difference decides who you should be talking to. An agent applies, a developer builds, and somebody else owns the land and will still own it in ten years.
Ownership is largely public in England and Wales, most of it is free to look at, and the paid parts cost less than the time people spend guessing.
Start with the free layer
The property search on GOV.UK gives you a free summary for a registered address. That will not name the owner, and it will confirm the property exists as a registered title, which is the first thing worth knowing because not all land is registered.
HM Land Registry price paid data provides recorded sale information within its published scope, with exclusions. A recent transaction can be a reason to research a property, but it does not establish that building work is planned.
Then the planning register for the same address, which tells you what has been applied for and by whom. Read the applicant and the agent as two different facts. The agent is a professional you can build a relationship with across many sites. The applicant may be the owner, a developer with an option, or a tenant.
What the title register actually costs
A title register or a title plan is £7 to download. Official copies, the ones that serve as legal proof of ownership, are £11 each by post. The downloadable version is for information rather than for a transaction, which for commercial research is exactly what you need.
For seven pounds the register tells you the title number, who owns the property, what was paid and when, whether there is a mortgage or other charge over it, and what restrictive covenants and easements apply. The title plan shows the general boundaries.
Put a small budget against this rather than treating each one as a decision. Twenty titles is a hundred and forty pounds and it will tell you more about a patch than a year of driving past it.
Reading a register as a supplier rather than a solicitor
Four things on it change what you do next.
The proprietor. If it is a company, you now have a name to look up on Companies House, and from there its accounts, its officers and its other filings. A property held by a company that owns fifteen others is a portfolio conversation rather than a single job.
The price and date. A property bought recently at a price well above its previous sale usually means somebody has a plan for it, and plans cost money to execute.
A registered charge may identify a lender and the secured property. Check the document before assuming the borrowing is development finance or that work will follow.
The covenants and easements. These decide what can be done on the site, and they are the reason schemes that look obvious never happen. A restrictive covenant limiting use, or an easement giving somebody else a right of way across the access you would need, is worth knowing before you price anything.
The Companies House shortcut
Where the owner is a company you can often skip the fee entirely.
A charge registered at Companies House lists the property charged, so the company's own filing history frequently names the addresses it has borrowed against. That is free, it is searchable by company, and it gives you the lender and the date without going near a title.
It works in the other direction too. If you know a developer is active in your area, read their charges rather than their website. The website says what they would like to be doing. The charges say what they have financed.
Commercial property has its own free register
For anything non-domestic, the rating list is the source people forget.
The rating list helps you research non-domestic properties within its scope. Descriptions and rateable values can provide context, but should not be treated as a complete list of all property or a precise measure of floor area.
Used alongside the planning register it becomes a working territory map. The rating list tells you what exists. Planning tells you what is changing. Ownership tells you who to ring.
Freehold, leasehold, and who actually pays you
This is where suppliers waste the most time, and it is a two-minute check.
On a leasehold commercial property there are at least three parties and they buy different things. The freeholder cares about the structure, the roof and the long-term value. The leaseholder or occupier cares about fit-out, services and anything that affects trading this year. A managing agent sits between them and frequently holds the budget for common parts.
Which one you approach depends entirely on what you sell. Getting it wrong is not a small error, because the freeholder has no interest in the tenant's fit-out and the tenant cannot authorise work to the structure. The title register will tell you whether the title is freehold or leasehold, and a leasehold title names the landlord.
You cannot search it backwards, and that is the real limit
The register answers who owns this address. It does not answer what does this company own, which is usually the more valuable question, and there is no public reverse search.
There is a dataset that goes some of the way. HM Land Registry publishes the commercial and corporate ownership data, which lists registered land and property in England and Wales held by UK companies and other corporate bodies. It is updated monthly, on the second working day. It deliberately excludes private individuals, overseas companies and charities, and it carries the usual warnings about spelling variants, incomplete postcodes and wrong registration numbers, because the entries came from many sources over many years.
The thing to check before building anything on it is the licence. Access needs an account and agreement to a data licence, and the terms decide what you may do with the data commercially. If your intended use is anything beyond looking something up, read the licence properly or ask, rather than assuming that published means unrestricted.
Where the licence is a problem, the Companies House charges route above remains the free answer and it works company by company, which for a supplier working a territory is usually enough.
The restrictions that show a developer moved years ago
One entry on a title is worth more than the rest to anybody watching for early work, and most people skim past it.
When a developer ties up land without buying it, the agreement usually leaves a mark on the register. An option or a conditional contract is commonly protected by a restriction or a notice, which means the register shows that somebody has an interest in the land even though the proprietor has not changed.
A notice or restriction can reveal an interest in land that deserves investigation. It does not establish that a housing scheme will be proposed or built.
It is not a certainty. Options lapse, conditions fail and land gets sold on. What it gives you is a very early, very cheap signal on the sites that matter most, which is exactly where a seven pound title pays for itself.
Identify the professional team
A last point that changes how you use all of this.
A professional team may work on further projects in your area. Where their role is relevant to your product, a useful relationship can extend beyond the first site you researched.
Use ownership research to identify the parties and investigate their roles. The title alone cannot establish whether a scheme is financed or likely to proceed.
Suppliers who do this well end up with twenty consultants who know what they make, rather than a list of two hundred landowners who will never call again.
Where the record runs out
Two limits are worth stating, because both catch people.
Not all land is registered. Registration became compulsory on sale progressively over decades, so land that has not changed hands in a long time, and a good deal of institutional, church and agricultural land, may have no title at all. An absent title is not evidence that nobody owns it.
And a company name is not always the end of the trail. Property held through an overseas entity, a trust or a special purpose vehicle takes you to a corporate name rather than to a person. The register of overseas entities has improved that considerably for foreign-owned property, and it has not made every chain short.
A method that fits in an hour
Take the last three months of planning approvals in your area, filtered to the type of work you do.
For each one, note the applicant and agent. Look up a company applicant and read any relevant charge documents. They can identify secured property, but not the company's entire portfolio. Where ownership matters, check the title register.
Then contact the agent as well as the applicant, because the agent will be on the next scheme too and the applicant may not.
Keep a record of the ownership evidence and the questions it leaves open. Confirm who controls the relevant buying decision before preparing a detailed proposal.
