Is there a map of unregistered land in England and Wales?
Is there a map of unregistered land in England and Wales? Yes, a few. Here's an honest comparison of the free and paid options, what each one is really for, and which to use.
Yes. There are a few, and they're not the same. Some are free, some are paid. Some are built for researchers, some for people chasing an adverse possession claim, some for property developers, and one (ours) for the simple curiosity of finding the gaps. They draw on overlapping data but answer different questions, so the right one depends on what you're actually trying to do.
Here's an honest run through the maps of unregistered land in England and Wales, including the ones that compete with us, and what each is genuinely good for.
First, what "a map of unregistered land" even means
There is no single official dataset that says "this parcel is unregistered." Nobody publishes the gaps directly. What exists is the opposite: HM Land Registry publishes the INSPIRE Index Polygons, the boundary of every registered freehold in England and Wales, free under the Open Government Licence.
Unregistered land is what's left when you take those polygons away. The blank space. So every "map of unregistered land" is really a map of registered land, with the gaps made visible. The differences between the tools below come down to how they present those gaps, what they add on top, and who they're for.
One caveat that applies to all of them: a gap is a starting point, not a verdict. It might be genuinely unregistered land. It might be a parcel that's registered but didn't make it cleanly into the dataset. The map tells you where to look, not what you've found.
The options, compared
| Tool | Cost | Built for | Shows ownership? | Best for |
|---|---|---|---|---|
| HM Land Registry (INSPIRE / MapSearch) | Free | The official record | No (names cost £7) | The source of truth, if you can handle raw data |
| Who Owns England | Free | Land transparency / research | Some ownership layers | Understanding who owns Britain at a national scale |
| MapMyLot | Free | Quick Land Registry viewing | No | A fast, no-login look at registered boundaries |
| Unclaimed Land | Paid | Adverse possession claims | No | People actively pursuing a claim |
| Nimbus Maps | Paid (pro) | Property developers / agents | Some | Commercial site-finding, deep data |
| Edgelands | £5/mo, 7-day trial | Curiosity / hobby research | No (gaps, not names) | Finding and exploring the gaps, simply |
(Pricing and exact features move around, so treat the table as a guide and check each site for the current detail.)
HM Land Registry, the raw source
The official data, straight from the registry. You can use MapSearch to look up registered titles on a map, or download the INSPIRE polygons and process them yourself.
It's free and authoritative. It's also raw: MapSearch is built around looking up a known property, not browsing for gaps, and the INSPIRE download is heavy GML files that need GIS software to open. Brilliant if you're technical and patient. Hard work if you just want to pan around and look.
Who Owns England
The work of Guy Shrubsole and Anna Powell-Smith, Who Owns England is the reference project on land ownership transparency in this country. Its map layers and the research behind them are widely cited, and the framing of unregistered land as "the holes in the map" largely comes from here.
It's free, it's serious, and it's the best place to understand land ownership at a national, structural level: who owns Britain and why. It's less about helping an individual find one specific gap behind their house, and more about the bigger picture. If you care about the subject, read it regardless.
MapMyLot
MapMyLot is a free, no-account viewer that puts Land Registry boundaries on a map you can browse. Its strength is exactly that friction-free quality: no sign-up, just look. For a quick check of what's registered around a spot, it's genuinely handy.
Unclaimed Land
Unclaimed Land is the most explicitly claim-focused tool in the space. It positions itself around adverse possession: finding land you might be able to claim. It's a paid service.
Here's where we differ on principle, and it matters. We don't sell Edgelands as a way to claim anything, because most unregistered land has an owner and adverse possession almost always fails. If your goal is specifically to pursue a claim, Unclaimed Land is built for that intent and you should look at it. Just go in with the honest odds, which we lay out in unregistered does not mean unowned and adverse possession and the 12-year rule.
Nimbus Maps
Nimbus Maps is a professional property platform aimed at developers, agents, and surveyors. It layers ownership, planning, and site data for commercial site-finding, and it's priced for businesses, not hobbyists. Powerful and expensive. Overkill if you're just curious, the right call if you do this for a living.
Where Edgelands sits
Edgelands maps every registered freehold in England and Wales and leaves the gaps showing, on a map you pan around like any other. We did the download-convert-tile work on the INSPIRE data so you don't have to touch GIS software. Spot a patch with no polygon over it, and you've found something worth looking into. £5 a month, 7-day free trial.
What we're for is the curiosity: the quiet pleasure of finding a forgotten scrap of Britain and wondering about it. What we're not is a claims service. Edgelands shows you where the gaps are, which is the genuinely hard part to do yourself. It doesn't tell you who owns a parcel (that's a £7 title register from HM Land Registry), and it can't help you claim anything. Once you've found a gap that interests you, the next step is a solicitor who does property work, and worth asking early rather than late.
So if you want the national picture of who owns Britain, read Who Owns England. If you're set on pursuing a claim, look at Unclaimed Land with clear eyes. If you do property for a living, Nimbus. If you want the official raw data and you're technical, go straight to HM Land Registry. And if you just want to find the gaps and have a poke around, that's the thing we built.
FAQ
Is there a free map of unregistered land in England and Wales? Sort of. There's no dataset of unregistered land directly, but the free HM Land Registry INSPIRE polygons map all the registered freeholds, and the gaps are the unregistered candidates. Who Owns England and MapMyLot present registered-land maps for free; processing INSPIRE yourself is free but technical.
What's the best map of unregistered land? It depends on the job. Who Owns England for national research, HM Land Registry for the raw official source, Unclaimed Land if you're pursuing a claim, Nimbus for commercial property work, and Edgelands for browsing the gaps simply. They answer different questions.
Does any map show who owns unregistered land? No. By definition, unregistered land has no owner on the public register, so no map can show it. For registered land, the owner is in the title register, £7 from HM Land Registry.
Is unregistered land free to claim? Almost never. Most of it has an owner who simply never registered it. See unregistered does not mean unowned.
Why isn't there one official map of unregistered land? Because the registry maps what is registered, not what isn't. Unregistered land is defined by absence, so every map of it is really a map of registered land with the gaps left showing.
