Metal Detecting on Common Land in the UK: What You Can Do

Common land is one of those topics that trips up a surprising number of detectorists, even experienced ones. You can see why — the phrase “common land” sounds like it should mean land that belongs to everyone, land that’s open and freely available. In practice, the legal reality is quite different, and getting it wrong can lead to anything from an awkward conversation with a warden to a genuine legal problem. Let’s work through what common land actually is, what the law says, and how you can go about detecting on it properly.

What Is Common Land, Exactly?

Common land in England and Wales is land over which certain people (known as “commoners”) hold specific legal rights — to graze animals, collect wood, fish, and so on. These rights date back centuries and are still legally protected today. The land itself is almost always privately owned, even if it looks wild and open. The owner is typically a private individual, an estate, the National Trust, a local authority, or in some cases the Crown.

In England and Wales, common land is registered under the Commons Registration Act 1965 (now largely superseded by the Commons Act 2006). You can check whether a piece of land is registered common land by searching the Commons Registration Authority for the relevant county or unitary authority. Natural England also maintains a publicly searchable register. In Scotland, the situation differs — there’s no equivalent commons register, and the Land Reform (Scotland) Act 2003 gives much broader access rights, though that doesn’t automatically include metal detecting.

Key examples of common land include village greens, many upland areas such as parts of Dartmoor, the New Forest (which has its own specific legal framework as a National Park), large chunks of the South Downs, common grazing land in Wales, and countless smaller patches throughout England. Some are bustling spots full of dog walkers; others are remote moorland that you could walk for hours without seeing another person.

The Core Legal Position: Access Does Not Mean Permission to Detect

This is the single most important thing to understand. The Countryside and Rights of Way Act 2000 (CRoW Act) gives the public a right of access on foot over registered open access land, which includes most common land. That right covers walking, running, climbing, and similar activities. It does not cover metal detecting.

Section 2(1) of the CRoW Act specifically lists activities that are excluded from the general access right. Metal detecting — or more precisely, using any apparatus for the purpose of searching for or removing any object from the land — is not a permitted activity under the open access provisions. So even if you have the legal right to walk across a common, that right gives you no entitlement whatsoever to swing a coil over it.

To detect on common land legally, you need two things:

• Permission from the landowner (the person or body that owns the land itself)
• Where relevant, consent from any body that has management or statutory responsibility for the land, such as a commons council, Natural England, or a National Park authority

Some common land also has bylaws attached to it that specifically prohibit metal detecting regardless of what any individual landowner might say. Always check for bylaws before you do anything else.

Finding Out Who Owns Common Land

This can be surprisingly tricky. The Land Registry holds title information for most registered land in England and Wales, and you can pay a small fee to search for ownership details online at the HM Land Registry website. Not all common land has a registered title, though, particularly older commons where ownership has never formally been recorded. In those cases, local knowledge, estate agents familiar with the area, or the commons registration authority may be able to help.

For National Trust commons — and the Trust manages an enormous amount of common land across England, Wales and Northern Ireland — the National Trust’s regional offices handle enquiries. The Trust has generally been quite cautious about granting metal detecting permissions on its land, though it is not an absolute blanket refusal. Their position varies by site based on archaeological sensitivity and management considerations.

For local authority-owned commons, your first point of contact is the relevant council’s parks, countryside, or open spaces department. Some councils have formal processes for granting permissions; others deal with requests on an ad hoc basis.

Crown-owned common land, including some managed through the Crown Estate, requires contact with the Crown Estate’s regional teams. Parts of the Duchy of Lancaster and Duchy of Cornwall estates also include common land, each with their own permissions processes.

The Treasure Act 1996 and Your Obligations

Whatever land you’re detecting on — common or otherwise — the Treasure Act 1996 applies throughout England, Wales and Northern Ireland. If you find something that meets the definition of Treasure, you are legally obliged to report it to the local coroner within 14 days of either making the find or identifying it as potential Treasure.

Under the Treasure Act, finds qualifying as Treasure include:

• Any object other than a coin that contains at least 10% gold or silver and is at least 300 years old
• Two or more coins from the same find that are at least 300 years old and contain at least 10% gold or silver
• Ten or more coins from the same find that are at least 300 years old (regardless of metal)
• Any object found in association with items that qualify as Treasure
• Prehistoric base-metal assemblages (added by the Treasure (Designation) Order 2002)

There is currently work underway to update the Treasure Act through the Treasure (Portable Antiquities and Treasure) Bill, which had been progressing through Parliament. This would extend Treasure definitions further, so it’s worth keeping an eye on developments through the Portable Antiquities Scheme (PAS) website.

When Treasure is found, a reward is typically shared between the finder and the landowner in proportions agreed between them. If you’re detecting without the landowner’s permission — on common land or anywhere else — you have no legal entitlement to any reward, and you may also be committing criminal trespass if aggravating factors are present, or at minimum civil trespass.

The Portable Antiquities Scheme and Why It Matters

The Portable Antiquities Scheme (PAS) is a voluntary programme run by the British Museum and Amgueddfa Cymru (National Museum Wales) that encourages finders of archaeological objects to record them with their local Finds Liaison Officer (FLO). The scheme has built up one of the largest archaeological databases in the world, and the data has been used in hundreds of academic studies.

Recording your finds with the PAS costs you nothing, helps build a picture of the archaeological potential of the areas you’re detecting, and is widely regarded as best practice within the responsible detecting community. If you do manage to get permission to detect on common land, recording your non-Treasure finds with your local FLO is exactly the kind of activity that builds goodwill and supports future permissions being granted to other detectorists.

The National Council for Metal Detecting (NCMD) and the Federation of Independent Detectorists (FID) both strongly encourage PAS recording as part of their codes of conduct. Being a member of either organisation and operating under their codes can also strengthen your case when approaching landowners for permission.

Village Greens: A Special Category

Village greens deserve particular attention because they’re often misunderstood. A registered village green is a specific legal category of common land where local inhabitants have a customary right to indulge in sports and pastimes. Many village greens are owned by the parish council or local authority.

Metal detecting on a village green without permission is not just trespass — it can also fall foul of the Commons Act 2006, which makes it an offence to carry out works that have the effect of preventing or impeding access to or over any town or village green. Digging holes, even small ones, on a village green could in principle be considered such an offence. The penalties can include fines and an obligation to restore the land.

This doesn’t mean you can never detect on a village green — it means the bar is considerably higher, and you’d want written permission from the owner, confirmation that there are no bylaws preventing it, and ideally some liaison with the local community and parish council before you start.

Scheduled Monuments: An Absolute No

Some common land contains or overlaps with Scheduled Monuments — sites of national archaeological importance protected under the Ancient Monuments and Archaeological Areas Act 1979. Detecting on a Scheduled Monument without written consent from Historic England (or Cadw in Wales, Historic Environment Scotland in Scotland, or the Historic Environment Division in Northern Ireland) is a criminal offence, full stop. It doesn’t matter what permission the landowner gives you. Scheduled Monument Consent cannot simply be granted by the landowner — it requires formal government approval.

Before detecting on any common land, check the National Heritage List for England (NHLE), Coflein (Wales), Canmore (Scotland), or the Northern Ireland Sites and Monuments Record to see whether the area contains any scheduled sites. These databases are freely searchable online.

Areas of Special Scientific Interest (SSSIs) add another layer of complexity. Many upland commons are designated SSSIs, and digging on a SSSI without Natural England’s consent can result in prosecution. Check the Magic Map application (available on the Natural England website) to identify environmental designations before you make any approach for permission.

Approaching Landowners for Permission: Practical Tips

Once you’ve confirmed who owns the land, checked for bylaws, and established that the site isn’t scheduled or otherwise protected, you can make your approach. A few thoughts on doing this well:

Moving Forward

Once you have the fundamentals in place, the possibilities open up considerably. The UK offers fantastic opportunities for anyone interested in this hobby, and with the right foundation you will be well placed to make the most of them.
