Where can you legally metal detect in the UK? The permission you think you have

Every guide to metal detecting in the UK opens the same way: get the landowner's permission. That is correct, and it is close to the least useful sentence in the hobby, because it implies the hard part is finding someone to ask. It is not. The hard part is that a landowner's yes can be worthless without anyone in the conversation realising it.

The reasons are written down in places a detectorist never looks: a National Trust web page, an agreement with Defra, a schedule to an access statute, a set of byelaws from 1982, a National Park Authority's own advice page. This article works through them in the order that matters and quotes the source sentence for every rule, with the link beneath it. England, Wales, Scotland and Northern Ireland then run on four different legal regimes, so there is a four-nation comparison further down as well.

Does the landowner's permission cover everything?

No. Permission from the landowner is necessary everywhere in the UK, on farmland, on beaches, in council parks and on your own property. It is not sufficient anywhere. Two questions have to be answered every time, and most detectorists only answer the first: who owns this ground and is the person saying yes authorised to say it, and what sits on top of the ground that removes their ability to permit detecting at all.

Is a tenant farmer's permission valid on National Trust land?

Not on its own. A tenant farmer occupies the field, farms it, and reasonably believes it is his to open up. On National Trust land he cannot give you permission.

The Trust states that "we do not grant 'metal detecting licences'", allows detecting only as part of a project "supported by a Research Design", and closes off the ploughed-field argument: no Agreement, no detecting, "even where it's under the plough". Detect without one and "you'll be asked to leave the property and we'll take action to reclaim any finds made on National Trust land".

Can a National Park Authority give you permission?

Not in the New Forest, and the instinct to ask the Authority is a natural one.

The Authority then lists who does own the ground, and the answers disagree. Within one National Park it records that detecting is not allowed on National Trust land without permission, not allowed on Hampshire County Council land without permission, "not permitted on New Forest District Council land", and "not permitted on Wiltshire Council land". It adds that "Most of the New Forest National Park" carries an SSSI designation "and most of the Crown Estate-owned foreshore within the National Park is also designated under separate SSSIs", with permission routed to Natural England. That last clause is the whole article in one line: Crown Estate foreshore is the one place in England, Wales and Northern Ireland that needs no formal consent to detect, and here most of it carries a separate SSSI anyway.

The six overrides that sit on top of a landowner's yes

Once you have a valid yes from the right person, six things can still take it away. None of them is visible from the field gate.

What counts as a protected place?

In England, section 42 of the Ancient Monuments and Archaeological Areas Act 1979 makes it an offence to use a metal detector in a protected place without written consent from Historic England, punishable on summary conviction by a fine not exceeding level 3 on the standard scale. Section 42(3) is the separate offence of removing an object of archaeological or historical interest found there, at the statutory maximum summarily or a fine on indictment. Section 42(2) defines a protected place as the site of a scheduled monument, a monument in the ownership or guardianship of the Secretary of State, the Commission or a local authority under the Act, or a place in an area of archaeological importance (AMAA 1979 s.42).

Two defences run, and neither is owning the land: s.42(6), that the detector was used for a purpose other than detecting objects of archaeological or historical interest, and s.42(7), that you took all reasonable precautions to find out whether the place was protected and did not believe it was. Level 3 is £1,000 in England and Wales under Sentencing Act 2020 s.122(1), and £1,000 in Scotland under Criminal Procedure (Scotland) Act 1995 s.225(2). If a guide sources the standard scale to section 37 of the Criminal Justice Act 1982, that provision was repealed on 1 December 2020.

Is there a 20 metre rule around scheduled monuments?

Not one we could source. No 20 metre buffer appears in section 42 or in its definition of a protected place, which is framed by the site of the monument rather than by a radius. Historic Environment Scotland states the real risk better: "Almost all scheduled monuments are likely to include below-ground archaeology. This often extends further than the visible features. You can check the location and extent of scheduled monuments on the PastMap website." Check the mapped extent rather than pacing out a distance from what you can see.

Does Wales still use a section 42 licence?

No. Since 4 November 2024 Wales runs on section 60 of the Historic Environment (Wales) Act 2023. Section 60(2) makes it an offence to use a metal detector in a protected place without the written consent of the Welsh Ministers, s.60(4) covers removing an object of archaeological or historical interest discovered there, s.60(8) sets a fine not exceeding level 3 for the use offences, and s.60(9) provides for a fine on summary conviction or on indictment for removal. The commencement is dateable: legislation.gov.uk records "S. 60 not in force at Royal Assent, see s. 212(2)" and "S. 60 in force at 4.11.2024 by S.I. 2024/860, art. 3(a)".

Applications go to scheduledmonuments@gov.wales, and Cadw states consent "will not normally be granted for the use of metal detectors unless the survey forms part of a consented archaeological excavation or wider research strategy". If a guide sends you to a section 42 licence for Welsh ground, it has not been updated since 2024.

Does open access land mean open detecting?

Close to the opposite, and this override catches people who have done nothing else wrong. Schedule 2, paragraph 1(k) provides that the right of access under section 2(1):

Paragraph 2(1) defines a metal detector as "any device designed or adapted for detecting or locating any metal or mineral in the ground". The restriction bites on "uses or has with him", so carrying it is enough and you need not switch it on. Section 2(1) grants the right to enter and remain on access land "if and so long as... he observes the general restrictions in Schedule 2", so a detector removes the entitlement itself rather than triggering a separate provision. Section 2(4) then adds a second consequence that is easy to miss: someone who becomes a trespasser this way "may not, within 72 hours after leaving that land, exercise his right under subsection (1) to enter that land again or to enter other land in the same ownership" (CRoW Act 2000 s.2). Guides get this wrong in both directions. Walking onto access land with a detector is not a criminal offence in itself: it cancels your right to be there, which makes you a trespasser, a civil matter unless some other offence applies on top.

Can you metal detect in a Forestry England wood?

Not without written authority, and the reason is a set of byelaws from 1982 rather than anything on the car park sign.

Byelaw 2 defines "lands of the Commissioners" as "lands which are under the management or control of the Commissioners and to which the public have, or may be permitted to have, access", byelaw 3(1) applies byelaw 5 to all of them, and byelaw 3(3) is the route through: "Nothing in these byelaws shall make unlawful anything done with the written authority of the Commissioners." The instrument is also on legislation.gov.uk as S.I. 1982 No. 648. The byelaws as published carry no penalty clause of their own, but they do not need one. The byelaws are made under section 46(1) of the Forestry Act 1967, and section 46(5) of that Act makes breach of a byelaw a summary offence carrying a fine not exceeding level 2 on the standard scale, which is £500 under Sentencing Act 2020 s.122(1). The request goes to the Commissioners rather than to a ranger on the track, and for the New Forest Crown lands the National Park Authority publishes a route: detectors are "not permitted on New Forest Crown land without express permission. Email southern.permissions@forestryengland.uk for more information."

What about Scotland's national forests?

Forestry and Land Scotland publishes a policy, and it also disposes of the commonest Scottish myth, that the right to roam carries detecting with it.

Detecting may be permissible there as part of an archaeological project with a project design agreed in advance, subject to agreed locations and standards, an agreement that the finder waives any right to reward on the National Forest Estate, and agreement on conservation costs. The wider Scottish position is in the Scottish metal detecting rules.

Can a farmer's agreement with Defra override the permission they gave you?

Yes, and this is the layer no competing page assembles. Historic England explains the mechanism: "When land managers enter a legal agreement with Defra for an agri-environment scheme, they sign up to a range of conditions." Those conditions can restrict detecting on parts of the holding, and the restricted parts are named in documents you will never be shown.

Countryside Stewardship has operated since 2016. The older Environmental Stewardship closed to new applicants in 2014 with its last agreements expiring in 2028, and it names the invisible document: under Higher Level Stewardship, "Metal-detecting is not permitted on archaeological sites on holdings with Higher Level Stewardship agreements or Sites of Special Scientific Interest without the permission of Natural England: such sites will be identified in the landowner/farmer occupier's Farm Environment Plan." So ask whether the holding is in either scheme and whether any fields are excluded. Historic England also records that "Natural England requires up to 12 weeks notice of any large scale metal detecting events (known as rallies) on Environmental Stewardship land", and that hobby detecting allowed by Agreement Holders must follow the current Code of Practice for Responsible Metal Detecting, with finds reported to the Portable Antiquities Scheme.

Can a council byelaw stop you on public land?

Yes, and the mechanism is confirmed by an unlikely source. Clause 2 of the Crown Estate's own metal detecting Terms and Conditions, dated 22/01/2024:

There is no national register of which councils permit detecting and no reliable national count, so nobody can tell you what proportion allow it. What you can do is recognise which of four patterns your council falls into. Every authority we verified on 10 September 2026 fits one.

Enforcement comes from the byelaw or the order rather than from heritage law. North East Lincolnshire's is a £100 fixed penalty under the Anti-Social Behaviour, Crime and Policing Act 2014. BCP Council states it does "not allow anyone to use metal detectors in our parks, gardens or nature reserves", and its byelaws page states you can be "fined up to a maximum of £500".

The SSSI override runs straight through these policies, which is the clearest way to see two layers working at once. Cornwall states detecting "is not permitted on beaches which have an SSSI attached to them". Arun needs no permit on its beaches but states that "As West Beach, Littlehampton is a Site of Special Scientific Interest (SSSI) metal detecting is not allowed". Sefton allows it "on the beach in certain areas (seashore bylaw 9b) NOT in the dune system this is a SSSI protected site (sandhill bylaw 11)". The verified sample, each source URL and a repeatable method for checking your own authority are in the guide to councils that allow metal detecting.

Why is Northern Ireland stricter than the rest of the UK?

Because you can commit an offence there without switching anything on, and because a search that disturbs the ground needs a licence rather than a consent.

The same guide quotes the possession offence: "If a person has a detecting device in his possession in a protected place without the written consent of the Department he shall be guilty of an offence and liable on summary conviction to a fine not exceeding level 4 on the standard scale." Article 41 of the Historic Monuments and Archaeological Objects (Northern Ireland) Order 1995 makes it an offence to excavate "in or under any land (whether or not such excavation involves the removal of the surface of the land) for the purpose of searching generally for archaeological objects" except under a licence issued by the Department, at level 3. Article 42 requires anyone who finds an archaeological object to do two things within 14 days: report the circumstances, the nature of the object and the name of the owner or occupier of the land, and, subject to article 42(2), deposit the object itself with a relevant authority. Article 42(7) attaches a level 3 fine to failing to comply with any provision of the article without reasonable cause, so the duty to hand the object over carries the same exposure as the duty to report it.

The four nations compared

There is no single UK set of rules. There are four, and one of them changed in November 2024.

The Scotland column needs a caveat, because the £50,000 gets quoted everywhere without its basis. The figure is real, but it belongs to section 2(10) of AMAA 1979 in its Scottish form, the offence of executing works to a scheduled monument without scheduled monument consent, which is digging rather than sweeping a coil (AMAA 1979 s.2). The prison element is Historic Environment Scotland's own wording, quoted from their own page, and we could not trace it to section 2 or section 42, neither of which provides for imprisonment. Read it as HES stating the risk, not as a penalty printed in those sections.

What happens to what you find, and why the answer changes at the border

In England, Wales and Northern Ireland the Treasure Act 1996 catches a defined class of object. Section 8 requires a person who finds an object he believes or has reasonable grounds for believing is treasure to notify the coroner for the district in which it was found before the end of the notice period, and s.8(2) sets that at fourteen days beginning with the day after the find, or if later the day the finder first has reason to believe it is treasure. Failure is punishable under s.8(3) on summary conviction by "imprisonment for a term not exceeding three months", a fine not exceeding level 5, or both, with a reasonable excuse defence at s.8(4) (Treasure Act 1996 s.8). Objects outside that class normally belong to the landowner: the Portable Antiquities Scheme's Code of Practice states that finds "will normally be the property of the landowner, so to avoid disputes it is advisable to get permission and agreement in writing first regarding the ownership of any finds subsequently discovered" (PAS Code of Practice).

Scotland is a different system, not a variation on the same one.

So the Scottish class is not defined by what the object is made of, reporting is a legal obligation rather than a code of practice, and that public parks line confirms the landowner rule does not soften on publicly owned ground. Crown Estate foreshore has its own answer again, in clause 5 of the Terms and Conditions, which is rarely published.

The permissive right is real but conditional, and the popular line that anything found on a Crown Estate beach is yours to keep is not what the Terms and Conditions say. Surface-only searching, refilling every hole however small, the fourteen-day reporting duties and the equal split on items of value are set out in metal detecting on UK beaches. The Thames needs its own permit from the Port of London Authority. On gold specifically, panned gold is a separate question covered in the UK gold panning laws guide, and the overlap with gold-bearing ground is in detecting for gold in the UK.

The five-minute permission check

1. Confirm who owns it, not who farms it. Only a National Trust archaeologist can authorise detecting on Trust land, and a National Park Authority may own no land at all.
2. Ask about agri-environment agreements. Countryside Stewardship or Environmental Stewardship, and are any fields excluded? Under Higher Level Stewardship the restricted sites are named in the Farm Environment Plan.
3. Check the designations. England: the Defra MAGIC map at magic.defra.gov.uk, with SSSI status explained in the Government's SSSI guidance. Scotland: PastMap, as Historic Environment Scotland directs. Wales: Cadw's scheduled monument records.
4. Check whether it is CRoW access land. The open access right does not extend to you while you have a detector with you.
5. Check the public landowner, not just the council. On Forestry England land byelaw 5(ix) applies and the route is the written authority of the Commissioners. On foreshore, confirm ownership on the Crown Estate's Foreshore and Estuary Ownership Map first.
6. Agree what happens to finds, in writing, as the PAS Code of Practice recommends.
7. In Northern Ireland, establish whether the search will disturb the ground, because that is what triggers the licence requirement.

Where the honest answer is that we could not confirm it

• The Welsh Government Woodland Estate. Natural Resources Wales runs a "Check if you are allowed to use land we manage" service that lists metal detecting among the activities it covers, but the answer could not be extracted from the page when checked on 10 September 2026. Use the NRW checker directly for land NRW manages, rather than assuming the Forestry England byelaw position carries across the border.
• The National Council for Metal Detecting's Code of Conduct. The Code exists, and some councils gate their permits on membership of a national detecting body, Arun District Council being a verified example. No sentence of the Code could be read from source on 10 September 2026, so nothing is quoted from it here.

Everything else on this page is quoted from the body that publishes it, with the link beneath it, so you can check it before you check the ground. The same permission logic sits behind every entry on the UK Gold Prospector map, and the free beginner's pack covers starting out legally.
