Ask this question online and you will get two confident answers that contradict each other. One says magnet fishing is perfectly legal. The other says it is banned on the canals. Both are half right, and the half that is missing is the part that actually matters when someone walks over and asks you to stop.
The short answer
- No UK statute makes magnet fishing a criminal offence. There is no Magnet Fishing Act. Nothing in the law singles out dragging a magnet through water.
- The Canal & River Trust does not permit it on its roughly 2,000 miles of canal and river in England and Wales. But that is a landowner’s policy, not a byelaw and not a law, and the Trust’s own published policy cites no legislation for it.
- Scotland is the mirror image. It is openly permitted on the canal network, but only with written permission from Scottish Canals and Scheduled Monument Consent from Historic Environment Scotland. Go without the consent and the exposure is serious: fines of up to £50,000.
- You always need the landowner’s permission. Every stretch of water in Britain belongs to somebody, and so does the bed underneath it.
- What you pull out is not automatically yours.
England and Wales: no offence, but no right either
Start with what is not there. Parliament has never created an offence of magnet fishing. You will not find it in the Theft Act, the Scrap Metal Dealers Act, or anywhere else. The activity itself is not criminal.
That is where most articles stop, and it is why so many people arrive at the canal believing they are in the clear.
What they miss is that the absence of a criminal offence is not the same as a right to do it. Land law fills the gap. The bed of a canal is owned by somebody. The bank you are standing on is owned by somebody. Permission to be somewhere for one purpose does not extend to every purpose: a public right of way along a towpath lets you walk, it does not let you extract objects from the water beside it.
So the correct framing is not “is it legal” but “whose water is it, and have they said yes.”
What the Canal & River Trust actually says, and what it means
This is where the internet gets it wrong in both directions.
The Trust’s public position is blunt. Its fishing FAQ states that “Magnet fishing is not allowed on our waterways,” and explains the activity is “not actually angling.”
Its fuller policy goes further. The Restricted Activities on Trust Land statement says at section 3.1: “We do not permit magnet fishing on our waterways due to the potential hazards it poses to:” and then lists four:
- navigation
- the environment and other towpath users, if items found are abandoned nearby
- any items of a historic nature extracted from the waterway
- those engaging in magnet fishing, if dangerous items are extracted or if an accident occurs
Read that document looking for the legal basis and you will not find one. It cites no byelaw. It cites no statute. It is a policy — the Trust exercising its rights as the landowner over its own water.
That distinction has practical consequences, and it cuts both ways.
It means being caught magnet fishing on a Trust canal is not, by itself, a criminal matter. In the ordinary case you will be asked to stop and to leave. Ignore that and you are a trespasser, which is a civil wrong rather than a crime, and the Trust can pursue it as such.
It also means the ban is real and you have no standing to argue with it. “There’s no law against it” is true and completely beside the point. It is their water. They have said no. A landowner does not need a statute to refuse you permission on their own land, any more than a farmer needs one to refuse a detectorist.
The Trust is not the only water authority in England and Wales. Rivers, reservoirs, docks, lakes and private ponds have their own owners, and some are considerably less relaxed than others. There is no national rule to fall back on. You ask, every time.
Scotland: stricter on paper, clearer in practice
Scotland handles this in a way nowhere else in the UK does, and the detail is worth getting right.
Magnet fishing is permitted on the Scottish canal network — the Caledonian, Crinan, Forth & Clyde, Union and Monkland canals — but you need two separate permissions before you start.
First, permission from Scottish Canals as landowner. The request goes by email and has to include your name, address, phone number and email, which canal you want, the exact location by grid reference or what3words, the dates, whether you intend to fish from the bank or from a boat, and any group you belong to.
Second, Scheduled Monument Consent from Historic Environment Scotland. Most of Scotland’s canal network is a scheduled monument. So are some historic lochs, including Linlithgow, Duddingston and St Margaret’s, and the water around a number of important historic sites. You can check whether a specific spot is covered on PASTMAP before you apply.
Scottish Canals warns that an SMC application “can take up to two months to be reviewed.” Both the permission and the consent are free, and the activity is adults only.
The penalty for skipping the consent is the single most under-reported fact in this whole subject. Magnet fishing a scheduled area without SMC would, in Scottish Canals’ words, be “viewed as unauthorised work on a scheduled monument” — and that “could lead to fines of up to £50,000.”
Consent is not theoretical. Official Magnet Fishing Scotland currently holds it for the Union Canal between Leamington Lift Bridge and Hermiston Aqueduct, and is applying for stretches of the Forth & Clyde and Caledonian.
One more Scottish trap. Historic Environment Scotland classes leaving your finds piled on the towpath as fly-tipping, which carries penalties of up to £40,000. Whatever comes out of the water leaves with you.
Who owns what you pull out
Not you, by default.
In England and Wales, property recovered from land generally belongs to the owner of that land rather than to the person who found it. A rusted bicycle is a nuisance either way, but a dumped safe, a stolen motorbike or something of genuine age is a different conversation, and the Canal & River Trust specifically lists “any items of a historic nature” among its reasons for the ban.
In Scotland the position is tighter still and does not depend on who owns the ground. Under Scots common law, portable antiquities of archaeological or historical significance are Crown property, and finds of that kind must be reported to the Treasure Trove Unit. Failing to report one is an offence. Historic Environment Scotland is clear that this does not extend to modern coins, blades or machine parts — the ordinary scrap that makes up most of what a magnet lifts.
If you recover something that may be stolen property, the sensible route is the police rather than the scrapyard.
The things you do not want on the end of the rope
This is not a theoretical risk and it is the main reason authorities are twitchy.
British canals and rivers were, for generations, where unwanted metal went. Magnet fishers pull out live hand grenades with enough regularity that local forces issue warnings about it, and bomb disposal teams have been called to canals in Burnley, Worcestershire and elsewhere after exactly this. Firearms come up too.
If you bring up something that looks like ordnance:
- Do not move it any further, and above all do not put it in a vehicle.
- Do not take it home to photograph it.
- Move people back from it and call 999.
If you bring up a firearm, leave it where it is, call the police, and wait. Carrying it to a station is not the helpful gesture it sounds like.
If you are going to do it properly
Get permission in writing. Pick water with a known owner you can actually contact — a private lake, a farm pond, an estate — rather than a canal where the answer is already no. Go in pairs. Wear cut-resistant gloves, because wet rusted metal is sharper than it looks. Take everything you lift away with you, including the parts you did not want.
Best first magnet: MAGFISHION 300kg Fishing Magnet Kit (about £20)
A 60mm single-sided magnet with rope, carabiner and gloves in the box. Rated 4.6 stars from over a thousand reviews, which is a far bigger evidence base than most kits in this category. 300kg of pull is plenty for a first season and light enough to throw all afternoon.
Best rated: 250kg 75mm Magnet Fishing Kit with 15m Rope (about £23)
The highest star rating we found at 4.7, though from only 31 reviews so far. The wider 75mm face grips flat plate better than a small magnet does, and 15 metres of rope is more than most bank swims need.
Step up: MAGFISHION 400kg 90mm Fishing Magnet Kit (about £30)
A 90mm face and 400kg of pull. The practical difference is not lifting heavier objects so much as holding on to awkward ones while you draw them in. 4.5 stars from 577 reviews.
Double-sided: Magnetpro 2000lb Complete Kit (about £50)
Double-sided magnets pull from both faces, which roughly doubles your chances on a blind throw into a canal or dock. This one arrives as a complete kit with rope, thread locker and gloves. 4.5 stars from 153 reviews.
For snagged finds: Grappling Hook with 15m Rope (about £28)
Sooner or later the magnet locks on to something too big, too buried or too non-magnetic to move. A folding grapple with its own 10mm rope is how you recover it, and how you get a stuck magnet back.

Frequently asked questions
Is magnet fishing illegal in the UK? No. There is no statute that makes the activity itself an offence anywhere in the UK. What varies is whether the owner of a particular stretch of water permits it, and in Scotland whether the water is a scheduled monument.
Can I magnet fish in a canal? Not on a Canal & River Trust canal in England or Wales — the Trust does not permit it. In Scotland you can, on the Caledonian, Crinan, Forth & Clyde, Union and Monkland canals, with permission from Scottish Canals and Scheduled Monument Consent from Historic Environment Scotland.
What happens if I get caught on a Canal & River Trust canal? You will be asked to stop and leave. The ban is the Trust’s own policy rather than a criminal offence, so in the ordinary case this is a trespass matter, not one for the courts. Refusing to leave is what escalates it.
Do I need a rod licence? No, and one would not help you. An Environment Agency rod licence covers fishing for fish. The Canal & River Trust is explicit that magnet fishing “is not actually angling,” so a licence neither permits it nor is required for it.
Can I magnet fish in a river? Only with the permission of whoever owns that stretch of riverbed and the bank you are standing on. There is no general right, and ownership of river beds in Britain is often split between several parties along a single mile.
How much is the fine in Scotland? Scottish Canals states that magnet fishing a scheduled area without Scheduled Monument Consent could lead to fines of up to £50,000. Separately, leaving your finds on the towpath is treated as fly-tipping, with penalties of up to £40,000.
Who owns what I find? Generally the owner of the land, not you. In Scotland, portable antiquities of archaeological or historical significance are Crown property and must be reported to the Treasure Trove Unit; failing to do so is an offence. Modern coins, blades and machine parts are not caught by that.
What do I do if I pull out a grenade? Leave it exactly where it is, move people away, and call 999. Do not put it in a car. Live ordnance comes out of British canals often enough that local police forces issue warnings about it.
Is magnet fishing allowed in Northern Ireland? There is no statutory ban, but the same principle applies as in England and Wales: the water and the bed belong to somebody, and you need their permission. The Lagan and other waterways have had public warnings issued about recovered ordnance.
