Off-Grid Camping in the UK: Power, Water, Waste and Where to Go
· Updated
Off-grid camping means running a trip with no mains supply: you generate or carry your own power, you carry and treat your own water, and you take every scrap of waste out again. Get those three right and the location almost sorts itself out, whether that is a backpacking pitch on Dartmoor or a basic five-van field with no electric hook-up.
This is the practical version. It is a spoke of our wider guide to wild camping in the UK, and it comes from Camping Sites in Britain, where you can find and compare campsites, caravan parks and remote pitches across the country. Off-grid and wild camping overlap, but they are not the same thing: you can camp off-grid on a fully legal certificated site, and you can wild camp with a power bank in your pocket.
Power: how to keep things running without a hook-up
The realistic off-grid setup is a portable power station charged by a folding solar panel, topped up before you leave home. That combination covers phones, lights, a coolbox and a camera for a weekend without any mains at all. If you rely on an electric hook-up instead, that is a different style of trip entirely, and our guide to electric hook-up camping covers powered pitches in full.
The three sources you will actually use are a leisure battery, a portable power station or a solar panel, and most off-grid campers run some combination. Here is how they compare.
| Source | Typical size | Best for | Watch out for |
|---|---|---|---|
| Leisure battery (12V) | 75 to 110Ah | Campervans and trailers, running a 12V fridge and lights | Heavy, needs charging and a proper setup, not for backpacking |
| Portable power station | 300 to 2,000Wh | Tent and van campers, charging phones, laptops, a coolbox | Bigger units are heavy, so match the size to the trip |
| Folding solar panel | 100 to 200W | Topping the above back up on a sunny pitch | Output drops sharply under British cloud, so overspec it |
To size it, add up what you draw. A phone charge is roughly 15Wh, a night of tent lighting a few Wh, and a 12V coolbox around 45W while its compressor runs. A 500Wh power station will keep a couple of phones, lights and a small coolbox going across a weekend, and a 100W to 200W folding panel will claw a useful amount back on a bright day. In practice, arrive fully charged and treat solar as a top-up, not your main supply, because Britain does not do reliable sunshine.
Water: carry it, or treat what you find
You have two options off-grid: carry all the water you need, or treat water from a stream or tap you cannot vouch for. Both are fine, and most trips use a bit of each.
Plan on two to three litres per person per day for drinking, plus more for cooking and washing. Water weighs one kilogram per litre, so a full day's supply for two people is heavy, which is why treating on the move matters for anything longer than an overnighter. Fill up from a known safe tap wherever you can.
Filtering and purification, and the difference
A filter removes bugs by physically straining them out; purification kills or deactivates what a filter can miss. A squeeze or pump filter rated to 0.1 microns (Sawyer and Katadyn are the common names) removes bacteria and protozoa such as Giardia and Cryptosporidium, which are the realistic risks from UK hill water, usually thanks to livestock and deer upstream. For belt-and-braces treatment, back a filter up with one of these:
- Boiling. A rolling boil for one minute kills everything that matters. Reliable, but it uses fuel and time.
- Chemical tablets. Chlorine dioxide or chlorine tablets (Aquatabs and similar) are light and cheap. Follow the stated contact time before drinking, usually 30 minutes.
- UV pens. A battery UV steriliser treats clear water in about a minute, but it does nothing for cloudy water, so filter first.
Take water from flowing sources rather than standing pools, above any obvious livestock, and never assume a Highland burn is clean just because it looks it. If you want the full method, our sibling guide to essential skills for wild camping covers sourcing and treating water in the field.
Waste: pack it out, and use the right disposal point
The rule off-grid is simple: everything you carry in, you carry out, including food scraps, which do not belong buried in a fragile upland and will be dug up by wildlife. Bag your rubbish and take it home or to a proper bin.
Human waste needs more thought. If there is no toilet, dig a small hole 15 to 20cm deep, at least 30 metres (50 paces) from any water, path or pitch, and cover it fully afterwards. Carry your used toilet paper out in a sealed bag rather than burying it, because it lingers for months. In heavily used or sensitive spots, the responsible move is to pack the lot out using a proprietary waste bag.
If you run a portable chemical toilet in a van or family tent, it must be emptied at a designated chemical disposal point, often signed as an Elsan point, at a campsite or service area. Never empty it into a normal drain, a public toilet or the ground. This is why a basic certificated site earns its keep on an off-grid trip: many have a chemical disposal point and a fresh water tap even when they have nothing else. All of this sits under the Countryside Code and Leave No Trace, which are worth reading before your first trip.
Staying connected, or deliberately switching off
Mobile coverage in the places worth camping off-grid is patchy at best, so decide in advance which camp you are in. If you want to stay reachable, download your maps for offline use before you leave signal, carry a power bank purely for your phone, and keep it in a warm pocket, because cold flattens a battery fast. An OS Maps subscription or a downloaded route means your navigation does not depend on a bar of signal.
For genuinely remote trips where a phone will not reach anyone, a personal locator beacon or a satellite messenger such as a Garmin inReach gives you an emergency link that does not need mobile coverage. If you would rather use the trip to switch off entirely, that is the whole appeal for a lot of people, and it pairs well with learning a hands-on skill; the best outdoor survival courses in the UK are a good way in.
Where you can actually camp off-grid
Where you can legally pitch depends entirely on which country you are in, and this is the part people most often get wrong. Off-grid does not mean rules-free.
Scotland: a legal right, with a Loch Lomond exception
Scotland is the easiest place in Britain to camp off-grid, because the Land Reform (Scotland) Act 2003 and the Scottish Outdoor Access Code give you a right to wild camp on most unenclosed land, as long as you camp responsibly, in small numbers, and away from homes and roads. The main exception is the camping management zones around Loch Lomond and the Trossachs, where between 1 March and 30 September you need a permit or must use a campsite. Everywhere else, follow the code and leave no trace. Our guide to choosing a site for wild camping in Scotland goes deeper on picking a legal, low-impact pitch.
Dartmoor: the one legal right in England
Dartmoor is the only place in England where you have a legal right to backpack wild camp without asking the landowner. The UK Supreme Court confirmed that right on 21 May 2025, overturning a challenge by two landowners. It applies to lightweight, one or two night backpack camping on the commons, following the National Park Authority's map and rules, not to campervans or car-based camping. Dartmoor sits in Devon, and you will find plenty of served pitches nearby in our Devon campsite listings if you want a base with facilities.
The rest of England, Wales and Northern Ireland
Everywhere else in England, plus all of Wales and Northern Ireland, wild camping needs the landowner's permission. Some upland areas, such as parts of the Lake District and Snowdonia, have a long-standing tolerance of discreet, high-level, one-night camping, but that is tolerance, not a right, and you can be asked to move on. The reliable off-grid option here is a small certificated site.
Remote certificated sites: the easy off-grid base
A certificated location (CL) or certificated site (CS) is a small, licence-exempt pitch, typically limited to five caravans or motorhomes plus a few tents, run on a farm or in a field. They are usually basic by design, often with no electric hook-up, sometimes just a tap and a chemical disposal point, which is exactly what you want for an off-grid weekend with a legal, bookable pitch and no crowds. They are the middle ground between a full campsite and a wild pitch, and there are hundreds tucked into corners of the country you would never otherwise find. For real solitude, browse remote spots in our Highlands campsite listings or the wider CSIB campsite directory, and read camping off the beaten path for more on finding the quiet ones.
Frequently asked questions
Is off-grid camping legal in the UK?
Yes, if you do it in the right place. You can wild camp off-grid by right in Scotland (outside the Loch Lomond permit zones from 1 March to 30 September) and on Dartmoor. Everywhere else in England, Wales and Northern Ireland you need the landowner's permission, or use a certificated site.
How do I power my devices off-grid?
Charge a portable power station at home and top it up with a 100W to 200W folding solar panel. A 500Wh station runs phones, lights and a small coolbox for a weekend. Campervans usually add a 12V leisure battery for a fridge and lighting.
Can I drink water from a stream while camping?
Not untreated. UK hill water can carry Giardia and Cryptosporidium from livestock and deer. Filter it through a 0.1-micron filter, then boil for one minute or use chlorine dioxide tablets. Take flowing water from above any grazing animals, never a standing pool.
What do I do with toilet waste when camping off-grid?
Bury solid waste in a hole 15 to 20cm deep, at least 30 metres from water, paths and pitches, and carry your toilet paper out. Empty a portable chemical toilet only at a designated chemical disposal or Elsan point, never into a drain or the ground.
What is the difference between off-grid and wild camping?
Wild camping is about where you pitch: on open land, away from campsites. Off-grid is about self-sufficiency: your own power, water and waste. You can camp off-grid on a fully legal certificated site, and you can wild camp while still carrying a power bank.
How do I stay contactable in areas with no signal?
Download offline maps before you lose coverage and carry a power bank for your phone. For remote trips, use a personal locator beacon or a satellite messenger such as a Garmin inReach, which work without mobile signal and can summon help in an emergency.
The short version
Off-grid camping comes down to three jobs: carry or generate your power, treat or carry your water, and pack every bit of waste back out. Sort those and you can pitch almost anywhere the law allows, from a Dartmoor common to a five-van field in the hills.
Start with the rules for where you are going, plan your power and water before you leave, and read the full guide to wild camping in the UK next. When you want a legal, quiet base with just enough facilities, the CSIB campsite directory is the place to find one.
