Coppicing for Firewood: Cutting, Rotation and Seasoning the UK Way

Coppicing is one of the oldest and most satisfying jobs on a wooded holding. You cut a broadleaved tree close to the ground in winter, and instead of dying it throws up a cluster of fast, straight new stems from the stump, known as the stool. Cut a block each year on a set cycle and you have a supply of poles that renews itself without replanting, for firewood, fencing, hedging stakes and craft wood. It is genuinely a crop you can harvest for a lifetime from the same trees.

This guide covers what coppicing is and why it suits a homestead, which trees to cut and on what rotation, how and when to cut the stool, how to protect the regrowth, the law you must not skip, and, crucially, how to season the wood so it actually burns well. Two parts of this are matters of law and safety rather than opinion: whether you need a felling licence, and how to use a chainsaw safely. Read those sections carefully.

This is general guidance, not legal advice, and it is not a substitute for hands-on training with a saw. Rules differ across the four nations and change over time, so confirm the current position with the sources below and, for the licence question, with the Forestry Commission or your equivalent national body.

What coppicing is, and why it suits a homestead

Coppicing works because many broadleaved trees do not die when cut down. Sever the trunk near ground level and dormant buds around the base burst into life, sending up a ring of vigorous new shoots. The Woodland Trust describes the result as "dense stands of multi-stemmed trees" that "grow back faster to provide a sustainable timber supply" than waiting for mature timber. The Forestry Commission notes these shoots are typically ready for harvesting after 7 to 20 years, depending on the product you want.

The reason it fits a homestead so well is that it turns a single cut into a repeating harvest. As the Forestry Commission puts it, coppicing gives "a regular crop of products on a relatively short rotation when compared to conventional timber, for example 10 years vs 60 years," and the regrowth "provides a continuous crop for harvesting without the need to replant." Regular coppicing can also keep the individual stools alive for centuries and, done in blocks, boosts woodland wildlife by letting light down to the woodland floor.

A coppice is usually worked in blocks called coupes. You divide the wood into roughly equal blocks and cut one coupe each year, so that at any time you have stems of every age from freshly cut to nearly ready. Well-formed trees left standing among the coppice create a traditional "coppice with standards" system, giving you larger timber and seed trees alongside the poles. One honest caveat from the Forestry Commission: the first restoration cut of a long-neglected coppice "usually only provides firewood," so do not expect craft-quality poles straight away.

Which trees coppice, and on what rotation

Most native broadleaves coppice. The Woodland Trust lists oak, sweet chestnut, willow, lime, hornbeam, field maple, rowan, alder and hazel among the usual candidates, and the Forestry Commission singles out hazel, willow, sweet chestnut and oak as good species. The rotation, meaning how many years you leave the regrowth before cutting again, depends on the species and what you want to make.

Species	Typical cycle	Traditional use
Hazel	About 7 years	Hurdles, hedging stakes, pea sticks, bean poles
Sweet chestnut	About 15 years (sometimes 15 to 20)	Fencing, stakes, cleft palings
Hornbeam	15 to 25 years	Firewood, charcoal
Oak	15 to 25 years	Firewood, building material
Willow	Short rotation of a few years	Basketry, biomass, living structures
Ash	Coppices vigorously (check tree health first)	Firewood, tool handles

For a firewood-first holding, lean on the denser hardwoods. Defra's own wood-fuel guidance is clear that hardwoods, "deciduous, broadleaved tree species, such as Oak, Ash, Birch," are "generally better as firewood as they tend to be denser and burn for a long period of time," while softwoods "are less dense so will burn faster and compared to a similar sized hardwood log will provide less heat." In practice that puts oak, ash, hornbeam and beech at the top for sustained, high heat, with birch burning hot but fast and softwoods best kept for kindling.

A note on ash: it coppices strongly and is excellent firewood, but ash dieback has spread widely across the UK, so check the health of any ash before you build a supply around it.

When and how to cut the stool

Timing matters. Coppice in the dormant season, which the Woodland Trust gives as "late September to early March when trees are dormant." Cutting when the sap is down gives the strongest regrowth the following spring, keeps you clear of the main bird-nesting season, and is simpler when the undergrowth has died back. Avoid cutting in hard frost or during active spring and summer growth.

Young trees are usually cut for the first time once they are "growing vigorously," often after 5 to 6 years. The cut itself follows a few simple principles. Cut single stems as close to the ground as possible, and on an established stool cut just above the previous cut. Make a clean cut that does not tear the bark away from the wood, and slope it slightly so rainwater runs off rather than sitting on the stool and rotting it. Woodlands.co.uk describes angling the cut around 15 to 20 degrees from horizontal, with the low side facing outward from the centre of the stool. On fast, low species like hazel a low, near-flat cut encourages new roots; longer-rotation species like oak suit a more sloping, pruning-style cut.

Protecting the regrowth

Fresh coppice shoots are soft, sweet and right at browsing height, so protecting them is not optional. The Forestry Commission is blunt that deer browsing is "especially detrimental to coppice since it's within the deer browse level for most of its growing cycle," and that repeated browsing "can even kill stools." Rabbits, hares and livestock will take the new growth too.

You have three main options, and many people combine them:

• Fencing. The Woodland Trust suggests a fence around 1.8 metres (6 feet) high, kept up for at least two years until the shoots are out of reach. You can move the fencing from coupe to coupe as you rotate through the wood.
• Dead hedges. Pile the brash (the "lop and top" left after cutting) into a woven barrier around a group of stools. It is free and uses material you would otherwise have to clear.
• Brash over the stool. Heaping cut branches directly on a stool deters browsing, though the Woodland Trust warns it "may suppress regrowth or reduce the straightness of new stems," so it is a trade-off.

Where deer numbers are high, fencing or dead hedges alone may not be enough, and deer management becomes part of the picture. Cutting in blocks and keeping coupes a sensible size also matters, because the stools need plenty of light to regrow strongly.

The law: do you usually need a felling licence?

This is the part homesteaders most often get wrong. In England you need a Forestry Commission felling licence to fell growing trees unless an exemption applies, and this holds whoever owns the land. Licences are free in England, and everyone involved in unlicensed felling, including landowners, tenants, agents and contractors, can be prosecuted if a licence was required.

Two more warnings. First, the exemption is not a free pass over everything else. A Tree Preservation Order, a conservation area, or a Site of Special Scientific Interest can each require separate consent even when no felling licence is needed, and cutting a protected tree without permission is a criminal offence. Second, the Wildlife and Countryside Act 1981 makes it an offence to damage or destroy an active bird's nest, all year and everywhere, which is another good reason to keep coppicing to the dormant winter months.

The rules are devolved, so do not carry English figures across borders. In Scotland, Scottish Forestry runs felling permissions and the everyday exemption is up to 5 cubic metres per landholding per calendar quarter, with no separate 2 cubic metre sale sub-limit. In Wales, Natural Resources Wales issues licences and the exemption is under 5 cubic metres per quarter. In Northern Ireland the trigger is area-based rather than volume-based, so felling in private woodland of 0.2 hectares or more needs a licence. Check your own nation's body before you cut.

From log to fuel: seasoning to 20% moisture

Cutting the wood is only half the job. Green, freshly felled logs are far too wet to burn well. Defra's guidance is explicit that green logs "are not suitable for burning in a domestic stove or open fire until they have been dried to 20% moisture content or less," because modern stoves are designed around fuel "with a moisture content of up to and including 20%." Burn wet wood and you get less heat, a lot more smoke, blackened glass, and tar building up in the flue that raises the risk of a chimney fire.

Seasoning firewood, step by step

1. 1

   Cross-cut and split soon after felling

   Cut to stove length and split logs down. Defra advises splitting to less than about 10 cm across, which lets moisture escape from the centre of the log far more easily than leaving it in the round.

2. 2

   Stack off the ground

   Build the stack on bearers so it is not sitting in wet soil, in a sunny, breezy spot. The ideal is for the prevailing wind to blow straight through the stack.

3. 3

   Cover the top, leave the sides open

   Use a waterproof cover over the top but keep the sides open for airflow. Rain off, air through. Wrapping the whole stack in a tarp traps moisture and slows drying.

4. 4

   Give it time

   Air drying naturally takes, in Defra's words, 'two summers or more'. As a working rule, allow roughly one to two years. Wood felled in summer holds more sap and takes longer.

5. 5

   Check before you burn

   Split a few sample logs and press a moisture meter to the freshly exposed inner face, not the outer bark. You are aiming for 20% or less. A dry log is lighter, sounds hollow when tapped, and often has cracked ends and loose bark.

Burning well, and the rules on selling wood

If the firewood is purely for your own stove, seasoning it properly is the whole job. If you sell any of it, England has specific rules on top of the felling limits above. Under Defra's "Ready to Burn" scheme you "can only supply or sell wood fuel in volumes of less than 2 cubic metres if it is certified as 'Ready to Burn'," a certification that "confirms it has a moisture content of 20% or less." Sell in larger loads (2 cubic metres or more) and you do not need certification, but you must provide the customer with a Defra notice explaining how to dry, store and check the wood. Local authorities enforce this and can issue a 300 pound fixed penalty, or a larger court fine, for selling wet or mislabelled wood.

There is also the question of where the wood is burned. In a smoke control area you may only burn wood on a Defra-exempt appliance, and Defra warns you "could face a fine of up to 1,000 pounds if you break the law." If you sell to customers, you must tell them this. None of it is onerous, but it is worth knowing before you turn a woodpile into a side-line.

Before you cut: check these

1. Have you checked for a Tree Preservation Order, a conservation area or an SSSI on the trees or the site?
2. Do you need a felling licence, or are you genuinely inside an exemption for your nation, and have you measured diameters at 1.3 metres for the right threshold (8 cm, or 15 cm for coppice)?
3. If you plan to sell, are you inside the sale sub-limit (2 cubic metres a quarter in England), and can the finished wood meet Ready to Burn?
4. Are you cutting in the dormant season and clear of active bird nests?
5. Are you trained and equipped for chainsaw work, with full PPE and someone who can call for help, or should a professional do the felling?
6. Have you a plan to protect the fresh regrowth from deer and stock for at least two years?
7. Is there somewhere dry and airy to season the wood for a year or two before you burn it?

When in doubt on the law, check the current gov.uk felling guidance and contact the Forestry Commission (or Scottish Forestry, Natural Resources Wales, or DAERA's Forest Service for the other nations) before any cutting, and speak to your local authority about selling and smoke control. On the saw, when in doubt, get trained or bring in a professional.
