Oak Firewood: Why It's Worth Waiting For

Oak firewood has a reputation among people who burn wood, and it's earned. It's also the wood most often sold badly — and a load of underseasoned oak will give you a worse evening than almost anything else you could put in a stove.

Both of those things are true for the same reason. Here's what's actually going on, and how to buy it and burn it so you get what you paid for.

Is oak good firewood?

Yes — and specifically, oak firewood is good at things other woods aren't.

Every dry wood releases roughly the same heat per kilogram. Where species differ is density: how many kilograms you get in a given volume. Oak is one of the densest hardwoods commonly sold in the UK, which means a bag of oak weighs considerably more than the same bag of birch or poplar. More mass in the same space is more fuel in the same space.

In practice that shows up three ways:

It lasts longer. A load of oak on a good fire will burn down over a noticeably longer period than a lighter species. Fewer trips to the log basket over an evening.

It holds a steadier heat. Lighter woods tend to catch fast, flare, and drop away. Oak comes up more slowly and then sits there. If you want a stove that's still warming the room two hours after you last touched it, that's oak.

The embers stay alive. Oak leaves a deep bed of coals that will often still be glowing in the morning — which makes relighting a matter of kindling and a bit of air rather than starting from cold.

What oak is not good at is starting a fire. It's slow to catch, and trying to light a cold stove on oak alone is the fastest route to deciding it's overrated.

The catch: oak takes years to season

This is the part that matters most, and the part most people never hear.

Freshly felled oak can be half water by weight. Its cell structure is tight and it holds that water stubbornly — far more stubbornly than ash or birch, which is why ash has a reputation for burning almost green and oak absolutely does not.

Getting oak firewood down to a burnable moisture content takes a long time. Split, stacked with airflow through it and covered on top, you're looking at two years as a realistic minimum, and often longer. There's no shortcut in the open air. Anyone offering you oak felled last winter is selling you a problem.

Burn oak that hasn't got there and you'll get all of it at once: hissing and steaming rather than burning, a fraction of the heat you paid for, a stove glass that blackens within minutes, and a flue accumulating deposits far faster than it should. The energy that should be heating your room goes into boiling water out of the log instead.

Nearly everything said against oak traces back to this. It isn't the wood. It's the drying.

Seasoned or kiln dried?

Both get you to the same place — under 20% moisture, which is the number that actually decides whether a log burns well.

Seasoned oak has been split, stacked and air-dried on site over years. It's the traditional route, it uses no energy beyond the weather, and it's better value. What varies is consistency: air drying is at the mercy of where a bag sat in the stack and what kind of summer it got.

Kiln dried oak finishes the job under controlled conditions. Every bag comes out at the same moisture content, it lights more readily, and it's the easier option if you want zero fuss. You pay for the energy that went into it.

If you burn most evenings through winter and you've got somewhere dry to keep a decent quantity, seasoned is the sensible buy. If you burn a few nights a week and want it right every time, go kiln dried.

The thing worth checking either way is whether the merchant dried it themselves or bought it in already dry. It's the difference between someone who knows how long that particular timber has been sitting and someone repeating what a supplier told them.

How to burn oak properly

Four things, and the first is the one that matters:

Don't start on it. Build the fire with kindling and a faster-catching log — birch, or a lighter mixed hardwood. Get a proper bed of embers established first. Oak goes on after that. Loaded onto a cold stove it will smoulder, and you'll wonder what the fuss was about.

Give it air early. Oak needs a decent draw to get going. Open the air control while it's catching, then bring it back once the log has taken and you're into the steady burn.

Don't choke it down overnight. It's tempting with a wood that burns as long as oak does, but starving a stove of air is what produces smoke and tar rather than heat. Let it burn properly and let the ember bed do the overnight work.

Mix your species. There's no rule saying a fire has to be one wood. Birch or ash to establish it, oak to hold it. That's how most people who burn a lot end up doing it.

How oak compares

	Lights	Burns	Best for
Oak	Slowly	Long, steady, deep embers	Evening heat, overnight
Ash	Easily	Even and reliable	The all-rounder
Birch	Very easily	Fast and bright	Getting a fire going

None of these is the "best" wood — they do different jobs. A basket with birch at the bottom and oak on top will serve you better than a basket of any one of them.

What oak costs, and how we sell it

We put our oak out once a year, when the batch that's been working its way through the yard is finally ready. It's £140.00 per bulk bag, with flat £10 delivery wherever you are across Leicestershire, Derbyshire, Nottinghamshire, Northamptonshire, Warwickshire and the West Midlands — no distance surcharge.

It goes every year, usually faster than the year before, and there's no restocking it. Next year's oak is already in the yard waiting its turn, and it'll be a good while yet.

Everything leaves us under 20% moisture, checked before it goes on the lorry. If you're not sure how many bags you need, ring us on 0116 216 2060 and we'll work it out with you — it's a two-minute conversation and it beats guessing.

Frequently asked questions

How long does oak need to season?

At least two years split and stacked with airflow, and often longer depending on how it was stored. Oak holds water more stubbornly than most species, and there's no way to hurry air drying.

Can you burn oak firewood in a log burner?

Yes — it's one of the best woods for a stove, provided it's properly dry. Get the fire established on something lighter first, then load the oak onto a bed of embers.

Is oak better than ash?

For sustained heat and overnight embers, oak. For ease of lighting and reliability, ash. Most people who burn a lot use both.

Why is oak firewood more expensive?

Because of the years it spends occupying space in a yard before it can be sold. You're paying for time as much as timber.

Does oak need to be kiln dried?

No. Properly air-seasoned oak burns just as well. Kiln drying buys consistency and convenience, not a better fire.

How much oak firewood do I need for winter?

It depends on your stove, your house and how often you light it. Ring us and we'll give you an honest figure rather than an upsell.
