7 Best Logs for Burning: A UK Guide to Better Fires
The best log for burning is dry hardwood below 20% moisture, but the right choice also depends on whether you want a long overnight burn, fast heat, easy lighting or clean cooking. Below are the seven best logs and wood fuels for UK fires, what each one does best, and how to get the most from them.
One rule applies to every option here: whatever you burn, it must be dry. A damp log of any species burns poorly, smokes heavily and wastes heat. Look for kiln dried, Ready to Burn fuel below 20% moisture.
1. Kiln dried oak logs: best for long, slow burns
Oak is the densest of the common UK hardwoods, which makes it the best choice for long, slow, steady fires. That density means it releases heat gradually and forms a deep bed of glowing embers, so it keeps a room warm for hours with little intervention, ideal for overnight burning or a long evening by the stove.
The trade-off is that oak takes a little more effort to get going, so it's best lit with kindling or alongside a faster-catching log like birch.
- Best for: wood burners, open fires, overnight heat
- Burn: slow · Heat: very high · Lighting: needs kindling
2. Kiln dried ash logs: best all-rounder
Ash is the firewood many people reach for first, and for good reason: it burns steadily, gives strong heat and lights more easily than most hardwoods. That balance makes it the best everyday choice for a wood burner.
- Best for: everyday stove use
- Burn: medium · Heat: high · Lighting: easy
3. Kiln dried beech log: best for steady, consistent heat
Beech is a dense hardwood that delivers a reliable, even burn, which makes it popular for sustained heating and for wood-fired cooking where steady temperature matters. It's a little harder to light than ash, but it rewards you with consistent warmth.
- Best for: steady heat, wood-fired cooking
- Burn: medium · Heat: high · Lighting: good
4. Kiln dried birch logs: best for easy lighting and quick heat
Birch catches quickly and burns with a bright, attractive flame, so it's the best log for getting a fire going fast or taking the chill off a room. Its bark even works as natural kindling. It's slightly less dense than oak or beech, so many people use birch to establish a fire and then add a denser log to keep it going.
- Best for: lighting fires, fast warmth
- Burn: faster · Heat: medium-high · Lighting: very easy
5. Softwood logs: best for kindling and fire-starting
Softwoods like pine and spruce ignite fast and burn hot but quickly, which makes them excellent kindling and fire-starters rather than a main fuel. As long as it's properly dried below 20% moisture, softwood is safe to burn, it's just better suited to getting started than to long, sustained fires.
- Best for: kindling, getting a fire established
- Burn: fast · Heat: medium · Lighting: very easy
6. Heat logs and briquettes: best for convenience and long burns
Heat logs and wood briquettes are made by compressing dried sawdust and wood shavings under high pressure into dense blocks, with no glues or binders. Because they're manufactured to a very low, consistent moisture content (often below 10%), they light easily, burn cleanly and give a predictable, often very long burn, and some night briquettes can burn for several hours. They're compact to store and a reliable backup or main fuel for anyone who wants minimal fuss.
- Best for: convenience, long predictable burns, easy storage
- Burn: long · Heat: high · Lighting: easy
7. Kiln-dried fruitwood: best for cooking and aroma
Fruitwoods such as apple and cherry are hardwoods prized less for raw heat and more for the pleasant aroma and clean, manageable flame they produce. That makes them a lovely choice for pizza ovens, BBQs and atmospheric fires, where the fragrant smoke can even add subtle flavour to food. They're usually a treat alongside your main fuel rather than a primary heat source.
- Best for: wood-fired cooking, ambience
- Burn: medium · Heat: medium · Lighting: good
Quick comparison
| Log type | Burn speed | Heat output | Best for |
|---|---|---|---|
| Oak | Slow | Very high | Long & overnight fires |
| Ash | Medium | High | Everyday stove use |
| Beech | Medium | High | Steady heat, cooking |
| Birch | Faster | Medium-high | Easy lighting, quick heat |
| Softwood | Fast | Medium | Kindling, fire-starting |
| Heat logs / briquettes | Long | High | Convenience, long burns |
| Fruitwood | Medium | Medium | Cooking, ambience |
How to choose
- For consistent home heating: kiln-dried oak, ash or beech, dense hardwoods that hold heat.
- For atmosphere and quick fires: start with birch or softwood kindling to light fast, then add a denser hardwood.
- For convenience: heat logs and briquettes give a clean, long, predictable burn with easy storage.
- For cooking: kiln-dried hardwood or fruitwood for pizza ovens and BBQs.
Whatever you choose, the single biggest factor in how well it burns is moisture, dry, Ready to Burn fuel below 20% every time. Browse Calido's kiln dried logs and briquettes to find the right fuel for your fire.
