Stacked kiln dried logs

Firewood calculator

How much firewood do I need for winter?

Answer four questions for a planning estimate, then choose the storage option that suits you. Current pack volumes and prices help you decide what to order.

Why people bother

Dry wood is the whole difference

Wet logs hiss, smoke, tar up your flue and give out half the heat you paid for. Properly dried hardwood lights first time and burns clean — which is the entire reason we pay to have it properly kiln dried rather than just selling what comes off the saw.

The short answer

Most UK homes land
between 2 and 5 cubic metres

If you just want a number before you order, these are the bands the trade works to. Our calculator above narrows it down using your stove, your nights and your hours.

These bands match the general guidance published by HETAS and most UK log merchants. Your own house, insulation and stove efficiency will move the number either way.

Getting compared like for like

Loose, stacked, bulk bag,
builder’s bag, barrow bag

More people get caught out by the measure than by the price. Here is what the words actually mean before you compare two quotes.

Loose vs stacked

A loose cubic metre is logs tipped in, air gaps and all. A stacked cubic metre is the same space packed tight, so it holds noticeably more wood. Always ask which one a price refers to.

Bulk and builder’s bags

There is no legal standard size. A “bulk bag” can be anywhere from a third of a cubic metre to a full one, so a cheap bag can easily be the dearer wood.

Nets and barrow bags

Handy for topping up and for tight access, but the most expensive way to buy wood per cubic metre. Fine as a top-up, painful as a whole season.

Logs per cubic metre

Depending on log length and how tightly it is packed, a cubic metre holds somewhere around 200 to 300 logs. Ours are cut to 9–10 inches.

Storage space

Roughly one square metre of floor at a metre high per cubic metre of logs. Two cubic metres takes about the footprint of a small wardrobe.

Weight

A loose cubic metre of kiln dried hardwood weighs somewhere near 350–400kg. Worth knowing before you plan to move it by hand.

We publish the volume and rough weight against every load we sell, so you can price us honestly against anyone else.

Six things that change the number

Why two houses on the
same street burn differently

1

Stove size and efficiency

A 5kW stove sips compared with a 10kW one. A modern Ecodesign stove gets far more heat from the same log than something twenty years old.

2

Open fire or stove

Open fires send most of the heat up the chimney. Plan on roughly three times the wood for the same warmth in the room.

3

Hours, not just nights

Four hours on a Saturday is a different animal to a stove lit at eight in the morning and banked down at eleven at night.

4

How dry the wood is

Wet logs waste energy boiling off water. Under 20% moisture is the target — anything wetter and you burn more to get less.

5

Species and density

Oak and beech are dense and burn long. Birch lights easily but goes quicker. A mixed hardwood load gives you both.

6

Your house

Insulation, ceiling height, draughts and which room the stove is in all move the figure more than people expect.
