How much wood do you need for winter?

As the summer sun fades and the autumn chill sets in, our thoughts naturally turn to cosy evenings gathered around the fire. However, before you light that first log of the season, September brings two crucial considerations for any stove owner or open-fire enthusiast: preparing your winter fuel supply, and making sure your flue is safe to burn.

Every September marks Chimney Fire Safety Week, an annual campaign run alongside fire & rescue services, HETAS, and the Guild of Master Chimney Sweeps. It is a timely reminder to get your chimney inspected, swept, and ready for action before the cold weather hits.

Here is your essential A&C Logs guide to calculating how much firewood you need for winter, alongside key safety steps to keep your home warm and protected.

Why Chimney Fire Safety Week Matters

Most chimney fires are entirely preventable. They typically occur when flammable tar, soot, or creosote builds up inside the flue over time. When ignited, these deposits can burn at extremely high temperatures, leading to structural damage or spreading to the rest of your home.

Beyond fire risks, a blocked or partially obstructed chimney can cause carbon monoxide (CO), a dangerous, odourless gas, to leak back into living spaces.

Essential Safety Checklist Before Lighting Up:

  1. Sweep Before You Burn: Have your flue swept at least once a year (twice if you burn wood heavily) by a qualified chimney sweep.

  2. Burn the Right Fuel: Never burn wet, unseasoned wood or household trash. Wet wood creates excess smoke and accelerates creosote build-up inside your flue. Always choose Ready to Burn certified kiln-dried logs with a moisture content under 20%.

  3. Install CO & Smoke Alarms: Ensure you have working carbon monoxide and smoke detectors installed in the room housing your appliance, and test them regularly.

How Much Wood Do You Need for Winter?

One of the most frequent questions we get at A&C Logs around autumn is: "How many bags or cubic metres should I order?"

While exact requirements vary based on property insulation, stove efficiency, and winter weather severity, most UK homes burning high-quality kiln-dried hardwood fall into one of these usage brackets:

  • Occasional heating for weekends & chilly evenings: 0.5 – 1 cubic metres, or 1 to 2 boxes/ large bags

  • Regular evening heating 4–5 nights a week (Oct to Mar): 1.5 – 2.5 cubic metres, or 3 to 5 boxes/ large bags

  • Daily supplementary heat in the afternoons/evenings: 3 – 4 cubic metres, or 6 to 8 boxes/ large bags

  • Primary heat source all day: 4 – 6+ cubic metres, or 8+ boxes/ large bags

4 Key Factors That Affect Your Wood Consumption

1. Appliance Efficiency

Modern EcoDesign wood-burning stoves burn logs significantly more efficiently than open fires or older appliances. An open fire loses up to 80% of its heat straight up the chimney, consuming up to twice as much fuel for the same level of room warmth.

2. Species & Fuel Quality

Dense hardwoods (such as Ash, Beech, and Oak) offer superior heat output and longer burn times compared to softwoods. Using kiln-dried hardwood means you burn fewer logs per night while keeping your stove clean.

3. Storage & Moisture Control

Always ensure you have enough dry, ventilated storage space before placing a large bulk order. Logs stored incorrectly outdoors can reabsorb atmospheric moisture, dropping their burning efficiency and increasing soot deposits in your flue.

4. Buying Strategy: Bulk vs. Top-Up

Ordering your full winter supply in advance (typically during late summer or early autumn) is almost always more cost-effective than buying smaller net bags ad-hoc during winter. If storage is tight, many customers opt for a hybrid strategy: buying 2 bulk bags for the core winter months and topping up with individual log nets as needed.
