When buying logs its worth knowing that a large majority of the kiln dried firewood in the U.K comes from eastern Europe. Shipped thousands of miles to the U.K and distributed nationwide by large suppliers this type of firewood has such a large carbon footprint it far negates the positives of burning such wood.
If Logs are sold neatly stacked in a crate (its more cost-effective shipping stacked logs) they are from Eastern Europe. There are many suppliers of high quality locally sourced firewood within the U.K, promoting local jobs and sustainable forestry practices. Please buy local and if in doubt ask your supplier where there wood is sourced.
