We sell coal and peat in 20kg plastic bags because of 3 main reasons.
1/ A 20 kg bag is the most weight which can be lifted by any person in the UK. This has been made law from the EU.
2/ As you know either of the fuels can make a dirty, dusty mess on you or your furniture/carpets, so we deliver any these fuels, in a fully contained separate plastic bag.
3/ You can order any amount you want, Which will come to you at the correct weight IE: 60 kg = 3 bags
