Under normal rules any vehicle that is being used to clear snow from public roads using a snow plough or similar device is entitled to use red diesel. However, only vehicles that are constructed or adapted and used solely for spreading material on roads to deal with frost, ice and snow can undertake gritting work while using red diesel.
HMRC recognises the vital role played by farmers in helping to keep rural roads clear and has recently consulted on a proposed change to the legislation to allow red diesel to be used in tractors while gritting. A summary of consultation responses will be published shortly. During periods of extreme weather, HMRC will adopt a pragmatic approach to the rules. This means that agricultural tractors on public roads clearing snow or gritting to provide access to schools, hospitals, a remote dwelling, or communities cut off by ice and snow can continue to use red diesel.
