From your link it states:
FIRE TRUCK
On an unlicensed airfield there is not normally a requirement to have any fire fighting and rescue equipment. However, it is strongly suggested that some sort of truck containing fire fighting equipment, rescue equipment and first aid kit is available. A list of actions in the event of an accident should also be kept in that vehicle. Immediate communications with the emergency services should always be available, so make sure the airfield mobile phone is charged and on the ground where it’s needed. If your club has such a vehicle or facility, please ensure that it is actually available for immediate use. Murphy’s Law says the truck is stuck in the back of the hangar just when it is needed!

PS. I had a retireve at my airfield last night by a glider from Lasham. We stood up fire cover and the tug lifted after normal hours to take him home. I'm all for the gliding movement and do not have an axe to grind.
