Hi, nparker, There are several routes you can take to finding out about allotments in your area. The first one is, you can look on-line to your local authority web site and they will have a section that covers allotments. There you should find out where the allotment sites are in your area. There will also be the name of the allotment officer and his contact numbers so you can give him a ring and find out what he can offer you. Some allotments are self-managed so if you find a possible site you could go to visit it and they should have a Notice Board with the Secretary's contact number on.
It is good to take a look around a few so you can judge if the facilities or the site is a good one and what you can expect. It is becoming increasingly difficult to walk straight into renting a plot as it is such a popular thing to do now, but you might be lucky. When I joined our waiting list three years ago there were only three people on it, so I only waited a couple of weeks.
We have a waiting list of thirty on ours now so people could wait six months to a year for the list to move up to the top, but each place is different. Good luck and I hope you can get one soon, it is a fantastic thing to have your own plot and so satisfying.
Bad luck for you Multi. There seems to be a horrible trend of allotments being taken over for housing etc. and they are fast becoming a very precious commodity. Lucky for you to have horse manure on tap.
