rog_pete, that's quite an increase all in one go. If you're interested there may be grounds to challenge how soon they can impose the increase.
How much notice did the council give? What does your Tenancy Agreement say about the Council increasing the rent? Did the Council negotiate with your site association and offer any alternatives?
Dear TGU
I have finally dug out the Tenancy Agreement and found the clause in rent increase. It states "The Council reserve the right to review at any tie the yearly rent and to bring into effect the resultant revised charges after giving twelve months written notice thereof to the Association and the tenant"
Our allotment association has not informed me so at the moment I do not know if this 12 month written notice has been given. I shall be speaking to our Chair when I see him.
Initial assumption is that the Council have not complied with their terms, therefore the challenge may be a good thing to go down.
I feel the ranting is not finished yet!
