By law City of Edinburgh Council is allowed to set allotment rents at a "fair rent for the purpose" Allotments (Scotland) Act 1950
So how does the current rate of £100 per annum per allotment compare with the Scottish average for agricultural land?
The following link is to the Scottish Government. As they say: "The figures released today were produced by independent statistical staff, free from any political interference, in accordance with professional standards set out in the Code of Practice for Official Statistics."
Scottish Government Statistics
It states that the average rent for agricultural land was £38 per hectare in 2013.
60 standard Edinburgh allotments (of 60ft by 30ft each) make up one hectare (107,639 square feet).
So the Council is charging Edinburgh Allotment holders at a rate of £6,000 per hectare. That's a lot more than £38
The proposal to triple the rent will make it even more unreasonable!
