Rent increase

Got my letter from council saying that the rents going up on the allotment this year, last year it was £30.75 and included £5 water. This year it's £34.50 + £5 water so it's around £9 a plot extra,mine will be double with it being a double size. Not complaining i don't mind paying it,i get my money's worth of veg and peace and quiet.
