I would love a unit that was heated free, held 10 vans, rates of £100 a month, not going to happen, and understand the dont get bigger than you need as rates are based on size I found that out by default..
But how did you find your unit Rob, mine came from an commercial estate agent as I could not see anything in the papers in the area unit is in, Yours at £300 a month IMP is cheap if you are storing 4 vans in there and is duplex, are your paying rates included as my rates are near enough half your rent a year.
