Parking space in a yard or farm around Northampton

Small haulage company looking to rent a parking space long-term in a yard or farm to operate an HGV unit and trailer. The vehicle is kept roadworthy, taxed and insured at all times and will be out on the road most of the time during the week. We will need access 24/7 if possible, please. Usually, the truck will be parked up in there on weekends.

Preferably in Northampton area. Could consider Northamptonshire as well, depends on location/postcode. I am open to offers.

Thanks in advance
