Here we’ve tried to include guidance on the general ongoing costs you need to bear in when buying a narrowboat.  We will go through this with you when you buy from Black Prince, ensuring you have everything covered.
Your basic costs will include your License fees, Mooring fees and maintenance such as winterization and your Boat Safety Certificate.  Your license is obtained from the relevant waterway authority, and the cost varies depending on where you want to cruise and how long you want to use it for.
Then you need to think about running costs, which will depend on how much time you plan on spending on board your boat.  These include fuel and gas, toilet pump out, water and maintenance.
