The arrangement fee is assumed to be paid upfront and not added to the mortgage. If added to the loan, interest would be charged on it for the remainder of the term.
Rule of thumb: Switching makes sense when the break-even period is shorter than your expected time on the new deal. The larger the rate difference and the lower the fees, the faster the break-even.
