Just add up the total number of flights. Each flight is a sector in your example. As stated, a maximum of 16.
Surface segments also count, so in your itinerary EDI-LHR is counted as a sector even though it's not a flight. In your example you'd also need to count the return to your starting point NTL which makes 17 if my counting is accurate.
