The details of the delay look like one where compensation should be due - regardless of that, you are entitled to reimbusement of the GBP110 incurred due to the delay
At this stage I would either start a claim against the airline or pass it to one of the companies that will recover any owed EC261 compensation for a percentage fee
Neother where ticket was issued nor that it iwas an award ticket have any impact on EC261 delay/cancellation compensation
