British Airways Flight Cancellation on 26 May 2023 causing delay by 7 hours

Flyer_Novice

Our return trip from Sydney Australia to Manchester international airport  was delayed by over 7 hours.

Flight was booked with BA. 
Departed from Sydney on time 25 May 2023 at 2.15 pm. Flight was as arranged by BA, with BA  from Sydney->Hong Kong->London Heathrow-> Manchester (expected to arrive at 10 am on 26 May 2023.
The flight from LHR to Manchester on 26 May 2023 at 8.55 am was cancelled due to IT issues.
We were arranged for an alternative BA flight to leave at 2.15 pm but got delayed to depart at 4.26 p. 26 May 2023.
we arrived at Manchester International Air Port at 5 pm on 26 May 2023- delayed by 7 hours.

Are we eligible for a compensation under EC Regulation 261/2004 that has been written into UK law?

Thanking you in advance for your advice

Yes IT failures are entirely the fault of BA but I suspect they will only offer compensation based on the domestic flight which would be £220 each, not the £52o which would be due if the entire route was on BA but since they do not fly from SYD to HKG I assume you began the route on Cathay Pacific and being a non-EU airline they will argue that is not the beginning of the route for compensation purposes

The flight from the Sydney to HK was on a Cathy Pacific Carrier. I gather few airlines pool Such as BA,Cathy Pasific,AA ect
The boarding pass has Flight Sold as BA 4130.
Does that has any implications I wonder?

The Flight from HK to LHR was on a BA carrier by the way?

Codeshares are irrelevant, it is the actual carrier that matters. I think they will try and argue your starting flight was not on an EU airline and not from an EU airport, but as BA were the carrier from HK, you might want to argue that you were on a flight from HK to Manchester in the hope of getting the higher level of compensation

Mm...
Let us then contact BA for the cancellation and the delay.
Our booking was with British Airways.
BA booked our outward journey on BA Carrier from Manchester to Sydney through LHR & Singapore(two BA carriers)
And our return journey as the was as I mentioned above.

It is the operating carrier of the flight that caused the delay that you claim from, irrespective of where you purchased it or if it was a codeshare with another carrier. eg If your delay had been started in Sydney then there would be no compensation due (as Cathay would be the responsible party - non-EU carrier, departing outside EU)
I believe in the past they have paid the shorthaul compensation level when it has been the cause of the delay
