There are still a large number of airplane engineering jobs in the UK.
They are pretty well-paid and are relatively skilled jobs.
Just a few weeks ago, BA announced a multi-million pound investment in their widebody maintenance facility in Cardiff.
It currently just services 777 and 787 aircraft, but will be upgraded to also deal with A350s.
British Airways has announced a multi-million pound investment in its engineering maintenance facility at Cardiff Airport.

BA actually has a lot of workers in South Wales
You're right that they send their A380s to the Philippines, but the UK is obviously cost-effective enough for BA to continue to invest and expand its own maintenance facilities.
Battery powered aircraft exist and are operational, but I would question their usefulness given the very short range and the fact they can't leave the vicinity of the airport.

Commercial electric aircraft - even those with just 9 seats - are very far off. Several decades if ever.
While better for the environment (dependent on the electricity source and dependent on the impact of battery production), they are going to be just as loud as current aircraft as the propellers are the prime producer of noise.
