Lots of peoploe commuting down to London from our town - Bicester - as it is on the main track from London Marylebone to Birmingham and reasonably short journey about 1hr to 1 1/2 hours (depends on the train type).
Or you can try to take a look aroun the towns like High Wycombe or Princess Risborough etc. on the same line - they are even closer to London...
Not sure about Filipino population there though...
