Domestic worker Visa

Hi,
We have a slightly complicated situation I hope someone can advise us on.
We are British and used to live in Singapore and employed a Filipino live in helper while we were there for over 1 year. We moved temporarily to Greece and couldn't get a domestic visa for our helper in Greece. We thought we'd only be in Greece 6 months and then be returning to Singapore so we left our helper in Singapore working with another family temporarily.

We are now advised we will instead be going back to the UK and would really love for our helper to come with us on a Domestic worker visa. Our problem is....We are for the moment still in Greece and she is in Singapore, so not living under the same roof at the time of applying.
Is there anyway to still apply for her visa under these conditions, given that we still have her contract etc. I don't want her to travel here and then her UK visa be refused as she is in Greece on a temporary visiting visa and if we apply online we have different addresses which of course will not meet the criteria.
Has anyone any ideas?
Thanks
