Louis, there is no new embassy in Cebu.
But there is a new VFS Visa centre just opened there October 4th
VFS are the official visa admin partner for UKBA and thats where visa applications are made.

Take a look here for address, contacts and operational details of the new VFS centre in Cebu

For the UKBA fees take a look here

You can see that Settlement Visa is currently £826
This equates to P57820 at the current consular rate of £1 = P70

I suggest you contact the local VFS at the above link just prior to your application as the Consular Exchange Rate does change from time to time

Hope that helps
