You offer the same service with the EEA Family Permit. A Filipina married to a E.U. Citizen that want to vist UK have to request it at the nearest British Embassy and they will be granted with a 1 year EEA Family Permit that allow her to go there with her Husband.
I never say Filipinos Citizen do not need a visa, they need it. But overstaying is less a probelm when married with a Brit as he has the right to stay in France as a European Citizen. And this will help his wife to get a residency card (this is mandatory for all non E.U. citizen).
