Homeplug and Two Independent Mains Circuit

[j05e]

I've just converted two semi-detached houses into one. House A has the Virgin superhub and several homeplugs. Is it possible to connect the two mains circuit with a pair of homeplugs so I can use homeplugs in house B?

How many fuse boxes / consumer units are there? If everything is running off a single board then homeplugs should work anywhere in the property, albeit a bit slower than if they were all on the same ring main.

If there are multiple boards then you'd need to bridge between the properties using cat5 or wireless.
