As a general rule, you can in principle do this and there's some helpful VM staff here who'll respond in due course about this.
Just as a word of caution, it is very expensive if VM need to extend the network with new trench and ducting. If you use a guide figure of £200 per metre, and then work out the distance to the nearest VM cabinet (under council owned roads or footpath) you'll probably get a fair idea. I'm guessing that there's many tens of metres and the likely cost will be more than you want to pay.
If sufficient people in your road will commit to ordering, then potentially VM will swallow the network extension costs themselves. If multiple people want VM, but the company won't extend the network at their own cost, you might be able to club together and make a joint payment (this isn't totally unheard of, but tends to be complicated and rare).
