i think ntl has just 25% penetration in London (compared to 55% in teeside).
out of 545,000 households (i swear there's more than that in london!!)
so there's just 136,250 customers. i'm sure there are more.
probably the areas that cost more that £1,000 to upgrade are left out!
but, who knows, maybe ntl will do something. maybe we've underestimated ntl...
