I've created the following image showing the 800 layer (red) overlaid with the current LTE coverage (blue).
N.B. this is a big image - 23MB - so probably not mobile friendly!

That's an impressive piece of work - nicely done.
What it does show is how much coverage Three are hoping to claim from single cells. A great example of this is the High Hunsley site on the East Yorkshire wolds.
The 800mhz area takes in most of the city of Hull, large swathes of East Yorkshire, the towns of Beverley, Brough and Barton Upon Humber, and long stretches of the Humber Estuary. It's an absolutely vast area containing at least a couple of hundred thousand people.
One cell (at the moment at least).
5mhz.
Serving populations of 100,000's....
Do you see what I'm getting at??
I predict they're going to have to ration this very, very carefully. Whether that will be limiting the service to a very specific range of devices, or in speed caps, I don't know. I assume the VoLTE voice traffic will have to be prioritised to protect calls.
Also, the coverage level itself seems to be very optimistic - we're talking about a 15 mile radius, which, even with line of site, must be pushing it a bit. We all know how optimistic the 1800 mhz coverage is. That might be just about possible for data cards with external aerials, but for your average Samsung user, I think that's pushing it a bit. What's the maximum output power of a 4g cellphone? 1 watt?
It all seems very optimistic to me. So whilst people may see their 4g indicators light up, I'd be very surprised to see speeds at anything like the 4g we've been enjoying so far.
4g, but not as we (currently) know it.
