Mobile data is not really used as a home broadband replacement in the UK.
Generally you will get a few GB of mobile data, and use WiFi at home, provided over a BT or virginmedia cable line.
So you should be looking at things such as BT Infinity, TalkTalk Fibre, Sky Fibre, Virginmedia, PlusNet Fibre instead. Unless for whatever reason they cannot get anything decent over a fixed line.
Most deals are unlimited.
Also you think our prices are expensive, but the US and various EU countries are more pricey.
Just adding to brandscill's post here...
Also it is generally not appropriate in the UK to use mobile data for a home broadband connection, some have done it over network 3, but the mileage and results vary massively and generally it is not advised.
