Don't worry, this is not about TalkTalk or PlusNet. Although on paper they're the cheapest, their recent reviews don't seem very encouraging -- which means more cost in terms of breaking your contract and paying for the start up costs of another provider.
The following two providers, in effect, end up being the cheapest providers you can actually buy your Internet services from:
O2: Customer reviews about them are good, and except for issues with their download limits, the overall response seems pretty good.
Their cheapest plan comes with a cost of £08.00 for a 20 Mbps plan and a 20 GB data limit, which is great value for money. Of course, for those looking forward to a lot of P2P action, this may not be an ideal solution.
Tesco: Again, their cheapest plan comes with a cost of £08.00 for a 20 Mbps plan, but with one major distinction: unlimited data usage.
On the downside, they have an 18 month-long contract as opposed to 12 months that most providers have.

You probably already know that, don't you? However, there are some daring fellows out there who choose to do things that most people do not recommend. For example, going ahead with a cheap Internet provider despite negative reviews about service or speeds.
If you are one of those, please do yourself a favour and beware of at least the following providers:
NewNet: They do have a £07.99 with bandwidth claims of 24 Mbps. However, their monthly data usage is just 3 GB. Do you think that's a lot of data? Wait till your PC discovers some random virus that hogs your bandwidth and adds thousands of Megabytes to your data transfer on a weekly basis.
Moreover, if you can find yourself a good unlimited plan for nearly £8.00 with a 20 Mbps download capacity, why would you want to limit yourself to a mere 3 GB?
Fast4: Their cheapest plan stands at £09.98, however, their data limit is just 1 GB. I wouldn't touch it with a ten-foot pole. Their reviews don't seem very positive either.
