Internet or phone? The choice of the old generation. There was a time when it was one or the other, but now with DSL (digital subscriber line) it's a decision that is in the dustbin of the past. For a continuous digital connection with the consistent bandwidth not available through broadband, this tried and trusted technology suits.
DSL Internet Prices for the typical consumer vary substantially running up to £30 a month but they do come with the benefit of having a constantly connected phone line. Some plans include substantial download limits, and a speed that competes with broadband even on a good day.
If you find a good supplier, take into account that getting setup will require a visit to your home from a professional. A good supplier will know the day and the time that they will be in your area; they will have a firm notion of the amount of time it takes for them to make home connections. Therefore you can avoid having to take the entire day off work in waiting for the DSL service provider to arrive by communicating well from the outset.
A DSL connection requires no change to the infrastructure of your home, using the existing copper wire of your phone line, the addition of special hardware is the only change. Once in place you can look forward to download speeds of up to 8 megabytes per second.
