Do you really need to change? If your speed is that low, there's probably something wrong on the line or in the exchange. Last week I helped a neighbour whose download speed was down to 0.18 (yes, really). In a rural area, but should get around 2.5. I spoke to India (got through in 2mins). Very pleasant man answered (good English) and accepted that there was something amiss. Openreach arrived 4 days later (after 3 appointments that they didn't arrive for) and after a couple of hours work found a problem with a joint on one of the poles. Speed now around the 3Meg mark.
