I leave in a rural area and up until a week ago my speeds were 2 and 0.25 so you're doing we'll.
Our local exchange was upgrade a few weeks back and we've managed to get our speed upgraded not on 16 and 3. Key is distance from exchanged bad were luckily just under a mile from the last piece of fibre on the system.
Try the BT Openreach site and see if you can get a faster speed. As with everything in life it'll cost though.
