I can't say whether what you are experiencing is normal or abnornmal. However it's certainly not good.
Moving you to the 10meg service has placed you into a different tier of users. Inevitably more use of the net is made at peak times (when the schoolkids get home, etc). As all broadband, cable and ADSL is to some extent contended, other users use will impact on you.
Simple answer, you are on a trial. If the service don't work for you at the trial level, phone Telewest and ask to be downgraded, saying you don't want the trial or upgrade - you can tell them why. At least you save the upgraded service cost for the future.
