You should always know when your contract is due to finish as that is the time to start looking for a new broadband deal. If in doubt either telephone your broadband supplier or log into your account on your ISPs website. Generally speaking, the length of a broadband contract is normally 12, 18, or 24 months and both the length and cost of deals can vary between providers considerably. It is worth looking at the complete package including offers and one-off packages that frequently are time-limited to bolster sales. Early termination fees are also worth investigating as they can be expensive, especially if you live in a short term rental.
