A commercial lease is a contract. The contract has terms, which govern the relationship between the parties to the contract and the rights they might have against each other or over the leased property. It may also be governed by legislation. In some rarer cases, you might be allowed to break the contract early at law due to a breach of the contract by the other side.

Thus, whether you can break a contract early depends on:

1. whether there is a contractual term in the lease allowing you to do so;

2. whether any relevant legislation applies allowing you to do so; and

3. what both you and the other party to the contract have done in the course of the lease.

I would suggest that you take the lease that you have executed to a solicitor or barrister so they can advise you of your rights under the contract and at law generally. If you do not have the right to break early and you do so, or if you do so incorrectly, you may be liable for damages to the other party under the lease.
