The lease must be signed by all tenants and your landlord. If there are common tenants, each tenant should receive a copy of the agreement. For example, the tenancy conditions are those that “mean that under the common law, a tenant can make the necessary repairs on the property and then “bleat” the associated costs with their rents. A clause that limits that is unfair. The rules for abusive clauses differ slightly depending on when your contract started. If the contract commenced before October 1, 2015, the contract will be reviewed pursuant to unfair clauses of the Consumer Contracts Regulations 1999. Clauses negotiated individually between two parties cannot be unfair under these rules, so not all the terms you and the owner have added to the basic contract are verified by commercial standards. The essential terms of the lease (the conditions under which the rent, the details of the property and the duration of the lease are fixed) must not be fair as long as they are “transparent” – as above, this means that they must be in clear and understandable language.  They may, however, be questioned in respect of aspects that do not concern matters that concern the substance of the treaty. For example, the concept of rent setting cannot be unfair simply because it sets a higher rent than other landlords, but it may be unfair because of the nature and date of the rent payment. The landlord is not allowed to enter the property and belonged to the tenant instead of unpaid rent. A term that allows it would be unfair.
A less ruthless owner may contain unfair clauses that know they are probably undated. If the tenant does not have time to lose abusive conditions or is unwilling to challenge them, the landlord will likely follow his own path. The lease you have depends on the facts of your situation, not what your agreement says. For example, if you pay rent to a private landlord who does not live with you and you have accepted a rent of 6 months, you will probably have short-term rent (or a guaranteed short rent in Scotland). This will also be the case if your agreement says otherwise. Check the type of lease you have. In summary, the regulations state that the consumer is not bound by an “unfair” clause in a contract with a supplier. You may also have signed an agreement that the property was granted under an occupancy licence. That is not enough to make the agreement a license. If you feel that your rental agreement may contain abusive conditions, you can go to your nearest citizen council.
All the terms of a written lease must be “transparent,” i.e. they must be in clear and understandable language. Any written term should be interpreted in a way that is favourable to the tenant if its meaning is not clear.  The lease is a form of consumer contract and, as such, must be done in clear and easy-to-understand language. It must not contain clauses that could be “unfair.”
