The instructions for the leases of October 1, 2015 are: A term may be considered unfair if it is difficult for a layperson to understand or when he does not use simple language that is easy to understand. If it turns out that a term is unfair, it does not insert the entire contract, but only the clause itself, which becomes unenforceable. Under the Consumer Rights Act, the definition of an abusive clause remains the same as under the unfair clauses contained in the contracts with consumers in 1999. Contact trading standards if you feel that some of the terms of your lease are unfair. Trading standards can verify the contract and may ask the owner or agent to remove some of the conditions. If the rental agreement contains a rental price verification clause, the tenant has already agreed to increase. However, they must be fair. If the rental agreement is not a barrier to the rental, the landlord can still ask for a rent increase. However, the tenant can refuse, and the only action the lessor can take is to terminate the lease by focusing the tenant with the exit. In summary, the regulations state that the consumer is not bound by an “unfair” clause in a contract with a supplier. The tenant is entitled to “exclusive ownership” and the “quiet enjoyment” of the premises during the rent.
Other fees and penalties, such as administrative and excessive insurance costs, are unfair. 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. “Establishment” means that under the common law, a tenant can make the necessary repairs to the property and then “bleat” the associated costs with his rents. A clause that limits that is unfair. A concept is unfair when it creates a significant imbalance of rights and obligations between a “trader” and a “consumer” to the detriment of the consumer. An unfair clause in a tenancy agreement is a clause that creates such an imbalance between the landlord and the tenant to the detriment of the tenant. The fairness or nullity of a clause can only be assessed in the context of all the circumstances associated with the agreement.  One form of words that is considered acceptable in one agreement is not necessarily fair in another.
Only a court can decide what is right or wrong in a particular case. 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.  There is nothing to prevent the inclusion of abusive clauses in a lease agreement, but an owner must be aware that just because it is included does not mean that it is not applicable. Any clause in a consumer contract must be fair. This rule also applies to leases. The Consumer Rights Act 2015 and the Terms Unfair in Consumer Contracts Regulations 1999 explain the types of clauses that can be considered abusive. The regulations apply only to standard terms and not to individually negotiated terms.  Nor does they apply to a clause in a lease agreement that is prescribed by law.  Include all the terms in the main document.
