Tenancy conditions

Tenancy conditions are the express and implied terms that define the rights and obligations of landlord and tenant under a private residential tenancy. Express conditions are those agreed in writing or verbally and recorded in the tenancy agreement. Implied conditions are imposed by statute or common law and form part of the contract whether or not they are written down, and cannot be excluded by the parties even where the agreement purports to remove them.

Express conditions

Express conditions cover everything the landlord and tenant have explicitly agreed. In a standard private tenancy, these will include the rent amount and payment date, the address of the property, the identity of all parties, the start date and tenancy type (from 1 May 2026, all new private tenancies must be assured periodic tenancies under the Renters' Rights Act), any deposit amount and the scheme used to protect it, rules on pets, smoking and subletting, the procedure for rent increases, and any obligations specific to the property such as garden maintenance or care of a boiler.

Express conditions must comply with the Tenant Fees Act 2019 on permitted payments and the tenancy deposit cap. Any express condition that attempts to increase the permitted deposit, charge a prohibited fee, or reduce the landlord's statutory repair obligations is void regardless of whether the tenant has signed the agreement.

Implied conditions

Implied conditions arise from statute and case law rather than from the written agreement. They bind both parties automatically. The most important for self-managing landlords are:

Landlord's repairing obligation. Under Section 11 of the Landlord and Tenant Act 1985, the landlord must keep the structure and exterior of the property in repair and maintain the installations for water, gas, electricity, sanitation, heating and hot water. This duty applies whether or not it appears in the agreement and cannot be excluded by any tenancy condition.

Fitness for human habitation. Under Section 9A of the Landlord and Tenant Act 1985, as extended by the Homes (Fitness for Human Habitation) Act 2018, the property must be fit for human habitation at the start of the tenancy and throughout. This is an implied condition enforceable directly by the tenant.

Quiet enjoyment. The landlord has an implied duty not to interfere with the tenant's right to occupy the property peaceably. Any condition permitting the landlord to enter without notice or to interfere with the tenant's use of the property will be unenforceable.

Tenant-like use. The tenant has an implied obligation to use the property in the way a reasonable tenant would, keeping it clean, not causing damage, and reporting necessary repairs.

From working with self-managing landlords across the UK, implied conditions are the category most often misunderstood. A landlord who believes their agreement has excluded a repairing obligation because it is silent on the subject has not excluded it, the statutory duty applies regardless.

Unfair conditions and the Consumer Rights Act 2015

Under the Consumer Rights Act 2015, any standard tenancy condition that creates a significant imbalance between the landlord and the tenant, contrary to the requirement of good faith and to the tenant's detriment, is unfair and unenforceable. The test applies to all conditions except the core terms, the rent, the property description, and the tenancy length, provided those core terms are written in plain and intelligible language.

Conditions that courts and the Competition and Markets Authority have treated as potentially unfair include: blanket professional cleaning requirements at the end of the tenancy regardless of condition at the start; clauses requiring tenants to replace old furnishings with new; penalty clauses that are disproportionate to the landlord's actual loss; and terms allowing the landlord to enter without the required minimum 24 hours' written notice.

Landlords should also note that unfair or unclear conditions can count against them at the Private Rented Sector Ombudsman and in possession proceedings. A possession claim can be undermined if the landlord cannot demonstrate that the tenancy conditions were lawful, clear and fair throughout.

Changing tenancy conditions

Tenancy conditions can normally only be changed with the agreement of both parties. Any agreed variation should be documented in writing, either a new tenancy agreement or a signed amendment letter. A landlord cannot unilaterally change conditions (for example, increasing the rent outside the statutory Section 13 process, or adding new rules mid-tenancy without consent). Under the Renters' Rights Act 2025, landlords must provide tenants with a written statement of tenancy terms; failure to do so can affect the ability to recover possession and may attract civil penalties.

August's document management feature lets landlords store the tenancy agreement, signed conditions, and any variation letters in one place, alongside safety certificates and compliance records.

Frequently asked questions

What is the difference between express and implied tenancy conditions?

Express conditions are those written into the tenancy agreement or agreed verbally between landlord and tenant. Implied conditions are imposed by statute or common law and apply automatically, whether or not they appear in the agreement. Implied conditions cannot be excluded, a clause in the agreement that tries to remove a statutory duty is void.

Can a landlord add new conditions to a tenancy mid-tenancy?

No, not without the tenant's agreement. Once a tenancy is in place, the conditions can only be changed by mutual consent. Any unilateral attempt by the landlord to impose new conditions, such as banning pets after the tenancy has started, or increasing the deposit, has no legal effect and could amount to harassment if pressure is applied to compel acceptance.

What makes a tenancy condition unfair under UK law?

Under the Consumer Rights Act 2015, a condition is unfair if it creates a significant imbalance between landlord and tenant, contrary to good faith and to the tenant's detriment. Practically, this means conditions that take away the tenant's legal rights, require the tenant to meet obligations the landlord would not, or impose disproportionate penalties. An unfair condition is unenforceable, it does not bind the tenant even if they signed the agreement.

Do tenancy conditions change under the Renters' Rights Act 2025?

Yes, in several respects. From 1 May 2026, all new private tenancies must be assured periodic tenancies, conditions tying the tenancy to a fixed end date are no longer permitted for new lets. Landlords must give tenants a written statement of terms. Conditions relating to deposit amounts and rent in advance are also affected. Landlords can only require one month's rent in advance for assured tenancies. Existing conditions that conflict with the new framework are overridden by statute.
