Wales Occupation Contract Term Variation, Break Clauses and Rent Increases

How Term Variation Works

Varying the terms of a Wales occupation contract is not a simple matter of issuing a new document. The Renting Homes (Wales) Act 2016 establishes different procedures depending on which type of term is being changed:

• Fundamental terms can only be varied in accordance with statutory procedures. Unalterable fundamental terms (F) cannot be changed at all. Alterable fundamental terms (F+) can only be modified if the change improves the contract-holder's position.
• Supplementary and additional terms can be varied by written agreement between the landlord and contract-holder.
• Rent has its own specific variation mechanism under Section 123.

After any variation takes effect, Section 32 requires the landlord to provide a written statement of the varied terms — or a full replacement written statement — within 14 days.

Rent Increases Under Section 123

Rent under a periodic standard occupation contract can only be increased by serving Form RHW12 (Notice of Variation of Rent). The statutory rules are:

• Notice period — at least two months' notice before the increase takes effect.
• Frequency cap — rent cannot be increased more than once in any 12-month period.
• Form — the increase must be notified using the prescribed Form RHW12. An informal email or letter stating a rent increase does not satisfy the statutory requirement.

If the contract-holder disagrees with the proposed increase, they can apply to the Residential Property Tribunal Wales (RPTW) for a determination. The tribunal will set the rent at what it considers the market rate for the dwelling — which may be higher, lower or the same as the proposed increase.

The Section 123 and Form RHW12 procedure applies to periodic standard contracts. For a fixed-term contract, check the written statement for any agreed rent-review term before changing the rent.

Break Clauses

A break clause is a negotiated additional term. A contract-holder's break clause can end a fixed-term contract early with at least four weeks' notice. A landlord's break clause is permitted only in a fixed term of 2 years or more; the landlord cannot serve notice under it before month 18 and must give at least 6 months' notice.

Any break clause must be included as an additional term in the written statement and comply with Consumer Rights Act 2015 fairness standards.

In practice, break clauses in Wales are less common than they were under the AST regime, because the automatic transition from fixed-term to periodic at the end of the term gives both parties a natural exit point.

Anti-Social Behaviour Clauses

Section 55 of the Act includes an unalterable fundamental term (F) prohibiting the contract-holder, and anyone living in or visiting the dwelling, from engaging in anti-social behaviour. This provision is automatically part of every standard occupation contract — a landlord does not need to add it.

However, a landlord can include additional terms that define specific behavioural expectations for the property, provided they do not conflict with any fundamental term:

• Noise restrictions — specifying quiet hours or limits on noise that affects neighbouring properties.
• Communal area rules — for flats or shared buildings, rules about use of shared spaces, refuse disposal and parking.
• Smoking restrictions — prohibiting smoking inside the dwelling or in specified areas.

These additional terms give the landlord a contractual basis for addressing behaviour that falls short of the statutory anti-social behaviour threshold but still causes management problems.

If the contract-holder breaches the Section 55 anti-social behaviour term, the landlord can serve a notice seeking possession on breach grounds — with a shorter notice period than the six months required for no-fault notices.

The Variation Process in Practice

When varying any term:

1. Identify which category the term falls into (fundamental, supplementary, or additional).
2. Confirm the variation is legally permitted — you cannot weaken an unalterable fundamental term.
3. For supplementary and additional terms, obtain written agreement from the contract-holder.
4. For rent, serve Form RHW12 with at least two months' notice.
5. Issue a written statement of the varied terms within 14 days of the variation taking effect.
6. Keep a copy of the variation document and the delivery evidence.
