Disrepair as a Rent-Tribunal Factor: How Poor Condition Cuts the Market Rent

The Valuation Principle

Section 14(1) of the Housing Act 1988 tells the tribunal to determine the rent at which the property "might reasonably be expected to be let in the open market by a willing landlord under an assured tenancy" with the same rent periods and, apart from the rent, the same terms as your tenancy. Section 14(2) then lists three things the tribunal must disregard: any effect on the rent of granting a tenancy to a sitting tenant; any increase in value from qualifying improvements the tenant carried out (other than under an obligation to the landlord); and any fall in value caused by the tenant's failure to comply with the tenancy terms.

None of those disregards covers the landlord's failure to repair. Form 4A itself tells tenants that "the tribunal can consider other factors like the condition of the property when deciding what the rent for your home should be" (Form 4A (05.26), section 5.2).

This is why condition evidence matters in a rent-tribunal challenge: a willing tenant would pay less for a property in poor condition.

What "Condition" Means at Tribunal

Condition evidence can cover:

• Visible disrepair. Cracked plaster, leaking ceilings, damaged flooring, broken windows
• Damp and mould. Often a serious factor, both for health and for value
• Heating. No heating, inadequate heating, or storage heaters in a property that should have central heating
• Hot water. Intermittent or inadequate hot water provision
• Insulation. Single glazing, draughts, cold bridging, poor EPC rating
• Kitchen. Dated, damaged, or inadequately equipped kitchen
• Bathroom. Dated suite, ineffective shower, damaged seal or grouting
• Electrics. Pre-RCD consumer unit, sockets in disrepair, lighting issues
• Pests. Active infestation, signs of recent infestation
• External features. Damaged garden, broken garden walls, poor entrance access
• Common parts. Damaged stairwells, missing handrails, broken communal lighting

The Wider Legal Standards

Condition also matters under other laws, separately from the rent determination:

1. Section 11 of the Landlord and Tenant Act 1985 — the landlord's implied covenant to keep in repair the structure and exterior, and to keep in repair and proper working order the installations for water, gas, electricity, sanitation, space heating and heating water.
2. Section 9A of the Landlord and Tenant Act 1985 (inserted by the Homes (Fitness for Human Habitation) Act 2018) — the landlord must ensure the home is fit for human habitation at the start of the tenancy and throughout it.
3. The Decent Homes Standard and Awaab's Law — the Renters' Rights Act 2025 contains powers to apply a Decent Homes Standard and hazard-repair timescales ('Awaab's Law') to private rented homes, but these depend on regulations and are not yet in force for private tenancies. The Government's policy statement of 28 January 2026 says the new Decent Homes Standard will apply to private rented homes from 2035.

The tribunal's question under section 14 is still the market rent. A breach of these standards is relevant because of its effect on the property's condition, and so on what a willing tenant would pay.

How Much Difference Does Condition Make?

There is no fixed tariff. The tribunal decides each case on the comparable evidence, the condition evidence and, where it inspects, what it sees. Published Property Chamber decisions, including market-rent cases, are searchable on GOV.UK ('Residential property tribunal decisions').

What Each Side Should Do

The Tenant

If condition is in play, build the evidence:

• Dated photographs. Use a phone camera with the date stamp enabled, or take screenshots with metadata visible. Photograph each issue from multiple angles. Photograph the room as a whole, then the specific problem.
• Video walkthroughs. A two-minute video walking through the flat showing the issues is powerful evidence — much more so than a static photograph.
• Reports. If you have an Environmental Health report (from a council inspection under HHSRS), an independent surveyor's report, or a contractor's quote for remedial works, all of these are useful.
• Correspondence. Every email, text, or letter you have sent the landlord about repairs, and their response (or lack of response).
• Medical evidence. If the disrepair has affected your health — typically damp causing respiratory problems — a GP letter or hospital record is significant evidence.
• A timeline of reports. Record each time you reported a problem and the landlord's response (or lack of response). The timeline supports your condition evidence and any separate disrepair claim.

Pull all of this into a "condition schedule" — a one-page table listing each issue, the date you first reported it, the landlord's response, the photograph reference, and the proposed impact on rent.

The Landlord

If you are serving Form 4A and the property has known issues:

• Fix what you can before serving. A property that has been brought up to standard before the Section 13 notice is worth more rent than one that has not. The order matters: repair first, then notice.
• Acknowledge what you cannot fix. A genuinely older kitchen, a flat with single glazing in a listed building — these are sometimes unavoidable. Reflect them in the rent figure. Asking for new-build money on a tired Victorian conversion is not credible.
• Document your repair record. If the tenant alleges disrepair the tribunal does not see, your repair log is your defence. Date of each request, date of each response, date of each contractor visit, photographs of completed works.
• Get a letting agent's view of the figure. An agent who has been into the flat and knows the area will give you a more grounded figure than a back-of-the-envelope calculation. The agent's letter is also useful at tribunal.

Repair first, then notice, applies on the statutory side too. Awaab's Law will put fixed timescales on investigating and fixing hazards in private rented homes once the Renters' Rights Act 2025 provisions are commenced, and a repair log that already meets them is the best answer to a condition schedule. ComplyWithMe's guide to Awaab's Law and private landlords sets out what applies now and what is coming, and its exposure check shows where a property stands from a postcode and a few answers.

The Tribunal's Inspection

The tribunal may inspect the property (rule 21, SI 2013/1169). It decides in each case whether an inspection or a hearing is needed, or whether it can decide on the papers, and it may also use online resources to look at the property (GOV.UK, 'Apply for an open market rent determination').

If the tribunal inspects:

• It must give reasonable written notice of the date and time (rule 21(3))
• Entry depends on the necessary consents (rule 21(2))
• It may ask for the parties to accompany it (rule 21(4))

For the tenant, an inspection is usually helpful — the panel sees the issues first-hand rather than relying on photographs that may be challenged as unrepresentative. For the landlord, the inspection is a moment of truth: the property speaks for itself.

Two Worked Examples

Example 1 — Modest disrepair, moderate discount.

A two-bedroom flat in north London. Current rent £1,800. Landlord proposes £2,100 (17% increase). Comparable evidence suggests the market for similar properties in good condition is around £2,050.

But the subject property has: single glazing throughout (zone-3 conversion flat where most comparables have been retrofitted with double-glazing), a 2007-vintage kitchen with worn worktops and a dishwasher that no longer drains, and a tired bathroom with visible mould around the shower seal.

Suppose the tribunal finds that the flat's condition puts its open-market rent at about £1,900, some 7% below the £2,050 for comparable flats in good condition. Because that is lower than the proposed £2,100, it sets £1,900 (s.14ZB(5)), £200 a month less than the landlord proposed. The figures are illustrative; every case turns on its own evidence.

Example 2 — Serious disrepair, large discount.

A one-bedroom flat in south London. Current rent £1,400. Landlord proposes £1,650. Comparable evidence suggests £1,550 for similar properties in good condition.

But the subject property has: serious damp in the bedroom (visible black mould, GP letter from the tenant about respiratory issues), a non-functioning heating system (the boiler has been broken since February 2026; the tenant has been using portable heaters), and a kitchen sink that drains very slowly because of a partial blockage the landlord has refused to address.

Suppose the tribunal finds that, in its actual condition, the flat's open-market rent is £1,250. Because that is lower than the proposed £1,650, the new rent is £1,250 (Housing Act 1988 s.14ZB(5), inserted by the Renters' Rights Act 2025). There is no floor at the existing rent, so the tribunal can set a rent below the current £1,400. The figures are illustrative.

In Example 2, the tenant may also have a separate disrepair claim against the landlord (for example under section 11 or section 9A of the Landlord and Tenant Act 1985) and can ask the council's environmental health team to inspect under the Housing Health and Safety Rating System.

Cross-Linking to Disrepair Claims

A rent-tribunal application is not the same as a disrepair claim, but the two interact.

If the property is in serious disrepair, the tenant has three potential routes:

1. Rent-tribunal application — to challenge a Form 4A and have the rent set below the proposed figure
2. Disrepair claim — under section 11 of the Landlord and Tenant Act 1985 and, for fitness for habitation, section 9A of that Act — for damages and an order for repairs
3. Local authority enforcement — through the council's environmental health team under the Housing Health and Safety Rating System (Housing Act 2004, Part 1)

The three are not mutually exclusive. A tenant in a Form 4A dispute with serious disrepair can run all three in parallel. The disrepair claim and the rent-tribunal application can support each other evidentially.

See our separate pieces on housing disrepair court bundles and Section 11 claims for the disrepair side of the picture.

What Not to Do

Tenants. Do not exaggerate. The tribunal may include a surveyor member, and it can inspect the property. Overstating the condition issues, photographing a single small patch and describing it as "covering the whole wall", or claiming repairs were never carried out when records show otherwise, will all backfire. Present an honest case.

Landlords. Do not try to airbrush condition. Refusing to acknowledge known issues, presenting only photographs from before defects developed, or commissioning surveyor reports that read like marketing brochures will all weaken your credibility. The tribunal may decide to inspect.

What to Put in the Tribunal Bundle

A condition-focused tribunal bundle should include:

• The Form 4A as served
• The tenancy agreement
• A schedule of comparables
• A condition schedule (one page summary)
• Dated photographs, in date order
• Any video evidence (check the tribunal's directions on how to send it)
• Environmental Health, surveyor, or contractor reports
• Correspondence between the parties about repairs
• Any GP letters or medical evidence relating to health impact
• A timeline of repair reports and the landlord's responses
• A brief witness statement

Follow any directions the tribunal gives about bundles (rule 6(3)(k), SI 2013/1169).
