Housing Disrepair Expert Witness in London
Housing disrepair claims turn on objective evidence of condition: what is defective, what caused it, and what it will cost to put right. Wimbledon Surveyors provides independent expert reports for disrepair claims across London — for tenants, landlords and housing providers. Discuss your case.
Independent Condition Evidence
We inspect and document damp, mould, structural defects, failed heating and other disrepair with photographs and measurements, distinguishing genuine disrepair from lifestyle condensation and tenant damage.
HHSRS Hazard Assessment
Where relevant we assess hazards under the Housing Health and Safety Rating System, addressing the standards housing conditions claims are judged against.
Cause, Liability and Cost
Our reports identify the cause of each defect, whose obligation it engages under the tenancy, and the reasonable cost of remedy — the three pillars of any disrepair claim.
Acting for Tenants and Landlords
We accept single joint expert and party instructions from either side. Social landlords also use our stock condition surveys to prevent claims arising at all.

Housing Disrepair Expert Witness Surveyors
Housing disrepair claims have grown sharply as tenants enforce their rights to safe, well-maintained homes — and as landlords defend claims that are sometimes exaggerated or misdirected. The evidence at the centre of every claim is a surveyor’s report: what disrepair exists, what caused it, whether it falls within the landlord’s repairing obligations, and what it will cost to put right. We provide that evidence for tenants, landlords, housing associations and solicitors across London and Essex, to CPR Part 35 standard.
The Legal Framework We Report Against
Our reports address the obligations that actually decide these claims: Section 11 of the Landlord and Tenant Act 1985 (structure, exterior and installations), the fitness for human habitation requirements inserted by the Homes (Fitness for Human Habitation) Act 2018, the Housing Health and Safety Rating System (HHSRS) hazard categories, and Awaab’s Law timescales for social landlords dealing with damp and mould. A defect only founds a claim if it engages these duties and the landlord had notice — distinctions our reports make explicit.
What Our Inspection Covers
- Damp and mould diagnosis — distinguishing rising damp, penetrating damp, plumbing leaks and condensation, because cause determines liability (see our damp survey expertise).
- Structure and exterior — roofs, walls, windows, gutters and the defects that let water in.
- Installations — heating, hot water, electrics and sanitation in disrepair.
- HHSRS hazard assessment — categorising hazards to health the way environmental health officers do.
- Schedule of works and costings — the remedial scope, priced, with a realistic programme.
- Notice and history — reviewing the complaint trail, because liability generally runs from notice.
Balanced Evidence, Whoever Instructs Us
Acting for tenants, we document genuine disrepair thoroughly — photographs, moisture readings, hazard categorisation — so claims are neither dismissed nor undervalued. Acting for landlords, we distinguish disrepair from condensation caused by lifestyle factors, from improvements outside the covenants, and from damage — and we say plainly when a claim is well-founded. That balance is what Part 35 requires and what makes reports persuasive in negotiation and at trial. Single Joint Expert appointments are welcomed.
Instructing Us
Solicitors typically instruct us under the Pre-Action Protocol for Housing Condition Claims, which encourages a single joint expert and sets report timescales. Send the letter of claim, tenancy details and complaint history, and we will confirm timescales and a fixed fee. Related services: expert witness practice, damp surveys and building surveys.
Frequently Asked Questions
Defects the landlord is obliged to remedy — typically the structure and exterior, plus installations for heating, water, gas, electricity and sanitation under Section 11 of the Landlord and Tenant Act 1985, and anything rendering the home unfit for habitation under the 2018 Act. Cosmetic wear and tenant damage generally are not disrepair.
It depends on the cause. Rising damp, penetrating damp and leaking installations usually engage the landlord’s obligations; condensation mould can too where it stems from the building’s design or defects, particularly under fitness-for-habitation duties. Expert diagnosis of the cause is usually the decisive evidence.
The Housing Health and Safety Rating System scores hazards in the home — damp and mould, excess cold, falls, electrical risks and others — as environmental health officers do. Category 1 hazards oblige councils to act, and HHSRS categorisation strengthens condition evidence in disrepair claims.
Generally yes — liability for disrepair within the property usually runs from when the landlord had notice and a reasonable time to repair. The complaint history is therefore central evidence, and our reports review it alongside the physical findings.
Under the Housing Conditions Protocol the parties are encouraged to instruct a single joint expert with fees usually shared, though arrangements vary and successful claimants commonly recover costs. We confirm fees and instruction terms with the solicitors at the outset.
