Report Unsafe Property Conditions - London Bylaws

Public Safety England 4 Minutes Read · published February 02, 2026 Flag of England

In London, England, unsafe property conditions that present an immediate risk to health or safety are handled by local authorities through housing, environmental health and building-control powers. This guide explains how hazards are assessed, who enforces standards, common notices and the practical steps for reporting dangerous structures or poor housing conditions to your local council.

What counts as an unsafe property condition

Local authorities assess hazards using the Housing Health and Safety Rating System (HHSRS) framework and building-control powers for dangerous structures; a hazard may include severe damp and mould, structural collapse risk, exposed electrical faults, unsecured façades, or serious fire-safety defects.

Penalties & Enforcement

Enforcement powers derive from housing and building legislation that allows local authorities to issue improvement notices, prohibition orders, hazard awareness notices and, where necessary, to undertake emergency remedial works or demolition. The principal statutory framework is the Housing Act 2004 and related building-control provisions Housing Act 2004[1].

If a property poses an immediate danger, call emergency services and report to your council immediately.
  • Common non-monetary orders: improvement notices, prohibition notices, emergency remedial action and works in default.
  • Prosecution in the magistrates' court or civil recovery of costs where councils act in default.
  • Fine amounts: not specified on the cited page for standard penalty levels; see the primary legislation for specific offences and penalties Housing Act 2004[1].
  • Escalation: councils may move from advisory notices to formal notices, then prosecution or works in default for continuing breaches; precise escalation ranges are not specified on the cited page.

Enforcer: the local authority's Environmental Health, Housing Enforcement or Building Control team is the responsible officer for assessing and enforcing unsafe conditions. To find and contact your local council to report an unsafe property, use the official GOV.UK local council finder and your council's environmental health or building-control contact pages Find your local council[2].

Applications & Forms

There is no single national “unsafe property” form; most London boroughs provide online complaint or reporting forms for housing or building-control hazards. Use your local council's environmental-health or building-control report form linked from the local authority site; where a council form is not published, telephone or email contact is normally provided on the council page Find your local council[2].

How enforcement is carried out

  • Inspection: an officer will inspect (or refuse if immediate risk requires emergency action).
  • Risk assessment: officers apply HHSRS principles for housing-related hazards and building-control checks for structural issues.
  • Notice served: improvement or prohibition notices set required remedial actions and timescales.
  • Works in default: councils may carry out remedial work and recover costs from the owner.
  • Prosecution or civil proceedings where owners fail to comply with notices.
Keep dated photographs and copies of correspondence to support any complaint or legal action.

Common violations and typical outcomes

  • Severe damp and mould leading to health risks — often leads to improvement notice and remedial works.
  • Unsafe electrics or gas — may lead to prohibition of use until certified safe and immediate enforcement action.
  • Structural defects and unstable façades — building-control action or emergency works; demolition in extreme cases.
  • Fire-safety failings in HMOs — prohibition orders, licensing compliance requirements and possible prosecution.

Action steps

  • Report the hazard to your local council's environmental health or building-control team via their online form or telephone line.
  • Provide evidence: photos, dates, addresses, contact details for the owner/agent and details of hazard impacts.
  • Follow up: note inspection dates and any notices served, and respond promptly to council requests.
  • If dissatisfied, use the council complaints process and consider appeal routes identified in the notice or seek legal advice.
