Hounslow Local Plan: adopted policies and emerging plans

Hounslow’s 2015 to 2030 Local Plan remains the adopted borough plan while the 2020 to 2041 replacement is examined. The latest examination update asks for post-hearing work by 18 September 2026; it is not an adoption notice.

London Borough of Hounslow, England

Review status
AI-assisted source check. Professional planning review not completed.

Check the planning authority first

Check Hounslow’s administrative boundary before using the borough plan. The West of Borough and Great West Corridor submission documents concern areas within Hounslow; they do not establish separate planning authorities.

The adopted-plan evidence library lists the London Plan and joint waste plan alongside the Hounslow plan. Relevant cross-boundary impacts still require checking for the individual site.

Adopted development-plan documents

Read the relevant policy wording and map together. An unverified date is a gap in this profile, not a finding that a document has no legal effect.

  • London Plan 2021

    Adopted. March 2021 strategic plan.

    London-wide strategic policies form part of the development plan. Read them with the relevant borough documents and any made neighbourhood plan.

Policies maps and site boundaries

ADP3 and ADP3a in the adopted-document library are the east and west policies maps for the 2015–2030 plan.

Do not substitute a proposed submission map or a suggested site-allocation modification for the adopted map. Use the appropriate east/west sheet and the policy text together.

Emerging plans and examination progress

The 16 July 2026 news entry publishes EX73, actions arising from hearings on 1–2 July. It says the requested updates are due to the Inspectors by 18 September.

The replacement plan was submitted on 23 June 2025. Check the news page and correspondence library for later modifications consultation, final report and adoption rather than treating the end of hearings as approval.

The West London Waste Plan replacement is a separate live Regulation 19 consultation, listed to close on 28 September 2026.

The 2015 adoption date is recorded in official indexed Council minutes; direct retrieval of that meeting page failed during this check. The adopted-document library remains accessible.

  • Hounslow Local Plan 2020 to 2041

    Emerging: examination and post-hearing work. Submitted 23 June 2025; Stage 2 hearings in 2026.

    Post-hearing actions and suggested modifications remain part of an examination. Publication of an action list does not bring the replacement plan into force.

Published milestones and events

Check the official programme before attending a hearing or relying on a deadline. A consultation, hearing or inspector's report is distinct from adoption. This page is a checked snapshot, not a live calendar.

Local design and supporting guidance

Use the 2024 Character, Sustainability and Design Codes for current local extension-design guidance; the council expressly says they supersede its 2017 residential-extension guidelines.

The 2025 climate SPD adds technical guidance. Neither design codes nor an SPD alone establish that an extension is permitted development.

  • Character, Sustainability and Design Codes SPD

    Adopted supplementary guidance. May 2024.

    Adopted .

    Local design guidance with borough-wide principles, site typologies and neighbourhood chapters. It supersedes the former Residential Extensions Guidelines SPD 2017.

Design guidance does not establish that work is permitted development. Check the national rules, planning conditions and any relevant local restrictions.

What to do for your property

  1. Locate the property on the correct adopted map sheet.
  2. Identify the applicable adopted allocation and design policies.
  3. Read the relevant 2024 neighbourhood and typology design-code sections.
  4. Check post-hearing updates after the 18 September deadline.
  5. For a waste-related proposal, check the joint plan and the separate replacement consultation.

Keep the document versions, maps and date of your check with your project notes. A boundary, policy conflict or transition may need assessment by the relevant authority or a suitably qualified planning professional.

Sources, review and changes

These AI-assisted checks cover published document identity, status, dates and links. They do not decide how policy applies to an individual site, and professional planning review has not been completed.

Source-check dates describe when we inspected the source. They do not renew automatically when the website is rebuilt. We link to official documents without claiming a licence over them or republishing them.
