Window & Door Planning Hub
Start with the property, postcode, and work you are considering. This hub combines an official local-constraint search with practical guidance for replacement windows, new openings, doors, rooflights, listed buildings, and Building Regulations in England.
Check the local planning picture before choosing the product.
Search current government planning datasets for the local planning authority and potential conservation, Article 4, listed-building, and landscape constraints.
- Uses the Ministry of Housing, Communities & Local Government Planning Data service.
- Only the postcode is checked; no name, email, or full address is required.
- An initial screen, not a legal determination or certificate of lawfulness.
Review the matches and follow the official links.

Important: planning.data.gov.uk is a developing service and coverage varies by authority. A match should be investigated; no match does not prove that the property is unrestricted. Confirm the position with the local planning authority before ordering or starting work.
The property type changes the answer.
These are screening prompts for England, not a substitute for the local authority's written view.
Ordinary house
Repairs and windows or doors of similar appearance do not usually need a planning application under national guidance.
- Check upper-floor side-window conditions.
- A new bay is treated as an extension.
- Local Article 4 directions can remove rights.
Flat, maisonette, or commercial property
Householder permitted-development rights do not apply in the same way, so external changes need a specific local check.
- Review planning history and original conditions.
- Check lease or freeholder consent separately.
- Confirm signage or shopfront controls where relevant.
Listed or designated property
Significant work to a listed building needs listed-building consent. Conservation and other designated areas can carry additional restrictions.
- Do not order before the consent route is clear.
- Record why repair is not reasonably practicable.
- Match material, profiles, glazing pattern, and opening method carefully.
Four checks before manufacture.
Move from a broad online screen to a documented project decision.
- 01
Confirm property status
House or flat, freehold or leasehold, listed or unlisted, conservation area, Article 4 direction, and any planning conditions.
- 02
Define the visible change
Record each elevation, frame material, colour, sightline, glazing pattern, opening method, cills, bars, and any change to the opening.
- 03
Get the right written confirmation
Use local pre-application advice, a planning application, listed-building consent, or a lawful-development certificate where appropriate.
- 04
Confirm Building Regulations
Agree the competent-person or Building Control route and the documents that will be issued on completion.
Planning approval is not Building Regulations approval.
Replacement external windows and doors are controlled fittings. Since April 2002, replacement glazing has been within Building Regulations in England.
Read the official Building Regulations guideThermal performance
Whole-window and door performance, glass, frames, and installation details must meet the current applicable standards.
Escape and fire safety
Replacement windows should preserve required escape potential; boundary conditions can also affect fire-resistance requirements.
Ventilation
Background and purge ventilation must be considered with the room, existing system, and current Approved Document F guidance.
Safety glazing
Critical locations around floors, doors, and side panels require suitable safety glazing and documented specification.
Accessible thresholds
Main entrance replacement should not make access worse, particularly where a level threshold formed part of the original compliance.
Completion evidence
Keep competent-person certificates or Building Control completion documentation with guarantees and product records.
Give the authority enough detail to answer clearly.
Better evidence reduces ambiguous advice and late redesigns.
- Current photographsEach affected elevation, close-ups, and wider street context.
- Existing and proposed drawingsOpening sizes, frame proportions, sections, and glazing pattern.
- Material and finishFrame material, colour reference, texture, and dual-colour treatment.
- Visible detailsMullions, transoms, glazing bars, horns, cills, vents, and hardware.
- Reason for replacementCondition, repair history, defects, and why retention is not practical.
- Property recordsListing description, conservation appraisal, Article 4 notice, lease, and past permissions.
Continue with official guidance.
Use current national and local sources rather than relying on a generic checklist alone.
Answers before you commit.
Do replacement windows normally need planning permission?
In an ordinary single dwellinghouse, repairs and replacement windows or doors of similar appearance often do not require a planning application. Flats, listed buildings, designated areas, Article 4 directions, new bays, rooflights, and materially different designs need additional checks.
Does a competent-person certificate replace planning permission?
No. A competent-person scheme deals with Building Regulations compliance. Planning permission, listed-building consent, landlord consent, and local restrictions are separate matters.
What does an Article 4 direction mean for windows and doors?
An Article 4 direction can remove specified permitted-development rights in a defined area. Work that would normally avoid a planning application may therefore require one. The exact direction and property coverage must be checked with the local planning authority.
Is a postcode search proof that no restrictions apply?
No. Government planning datasets are still developing and a postcode can cover several properties. A clear result is a useful warning; no result is not a certificate of lawfulness or formal confirmation from the local planning authority.
What should I prepare for a planning conversation?
Prepare photographs of each affected elevation, the property address and status, existing and proposed drawings, material and colour information, frame profiles or sightlines, opening methods, and a short explanation of why replacement is needed.
Bring the planning context into the product conversation.
Share photographs, property status, drawings, and any council guidance. We can then discuss suitable systems without treating the planning position as an afterthought.
