How likely is a Greenwich application to be refused?

More likely than in most boroughs. Greenwich approved 70.7% of the householder applications it decided, against 83.0% across London, refusing 674 of 2,301. Its 14 conservation areas cover 884 hectares. On appeal the Inspectorate allowed 39.9% of 571 householder cases.

Where do the conservation area boundaries actually run in Greenwich?

This map shows the designated boundaries as the national register holds them, sitting inside the borough outline. There is a postcode box beneath it; it resolves in your browser, so no address you type is sent anywhere. Read the result as an indication rather than a ruling. The polygons have been generalised for drawing, and a plot that appears to graze the edge of an area is precisely the case the register cannot decide — the council’s own boundary mapping has to.

Two features of the Greenwich records are worth knowing before you lean on them. The designated land covers 884 hectares, but several of the borough’s entries have been uploaded without a name, so they appear on the map as reference codes — including the largest of them, at 376.9 hectares. None of the Greenwich entries carries a link to a council appraisal document either, so the written guidance that normally sits behind a boundary has to be requested from the Royal Borough directly. The Article 4 layer is a separate gap and the more important one: Greenwich has not published any of its directions to the national register, so the layer draws empty. That is silence in the dataset, not an absence of controls, and it is not a reason to assume permitted development is available on a given house.

Answers for Greenwich

How many conservation areas does Greenwich have?

Greenwich has 20 designated conservation areas, including Greenwich Town Centre (World Heritage Site), Blackheath, Charlton, Eltham Park.

What changes need planning in a Greenwich conservation area?

Any external alteration visible from a public space typically requires full planning permission inside a conservation area: roof additions, dormers, replacement windows, rendering, hardstanding, and demolition. Internal works generally do not, unless the property is also listed.

Do I need a Heritage Statement in Greenwich?

Yes — every application inside a conservation area requires a Heritage Statement. It must address the conservation area character appraisal, identify heritage assets, and explain how the design preserves or enhances character. We prepare this as part of every conservation-area application.

Can I have a roof extension or mansard in a Greenwich conservation area?

Rear mansards and dormers are routinely approved in many London conservation areas where the design matches the terrace's existing roofscape — particularly in Hackney, Islington, Tower Hamlets, Lambeth and Southwark. Front-facing dormers are almost universally refused.

How long does conservation area approval take in Greenwich?

Greenwich Council statutory determination is 8 weeks for householder applications. Conservation officer consultation adds 2–3 weeks in practice. Expect 11–14 weeks from validation to decision.

Which Greenwich postcodes does this conservation area application service cover?

Every Greenwich postcode district we draw in, the stock that dominates it and the authority that validates a conservation area application there. Greenwich fees below are the statutory England rates for 2026, not conservation area application estimates.

PostcodeAreaDominant stockWhat it means for a conservation area application
SE2Abbey WoodGeorgian in Greenwich town centre; Victorian terraces in East GreenwichSE2 straddles a boundary: Abbey Wood addresses fall to Greenwich Council or Bexley Council, so confirm which authority validates the conservation area application before submitting SE2 drawings.
SE3Blackheath / KidbrookeGeorgian villas, Victorian terracesSE3 straddles a boundary: Blackheath / Kidbrooke addresses fall to Greenwich Council or Lewisham Council, so confirm which authority validates the conservation area application before submitting SE3 drawings.
SE7CharltonVictorian villas, 1930s semi-detachedCharlton sits wholly inside SE7, so Greenwich Council validates every conservation area application submitted from an SE7 address.
SE9Eltham / Mottingham1930s semi-detached, post-war flatsEltham / Mottingham is split at SE9. Either Greenwich Council or Bromley Council can determine a conservation area application here, so the SE9 address is checked against both policies maps first.
SE10GreenwichGeorgian terraces, listed buildingsA conservation area application at an SE10 address in Greenwich is determined by Greenwich Council under its own Local Plan policies for Greenwich.
SE18Woolwich / PlumsteadGeorgian fragments, post-war estates, new-buildA conservation area application at an SE18 address in Woolwich / Plumstead is determined by Greenwich Council under its own Local Plan policies for Woolwich / Plumstead.
SE28ThamesmeadPost-war estates, new-buildSE28 covers Thamesmead only; Greenwich Council handles the conservation area application.

Which Greenwich neighbourhoods suit a conservation area application best?

Roof pitch, wall build-up and plot depth change every few Greenwich streets, and each one changes what a conservation area application can achieve at that address.

What local planning policy applies to a conservation area application in Greenwich?

How designation changes a Greenwich conservation area application: Greenwich Council’s own list names 20 conservation areas, including Charlton, Eltham Park, Greenwich Town Centre (World Heritage Site). Inside any of them a Greenwich conservation area application cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Charlton sets the tone for Greenwich casework.

Article 4 and your Greenwich conservation area application: Greenwich Council has made no borough-wide direction, so permitted development for a conservation area application in Greenwich generally survives outside Greenwich conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a SE2 owner records that a conservation area application was lawful.

Greenwich housing stock: Georgian in Greenwich town centre; Victorian terraces in East Greenwich, Charlton; inter-war semi-detached in Eltham; new-build along the riverside. World Heritage Site status in Greenwich town centre adds heritage weight; outer borough areas (Eltham, Thamesmead) generally permissive. Read that before choosing a conservation area application route in Greenwich — construction, not postcode, sets what is achievable.

Who decides a conservation area application on the edge of Greenwich?

Sources for this Greenwich conservation area application page: borough policies maps and conservation-area registers (2025–26), Royal Mail postcode district boundaries, the Town and Country Planning (Fees for Applications) (England) Regulations, the Town and Country Planning (General Permitted Development) (England) Order 2015 as amended, and the Party Wall etc. Act 1996.
