Conservation areas
in London with a map
Guide & Explained
London has well over a thousand conservation areas, and a large share of the properties sit inside one — which means a huge number of homeowners are subject to these rules. Here's what conservation area status genuinely changes, and how to check your own.

What a conservation area actually is
A conservation area is a zone designated by the local council as having special architectural or historic character worth preserving. It doesn't protect individual buildings the way listing does — instead, it restricts changes that would affect the character of the area as a whole, particularly anything visible from the street.
Being in a conservation area is a different thing from your building being listed, and the two often overlap but don't have to. A property can be in a conservation area without being individually listed, and vice versa, though it's less common for a listed building to sit outside one.

What changes, in practice
Permitted development rights are reduced. Extensions, alterations, and changes that a house outside a conservation area could make automatically often need a full planning application inside one.
Some areas go further with an Article 4 direction. This is a specific legal order a council can apply on top of standard conservation area status, removing permitted development rights entirely for certain categories of work — window and door replacements, render and cladding changes, and boundary treatments are common targets. Where an Article 4 direction applies, even a straightforward like-for-like change can need a full planning application. Article 4 directions are applied street by street or even property type by property type within a single conservation area, so it's genuinely possible for two neighbouring streets in the same conservation area to be treated differently.
Demolition is more controlled, including for garden walls and outbuildings that wouldn't normally need permission.
Trees can be protected even without an individual Tree Preservation Order (TPO), simply by virtue of being in a conservation area — cutting down or significantly pruning a tree with a trunk over roughly 75mm in diameter can require six weeks' written notice to the council before any work starts.
External appearance gets more scrutiny — window replacements, render and paintwork changes, roofing materials, and even satellite dishes and solar panels can all be subject to tighter rules than the same change would face elsewhere.
Internal work is generally unaffected — a conservation area on its own doesn't restrict what you do inside the building, unless the property is also listed.
Conservation area appraisals: the document worth reading
Many councils publish a conservation area appraisal for each designated area — a document explaining exactly what makes that specific area special, which features the council considers worth protecting, and general guidance on how new work should be approached. If one exists for your area, it's genuinely useful reading before finalising any exterior design, since it often tells you in plain language what a planning officer will actually be looking for.
Areas of London with significant conservation area coverage
Conservation area density varies enormously by borough, and within boroughs, street by street. Some of the areas with particularly extensive coverage include large parts of Hampstead and the wider borough of Camden, most of the Royal Borough of Kensington and Chelsea — South Kensington included — significant sections of Richmond and Wandsworth, and large portions of the City of Westminster. Closer to the river, parts of Hammersmith and Fulham carry the same designation, and pockets of Hackney, particularly around its Georgian and Victorian squares, do too, despite the borough's reputation for a more mixed, modern streetscape overall. This isn't an exhaustive list — many boroughs have dozens of individually designated conservation areas, sometimes covering a handful of streets each rather than a whole neighbourhood.
The practical takeaway: don't assume based on the general reputation of an area. Two streets in the same postcode can have entirely different status.
Fulham SW6
Hammersmith W6
Fulham shares its conservation area coverage with the rest of the London Borough of Hammersmith and Fulham, with several distinct areas protecting the Victorian terraces that make up most of its housing. Coverage follows the original street-by-street development rather than one continuous zone, so neighbouring roads can have different status — and Fulham listed buildings tend to cluster along the same older streets. If you're planning a kitchen renovation in Fulham that touches the exterior, or a full house refurbishment, check your specific Fulham conservation area status before finalising a design — see our Fulham renovation guide for more.
Hampstead sits within the London Borough of Camden, one of the most extensively covered boroughs in the capital — large parts of the Hampstead conservation area, along with neighbouring areas like Hampstead Garden Suburb, protect everything from Georgian townhouses to Arts and Crafts detailing. Hampstead listed buildings and the hilly, narrow lanes that complicate renovation access are often on the same streets under the tightest scrutiny for exterior changes. If you're planning an apartment renovation in Hampstead or a project on a full house, status affects both differently — our Hampstead renovation guide covers what to expect.
Much of the Chelsea conservation area protects the Victorian and Georgian terraces that define streets like Cheyne Walk and the King's Road, and Chelsea listed buildings are common along both. A meaningful share of Chelsea's housing also sits under shared freeholds, so an exterior change can require both conservation area rules and sign-off from a freeholder or fellow leaseholders. If you're planning a kitchen or home renovation in Chelsea involving structural or exterior work, check both early — full detail is in our Chelsea renovation guide.
Kensington has some of the highest conservation area coverage in London — in parts of Kensington, it's more unusual to be outside the Kensington conservation area than inside it, and Kensington listed buildings are correspondingly common. The borough's stucco-fronted garden squares are a big part of why: those white and cream facades are often protected as much by convention and freeholder agreement as by formal planning rules. Anyone planning a property or bathroom renovation in Kensington, particularly on a listed building, should treat this as a first step — our Kensington renovation guide goes into what's realistic.
Hammersmith's conservation area coverage is more varied than neighbouring boroughs, reflecting the mix of building types — Victorian terraces and riverside conservation areas near the Thames sit alongside newer development outside any designation. Hammersmith listed buildings and Hammersmith conservation area status both depend heavily on which street a property is on. If you're planning a property renovation in Hammersmith, particularly riverside, check the map above before assuming either way — or see our Hammersmith renovation guide for more.

Planning permission cost and timeline
Cost. A standard householder planning application costs a few hundred pounds as a council fee — this varies slightly by nation, and larger or non-householder applications are charged more. That fee is separate from any drawings, structural calculations, or heritage statements you pay a professional to prepare, which is usually the bigger cost of the two. If an application is refused, you can normally resubmit a revised version once within 12 months without paying the fee again, but a second attempt from scratch, or an appeal, does mean further cost and further delay. Pre-application advice, where a council gives informal feedback on a proposal before you submit formally, typically costs somewhere between £50 and a few hundred pounds depending on the council and the scale of the project — often worth it on anything borderline, since it's far cheaper than a refused application.
Timeline. A straightforward householder application is typically decided within eight weeks of being validated by the council. More complex applications, or ones needing input from additional consultees, can take considerably longer. Before that clock even starts, most applications need a public notice displayed near the property for a set consultation period, giving neighbours the chance to comment or object, which is built into the process rather than something that delays it separately. If you're planning renovation work around a fixed date — a house sale, a tenancy start, a family event — it's worth working backwards from that date and building in the full eight weeks as a minimum, plus contingency time if your proposal is anything other than routine.
FAQ
Common questions
about conservation areas.
Does living in a conservation area affect my council tax or property value?
Not directly through any special charge, though well-maintained conservation areas can support property values by preserving the character that made the area desirable in the first place.
Can I still extend my house in a conservation area?
Often yes, but more likely to need a full planning application rather than relying on permitted development rights, and the design is more likely to be scrutinised for how it fits with neighbouring buildings.
Do conservation area rules apply to flats as well as houses?
Yes, though flats already have more limited permitted development rights regardless of conservation status, so the practical difference is sometimes smaller than for a standalone house.
What if my street is on the edge of a conservation area boundary?
Boundaries are specific and legally defined — a property on one side of a line can be inside the designation while a near-identical one across the road isn't. Always check the exact address rather than assuming based on the surrounding area.
How do I find out if an Article 4 direction applies to my street?
Your council's planning portal will usually list current Article 4 directions by area, or you can call the planning department's duty officer directly.
Is it harder to sell a property in a conservation area?
Not generally — many buyers see it as a mark of a well-preserved, desirable area, though it's worth disclosing any unresolved planning queries during a sale, as solicitors typically check for this.
