Planning Permission in Lambeth
London Borough in London · Last updated April 2026
Lambeth is one of London's most diverse and densely populated boroughs, stretching from the South Bank and Waterloo in the north to Streatham and Crystal Palace in the south. The borough encompasses distinctive neighbourhoods including Brixton, Clapham, Kennington, Vauxhall, Herne Hill, and Norwood, with housing ranging from Georgian terraces and Victorian villas to inter-war council estates and modern riverside apartments. Planning policy is guided by the Lambeth Local Plan (2021) and the London Plan, supplemented by the comprehensive Lambeth Design Guide SPD (adopted August 2023).
Lambeth has 65 conservation areas and 4 Article 4 Directions that significantly shape what householders can do without planning permission. Three Article 4 Directions target Class MA commercial-to-residential conversions, covering the Central Activities Zone (CAZ), Key Industrial and Business Areas including the West Norwood Creative Business Cluster, and selected town centres including Brixton and Streatham. A fourth direction (2024) restricts HMO conversions in Streatham wards. The Kennington, Oval and Vauxhall (KOV) Neighbourhood Plan was adopted in January 2026 following a successful referendum, adding a further layer of local planning policy. The borough's approval rate of 78.4% is below the national average of 87%.
Major regeneration continues to transform the borough, particularly around Vauxhall, Nine Elms, and Waterloo, with the South Bank remaining one of London's most significant cultural quarters. The borough has no Green Belt, but northern parts fall within the Central Activities Zone where strategic views of St Paul's Cathedral and the Palace of Westminster are protected under the London View Management Framework. Lambeth's Housing Delivery Test score of 74% means the tilted balance presumption in favour of sustainable development applies, which can benefit applicants for housing schemes.

Permitted development in Lambeth
Permitted development rights in Lambeth follow the General Permitted Development Order 2015 (as amended), but are significantly restricted across much of the borough. Properties within any of the 65 conservation areas face tighter controls on cladding, roofline alterations, satellite dishes, boundary treatments, and certain extensions. The Lambeth Design Guide SPD (2023) — a five-part document covering all development types including a dedicated basements section — is a material consideration in all planning decisions. Basement and subterranean development is a notable issue in Lambeth: Part 5 of the Design Guide sets out detailed requirements for structural assessments, construction management plans, and impact on neighbouring properties. For properties outside conservation areas and the CAZ, standard permitted development rights apply for rear extensions (up to 4m detached, 3m others), loft conversions, outbuildings, and solar panels, subject to the usual conditions.
What Lambeth expects from your project
Lambeth's design expectations are set out in the comprehensive Lambeth Design Guide SPD (adopted August 2023), which covers five parts: introducing Lambeth's character, advice for all development, new buildings, building alterations and extensions, and basements. The council operates a Design Review Panel (established 2019) for major schemes and complex proposals. For householder applications, officers assess impact on street scene, neighbour amenity (daylight, sunlight, privacy), and compatibility with the character of the surrounding area. In the CAZ and around the South Bank, strategic views of St Paul's Cathedral and the Palace of Westminster are protected under the London View Management Framework. Brixton is designated a Creative Enterprise Zone by the Mayor of London, and the borough operates four CIL charging zones with residential rates ranging from £200 to £400 per square metre.

Local Plan: Lambeth Local Plan
The Lambeth Local Plan was adopted in September 2021, replacing the Unitary Development Plan (2007) and Core Strategy (2011). The plan covers major regeneration areas at Waterloo, Brixton, Vauxhall and Clapham. The London Plan (2021) also applies.
65 conservation areas
Lambeth has a high number of conservation areas. Check whether your property falls within one before starting any work — conservation area status significantly restricts what you can do without planning permission.
78.4% approval rate
Lambeth's planning approval rate is below the national average of 86.9%. If your project needs planning permission, consider pre-application advice before submitting — it significantly reduces refusal risk.
Conservation areas in Lambeth
65 designated conservation areas
Lambeth has 65 conservation areas — among the highest of any London borough — reflecting centuries of architectural heritage from Georgian townhouses in Kennington to Victorian villa suburbs in Gipsy Hill and Edwardian streets in Streatham. Notable areas include Roupell Street, Albert Square, Abbeville Road, Lansdowne Gardens, Herne Hill, The Chase, Brixton Road, Clapham Old Town, Kennington, and Vauxhall Gardens. The borough has 949 listed buildings, including 6 at Grade I (notably Lambeth Palace, the Royal Festival Hall, and St Mary-at-Lambeth), 56 at Grade II*, and 887 at Grade II. Listed building consent is required for virtually all works to listed buildings, both internal and external. In conservation areas, demolition of unlisted buildings, walls, fences, and trees over 75mm diameter requires consent. The Lambeth Design Guide SPD Part 4 provides detailed guidance on building alterations and extensions within heritage settings.
Article 4 directions in Lambeth

Listed buildings in Lambeth
There are 949 listed buildings in Lambeth. If your property is listed, permitted development rights are significantly restricted. Most external and many internal alterations will require listed building consent, which is separate from planning permission. Always check with Lambeth's conservation team before starting any work on a listed property.
Planning application statistics
Year ending September 2025 | Source: MHCLG planning application statistics
Lambeth received 1,914 planning applications and decided 1,654 in the year ending September 2025. The approval rate of 78.4% is below the national average of 86.9%. Major applications are expected to be decided within 13 weeks, while householder and other non-major applications have an 8-week target. The “in time” figures include decisions made within agreed extensions of time.
Lambeth approved 78.4% of planning applications in the year ending September 2025, below the national average of 87%. Householder decisions were made within target in 96.2% of cases, and major applications achieved a 100% on-time rate. The 98.2% delegation rate means almost all decisions are made by officers under delegated authority. Lambeth's Housing Delivery Test score of 74% is just below the 75% threshold, meaning the tilted balance presumption in favour of sustainable development applies — this can benefit applicants for new housing proposals. Pre-application advice starts at £583 for standard householder proposals (£928 in conservation areas, £1,326 for listed buildings), with a 35-day turnaround, and there is no free duty planner service. The borough's significant development pipeline includes ongoing regeneration at Vauxhall, Nine Elms, and Waterloo, contributing to housing delivery targets.
If your project complies with permitted development rules, you don't need to worry about approval rates — a Lawful Development Certificate is a factual assessment, not a judgment call.
Housing delivery in Lambeth
Housing Delivery Test 2023 measurement | Source: MHCLG
Lambeth delivered 2,624 homes against a requirement of 3,559 over the three-year measurement period, giving a Housing Delivery Test score of 74%. This is well below the 75% threshold, which triggers the most significant consequence: the “presumption in favour of sustainable development” (also called the “tilted balance”). This means planning applications for housing should be approved unless the harm would significantly and demonstrably outweigh the benefits. For homeowners, this is a strong signal — Lambeth is under considerable pressure to approve housing, making it one of the more favourable environments for residential planning applications in England.
Lawful Development Certificates in Lambeth
A Lawful Development Certificate (LDC) is formal confirmation from Lambeth that your project is lawful under permitted development rules. It is not legally required before you build, but it is the only official document that proves your project did not need planning permission. Most solicitors will ask for one when you come to sell, remortgage, or insure your property.
Lambeth decided 575 householder applications in the year ending september 2025. Their 8-week performance of 96.2% is above the national average of 93%, which suggests LDC applications are likely to be processed on time. LDC applications follow the same 8-week statutory determination period as householder planning applications.
How to apply for an LDC in Lambeth
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Lambeth's website. You will need to submit:
- A completed application form (available on the Planning Portal)
- A site location plan at 1:1250 or 1:2500 scale
- Existing and proposed floor plans and elevations
- A written description of the proposed works and how they comply with the GPDO 2015
- The application fee of £258
Lambeth must issue a decision within 8 weeks. If the application is approved, the certificate is a permanent legal record that the development is lawful. If refused, you can appeal to the Planning Inspectorate or amend your project and reapply.
