What counts as a material planning objection in London and what does not
Planning law in England distinguishes between material planning considerations (legally relevant to a planning decision) and non-material matters (legally irrelevant, which a planning officer must disregard when making their recommendation). Understanding this distinction is essential to making an effective planning objection in London. Material planning considerations include: loss of daylight or sunlight to habitable rooms (assessed under the BRE daylight and sunlight methodology — a '25° or 45° obstruction angle' test is commonly applied); overshadowing of gardens and amenity space; overlooking and loss of privacy (new windows directly overlooking a habitable room, balcony, or garden); noise and disturbance during construction or from the completed development; traffic generation, parking impact, and highway safety; impact on the character and appearance of the area (particularly significant in conservation areas and listed building settings); loss of trees or green infrastructure; impact on archaeology or heritage assets; biodiversity impact (protected species, SSUI proximity). Non-material matters that planning officers must disregard: the effect of the development on the market value of adjacent properties ('it will reduce my house price' is not a material consideration); personal circumstances of the applicant; boundary disputes or private disputes between neighbours; competition (a new business competing with an existing one); disruption during lawful construction works (some disruption is inherent in any building project — unless the proposed works pose exceptional construction-phase risks, this is not a planning matter); and aesthetics alone without reference to policy (purely personal dislike of the design is not material unless it demonstrably conflicts with adopted design policy). Effective objections cite the specific policies that the proposal conflicts with (the borough's Local Plan, the London Plan, and national policy in the National Planning Policy Framework) rather than making general or emotional representations.
How to submit a planning objection and what happens next in London
Planning applications in London are publicly available on each borough's planning portal (accessible from the borough council website under 'Planning Applications'). The Planning Portal also provides a national search facility at planningportal.co.uk. When a valid application is submitted, the LPA sends consultation letters to all adjoining and nearby occupiers (defined differently by different boroughs — typically the immediately adjacent properties and sometimes those in a wider radius for larger applications) and the application is posted on the council's planning portal and sometimes a site notice is attached to the property. The consultation period for most householder applications is 21 days from the date of the consultation letter or site notice, whichever is later. You can submit your representation: online via the borough's planning portal (most boroughs now require or strongly prefer online submissions); by email to the planning case officer named in the consultation letter; or in writing to the planning department. There is no required format — a clear, structured representation citing specific material considerations and the relevant policies is most effective. Anonymous representations are not usually accepted. What happens after representations are submitted: the planning case officer prepares a report to the delegated officer (if the application can be decided under delegated powers) or to the planning committee (if called in by elected members or exceeds the threshold for committee determination). In London, most householder applications are decided under delegated powers (by a planning officer without a committee hearing). A planning committee hearing requires a minimum number of councillors (usually 3–5 on the planning committee) to request it, typically on the grounds that the application is contentious or the officer's recommendation is controversial. Members of the public can speak at a planning committee hearing — typically 3 minutes per speaker (objectors and supporters are allocated equal total time). If the application is approved despite representations, the decision cannot be directly challenged by a neighbour — judicial review is available only on legal grounds (not planning merits). If the application is refused, the applicant can appeal to the Planning Inspectorate and neighbours can submit representations to the appeal.
