HMOs of six or more occupants require Sui Generis planning permission. Key grounds include residential character, parking pressure, noise, and HMO concentration policy thresholds that apply in many local plans.
Read full guide →Loss of light to habitable rooms is a material planning consideration. BRE daylight guidance provides the technical framework. Overbearing impact — where a structure creates an oppressive sense of enclosure — is also a recognised ground.
Read full guide →New windows, balconies, or raised terraces that create direct overlooking into principal rooms or private garden areas are a recognised planning concern. Distance standards and outlook policies provide the framework.
Read full guide →Green Belt policy under the NPPF 2024 (where applicable) establishes a strong presumption against most forms of new development. Inappropriate development must demonstrate very special circumstances. We engage with this framework for Green Belt objections.
Read full guide →Applications that cram too many units onto a site, or that extend properties beyond what is appropriate for the plot, can be challenged on overdevelopment grounds — engaging density, space standards, and amenity policies.
Read full guide →Developments that generate additional traffic movements or exacerbate existing parking pressures can be challenged on highway safety and amenity grounds. Councils' adopted parking standards provide the policy basis.
Read full guide →The NPPF 2024 (where applicable) places significant weight on design quality. Proposals that are out of scale, use inappropriate materials, or fail to respect the character of the surrounding area can be challenged on design and character grounds.
Read full guide →Applications affecting listed buildings, conservation areas, scheduled monuments, or their settings engage the heritage harm tests in NPPF 2024 (where applicable) Chapter 16. These protections are among the strongest in the planning system.
Read full guide →Extensions to neighbouring properties can be challenged where they cause loss of light, overlooking, overbearing impact, or harm to the streetscene. Permitted development rights and the 45-degree test are relevant considerations.
Read full guide →Noise and disturbance from a proposed development can be a valid planning ground where it would harm the amenity of neighbouring residents. This guide explains when noise is material and how to frame it.
Read full guide →Overshadowing occurs when a proposed building blocks sunlight to neighbouring properties or gardens. BRE guidance on sunlight hours provides the technical framework for these objections.
Read full guide →New dwelling proposals — including infill, backland, and Permission in Principle applications — raise specific policy issues around character, density, amenity, and access.

Read more →How councillors influence planning decisions, when to involve them, and what they can and cannot do to support your objection.
Read more →How appeal decisions and case law can strengthen your planning objection by demonstrating how similar proposals have been refused elsewhere.

Read more →When a proposed development threatens the viability or operation of local businesses, this can be a material planning consideration in certain circumstances.
Read more →AI-generated objection letters are flooding council portals with fabricated case law and generic arguments. We explain the risks — including costs awards — and why professional research cannot be replaced by a language model.
Read full guide →There is no magic number. One well-researched objection can stop a development; a thousand weak letters can fail. This guide explains what actually influences planning decisions and the optimal objection strategy.
