264 articlesLand contamination phase 1 or phase 2: which you need
A phase 1 desk study decides whether intrusive investigation is needed at all. The trigger is a plausible pollutant linkage, not site history on its own.
Lawful development certificate or planning permission first
A lawful development certificate is decided on law and fact, with no room for neighbour objections. When to use one, and when a planning application is safer.
Prior approval or planning permission: the real difference
Prior approval and planning permission are different animals. What the council may examine, the 56 day deemed consent, the conditions each route carries and where appeals go.
Demolition in a conservation area: what consent applies
Relevant demolition replaced conservation area consent in England in 2013. Which structures are caught, which fall under the exclusions, and what the council expects to see.
Viability at plan making or at application stage
Compliant schemes are assumed viable, so an application stage assessment has to earn its place. The circumstances that justify one and the evidence that survives review.
Outline or full permission for a small residential site
Outline suits a landowner selling with consent. A self-builder who intends to build usually gains more from a single full application. The fees, timing and risk compared.
BS 4142 or ProPG: choosing the right noise method
BS 4142 and ProPG answer opposite questions. A practical guide to which method applies, how background sound differs between them, and the errors that trigger a resubmission.
Energy Statement or Whole Life Carbon Assessment
The two documents answer different policy questions, and design moves that improve operational carbon can worsen embodied carbon. Which applies, when, and how to report both.
Class E or sui generis for a food and drink business
A restaurant is Class E(b) and a hot food takeaway is sui generis, so the same premises can need no application or a full change of use. The primary use test decides which.
Rights of light or planning daylight: which risk is which
A private right to light and the planning daylight assessment use different measurements, different decision makers and different remedies. Permission is no defence to an injunction.
Biodiversity net gain or licence compensation for habitat
Both regimes end with an ecologist creating habitat, but they are owed to different bodies and tested differently. Satisfying one does not satisfy the other.
Section 73 or section 96A to change a permission
Section 96A amends the permission you hold. Section 73 gives you a second one. The difference decides your fee, your consultation, your determination period and whether the section 106 still binds.
Ownership certificates A, B, C and D compared
Certificates A to D are statutory declarations under section 65 of the 1990 Act. Here is what each one says, the notices that follow and the consequences of getting it wrong.
Advertisement consent or listed building consent for signage
Advertisement consent judges the display on amenity and public safety. Listed building consent judges the works on their effect on special interest. How the two differ and why the listed building risk never expires.
Self-build against residential extension CIL exemption
The whole-dwelling self-build exemption and the annex and extension exemptions use different forms and carry different clawback rules. Here is the sequence that keeps the relief valid.
Biodiversity net gain against nutrient neutrality
Biodiversity net gain is measured in habitat units over 30 years. Nutrient neutrality is measured in kilograms of nitrogen and phosphorus, in perpetuity, and it can stop a permission being granted at all.
Habitats regulations assessment against EIA: what differs
EIA is a procedural duty to inform a decision. Habitats regulations assessment is a substantive prohibition unless integrity can be secured. The difference decides how mitigation is treated and who signs the conclusion.
Schedule 1 against Schedule 2 EIA development
Schedule 1 makes assessment mandatory. Schedule 2 thresholds only decide whether the screening duty arises, and in a sensitive area those thresholds fall away entirely.
EIA screening opinion against a scoping opinion
Screening asks whether your scheme is EIA development. Scoping asks what the environmental statement must address. Different regulations, different deadlines, different submissions.
Tree preservation order against conservation area notice
Under a Tree Preservation Order the council has to say yes. For a tree in a conservation area, six weeks of silence is enough. The two regimes look similar and work very differently.
Class Q against Class R for agricultural buildings
Class Q and Class R sit side by side in Part 3 of the GPDO 2015 and do opposite jobs. The decisive difference is that Class Q permits conversion works and Class R permits none at all.
Committee decision against a delegated decision
The scheme of delegation decides whether a planning officer or the planning committee determines an application. The legal weight is the same, but the process, the timing and your chance to speak are not.
Non-determination appeal against an extension of time
Appealing non-determination takes the decision away from the council entirely, on the scheme as submitted. Agreeing an extension usually trades the fee refund for a negotiation you can still win.
Householder appeal against a full planning appeal
A refused extension goes to the householder appeals service: twelve weeks to lodge, written representations only, and no opportunity to add evidence later. Everything else uses the standard route.
