Planning permission architect near me across London

What does a planning agent actually do for you?

‘Agent’ is the formal role recorded on the application. Once appointed, the council correspond with us rather than you: the validation email, the case-officer queries, the consultee comments and the decision notice all arrive at our desk. That matters more than it sounds, because most applications that fail in London do not fail on design — they fail on a validation requirement missed at submission or an officer query left unanswered inside a deadline.

The work divides into four parts. The survey establishes what is actually there, to the millimetre, because a council will refuse a drawing whose existing elevation does not match its own aerial and street imagery. The design work sizes the proposal against the policies that will be applied to it. The submission assembles the set against your borough’s published local validation list. And the case management runs the eight weeks after that.

We are chartered architectural technologists, not registered architects. For a householder or small residential application that is the more relevant discipline and roughly 30% cheaper: the deliverable is a technically accurate, policy-compliant drawing set, and it is priced as a fixed fee rather than a percentage of a build cost nobody has tendered yet.

Why do so many London applications get invalidated?

Invalidation is not refusal. It means the council will not start the eight-week clock because something required is missing, and it is the single most common reason a London homeowner’s application takes four months instead of two. Every borough publishes a local validation list on top of the national requirements, and they differ.

• Site location plan at 1:1250 with the application site edged red and any other land in the applicant’s ownership edged blue, showing at least two named roads and a north point.
• Block plan at 1:500 showing the property boundaries and the position of the proposal within them.
• Existing and proposed floor plans and elevations, conventionally at 1:100 or 1:50, each with a scale bar so the drawing remains measurable after printing or PDF compression.
• Section drawings where the proposal changes floor or roof levels — a loft, a basement, or an extension with a stepped floor level.
• Design and Access Statement for applications in a conservation area or affecting a listed building, and for most schemes beyond householder scale.
• Heritage Statement where the property is listed, in a conservation area, or affects the setting of either.
• CIL Additional Information form — required in every London borough that charges the Community Infrastructure Levy, and a routine cause of invalidation because applicants do not realise a nil-liability scheme still has to file it.

Beyond the checklist, the recurring technical failures are drawings submitted without a scale bar, elevations that omit the neighbouring properties either side, and site plans copied from a mapping website without a licence. Ordnance Survey-derived plans have to come from a licensed supplier; a screenshot is grounds for invalidation on its own.

Which application route applies to your project?

A householder application at £258 covers extensions, loft conversions, dormers, outbuildings and alterations to a single dwellinghouse. A full application at £578 is needed for a new dwelling, a change of use, or a conversion of one dwelling into several — and note that any work to a flat is a full application, because flats are not dwellinghouses for these purposes and have no permitted development rights.

Prior approval sits between the two. The larger home extension route allows a single-storey rear extension of up to 6 metres on a terraced or semi-detached house and 8 metres on a detached house, subject to a neighbour consultation scheme that runs for 21 days. It is decided in six weeks at £120 and is a genuine shortcut where it applies — but it is unavailable on flats, in conservation areas for some elements, and wherever an Article 4 direction has removed the right.

Pre-application advice is the fourth option and is chargeable in every London borough, typically £150 to £600 for a householder scheme. It is worth buying when the scheme is genuinely marginal — a contentious roof form, a basement, or a property whose neighbours have already objected to something similar. It is not worth buying for a standard rear extension, where the money is better spent getting the drawings right first time.

What will the case officer actually assess?

Householder applications in London are decided against the borough’s Local Plan, its adopted householder design guidance, and the London Plan where relevant. Reduced to what changes an outcome, there are five tests.

• Subordination — the addition should read as secondary to the original house in height, depth and roof form. This is why a rear extension with a ridge matching the main roof reads badly and a lower flat or mono-pitched roof reads well.
• Daylight and outlook to neighbours — assessed in many boroughs by the 45-degree rule, taken in plan and section from the midpoint of the nearest neighbouring habitable-room window. Breach it and you invite a refusal on residential amenity.
• Overlooking — new side-facing windows to habitable rooms, roof terraces and raised platforms are the usual triggers. Obscure glazing and restricted opening are the standard mitigation and are best shown on the drawing rather than left to a condition.
• Character of the streetscene — strongest at the front elevation and in conservation areas, where matching materials, window proportions and the rhythm of the terrace carry real weight.
• Amenity space and trees — boroughs resist extensions that leave inadequate private garden, and a Tree Preservation Order or a conservation-area tree within influencing distance brings a separate arboricultural requirement.

Neighbour objections are consulted on but do not decide the outcome. An objection carries weight only where it engages a policy — loss of light, overlooking, noise, parking. Objections about property value, building noise during works, or a private boundary dispute are not material planning considerations and the officer will disregard them.

How long does planning permission take in London?

Eight weeks from validation for a householder application, thirteen weeks for a major application. Validation is not submission — the clock starts when the council confirm the application is valid, which in a busy borough can be one to three weeks after you press submit if anything needs chasing. Getting the set right first time is therefore worth more than any amount of speed in drafting.

• Weeks 1–2 — registration, validation, and publication on the borough’s planning register.
• Weeks 2–5 — the 21-day neighbour consultation and any site notice period, plus internal consultee responses from highways, conservation or trees.
• Weeks 5–7 — the officer’s site visit and assessment. Most negotiation happens here; an officer minded to refuse will often accept an amended drawing instead if one is offered quickly.
• Week 8 — decision, either under delegated powers or, where objections cross the borough’s threshold, at planning committee, which adds three to six weeks.

If the decision is a refusal you have six months to appeal to the Planning Inspectorate for a householder scheme, and the appeal itself is free. In practice an amended resubmission is usually faster and more likely to succeed: you get one free-go resubmission on the same site within twelve months of the original decision, with no statutory fee.

What does a planning agent cost in London?

The fee above covers the measured survey, the full drawing set, the Planning Portal submission and all case management through to the decision notice. Statutory application fees are separate and payable to the council: £258 for a householder application, £578 for a full application, £129 for a Lawful Development Certificate, and no fee at all for listed building consent.

A registered architect in London working on percentage terms would typically charge £3,000 to £8,000 for the equivalent planning-stage package on a domestic project. The gap is not a quality gap; it is a scope and pricing-model gap. We publish the fee, fix it at instruction, and do not bill for the revisions the council ask for.
