Planning consultant in the City of London

A planning consultant in the City of London mostly advises flat owners, not house owners: only 2 per cent of households here live in a house. The Square Mile's 637 listed entries and 28 conservation areas decide most cases, so we start with a free constraints check and then give a fixed quote.

    How we work on planning consultant

    Seven steps from first call to approval.

    The same model cut through the middle: every floor, the stair, the chimney breasts, the new mansard, rear extension and basement in section
    Section through the model: every floor on one datum.
    1. Enquiry and constraints check

      We check the property against conservation areas, listed status, Article 4 directions, tree preservation orders, flood zone and planning history. We choose the right route and send a fixed quote.

    2. Measured survey

      We survey the house on one datum: rooms, levels, boundaries, drains, trees and the neighbours' windows that the 45° and 25° tests depend on.

    3. Design options

      We model the house in Revit and show you options in 3D and plan, with the planning strategy and the precedents in your street.

    4. Design frozen

      You choose an option in writing. Nothing changes after this without your say.

    5. Independent check

      A second chartered technologist checks every sheet against the council's validation checklist and the policy. A senior review signs it off before anything is submitted.

    6. Submission

      We prepare the forms, certificates, fee and documents and submit through the Planning Portal.

    7. Officer liaison

      We answer the planning officer and make any amendments within five working days, at no charge until approval.

    Free redraws until approval. Every drawing set is checked independently, and the checker is never the person who drew it.

    The City's own rules for residential alterations

    The council's development plan is the City of London Local Plan 2015, which dates from well before the current national framework. Officers still apply it, alongside newer national policy, so a statement here has to explain why a scheme meets an older text as well as the current national framework. That is a real piece of work and the reason a consultant is worth a call before any drawing starts.

    For residential projects the document that matters most is the Barbican Estate Listed Building Management Guidelines: Volume I Introduction and Volume II Residential (SPD). Much of the City's housing is in the Barbican, where the listing covers the estate's concrete, glazing and landscape, not only individual flats. An internal change that looks minor to the owner can still need listed building consent, so we check the listing description before suggesting a route.

    Developer contributions also look different here. The council's charging schedule is the City of London Community Infrastructure Levy Charging Schedule, which sets one residential rate for the Riverside and a lower one for the rest of the City, and the Mayor's rate adds 80 pounds per square metre before indexation. A conversion that adds floor area should be tested against these numbers early.

    Why householder statistics barely exist in the Square Mile

    In the latest twelve months we hold, the City council decided 1 householder application. That is not a typo. With so few houses, the usual comfort of a borough-wide grant rate disappears, and the single decision tells you nothing about how a case officer would treat yours.

    Minor applications give a better picture: 173 decisions, 97.1 per cent granted and 93.1 per cent decided in time. Across every type the council handled 477 decisions, a small caseload next to the larger boroughs. A small caseload means each file is read closely, so a well-documented submission is easy to process and a thin one stands out. We therefore spend our time on the heritage statement and the drawings, the two documents an officer here reads first, and we keep the planning statement short and tied to the policies that apply.

    Heritage, archaeology and the weight of the past

    53 scheduled monuments intersect the council's boundary, and 86 of the listed entries are Grade I. Below-ground work therefore attracts archaeological questions that a suburban borough rarely asks. A new lift pit or a basement room can need an archaeological desk-based assessment as part of the application.

    There are also 5 entries on the Heritage at Risk Register within the boundary, and only 1 Article 4 direction. Householder permitted development rights do not cover flats at all, so for most City homes the listing matters far more than any direction.

    If you are unsure what protects your building, our architectural drawings page for the City of London sets out the area's constraints in one place.

    What we do for a City flat or small commercial-to-residential job

    Typical briefs are a change to windows in a listed block, an internal reconfiguration, a rear terrace or a conversion of a small office floor to a home. For each we agree the route first. Sometimes that is a Lawful Development Certificate in the City of London to confirm that works are lawful, and sometimes it is a full application with a heritage statement. We also list the neighbours who are likely to comment, because in a block the people on the other side of a party wall are usually the first to write to the council.

    We then prepare a short planning statement, assemble the validation documents and draw the plans and elevations. An independent chartered technologist checks the package, which is never the person who drew it. Officer amendments are turned round within five working days, and redrawing is free until approval.

    Where a project affects neighbours' light, which is common in dense blocks, we advise on a daylight and sunlight report in the City of London. Below-ground works may need a basement impact assessment in the City of London.

    Pre-application, fees and timing

    A non-major application has a statutory period of 8 weeks, and a major one 13 weeks. The householder fee set nationally is £548. Neither number is a promise about your case, and in a listed setting a pre-application conversation often saves more time than it costs.

    Send us the address, the floor and a sentence on what you want to change. We check the listing, any lease restrictions you tell us about and the council's local validation list, then tell you plainly whether you need a consultant, a specialist or only drawings. The service overview is on the planning consultant page. If a lease or a freeholder's consent is also needed, we note that in the same reply so you can start that conversation in parallel.

    Questions

    Do I need listed building consent for a Barbican flat?

    Often yes for external changes and for some internal ones, because the listing covers the estate's design. We read the listing description and the council's guidelines before advising.

    Can I use permitted development for a flat in the City?

    Householder permitted development rights do not apply to flats, so most flat projects need an application or a certificate of lawfulness. We confirm the route in the free check.

    How long does the City council take to decide?

    8 weeks is the statutory period for a non-major case. The council decided 93.1 per cent of minor applications in time, and we cannot promise a date.

    How is your fee set?

    We give a fixed quote after the free constraints check. The council's own fee is separate and paid to the council.
