How much does a rooflight planning application cost?

Why no honest page quotes you a figure

Planning fees in England come from regulations made by the Secretary of State. A council cannot charge more or less than the schedule says, which is why the fee at Oxford City is the same as the fee at Cherwell, West Oxfordshire, Vale of White Horse, South Oxfordshire or any of the authorities across our radius.

The schedule is amended, and in recent years it has been uprated annually rather than left alone for a decade at a time. Any figure written into a web page dates within months. The reliable source is the fee page on the council’s own website, or the fee calculator on the Planning Portal, both of which are updated when the regulations change.

So the useful thing this page can do is tell you which charges exist, which ones apply to a rooflight, and which of them will actually dominate your budget.

Listed building consent is free to apply for

There is no application fee for listed building consent. That surprises people, and it is a deliberate policy: the state requires the consent, so the state does not charge for asking.

It does not make a listed building the cheap option. The work needed to produce a consentable application is greater, because the drawings have to be more detailed and a written heritage statement is expected. The saving on the fee is spent several times over on the documents.

Where a proposal needs both listed building consent and planning permission, which happens when the rooflight is also outside permitted development, the planning fee is payable on the planning side and the consent side remains free.

What you pay for on a rooflight, item by item

Note the two certificate rows. A certificate for proposed development costs less than a certificate for development already carried out, which is one of the quieter arguments for asking the question before the scaffold goes up rather than after.

Drawings are the number people underestimate

A validated application needs a location plan at a recognised scale with the site outlined in red, and existing and proposed drawings of the roof: plan, and elevations of every slope the work is visible from. On a listed building add a section through the opening showing how the unit sits against the rafters and where the covering terminates.

Those are drawn by an architectural technician, an architect or a measured survey firm, and their fee runs to a multiple of the application fee. It is the single largest line for most people, and it is the one nobody budgets for because the question they asked was about the council.

Two things reduce it. First, ask what the council’s validation checklist actually requires, because paying for drawings nobody asked for is common. Second, give whoever draws it a real dimension for the unit rather than a generic rectangle. A manufacturer’s technical sheet gives frame size, kerb or flashing detail and projection, and a drawing produced from those numbers does not have to be redone when the unit is chosen.

Heritage statements, and when they carry a fee

Where the building is listed or the setting is sensitive, a written statement of significance and impact is expected with the application. A capable owner can write a short one for a single rooflight, and our page on writing a heritage statement for a rooflight sets out the structure that works.

Where the case is difficult, a Grade II* building, a prominent slope, an earlier refusal, a heritage consultant is worth engaging, and their fee will typically exceed everything else on the list combined. That is not a reason to avoid it. On a genuinely marginal proposal it is the difference between a consent and a year lost.

Pre-application advice is priced by each council

Unlike the application fee, pre-application charges are set locally, so they differ across the radius and are banded by the type of enquiry. Some authorities also run free duty-planner sessions that answer a simple question at no cost. Whether the paid version earns its money depends entirely on the case, which we cover on pre-application advice and when it pays.

The short version for budgeting: on a rear slope of an ordinary house, it is money you do not need to spend. On a listed building where the officer’s view will decide the design, it is the cheapest information you will buy.

Costs that arrive after the decision

A permission is not always the last invoice. Conditions requiring details to be approved before work begins are common on listed buildings and on conservation area consents, and discharging one is a further application with its own fee under the same national schedule.

Read the conditions the day the decision letter arrives. A condition spotted in week one costs a fee and a few weeks. The same condition spotted the week before installation costs the installation slot as well.

Refusals, resubmissions and appeals

An appeal to the Planning Inspectorate against a householder refusal carries no fee. It costs time instead, several months of it, and any professional help you take to prepare it.

The concession that once allowed one free resubmission of a similar application within twelve months has been narrowed, and it should not be assumed. Ask the council directly whether a second application at your address attracts a fee before you build a strategy around avoiding one.

None of these charges are ours

We install and replace rooflights. Heritage Skylights does not submit applications and does not act as your planning agent, so none of the charges above are ours and we take no percentage of them.

What we do supply, free, is the technical content the application needs: the exact unit, manufacturer and model, the frame dimensions, the published projection above the plane of the slope, the flashing or kerb detail, and how the covering terminates against it. Applications that describe a rooflight in general terms attract a request for further information, and that request costs more in delay than any fee on this page. Our two-figure approach applies as usual: a range by email, then a fixed price after a survey, with the installation carrying a ten-year workmanship guarantee.
