The short answer
Brent has 22 conservation areas, and its residential ones are covered by Article 4 directions that mostly control the street side of a house rather than the back. A rear loft is therefore often a question of the front slope, windows and chimneys. Where a direction applies, Brent also wants a heritage statement. Our fee is £475 drawings + £150 survey (£625 total), no VAT to add; the council’s fee is separate.

Address check
We place your house on Brent’s conservation area map and read the direction that goes with it, if there is one.
Survey
We measure the roof and floors below, photograph the street elevation and note chimneys and front windows the direction may protect.
Draw to the list
Existing and proposed elevations, floor plans, sections with levels and a roof plan, all at 1:50 or 1:100.
Submit and follow
We send the application with any heritage statement and answer the case officer. Brent makes an application invalid if it disagrees with a justification for leaving something out.
Brent’s conservation area directions look at the front, not the back
Brent’s own Cabinet report describes the directions it replaced in 2020 as covering the street elevations of dwellings: front walls and piers, front gardens, windows, porches, chimneys and satellite dishes, plus outbuildings in rear gardens. It says the new directions will not apply to rear elevations, so properties keep their rights relating to rear extensions.
For example, a Queen’s Park terrace owner planning a rear dormer deals mainly with the chimneys and the front windows the direction protects, while a rooflight on the front slope is another matter and we draw it carefully. The wording differs by area, so we read the one that covers your road.
What Brent’s validation list adds
Brent’s householder list asks for existing and proposed elevations, floor plans, sections with finished floor levels and roof plans, normally at 1:50 or 1:100. A heritage statement is required for householder applications in conservation areas and for works covered by an Article 4 direction. An ecological assessment is asked for where a protected species is reasonably likely to be present, which can include roofs.
If you leave something out you must justify it in writing, and Brent will make the application invalid if it disagrees. Postal applications need two hard copies of every document.
Timing and CIL in Brent
The council gives no decision date on its list, and neither can we. What we can control is a clean first submission. Brent’s checklist applies its CIL form to applications adding 100 square metres or more of new floor space.
Brent’s own CIL, set at £200 a square metre in 2013, is index-linked to £357.14 for permissions granted in 2026, with Mayoral CIL on top. A typical loft is under the 100 square metre mark, so the levy usually does not arise.

Questions about loft conversions in Brent
Does an Article 4 direction stop a rear dormer in Brent?
Brent’s residential directions were designed for the street side of a house, so a rear dormer is judged separately. We read the direction for your area to confirm, because the wording differs.
Do I need a heritage statement for a Brent loft?
Yes where the house is in a conservation area or the works come under an Article 4 direction. We write it with the drawings.
Will Brent ask for a bat survey?
Its list asks for an ecological assessment where a protected species is reasonably likely to be present. An older roof next to trees raises that chance, and we flag it on the survey.
What if I leave something off my application?
Brent asks for a written reason, and makes the application invalid if it disagrees. We prepare the full set to avoid that.
