The short answer
A loft in Wandsworth is mostly a question of which of the borough’s protected estates you live on. Where rights remain, we draw a Lawful Development Certificate; where they do not, a householder application. Our fee is £475 drawings + £150 survey (£625 total), no VAT to add, and Wandsworth’s application fee is separate.

Estate check
Dover House, Latchmere, Heaver, Shaftesbury Park and Totterdown Fields all carry controls on street-visible work. We start there.
Survey
We measure the roof, the party walls the new beams will need to rest on, and the stairwell below.
Draw
The set carries a scale bar on every sheet, because a drawing without one invalidates a Wandsworth application.
Submit and follow
We submit and watch the file. Wandsworth gives you two months to supply anything missing, and we answer inside that window.
The estates that decide the answer
Wandsworth has 46 conservation areas and a list of estates controlled by Article 4 directions down to the front door. The Shaftesbury Park, Heaver and Totterdown Fields estates have controls over windows, doors, roofs, porches, boundaries and painting. Latchmere Estate carries the same set and extensions on top. Dover House Estate and Roehampton Village are in the same family.
For example, a Victorian cottage in Shaftesbury Park near Clapham Junction looks like a textbook rear dormer under Class B, but the estate’s direction means the roof is no longer a permitted development matter. We read the direction for your road, because the answer changes the application, the drawings and the timetable.
What Wandsworth wants with a loft application
Drawings without a scale bar invalidate an application, and the council allows two months to supply missing information before the application is withdrawn. Anything touching a heritage asset needs a Statement of Heritage Significance and Impact written by a specialist historic environment consultant, and a tree survey by a qualified arboriculturist is asked for where trees stand on or next to the site, neighbours’ gardens and street trees included.
For roof extensions the borough’s Housing SPD of November 2016 is the guidance a case officer works from. It also covers rear extensions and basements, so a combined loft and rear extension is read against one document.
Timing and CIL in Wandsworth
Wandsworth’s target is 8 weeks for householder applications, though the council says it is currently dealing with a high volume after moving to a new planning system. Treat 8 weeks as the aim and not a promise.
The borough’s CIL is £250 a square metre outside the Nine Elms areas before indexation, rising each year with the tender price index. It is charged on new-build floor area of 100 square metres or more, or on a new dwelling, so an ordinary loft is outside it. Mayoral CIL applies at band 1, the highest band.

Questions about loft conversions in Wandsworth
Which Wandsworth estates have Article 4 directions?
The council lists Dover House, Latchmere, Heaver, Shaftesbury Park, Totterdown Fields, Putney Lower Common, Roehampton Village and parts of Wandsworth Common. See the council’s Article 4 page, or send us your address.
Do I need a heritage consultant for a loft?
Only if the house is, or sits near, a heritage asset. Wandsworth then asks for a statement from a specialist consultant. We tell you at the start if that applies.
Does Wandsworth’s CIL apply to a loft?
Almost never. New-build floor area under 100 square metres is exempt unless a dwelling is created, and a loft conversion does not create one.
