Building regs from £950. We do not charge hourly. Free site survey across all SE6 addresses.
From first call to planning decision: typically 12–14 weeks. Site survey week 1, design weeks 2–3, validation 1–2 weeks, statutory 8-week determination. Lewisham Council timelines align with the national norm.

Every SE6 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. SE6 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| SE6 | Catford / Bellingham | 1930s semi-detached, post-war flats | SE6 covers Catford / Bellingham only; Lewisham Council handles the drawing package. |
| SE6 | Catford | 1930s semi-detached, post-war flats | Catford sits inside SE6; drawing package proposals here are determined by Lewisham Council. |
| SE4 | Brockley | Victorian and Edwardian terraces | Adjoining district to SE6, also inside Lewisham for drawing package purposes. |
| SE8 | Deptford | Georgian terraces, post-war estates, new-build | Adjoining district to SE6, also inside Lewisham for drawing package purposes. |
| SE12 | Lee / Grove Park | mixed stock | Adjoining district to SE6, also inside Lewisham for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few SE6 streets, and each one changes what a drawing package can achieve at that address.
Conservation areas covering SE6 (Catford / Bellingham): Lewisham Council runs 30, and Blackheath, Deptford High Street, Forest Hill are the ones SE6 (Catford / Bellingham) owners meet most. A drawing package inside a SE6 (Catford / Bellingham) conservation area loses permitted development, so the SE6 (Catford / Bellingham) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Blackheath a drawing package is judged on the street elevation first.
No blanket Article 4 over SE6 (Catford / Bellingham): Lewisham Council has not withdrawn permitted development across SE6 (Catford / Bellingham), so a drawing package outside a SE6 (Catford / Bellingham) conservation area usually keeps it.
