Bexley planning rules baked into your planning drawings.
Bexley is an outer south-east London borough where most planning work happens in suburban semi-detached stock around Sidcup, Bexleyheath, Welling, Erith, Crayford and Belvedere. Compared with inner London, householder permitted-development rights are broadly intact — but a borough-wide HMO Article 4 (since 24 September 2017), recent Class E → C3 Article 4 Directions covering designated town centres (10 December 2025) and industrial locations (8 January 2025), plus Article 4(2) Directions in Brook Street, Old Bexley, Old Forge Way and Red House Lane conservation areas, mean change-of-use and CA-adjacent works will need a full application. With 23 conservation areas and listed assets such as Hall Place, heritage scrutiny is real around Old Bexley, Sidcup village and the Erith riverside.

What homeowners often miss
Outer suburban south-east London borough; 23 conservation areas concentrated around Old Bexley, Sidcup, Erith and Belvedere; Article 4(2) Directions in Brook Street, Old Bexley, Old Forge Way and Red House Lane CAs; borough-wide HMO Article 4 since 2017; recent Class E → C3 Article 4 Directions covering town centres (Dec 2025) and industrial locations (Jan 2025); Thamesmead / Belvedere riverside regeneration corridor; Hall Place & Gardens and Crayford historic core add heritage sensitivity.
The questions homeowners ask before they commit.
How long does a planning application take in Bexley?
The London Borough of Bexley statutory determination period is 8 weeks for householder applications and 13 weeks for major schemes. Add 2–3 weeks for validation in Bexley and 4–6 weeks for pre-application advice (recommended in any Conservation Area). We submit promptly and respond to officer queries the same working day.
How much do planning permission drawings cost in Bexley?
A standard Bexley householder planning drawings package is £950 – £2,400 fixed. Bexley-specific factors — conservation area, listed building, party-wall implications, basement-impact assessments — can lift the fee. We quote fixed-price after a free 15-minute review of the brief and Bexley planning context.
Do I need planning permission for an extension in Bexley?
Most rear extensions in Bexley fall within Permitted Development under Class A — but Article 4 Directions and Conservation Area designations frequently remove that right. We check London Borough of Bexley's A4D register and the local plan against your property before quoting, so you do not start drawings on the wrong route.
What does the Bexley planning portal need from me?
London Borough of Bexley's validation list typically requires: existing & proposed plans (1:50 / 1:100), elevations, site location plan (1:1250), block plan (1:500), design and access statement (when required), heritage statement (Conservation Area or listed building), and the application fee. We package and submit the full set on your behalf via the Bexley planning portal.
Will Bexley's Conservation Areas affect my application?
Yes — Bexley Conservation Areas trigger heritage scrutiny on materials, fenestration and roof additions. Rooflights, render changes, replacement windows and front-elevation works almost always need full planning permission inside a CA. Our drawings include a heritage justification matched to London Borough of Bexley's adopted character appraisal.
Can you handle the planning submission and officer queries for me?
Yes. For every Bexley planning application we run validation chase, planning portal upload, case-officer liaison and same-day response to written queries — all included in the fixed fee. You only step in when the officer requests a substantive design change.
