Bexley planning rules baked into your building regs 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.

The questions homeowners ask before they commit.
When do I need building regulations drawings in Bexley?
Almost any structural alteration in Bexley triggers Building Regulations — extensions, loft conversions, internal load-bearing wall removal, new bathrooms, replacement boilers above 5kW, electrical work in special locations. Building regs is independent of planning permission; you can need one without the other, but most Bexley projects need both.
What do Bexley building regs drawings cost?
A full building regulations package for a Bexley extension or loft is £1,200 – £3,400 fixed, including structural calculations (Part A) and the application fee. Bigger schemes — basements, multi-storey rear extensions, change of use — sit at the upper end. Standard houseshare/HMO compliance is quoted separately.
Do I submit to London Borough of Bexley or use an Approved Inspector?
Both routes are valid in Bexley. London Borough of Bexley Building Control is the default — typically £900 – £1,800 LPA fee plus on-site inspections. Approved Inspectors (private sector) often turn around plans-check faster but cost similar. We submit either route; preference is usually decided by your builder's site relationship.
What Approved Documents apply to my Bexley project?
Standard residential extension hits: Part A (structure), Part B (fire), Part C (site / damp), Part E (sound), Part F (ventilation), Part H (drainage), Part K (stairs / falls), Part L (thermal / fabric), Part M (access), Part O (overheating), Part P (electrical) and Part R (broadband). Our drawings call out compliance with each on the relevant sheet.
How long does plans-check take in Bexley?
London Borough of Bexley plans-check is statutorily 5 weeks; conditional approval often arrives at 3–4 weeks. We respond to plans-checker queries the same working day. Site inspections start at strip-out / foundation and run through to completion certificate — usually 4–8 inspections on a standard Bexley extension.
Are structural calculations included?
Yes. Every Bexley building regs package on the TradeMatch panel includes structural calculations to Part A — beams, lintels, foundations, party-wall structural notes — produced by a chartered structural engineer (CEng MIStructE) and signed off before submission. No surprise bills mid-project.
