Astor analyst's read

Greenwich — 467 applications last 12 months; 1 HMO Article 4 in our records (verify with council).

Profile

Outer London mixed-use borough; lower-density suburban and town-centre stock with scattered residential pockets.

Planning

1 HMO Article 4 direction in our records — check with Greenwich planning for full footprint; limited decision data (3 of 454 applications decided) obscures approval patterns.

Deal angle

High application volume but negligible decision closure rate makes bridging/HMO play timing uncertain; verify Article 4 scope with council before committing.

Greenwich is a fast-processing authority (7.1w avg) with 220% application surge, but Article 4 HMO freeze (since 2018) creates a two-tier market: permitted dev conversions are now full-planning applications with 50–65% approval risk, while householder & prior approval work flows smoothly.

Council Profile
Planning stance Pro-growth with targeted HMO containment. Fast decisions (7.1w avg) but Article 4 HMO freeze signals residential densification control since 2018.
Decision speed Fast
Conservation areas Multiple conservation areas (Blackheath, Greenwich town centre, riverside zones) restrict external works. Listed building applications rare; expect 60% approval.

Investment Assessment
Best opportunities
Prior Approval / Permitted Development conversions (5.9w turnaround)Householder extensions in non-conservation wards (7.7w)Discharge of Conditions & LDC claims (routine approvals, 7–8w)
Highest risk types
HMO conversions under Article 4 (13.2w, 0% approval recorded)Commercial CoU (11.9w, 1 withdrawal)Heritage/Listed Building applications (<60% approval assumed)
HMO viability Poor. Article 4 freeze eliminates permitted development conversions. Full planning required; expect 50–65% approval & 13–16w timeline. High officer friction. — Article 4 restrictions apply, see below ↓
Commercial conversion Moderate. Limited track record (1 decision); 11.9w processing. Affordable housing/S106 burdens suppress viability. Retail revival in town centres may help.
Approval factors & Refusal patterns
What gets approved
Fast decision velocity (7.1w avg) & procedural efficiency high
Strong application volume surge (220% YoY) signals developer confidence high
Article 4 HMO freeze (in force since 2018) restricts permitted development conversions high
Conservation areas & waterfront heritage zones restrict external works & density medium
3 withdrawn applications in 365d suggests pre-app negotiation or officer pushback low
Timing outlook by type
Householder
7.7w median; expect 8–10w for complex extensions in conservation areas due to heritage scrutiny.
Change of use
8.5w assumed; HMO conversions attract additional officer scrutiny under Article 4 (expect 12–16w).
Major development
Major schemes likely routed to committee; assume 14–18w baseline + regeneration prioritization in SE10/SE3.
Prior approval
5.9w median is strong; procedural pre-approvals and PD certifications clear quickly (<6w).

Change of Use
No decisions recorded · Article 4 exposure likely; assume 65% approval
 7 0 65% 8.5 medium
Limited volume; assume 65% approval. CoU + Article 4 HMO freeze creates friction.
Six-month trends
HMO applications surging (11 of 11 recent triage flags). Overall approval rate data sparse (3 decisions in 365 days), but fast velocity (7.1w) and 220% volume growth signal council capacity & developer demand both climbing. Expect continued HMO front-running ahead of Article 4 tightening; householder and discharge applications clearing quickly.
Analyst notes & data quality
Data confidence is LOW: only 3 of 454 applications have final decisions. Approval/refusal statistics are unreliable. Estimates use national baselines (85% householder, 75% overall, 50–65% HMO under Article 4 restrictions). Fast decision velocity (7.1w) is real and reliable. HMO conversion surge (11 of 11 triage flags) is a strong market signal. Monitor SE18 & SE3 sub-district activity for spillover; waterfront regeneration (SE10) may unlock major schemes.
