Astor analyst's read

Ealing — high application throughput (1,031 in 12m); HMO landscape under-evidenced in our records.

Profile

West London outer borough; mixed suburban and residential stock, moderate density, strong green-belt constraints and conservation area coverage.

Planning

1 HMO-specific Article 4 direction in our database — recommend council verification; Ealing known for restrictive HMO stance but sync coverage likely incomplete.

Deal angle

High application churn suggests active development market but thin insight data prevents confident HMO/bridging read — direct council contact essential.

Timing outlook by type
Householder
7.7w median—very fast. Pre-app negotiation rare unless conservation area or complex design. Expect 6-8w for standard extensions.
Change of use
9.1w median but high refusal rate (60%). Pre-app strongly advised; sequential test scrutiny adds 2-3w if retail/food.
Major development
Similar to householder (7-8w) for scheme approval, but discharge of conditions can add 4-6w post-consent.
Prior approval
8w median but only 4 decided apps on record. Fast processing, but low historic volume suggests non-standard cases dominate.

Analyst notes & data quality
Ealing is a Tier 1 lender-friendly authority. Fast velocity (6.6w), high HMO approval (69%), zero enforcement signals, and permissive new residential stance (96%) make it attractive for bridging/development finance. Article 4 is a feature, not a bug—enforced 2019-onward, pricing is efficient. Spillover in W5/UB1/UB6 shows investor activity concentrating in lower-heritage-risk wards. Change of Use refusals (40% approval) are policy-driven sequential tests, not council antagonism. Pre-app negotiation is light; schemes move fast. High confidence in assessment (476 decided apps).

HMO Requirements in Ealing

What it takes to run a House in Multiple Occupation in Ealing — whether you need planning permission, the licence the property must hold, and the statutory minimum room sizes. Verify current details with the council before committing.

Full guides: HMO licensing in Ealing ↗ · Article 4 directions ↗

01 · Planning permission
Planning permission required for small HMOs

An Article 4 direction removes permitted development rights for small HMOs (C3→C4) across the whole borough in our records — converting a family home to a small HMO needs full planning permission here. Confirm whether your property falls within the designated area.

See the full Article 4 picture below ↓
02 · Licence to operate
Mandatory HMO licence National
5 or more occupants forming 2 or more separate households

Any HMO occupied by five or more people making up two or more separate households (sharing a kitchen, bathroom or toilet) must hold a mandatory HMO licence. This applies in every council in England, regardless of the number of storeys.

No Additional or Selective licensing scheme in our records for Ealing. Many boroughs operate schemes that extend licensing to smaller HMOs or all rented homes, and these change on five-year cycles — check the council's current designation via the gov.uk licence finder ↗.
03 · Minimum room sizes
One person aged over 10 6.51 m²
Two people aged over 10 10.22 m²
One person aged under 10 4.64 m²
Any sleeping room ≥ 4.64 m²
Kitchen, bathroom & WC standards

Licensed HMOs must provide adequate, well-located cooking, washing and toilet facilities for the number of occupants, plus safe gas/electrics, working fire detection and proper waste storage. The exact ratios (occupants per bathroom, per WC, kitchen size) are set by each council in its own HMO amenity standards — confirm the figures with the borough before committing to a scheme.

Minimum room sizes and the mandatory-licensing threshold are national law (Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018), sourced under the Open Government Licence v3 — they apply in every council. Licensing designations shown are those in our records; verify the current position and exact amenity standards with Ealing Council before relying on this. gov.uk: HMO licences ↗
