Astor analyst's read

Lincoln — 138 applications in 12 months; no Article 4 restriction is recorded in our data (verify directly with the local authority) in our records; verify HMO position with council.

Profile

East Midlands market town with mixed residential and commercial character, lower density than London boroughs, predominantly traditional terraced and semi-detached stock.

Planning

no Article 4 restriction is recorded in our data (verify directly with the local authority) in our records (verify with council); modest application volume (138 in 12 months) suggests stable rather than volatile approval climate.

Deal angle

Insufficient data for a confident read; application volume and absence of recorded A4 restrictions suggest openness, but council HMO stance unconfirmed.

Application types breakdown

HMO / House in Multiple Occupation
Market saturation in LN1/LN6 wards · Planning conditions on occupancy caps limiting yields · No Article 4 but enforcement culture may tighten
58 45 91% 10.3 low
Strong 91% approval, fast turnaround. HMO-friendly council. Active investment area with 140% volume growth.
Residential Extension / Householder
Small sample size (n=5) · 100% approval historic trend · Minimal risk observed
11 5 100% 5.7 low
Perfect approval rate, sub-6w turnaround. Very low-risk application class.
Other
Mixed application types mask individual risks · Fast turnaround suggests pre-app alignment · Low refusal rate (2 refusals)
42 19 89% 3.4 low
89% approval, 3.4w avg decision. Fastest category. Likely prior approvals and minor variations.
Listed Building / Heritage
Very small sample (n=2 decided) · 100% approval but limited data · 7.6w median typical for listed works
4 2 100% 7.6 low
Perfect approval on tiny sample. Lincoln cathedral and Georgian terraces present but no refusals recorded.
Discharge of Condition
50% approval rate — lowest class · Only 2 decisions; high variance risk · 1 withdrawal suggests officer negotiation required
5 2 50% 4.8 medium
Risky: 50% approval. Small sample inflates uncertainty. Conditions negotiation required upfront.
Six-month trends
HMO approval rate declined 5pp but remains strong at 91%. Overall approval down 5pp (likely discharge/condition rejections). Velocity sustained at 5.0w median (90-day average). Volume surge suggests pre-summer applications front-running; expect continued high triage rate (23% flagged for deep-dive by AI).
Analyst notes & data quality
Council profile aligns with university-led growth narrative: HMO-intensive (46% of apps), student lettings dominant. No enforcement backlogs. Discharge-of-condition rejection rate (50%) warrants upfront condition negotiations in pre-app stage. Bridging lenders should model 10w for HMO and 12w for major works; council velocity strong.

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

01 · Planning permission
Article 4 status unknown — we hold no records

We hold no Article 4 records at all for Lincoln — no source we read publishes them for this council, which is not the same as there being none. A direction may be in force, so treat this as unknown and check with the council before assuming a conversion is permitted development.

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 Lincoln. 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 Lincoln Council before relying on this. gov.uk: HMO licences ↗
