HMO Certificate Enquiries in Harrow
Organise the individual records needed for a Harrow HMO licence application, renewal, property inspection or management handover. Harrow's current licensing guidance says a shared property occupied by three or four people forming two or more households requires an additional HMO licence, while a qualifying HMO with five or more people follows mandatory licensing. The borough also has a section 257 route for certain converted buildings containing self-contained flats. Planning must be checked independently: an immediate borough-wide Article 4 direction has required permission for a new C3-to-C4 small HMO occupied from 12 June 2026, and a large HMO for seven or more unrelated people already needs planning permission. Send the full address, occupation date, residents, households, tenancy structure, room plan, conversion history, current inspection records, management responsibilities and deadline so the enquiry can be divided into the records actually requested rather than an assumed all-in-one HMO certificate.

Identify the shared-house, section 257 and planning routes separately
A room-by-room shared house and a converted building of self-contained flats can both be described casually as an HMO, but Harrow asks different questions about each. Start with the building form, occupation and conversion history, then match the council route and supporting documents to the precise property.
Residents, households and tenancies
List every current and proposed occupier, explain which residents form a household and state which kitchen, bathroom or toilet facilities are shared. Attach the tenancy agreement for every tenancy. Make clear whether rooms are let separately, all residents hold one agreement or a resident landlord lives at the property.
Building and conversion category
Describe whether the premises is a house, flat, maisonette, mixed self-contained and non-self-contained conversion, or a whole converted block. For a possible section 257 HMO, record the number of storeys and flats, private-rental proportion, conversion date, building-control evidence and whether the building and flats share ownership or control.
Occupation date and planning evidence
Record when the property first became occupied as an HMO, its previous C3 use, any lawful-use evidence and all planning decisions. The immediate Article 4 direction applies to a new small HMO occupied on or after 12 June 2026; starting construction earlier does not by itself preserve permitted development rights.
Management, ASB and safe access
Identify the licence holder, manager, freeholder and responsible person for common parts. Prepare Harrow's requested anti-social behaviour action plan and explain how residents report issues. Confirm keys and notice for every bedroom, kitchen, meter, electrical intake, escape route and shared installation included in the enquiry.
Harrow property type and access change between town-centre conversions and suburban shared houses
Harrow town centre, Greenhill, Wealdstone, Marlborough, West Harrow, North Harrow and South Harrow include terraces, semis, flats above commercial premises, converted houses, purpose-built estates and newer apartment blocks. Give the complete building, floor and flat reference because responsibility can stop at the dwelling door while a freeholder or managing agent controls entrance halls, risers, alarm equipment, emergency lighting or electrical intake areas. Confirm controlled parking, loading restrictions, entry-phone instructions and the name of the person authorised to open both rented rooms and shared service cupboards.
Kenton, Queensbury, Stanmore, Belmont, Pinner, Hatch End, Headstone, Roxeth and the Edgware boundary contain suburban houses, maisonettes and larger homes adapted with loft rooms, divided receptions, side or rear additions and converted garages. Compare the existing layout with the floor plan before booking; locate each gas appliance, consumer unit, alarm panel, kitchen, fire door and final exit. HA postcodes and neighbourhood names can cross into Brent, Barnet or Hillingdon, so the complete address and responsible council must be confirmed before relying on a Harrow licensing or planning rule.
Match Harrow's application list to the licence category
Harrow asks standard HMO applicants for a floor plan, gas and electrical evidence, a fire risk assessment, tenancy agreements and an anti-social behaviour action plan. A section 257 application also lists an emergency-lighting certificate. Each document must remain complete and identifiable because the council licence, planning status and safety reports answer different questions.
Gas safety certificate where applicable
Where gas is supplied, identify every landlord-controlled boiler, fire, cooker, hob, water heater, flue and meter. Provide the complete current gas safety record for the correct property and evidence for any defect or repair completed afterwards. Confirm separately any communal plant or installation controlled by another party.
Electrical installation evidence
Supply the full electrical safety certificate or EICR, including schedules, circuit details, observations and completed remedial evidence. Harrow's conditions say the periodic report should cover the whole installation and urgent or improvement items must be addressed within the relevant timescale.
Fire risk and common-part systems
Prepare a current fire risk assessment for the actual layout and occupation. Record the protected route, fire doors, detection, warning arrangements, emergency escape lighting and common parts. For a section 257 application, Harrow expressly lists an emergency-lighting certificate in addition to the fire assessment.
Floor plan, tenancies and ASB plan
Use a plan that reflects every current room, facility and final exit, then reconcile it with all tenancy agreements and the proposed maximum occupation. The anti-social behaviour action plan should explain prevention, reporting and response arrangements rather than appearing as a generic unsigned policy unrelated to the residents or manager.
Which Harrow licensing guidance and planning date apply?
Harrow Council's current licensing pages state that qualifying HMOs occupied by three or four people in two or more households require an additional licence across the borough, while qualifying five-plus HMOs require mandatory licensing. The council also describes an additional licensing route for certain section 257 buildings converted into self-contained flats. An existing additional licence does not need to be replaced under a newer scheme until that licence expires; only one property licence is required for the licensable premises.
For a standard HMO application or renewal, Harrow lists a floor plan, gas safety certificate where applicable, electrical safety certificate, fire risk assessment, tenancy agreement for every tenancy and an anti-social behaviour action plan. Section 257 applications also list emergency-lighting evidence. Planning remains separate: Harrow's immediate Article 4 direction applies borough-wide to new C3-to-C4 HMO occupation from 12 June 2026. London Landlord Certifications can organise relevant inspection enquiries but cannot determine licensing, section 257 status, planning lawfulness, room suitability or council acceptance.
Follow Harrow's building, licensing and planning decisions in order
1. Classify the premises
Confirm the number of occupiers and households, facilities shared, tenancy structure and any exemption. Decide whether the council route is additional licensing, mandatory licensing or the section 257 whole-building route for a qualifying conversion of self-contained flats.
2. Check the relevant planning date
For a C3 dwelling changing to a C4 HMO, establish whether HMO occupation began before or on or after 12 June 2026. New small HMOs from that date need permission across Harrow. Seven or more unrelated occupiers follow the larger-HMO planning route.
3. Submit a complete, consistent file
Cross-check the floor plan, tenancies, residents, licence holder, gas record, electrical report, fire assessment, ASB plan and any emergency-lighting evidence. Harrow warns that an incomplete application or missing required documents can be rejected before the council inspection stage.
Practical HMO certificate questions for Harrow properties
Is there one HMO certificate for a Harrow property?
No. Harrow Council issues the appropriate property licence. Gas, fixed-electrical, fire-risk, emergency-lighting, floor-plan, tenancy, anti-social behaviour and planning evidence remain separate documents and decisions.
When does a shared property need an additional HMO licence in Harrow?
Harrow's current guidance says qualifying HMOs occupied by three or four people forming two or more households require additional licensing across the borough. Five or more qualifying occupiers use mandatory licensing instead.
What is a section 257 HMO in Harrow?
It concerns the whole of certain buildings converted into self-contained flats where the conversion did not meet the relevant Building Regulations and the statutory ownership and occupation tests are met. Harrow's current guidance identifies buildings of three or more storeys with at least three privately rented flats under the same ownership or control.
Does a new small HMO need planning permission in Harrow?
Yes. The immediate borough-wide Article 4 direction took effect on 12 June 2026. A home newly occupied as a C4 HMO by three to six unrelated people on or after that date needs planning permission. Existing small HMO occupation before the date is treated differently, so retain evidence of the actual use.
What does Harrow request with an HMO licence application?
The council lists a floor plan, gas safety certificate where applicable, electrical safety certificate, fire risk assessment, every tenancy agreement and an anti-social behaviour action plan. A section 257 application also lists an emergency-lighting certificate.
Need to prepare a Harrow HMO licensing evidence file?
Send the complete Harrow address, occupier and household schedule, shared facilities, tenancy structure, building and conversion type, HMO occupation date, floor plan, licence or renewal request, planning information, gas, electrical and fire records, ASB plan, emergency-lighting evidence where relevant, management contacts, access restrictions and required date. We can then route the applicable inspection enquiries without presenting the licence or planning decision as part of a certificate bundle.
