What Happens During an HMO Inspection in Hounslow

You've submitted your HMO licence application, uploaded the certificates, and paid the fee. At some point during the processing period, a housing enforcement officer from Hounslow Council may schedule an inspection of the property. Knowing what they're looking for — and fixing problems before they arrive — is the difference between a straightforward licence grant and a drawn-out process with improvement notices attached.

When Inspections Happen

Not every HMO licence application triggers an in-person inspection, but the council has the power to inspect any licensable property under Part 1 of the Housing Act 2004. Inspections are more likely for:

• First-time applications (no inspection history on file)
• Properties flagged by tenant complaints
• Properties where the submitted documents raise questions (room sizes that look marginal, missing certificates, previous enforcement history)
• Renewal applications where the last inspection was several years ago

The council will normally give you advance notice and arrange a convenient time, though it also has powers to enter without notice in urgent cases (serious safety hazards).

What the Inspector Checks

Hounslow's enforcement officers use the Housing Health and Safety Rating System (HHSRS) to assess properties. The HHSRS evaluates 29 categories of hazard, but in practice, HMO inspections in Hounslow focus heavily on:

Room sizes and occupancy. The inspector measures each bedroom to confirm it meets the minimum floor area for the number of occupants — 6.51 m² for a single person, 10.22 m² for two people. Hounslow's local standards are slightly more detailed: 9–12 m² for a single room without separate living space, and ceiling height of at least 2.14 metres over 75% of the floor area. Any floor area where the ceiling is below 1.53 metres doesn't count.

Fire safety. Working smoke alarms on every storey, carbon monoxide alarms in rooms with fuel-burning appliances, clear escape routes, fire doors where required, and fire extinguishers or blankets in kitchens. For larger HMOs, the inspector will check for a compliant fire alarm system to BS 5839 and emergency lighting to BS 5266.

Kitchen and bathroom amenities. The ratios matter: one bathroom and one WC (can be combined) for up to four occupants; a separate WC with wash basin once you hit five. Kitchen size minimums are 6.5 m² for up to five sharers and 11 m² for six to ten. The inspector will check for a full cooker, a sink with hot and cold water, adequate worktop space, food storage cupboards, and a fridge-freezer.

Electrical and gas safety. The inspector may ask to see your current EICR (no unresolved C1 or C2 codes) and Gas Safety certificate on the day, even though you uploaded them with your application. They'll also look at the general condition of wiring, sockets, and gas appliances.

Heating. Every room must be capable of reaching 21°C in bedrooms and bathrooms and 18°C in common areas when it's –1°C outside. Portable gas or oil heaters are prohibited — heating must be fixed, either central heating or wall-mounted electric heaters wired into the electrical system.

Damp, mould, and structural condition. Rising damp, condensation damage, cracked walls, and rotten window frames all fall under HHSRS hazards.

What Happens If Problems Are Found

If the inspection identifies issues, the outcome depends on severity:

• Minor deficiencies may be noted as conditions on the licence — fix them within a specified timeframe and confirm completion.
• Category 2 hazards (less serious HHSRS findings) may result in an improvement notice requiring specific works.
• Category 1 hazards (serious and immediate risk to health or safety) place a legal duty on the council to take formal enforcement action. This can mean a prohibition order, an emergency prohibition order, or an improvement notice with a tight deadline — and these apply regardless of the licensing application's outcome.

Identifying problems during an inspection doesn't automatically mean your licence is refused. The council often grants the licence with conditions requiring works to be completed within a set period. But a property with serious Category 1 hazards is a different matter — the enforcement action takes priority.

How to Prepare

The best preparation is making sure the property meets the standards before you apply. Walk through the property yourself using the same checklist the inspector will:

• Measure every bedroom and record the dimensions
• Test every smoke alarm, CO alarm, and fire door
• Check that the kitchen has everything required for the number of occupants
• Confirm the EICR is satisfactory and the gas certificate is current
• Look for damp, mould, and structural defects
