Licensing in London Borough of Hounslow

Schemes are designated for a fixed period and are redesignated, widened or dropped. Treat this as the shape of the local regime and confirm the current designation on the council’s own licensing page before you let.

  • Additional HMO licensing was designated on 11 September 2025 and applies borough-wide from 11 December 2025, under a 2025 to 2030 designation
  • It covers every HMO under section 254 of the Housing Act 2004 occupied by three or more people in two or more households
  • It also covers section 257 converted buildings, but only where the building and all the dwellings in it are in the same ownership, or are effectively under the same control
  • Mandatory HMO licensing continues for five or more people in two or more households sharing a kitchen, bathroom or toilet
  • A licence is not planning permission: an HMO may need both

National duties

The duties that apply here whatever the council does

If you get it wrong

What letting without a licence costs

These are statutory, not local. A council that has designated a scheme can use all three, and a tenant can bring the second one without the council being involved at all.

Civil penalty
Up to £40,000Imposed by the council itself, without a prosecution. Serious or repeated breaches sit at the top of the range.
Rent Repayment Order
Up to 2 years’ rentThe tenant, or the council, applies to the First-tier Tribunal to have rent paid back. It is separate from the penalty above, not instead of it.
Prosecution
Unlimited fineLetting an unlicensed HMO, or breaching a licence condition, is a criminal offence and can be prosecuted rather than penalised.

Check your address

Three steps before you let the property

Designations are drawn by ward and sometimes by street, so the only answer that counts is the one for your address.

  1. Put the address into the council’s own checker

    It is the only source that is definitive for this borough, and it is the one the council will hold you to.

  2. Check the property against the national thresholds

    Mandatory HMO licensing is national, not local: five or more occupants forming two or more households need a licence wherever the property is, with no local scheme required.

  3. Get the evidence together before you apply

    Most applications ask for the same documents you already owe the tenant: the gas safety record, the EICR, the EPC, and the fire detection and escape arrangements for an HMO. The council’s list is the one that counts, but nothing on it will be a surprise if those are current.
