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

If Hounslow licenses your house as an HMO, keep the licence with the let.

LetCompliance holds it on the property beside the tenancy and the rent: the type, the council’s reference, the dates and how many people it allows. It emails you 90, 30 and 7 days before the licence runs out, and warns you if a tenant moving in would put more people in the property than the licence permits.

Wards and postcodes

What each postcode here covers, ward by ward

The four outward codes on this guide touch 23 electoral wards between them. Every one of them crosses a council boundary (TW3 into Richmond upon Thames; TW7 into Richmond upon Thames; TW8 into Ealing; TW13 into Richmond upon Thames), and nothing Hounslow designates applies on the far side of it. Wards from the ONS postcode directory, checked 18 September 2026. Designations follow ward and sometimes street boundaries, so knowing the ward narrows it down; the council’s own designation is the answer for the address.

Local rents

What lets for in London Borough of Hounslow

Office for National Statistics, August 2026 (released 16 September 2026): the average private rent on new and existing tenancies. A council average is not the market rent of a particular home.

PRS Database

When landlords in Hounslow must register

Hounslow is in the London region. Registration becomes required there on 15 July 2027, and the deadline is 14 October 2027. Every let home in England goes on the new Private Rented Sector Database, and the date is set by where the property is, not where you live. Everything for London.

  1. Opens to everyone

    Any property can be registered early, wherever it is.

  2. Required in London

    The three-month window to register starts.

  3. Deadline

    After this date the council can take enforcement action.

The fee is £65 a year for each property, pro-rated during the rollout. Miss the deadline and the council can impose a penalty of up to £7,000. While a let that should be registered is not, a court cannot make a possession order for it, except on the antisocial behaviour Grounds 7A and 14 (Renters’ Rights Act 2025, section 90). Dates from the GOV.UK Housing Hub, checked 23 September 2026.

Get ready in LetCompliance

Seventeen answers a property. Have them on one page before 15 July 2027.

The register asks the same 17 things about every home you let, from the number of households to copies of the gas safety record, the EICR and the EPC. LetCompliance builds a register pack for each property from the records you keep in it: what is ready, what is missing, and the certificate files to upload. Registering becomes copying from one page.

  • A register pack for every property

    All 17 items, most of them filled in from the tenancy, rent, licence and certificate records you already keep.

  • The gaps, said plainly

    Each gap links to the page where you fill it in, so they are closed weeks ahead, not on the deadline.

  • Reminders on the London dates

    An email the day registration becomes required, then 30 and 7 days before 14 Oct 2027, for every property not yet marked registered.

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. Check the address on the council’s own licensing pages

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

    London Borough of Hounslow licensing

  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.

    Free postcode licensing checker

  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.

National duties

The duties that apply here whatever the council does

A licence sits on top of these, it does not replace them. Renewal cycles and maximum penalties are the same in every England council area.

Each row links to the full duty: what it obliges you to do, what happens when it is missed and the practical way to stay on top of it. Read the national guide.

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.

FAQs

London Borough of Hounslow: the questions landlords ask

Does a 3-person share in Hounslow need a licence?

Yes. Since 11 December 2025 the borough-wide additional scheme covers any HMO occupied by three or more people in two or more households, so a three-person share needs a licence.

Is the application different for additional and mandatory licences in Hounslow?

No. The council states that the application process is the same for both mandatory and additional HMO licences.

When do landlords in Hounslow have to register on the PRS Database?

Hounslow is in the London region. Registration becomes required there on 15 July 2027, and the deadline is 14 October 2027. Any property can be registered earlier, from 15 December 2026. The fee is £65 a year for each property, and the date follows where the property is, not where the landlord lives. While a let that should be registered is not, a court cannot make a possession order for it, except on the antisocial behaviour grounds.
