TW3: letting and licensing

Hounslow Central, Hounslow East, Hounslow South, Hounslow Heath, Heston Central. TW3 covers Hounslow Central, Hounslow East, Hounslow South, Hounslow Heath, Heston Central within London Borough of Hounslow, classified here as a corporate / new-build flats postcode. The outward code also reaches Richmond upon Thames, where London Borough of Hounslow licensing does not apply: an outcode is a postal area, not a council boundary, so check the address rather than the postcode. Licensing rules depend on whether the property is a mandatory HMO, an additional HMO, or falls inside a selective licensing designation — and the practical compliance pressure varies by profile. This page brings together the national duties that always apply, local licensing context for London Borough of Hounslow, the risk profile specific to TW3, and a step-by-step checklist tailored to that profile so you can work through everything before each new tenancy.

Who rents here

Airport and corporate demand with dense sharer stock; every HMO needs a licence borough-wide.

Corporate / new-build flats

Block-style flats, new-build conversions and corporate lets predominate. Compliance pain points shift from HMO licensing to FRAEW / EWS1 evidence, EPC band uplifts in mid-2010s stock, and freeholder service-charge accuracy that landlords need to itemise to tenants.

Before you let

The pre-tenancy checklist for TW3

Work through it before the property is advertised. One missed step can block a possession ground, trigger a Rent Repayment Order or void the insurance.

  1. Confirm licensing type on the council checker

    Open the London Borough of Hounslow landlord licensing page, run the full postal address inside TW3, and capture a dated screenshot of the result for your records.

  2. Gas Safety (CP12) - annual

    Valid Gas Safety Record in place; new tenants must receive a copy before move-in and current tenants within 28 days of the check.

  3. EICR - every 5 years

    Electrical Installation Condition Report must be satisfactory. Issue C1 / C2 remedials within 28 days and keep written confirmation.

  4. EPC / MEES - band E minimum (C by 2030)

    Confirm a valid EPC and exemption status if applicable. Plan works early for the confirmed C-band MEES uplift by 1 October 2030.

  5. Deposit protection within 30 days

    Protect any deposit in TDS, DPS or MyDeposits and serve Prescribed Information; failure blocks most Section 8 possession grounds and unlocks tenant claims.

  6. Right to Rent before tenancy starts

    Run manual, IDVT or Home Office online checks for every adult occupier and keep dated evidence for the tenancy duration plus one year.

  7. Fire safety for HMO / shared lets

    Interlinked smoke + CO alarms, fire doors, emergency lighting on escape routes, PAT for supplied electricals and a recent fire risk assessment.

  8. FRAEW / EWS1 evidence for flats above 11 metres

    Where your flat is in a block above 11 m, get and keep on file the building’s External Wall Survey (FRAEW) or the legacy EWS1 form. Mortgage lenders and corporate-tenant relocation managers ask routinely; a missing form blocks resale and corporate sublets.

  9. Service-charge transparency to tenant

    For leasehold flats, itemise the freeholder’s service-charge composition in the tenancy agreement (insurance, lift, communal cleaning, ground rent). Tenants of corporate lets routinely benchmark rent vs service-charge ratios, and lack of transparency is a friction-point at renewal.

What is in force across London Borough of Hounslow

Designations are drawn by ward and sometimes by street, so a postcode is never the answer. The only authoritative source for an address in TW3 is the council’s own checker.

  • 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

Common pitfalls

What goes wrong in TW3

The mistakes that recur in corporate / new-build flats postcodes like this one.

Lease-prohibited subletting

Many corporate-block leases prohibit short-term and corporate sublets without freeholder consent. Subletting in breach voids the building insurance for the unit.

EWS1 expiry and re-survey costs

EWS1 forms are typically valid for 5 years. A lapsed form can stall a corporate-tenant relocation procurement at the credit-check stage.

Service-charge surprise increases

A sharp year-on-year service-charge increase is a common trigger for a corporate tenant to serve notice. Forecast the increase and disclose it in the tenancy agreement rather than absorbing it silently.

FAQs

TW3: the questions landlords ask

What FRAEW / EWS1 evidence do I need to let a flat in TW3 above 11 metres?

For a flat in a block above 11 m in TW3, you need either a current FRAEW (Fire Risk Appraisal of External Walls under PAS 9980) or the legacy EWS1 form (still accepted by most lenders for evidence purposes). Get the form from the freeholder — you should not pay for the building survey yourself — and keep the dated copy with the tenancy records. London Borough of Hounslow cladding-remediation status updates are also worth checking before any new corporate let.

Does TW3 fall under selective or additional licensing in London?

It depends on the exact address and property type. London Borough of Hounslow publishes a postcode or ward checker. TW3 includes Hounslow Central, Hounslow East, Hounslow South, Hounslow Heath, Heston Central. The outward code also reaches Richmond upon Thames, which is a different licensing authority. Run the full postal address on the council checker before assuming no licence is required: designations are drawn by ward or street, not by postcode.

What national UK landlord duties apply in TW3?

England-wide duties apply regardless of local licensing: Gas Safety (annual CP12), EICR every 5 years, EPC band E minimum (MEES), deposit protection within 30 days, Right to Rent checks before move-in, and smoke + CO alarm rules. Get any of these wrong and Section 21, RROs and civil penalties all follow.

Is TW3 a high-enforcement postcode area?

Student, HMO-dense and regeneration postcodes in London typically see more unannounced inspections, licence audits and follow-ups from environmental health. Keep certificates, licences and tenant documents in one place and renew before expiry. Unlicensed letting can attract civil penalties up to £40,000 and Rent Repayment Orders of up to two years' rent.

How much is a landlord licence in TW3?

The fee is set by London Borough of Hounslow for each scheme it runs, and it is usually split into an amount payable with the application and a second amount payable before the licence is granted. Some councils discount an early renewal or an accredited landlord. Where we have the current figure it is printed on the council page above; otherwise take it from the council's own fees page, because fees change between designations.

Do I need planning permission to convert into an HMO in TW3?

If the council area is subject to an Article 4 Direction for C3 to C4 use, you need full planning permission to let to 3 or more unrelated sharers. London Borough of Hounslow publishes its Article 4 map. Large HMOs (sui generis, 7+ sharers) always need planning permission.

Can I use Section 21 in TW3 after the Renters Rights Act?

No. Section 21 was abolished on 1 May 2026 across England, including London, and every assured shorthold tenancy became an assured periodic tenancy, so possession now runs on a Section 8 ground. The deposit still matters: section 215 of the Housing Act 2004, as substituted by the Renters’ Rights Act 2025, blocks a possession order while a deposit is unprotected or the prescribed information has not been given, on every ground except 7A and 14. A missing gas record or EPC does not bar a Section 8 claim, though it is an offence in its own right and a tenant can raise it in defence of a disrepair or possession case.

What insurance should I have for a let property in TW3?

Specialist landlord buildings insurance with landlord liability (often £2m+), optional contents for furnished items, loss of rent and legal expenses. For HMOs, check the insurer explicitly covers HMO use and the number of occupants - standard buy-to-let policies often exclude HMOs.
