- Fee guide
- Base fee of £1,550 per property, plus £25 per household residing in the HMO. For example, a property with 3 households pays £1,550 + (3 × £25) = £1,625. An additional fee applies for assistance with measuring rooms and providing a sketch plan. The council splits the fee into Part A (costs of determining the application, inspecting the property, and issuing the licence) and Part B (costs of enforcement against unlicensed operators and monitoring compliance). £95 discount for accredited landlords or accredited managing agents who are members of a recognised accreditation scheme, including the London Landlord Accreditation Scheme (LLAS), NLA/NRLA, RLA, ARLA/PropertyMark, NALS, RICS, or UKALA.

Research notes
Designated on 11 September 2025 following a Cabinet decision on 2 September 2025. Consultation ran from 12 March to 21 May 2025 and produced an evenly split result: 47.9% of respondents supported renewal, 47.9% opposed, 4.2% unsure. Despite the tied outcome, Cabinet voted to renew the scheme. This is the second consecutive five-year additional licensing designation in Hounslow; the previous scheme ran from 1 August 2020 to 31 July 2025. There was a gap period from 1 August 2025 to 10 December 2025 (approximately 4.5 months) during which no additional licensing scheme was in force. Applications for the new scheme were encouraged to be submitted before 11 December 2025. During the first four years of the previous additional scheme (2020–2024), 40% of all HMO licence applications received were for discretionary (additional) licences. As at April 2025, approximately 1,236 properties were listed on the public register. Property types covered: All HMOs as defined by section 254 of the Housing Act 2004 occupied by three or more persons in two or more households sharing facilities (kitchen, bathroom, or toilet), including small HMOs with 3–4 occupants not captured by mandatory licensing. Also includes Section 257 HMOs: buildings converted into self-contained flats where the conversion did not comply with Building Regulations, and the building and all dwellings are under unified or effectively the same ownership or control. Purpose-built flat blocks of three or more self-contained units are excluded.. Exemptions or exclusions: Multi-occupied purpose-built self-contained flats in blocks comprising three or more self-contained flats are excluded. Properties meeting mandatory HMO licensing thresholds (5+ occupants) require mandatory licensing instead. Standard national exemptions under the Housing Act 2004 apply..
