Licensing: Hounslow Council’s “HMO licensing” page, checked 22 October 2026. EPC figures: ONS, “Energy efficiency of housing in England and Wales” (28 October 2025), the latest certificate for each home lodged in the ten years to March 2025, at the score when it was assessed; homes without an EPC are not counted.
Hounslow licenses every shared home
Hounslow runs two HMO licensing schemes. The national mandatory scheme covers homes with five or more people forming two or more households who share facilities such as a kitchen, bathroom or toilet. Hounslow’s own additional scheme, designated on 11 September 2025 and in force across the whole borough from 11 December 2025, covers every house in multiple occupation with three or more people in two or more households, and converted-building HMOs where the building and all the homes in it are in the same ownership or effectively the same control. The designation runs from 2025 to 2030.
A licence lasts five years, but the council will normally issue a one-year licence if it has concerns about the management or condition of the property, or finds that licensing was deliberately avoided. Each licence sets the maximum number of people who can live there. Operating an HMO without a licence that is needed is a criminal offence: it can lead to prosecution with an unlimited fine, a financial penalty of up to £30,000, rent repayment orders and a place on the rogue landlord database. Planning permission for an HMO is a separate matter that you may also need. Checked on Hounslow Council’s HMO licensing page on 22 October 2026.
The EPC alongside the licence
A licence and an EPC are separate requirements. A home let to a household needs a valid certificate, and most privately rented homes must be rated E or above unless an exemption has been registered (landlord guide); for shared homes, the HMO guide explains when one is needed. Because each licence sets an occupancy limit, it helps to know the size of every room: a laser-measured floor plan records them, from £123 with the EPC in one visit.
What the assessment looks at in a Hounslow home
How homes in Hounslow score today. The ONS’s latest figures use each home’s most recent EPC lodged in the ten years to March 2025. The typical (median) score here is 71, band C, against 70 across London, and 60% of those homes are rated C or above (London 58%). Homes built before 1929 have a median of 63, against 84 for homes built since 2012; flats and maisonettes come out at 75, terraced houses at 67. How every London borough compares.
54.0% of Hounslow households live in a house — 28.6% in a semi and 20.5% in a terrace — and 45.8% in a flat.
Chiswick and Bedford Park
Chiswick is a mixture of Georgian, Victorian and Edwardian housing. Bedford Park, begun in 1875 on the Chiswick and Acton border with Queen Anne Revival houses by Norman Shaw and other leading architects, has been described as the world’s first garden suburb, and is protected by conservation areas in both Hounslow and Ealing. Period houses like these usually have solid walls and original windows, recorded as found, and in a conservation area changes to the outside can need permission — worth knowing before you act on an EPC’s recommendations.
The Great West Road suburbs
The Great West Road, completed in 1925, brought factories and a great deal of new housing to Hounslow and Heston, and from the 1930s new homes replaced Feltham’s market gardens. Older Feltham streets, such as Hanworth Road, have Victorian and Edwardian terraces, semis and detached houses, and Feltham Pond is a small conservation area. For houses of the 1920s and 1930s, the cavity walls, loft insulation and any later extension decide most of the rating.
Brentford’s waterfront
Brentford’s old warehouses and docks have been regenerated into shops, townhouses and apartments, including Brentford Dock, and flats are now the majority in both its wards; in Isleworth, the Victorian workhouse buildings have been largely redeveloped as homes. A flat built or converted in the last ten years probably already has an EPC — check its date before booking a new one.
Selling in Hounslow
45.7% of Hounslow households own their home. A sale needs an EPC ordered before the home is marketed — the sellers’ guide explains the timing.

Common questions

How long does a Hounslow HMO licence last?
Five years, though the council will normally issue a one-year licence where it has concerns about the management or condition of the property, or has found deliberate avoidance of licensing.
What is the penalty for an unlicensed HMO in Hounslow?
Prosecution with an unlimited fine, or a financial penalty of up to £30,000, as well as rent repayment orders and being added to the rogue landlord database.
Do you cover Bedford Park?
Yes. Bedford Park, begun in 1875 and described as the world’s first garden suburb, is protected by conservation areas in Hounslow and Ealing, so check with the council before changing the outside of a house to improve its rating.
