How these figures are counted

Homes in Hounslow

Why homes in Hounslow rate as they do

Hounslow reaches from the river at Chiswick, Brentford and Isleworth to the airport edge at Cranford, Heston and Bedfont. Strand on the Green has period houses by the Thames, and the Hounslow side of Bedford Park has Victorian villas. Hounslow, Feltham and Hanworth are mostly interwar and post-war estates, and the Brentford waterfront has newer flats.

A riverside flat and an interwar semi in Feltham are read differently. For the flat, the floor, the roof above and the heating system count. For the semi, evidence that the cavity was filled or the loft topped up helps, and so does the boiler age. Neither depends on the TW code.

31.8% of Hounslow’s certificates record insulated cavity walls, against 24.4% across London, and 19.2% are for homes built from 1991 to 2011, against 12.7%. Only 19.5% date from before 1930, and 38.6% record solid walls with no added insulation.

What the certificates record in Hounslow and across London
Recorded on the certificate	Hounslow	London
Built before 1930	19.5%	31.3%
Solid walls, no added insulation	38.6%	48.1%
Cavity walls, insulated	31.8%	24.4%
Mains gas boiler	72.5%	76.2%
Communal heating	10.2%	10.8%
Electric heating	16.6%	12.2%

On 92.5% of the certificates rated D or lower, the potential rating (every recommendation carried out) is C or better.

Letting in Hounslow: mandatory and additional HMO licensing

Hounslow runs two HMO schemes. Mandatory licensing covers HMOs of five or more people in two or more households sharing facilities. Additional licensing was designated on 11 September 2025 and applies borough-wide from 11 December 2025. It covers HMOs occupied by three or more people in two or more households, and converted-building HMOs where the building and its dwellings are in the same ownership or effectively the same control.

A licence lasts five years, but the council may issue a shorter one, normally one year, if it has concerns about management or the condition of the property or has found deliberate avoidance of licensing. It says a licence is not planning permission, which an HMO may also need.

The fee for a new or renewal licence is a base fee of £1,608, or £1,509 for an accredited landlord, plus £25 for each household in the HMO. The council charges extra for help with measuring rooms and drawing the sketch plan. The discount on that page is for accredited landlords.

The sketch plan a Hounslow HMO application asks for

Hounslow’s application asks you to upload tenancy agreements, management contracts, a sketch plan of the property, a current electrical installation report, a gas safety record, fire detection and emergency lighting test reports, certification of fire protection and building regulation completion certificates.

We draw laser-measured floor plans and can measure on the same visit as the EPC. If the plan is for a Hounslow HMO application, say so when you book.

Conservation areas, Article 4 and retrofit in Hounslow

Hounslow’s page says there are currently 29 conservation areas, and that Article 4 directions currently apply to Gunnersbury and Bedford Park. The council’s FAQ adds that permitted development rights do not apply to flats, or to houses converted to flats, so external changes to those need planning permission.

In those two areas the directions cover work on a home that fronts a highway, open space or waterway: alterations to a dwelling, porches, hardstanding, walls, gates and fences, painting the exterior and chimney stacks. Bedford Park’s appraisal records an Article 4(2) direction made on 24 July 2001, and says the original first-phase buildings that remain are listed, mostly Grade II. Gunnersbury Park Estate is described as a complete example of a 1920s garden suburb, with its first houses built in Gunnersbury Lane in 1926.

Hounslow’s retrofit guidance says that in a conservation area, building-mounted solar equipment stays permitted development if it is not on a wall fronting a highway, and so does an air source heat pump if it is not on a wall or roof fronting a highway or nearer the highway than the main building, unless an Article 4 direction or condition has removed the right. For a listed building it names draught-proofing, secondary glazing and underfloor insulation as less invasive measures.
