About this application

This is a planning application for a new dwelling at 101 Cornwall Avenue Southall UB1 2TQ. Ealing has handled 13,320 applications of this type. This one was decided in 63 days, 7 days longer than Ealing's typical decision time. There has been 1 other application at this address. We hold 2,273 applications in total for the UB1 postcode area.

Why it was refused

  1. The application was submitted on 2 June 2026, and the applicant claims that the property has been in continuous use as a 5-bedroom House in Multiple Occupation (HMO) since 29 July 2016. However, this falls approximately eight weeks short of the required 10-year period. Furthermore, the evidence submitted is insufficient to demonstrate, on the balance of probabilities, that the property at 101 Cornwall Avenue, Lady Margaret, has been in continuous use as a 5-bedroom House in Multiple Occupation (HMO) accommodating up to 10 persons (sui generis) for at least 10 years immediately preceding the date of the application. Accordingly, the Local Planning Authority is not satisfied that the use has become lawful through the passage of time and the use is therefore not considered lawful under Section 191(2)(a) of the Town and Country Planning Act 1990 (as amended).

From the council's decision notice.
