Letting in the City of London: HMO licensing

The City of London Corporation’s page for landlords says properties with five or more tenants from two or more households must be licensed. The pages we read describe mandatory licensing only, and say a licence is granted if the holder is fit and proper, the property and tenancy are managed appropriately and the accommodation meets minimum standards.

Running a house in multiple occupation without a licence is a criminal offence, with a fine of up to £20,000 mentioned together with other measures. The council’s HMO page, last updated on 16 February 2023, lists an initial fee of £600 on application and a fee on grant that depends on the number of lettings: £450 for up to five, £600 for six to nine, £750 for ten to fourteen, £900 for fifteen to nineteen and £1,050 for twenty or more. That page is dated, so confirm the current fee with the Environmental Health team.

Homes in City of London

Why homes in City of London rate as they do

There are very few houses in the Square Mile. Homes here are flats: the Barbican Estate and Golden Lane Estate, a scattering of older blocks and conversions of former offices and warehouses, and new residential towers among the commercial buildings. A flat is often a studio or one bedroom.

In a large block the building decides most of the rating, so the details that matter are the communal heating or cooling system, the controls in the flat and the glazing. For a listed estate flat, the original windows and fixtures are part of what the assessor records, and they are not always what a newer flat would have.

42.5% of certificates record system-built walls, against 8.8% across London, and 43.3% record communal heating, against 10.8%. Mains gas heats 19.6%, and electric heating 33.5%. Homes from 2012 onwards are 15.8%.

Mains gas boiler	19.6%	76.2%
Communal heating	43.3%	10.8%
Electric heating	33.5%	12.2%

On 65.7% of the certificates rated D or lower, the potential rating (every recommendation carried out) is C or better.

The City Corporation announced a competition for Golden Lane Estate in 1951, and the estate was completed in 1962. On completion it had 559 flats and maisonettes. The conservation area document lists Crescent House as Grade II* and the Golden Lane Estate landscape as Grade II.

The Barbican Listed Building Management Guidelines were written to help residents and planning officers judge what work needs listed building consent. For a flat in either estate, check the guidelines before changing windows or fixtures that an EPC suggests.
