Working in City of London

The City of London, the Square Mile, covers the EC2, EC3 and EC4 postcodes. Almost all of it is offices, from Victorian banking halls to modern towers, plus a small number of homes around the Barbican and Golden Lane.

Our City work is mostly for facilities managers and M&E contractors: fault-finding on lighting-control networks such as Simmtronic and DALI, adding and programming new fittings, emergency lighting, and electrical works during office refits. We often work as a subcontractor under the main contractor’s job numbers, with RAMS and a written report after every visit.

Access in City buildings is planned in advance: permits, riser access, building engineers and loading bays are all booked before we arrive, and most work is done before 7am or at weekends.

Property licensing in City of London

The City of London Corporation does not run selective or additional licensing. The only scheme is mandatory HMO licensing, for shared homes of five or more people from two or more households.

That means most flats in the City let to one household do not need a council licence, but they still need the national safety checks.

Every let still needs an EICR at least every five years, a gas safety record every year where there is gas, and working smoke and carbon monoxide alarms. Licence applications usually ask for the EICR and gas safety record, and we can provide both, with any remedial work quoted in writing first.

Licensing rules change, so always check the exact address with the City of London Corporation. Correct as of November 2026.
