Running an HMO in Tower Hamlets, Newham or Hackney? Electrical compliance is one of the most scrutinised aspects of HMO licensing. Here's the complete guide to staying compliant in 2026.

Houses in Multiple Occupation (HMOs) are subject to stricter electrical safety requirements than standard rental properties — and in East London, where Tower Hamlets, Newham and Hackney councils have some of the most active HMO licensing enforcement teams in the country, getting electrical compliance right is not optional. A single non-compliance finding can result in a licence refusal, a civil penalty of up to £30,000, or a Rent Repayment Order from tenants.

What Is an HMO and Which Properties Are Affected?

An HMO (House in Multiple Occupation) is a property rented by three or more people who form more than one household and share facilities such as a kitchen or bathroom. In practice, this covers the vast majority of shared houses and bedsit-style properties across East London. Mandatory HMO licensing applies to properties with five or more occupants forming two or more households — but many London councils, including Tower Hamlets and Newham, operate additional licensing schemes that extend requirements to smaller HMOs.

Electrical Requirements for Licensed HMOs in East London

5-Year EICR (Electrical Installation Condition Report)

All licensed HMOs must have a valid EICR carried out by a qualified and competent person at intervals of no more than 5 years. This has been a requirement for mandatory HMOs since 2007 — predating the 2020 regulations that extended EICR requirements to all private rentals. The EICR must be provided to the council as part of the licensing application and to tenants within 28 days of the inspection.

Smoke and Heat Detectors

HMOs require interlinked smoke alarms on every floor and in every room used for sleeping. Heat detectors are required in kitchens. The specific requirements vary depending on the size and layout of the HMO, but the general principle is that every occupant must be able to hear an alarm from any part of the property. Mains-powered interlinked alarms are strongly preferred by licensing authorities over battery-operated alternatives.

Emergency Lighting

Larger HMOs — particularly those with three or more storeys — are typically required to have emergency lighting in communal areas, stairwells, and escape routes. Emergency lighting must activate automatically in the event of a mains power failure and provide sufficient illumination for safe evacuation. This is a common area of non-compliance that our team identifies and rectifies during HMO electrical inspections.

Consumer Unit and RCD Protection

HMOs must have a modern consumer unit with appropriate RCD protection for all circuits. Older consumer units without RCD protection are a C2 finding on an EICR — meaning they're potentially dangerous and must be rectified before the EICR can be Satisfactory. Many older East London HMOs have consumer units that are 20–30 years old and require upgrading as part of the licensing process.

Security Lighting

Many HMO licensing conditions in Tower Hamlets and Newham now reference adequate external lighting as a requirement. Professionally installed mains-wired security lighting at entrances and communal areas is the most straightforward way to meet this requirement — and provides genuine safety benefits for tenants accessing the property at night.

Common HMO Electrical Compliance Failures in East London

• Expired EICR — the most common reason for licence refusal or enforcement action
• Absence of interlinked smoke alarms — battery-operated non-interlinked alarms are not sufficient
• No heat detector in the kitchen — required in all HMOs
• Outdated consumer unit without RCD protection — C2 finding on EICR
• No emergency lighting in communal areas and stairwells (larger HMOs)
• Inadequate earthing or bonding — particularly in older Victorian properties
• Overloaded circuits — common in HMOs where electrical demand has increased over time
• No security lighting at entrances — increasingly required by licensing conditions

What Happens If Your HMO Fails an Electrical Inspection?

If your HMO EICR returns an Unsatisfactory result (C1 or C2 codes), you must carry out all remedial works within 28 days (or sooner if specified in the report) and provide written confirmation to the council. Failure to do so can result in a Civil Penalty of up to £30,000, a Rent Repayment Order from tenants, or revocation of your HMO licence.
