Houses in Multiple Occupation (HMOs) have more stringent electrical requirements than standard rental properties. If you're an HMO landlord in Bedfordshire or Hertfordshire, understanding these requirements is essential — not just for legal compliance, but for the safety of your tenants.

What is an HMO?

A House in Multiple Occupation (HMO) is a property rented by at least 3 people who are not from the same household (e.g. a family) but share facilities like the bathroom and kitchen. Larger HMOs (5 or more people from 2 or more households) require a mandatory HMO licence from the local council.

HMO Electrical Requirements 2025

Here are the key electrical requirements for HMO properties in Bedfordshire and Hertfordshire:

EICR (Electrical Installation Condition Report)

All HMOs must have a valid EICR carried out at least every 5 years by a qualified electrician. The EICR must be provided to tenants and to the local authority on request. For HMO licensing purposes, many councils require the EICR to be no more than 5 years old at the time of the licence application.

RCD Protection

HMOs must have adequate RCD (Residual Current Device) protection. Modern consumer units should have RCD protection on all circuits. Older properties with split-load consumer units may need upgrading to provide full RCD protection across all circuits.

Smoke and Heat Alarms

HMOs require interlinked smoke alarms in all rooms used as sleeping accommodation, in corridors and stairways, and in kitchens. Heat alarms are required in kitchens. All alarms must be interlinked so that if one activates, all alarms sound.

Emergency Lighting

Larger HMOs (typically those with 3 or more storeys) require emergency lighting in escape routes. Emergency lighting must be maintained and tested regularly. We can design and install emergency lighting systems that meet BS 5266 requirements.

Sufficient Electrical Sockets

HMOs must have sufficient electrical sockets in each room to prevent the use of extension leads and adaptors. As a guide, bedrooms should have at least 4 sockets, kitchens should have adequate sockets for all appliances, and communal areas should have sufficient sockets for shared use.

Electrical Safety in Communal Areas

All electrical installations in communal areas must be safe and well-maintained. This includes lighting, sockets, and any fixed appliances. Communal areas must be adequately lit, including stairways and corridors.

HMO Licensing in Bedfordshire and Hertfordshire

In addition to the national HMO electrical requirements, local councils in Bedfordshire and Hertfordshire may have additional requirements as part of their HMO licensing schemes. Here's what you need to know:

Bedford Borough Council

Mandatory HMO licensing for properties with 5+ occupants. Additional licensing schemes may apply in certain areas. Contact the council for current requirements.

Central Bedfordshire Council

Mandatory HMO licensing for properties with 5+ occupants. The council may request copies of EICRs and other safety certificates as part of the licensing process.

Mandatory HMO licensing plus additional licensing schemes in certain areas. Luton has a large HMO sector and the council is active in enforcement.

Hertfordshire Councils

Each Hertfordshire district council operates its own HMO licensing scheme. Requirements vary — check with your local council for specific requirements.

Common HMO Electrical Faults We Find

When we carry out EICR inspections on HMO properties across Bedfordshire and Hertfordshire, these are the most common issues we find:

Outdated consumer units without adequate RCD protection — very common in properties built before 2000
Insufficient sockets in bedrooms — leading to dangerous use of extension leads and adaptors
Smoke alarms not interlinked — a common HMO licensing failure
Inadequate earthing and bonding — particularly in older properties
Overloaded circuits — especially in kitchens with multiple appliances
Damaged or deteriorated wiring — particularly in properties that have been converted from single-family homes
Missing or inadequate emergency lighting in escape routes
