HMO landlord responsibilities go well beyond those of a standard let. This houses in multiple occupation landlord guide explains your responsibilities, from licensing and safety checks to how you charge for energy, and how the Renters’ Rights Act 2025 has changed the picture since 1 May 2026.
What Is a HMO Property?
A house in multiple occupation (HMO) is a property where at least three tenants live, forming more than one household, and share a toilet, bathroom or kitchen. A household is a single person, or members of the same family living together.
Any HMO occupied by five or more people forming more than one household must have a licence, which you can apply for through GOV.UK.
When Do You Need a HMO Licence?
A mandatory HMO licence applies to large HMOs. A property is defined as a large HMO when five or more tenants who form more than one household share the property and its facilities, and at least one tenant pays rent.
Some councils also license smaller HMOs, so check with your local authority before you let.
HMO licences last a maximum of five years. Each HMO needs its own licence, and running a licensable HMO without one is a criminal offence. There are different rules for HMOs in Scotland.
HMO Landlord Legal Responsibilities
HMO regulations sit on top of the regular duties every landlord has. As a checklist, the HMO rules for landlords mean you must:
- hold a licence if your HMO needs one and stick to its conditions
- provide the minimum bedroom sizes and number and location of shared bathrooms and kitchens, and ensure the property isn’t overcrowded
- give every household your name, address and phone number, and display them prominently
- keep fire escape routes clear, provide working smoke alarms and carbon monoxide alarms, and have a fire risk assessment carried out
- ensure electrical and gas safety standards are met and arrange an annual gas safety check and an Electrical Installation Condition Report at least every five years, keep a record of both, and supply them to the council within a week if requested
- keep the water supply and drainage in good working order, protecting fittings from frost
- keep the exterior and interior of the property, including shared areas, safe, clean and well maintained
- have an up-to-date assessment of legionella risk in the water system
- provide enough bins and arrange rubbish disposal
Fire Safety
HMO fire safety requirements are much stricter than those for standard rental properties.
Under the Management of Houses in Multiple Occupation (England) Regulations 2006, you must keep every escape route free from obstruction and in good repair and keep fire alarms and firefighting equipment in good working order. Where five or more people live in the HMO, notices showing the escape routes must be clearly displayed.
You must also fit a smoke alarm on every storey with living accommodation and a carbon monoxide alarm in any room with a fixed combustion appliance other than a gas cooker. The Regulatory Reform (Fire Safety) Order 2005 applies to the shared areas of a HMO, so you need a fire risk assessment covering them, ideally carried out by a qualified professional.
Beyond these minimums, HMO fire safety requirements depend on the size and layout of the property. Your licence conditions can set further requirements, such as interlinked alarms, heat detectors in kitchens, fire doors, emergency lighting or fire extinguishers, so check your licence and ask your council what applies to your property.
Electrical Safety: EICR
An EICR is an Electrical Installation Condition Report. It deals with the condition of the fixed electrical installation at the time it is inspected and tested. During an EICR, qualified electricians systematically check the safety of electrical wiring, consumer units and connections.
Under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, as amended, the HMO EICR must be carried out by a qualified person at least every five years. Existing tenants must get a copy within 28 days, and new tenants before they move in.
Any remedial work must also be carried out within 28 days of the inspection, or within a shorter period if stated in the report.
HMO electrical safety checks may pick up signs of interference at the meter, but a HMO EICR shouldn’t be relied on to detect energy theft. Around the meter, the inspection is visual, covering the incoming service cable, main fuse, meter tails and earthing arrangements, and some forms of energy theft wouldn’t show up from that alone.

Gas Safety Certificate
HMO gas safety falls under the Gas Safety (Installation and Use) Regulations 1998. HMO landlord responsibilities include making sure pipework and every gas appliance and flue you provide are safely installed and maintained by a Gas Safe registered engineer.
A Gas Safe registered engineer must check every gas appliance and flue you provide within 12 months of installation and every 12 months after that. Give existing tenants a copy of the HMO gas safety check within 28 days of the check, and new tenants a copy before they move in.

The Renters’ Rights Act 2025
The first phase of the Renters’ Rights Act 2025 came into force on 1 May 2026 and applies to HMO landlords in England. The key changes are:
- section 21 no-fault evictions have ended, so you need a legal reason, known as a possession ground, to end a tenancy
- fixed terms have been replaced by rolling tenancies that tenants can end with two months’ notice
- rent can only be increased once a year, with at least two months’ notice
- you can’t take more than one month’s rent in advance or discriminate against tenants with children or those on benefits
Seek legal advice for your specific situation.
Energy Safety Responsibilities in HMOs
Your HMO landlord obligations include a legal duty to make sure all gas equipment and all fixed electrical installations such as wiring, sockets, light fittings and fuse boxes, as well as any electrical appliances provided by the landlord, such as cookers, kettles and fridges, are safely installed, maintained and inspected. HMO landlords must not unreasonably cause any occupier’s gas or electricity supply to be interrupted.
Getting your energy set-up wrong can expose you to overcharging claims, safety hazards and energy theft.
Metering and Energy Supply
In most HMOs, either the landlord pays the bills and the rent includes them, or the landlord installs a private sub-meter for each room and tenants pay the landlord for what they use.
If you charge tenants for energy, Ofgem’s maximum resale price rules mean you can’t charge more than you paid your supplier, including a fair share of standing charges. Overcharged tenants can recover the difference through the civil courts. What you pay depends on your own tariff, so it helps to understand the energy price cap.
Why HMOs Are at Higher Risk of Energy Theft
Where rent includes bills, tenants have little reason to tamper with the supply unless they are powering something like a cannabis farm. Bills-inclusive rent is also how some rogue landlords hide meter tampering, which is why we warn tenants that when a fixed or unusually low amount for bills is included in rent, it can be a red flag.
Sub-metered HMOs carry a different risk, because tenants pay for what they use. A tenant may tamper with their sub-meter or run appliances from sockets in shared areas, so the usage never registers against their room.
A smart meter on the main supply sends readings to your supplier automatically, but it won’t show what is happening on private sub-meters.
With a main meter, private sub-meters and communal supplies all in one building, gaps between what the property uses and what each room records can be hard to spot. Where meters sit in shared hallways or unlocked cupboards, anyone in the building can get to them.
Spotting and Reporting Energy Theft in Your HMO
Knowing who to report energy theft to is part of your HMO landlord responsibilities, and it depends on which meter is involved.
Tampering with the incoming supply or a supplier-registered meter that is not registered to an energy account in your name can be reported completely anonymously to Stay Energy Safe. If each room or bedsit has its own meter registered with an energy supplier, tampering with that meter can be reported anonymously to Stay Energy Safe too, although this set-up is more common in blocks of separate flats than in HMOs. If the energy account for the tampered meter is in your name, you will need to report this to your energy supplier so they can carry out any repair work.
As a landlord, you can also be a victim of HMO energy theft. A tenant may tamper with the private sub-meter you installed, or plug appliances into communal sockets so the usage never registers against their room. This is a matter between you and your tenant that neither we nor the supplier can resolve, and the What to Do section below explains your options.
Signs to Look for During Inspections
Look out for:
- broken seals, scorch marks or loose wiring on the main meter
- gas pipework that looks out of place, or rubber tubing
- sub-meters that are damaged or disconnected
- extension leads running from shared areas into individual rooms
- tenants refusing access to their rooms or the meter cupboard
- a main energy bill that rises sharply without matching usage on the sub-meters
See our meter tampering guide for the full list of signs.
Cannabis Farms in HMOs
Rental properties can appeal to cannabis farm criminals because of the anonymity they offer. Be wary of tenants who take a particular interest in the electricity supply, offer several months’ rent upfront in cash or change locks without telling you.
Never enter a suspected cannabis farm yourself. Report it to the police on 101, or 999 if there is immediate danger. Read our guide to cannabis farms here.
What to Do if You Discover Energy Theft
Don’t touch the meter, sub-meter or any wiring. If you smell gas, call the National Gas Emergency Service on 0800 111 999 immediately. If you notice sparks or a burning smell around the electricity meter, keep away and call 105.
If the incoming supply or a supplier-registered meter for a tenant’s room, bedsit or flat has been tampered with, and the account is in the tenant’s name, report it to Stay Energy Safe on 0800 023 2777 or through our simple online form. It’s free and 100% anonymous. If the energy account for the meter is in your name as the landlord, report it directly to your energy supplier.
If a tenant has tampered with a private sub-meter or bypassed it through communal sockets, Stay Energy Safe and your supplier can’t act. Use a qualified electrician or Gas Safe registered engineer to make it safe and replace the sub-meter, report the theft to the police and consider a small claims court claim to recover your costs.
Protecting Yourself as a HMO Landlord
Tenancy Agreement Clauses
Your tenancy agreement can explain how energy is charged, state that tenants must not interfere with meters, sub-meters or wiring, and give you the access for electricity safety checks and gas safety checks that the electricity and gas safety regulations require. With the Renters’ Rights Act changing how tenancies work, it can be a good idea to have a solicitor or landlord association check the wording.
Regular Inspections
Inspections let you check alarms, fire doors, meter cupboards, sub-meters and shared areas before small problems become dangerous. Give tenants at least 24 hours’ written notice, visit at a reasonable time and keep a dated record.
Smart Meters
All smart meters in Great Britain must meet minimum technical requirements, which include a defined set of tamper alerts. These are designed to flag signs of interference automatically to the supplier, so somebody can then physically inspect the meter if needed.
