Compliance Checklist

that your rental property is compliant
If you own a buy-to-let property in the Peterborough area, you might be considering letting it as a house in multiple occupation (HMO). The benefits of HMOs for landlords include a potentially higher rental income, plus spreading the risks of non-payment – as each tenant pays for their room separately.

However, there are some additional rules and regulations to consider with HMOs, including applying for an HMO licence from your local authority. So, if you have a rental property in areas such as Rushden or Kettering, you will need to check the rules for the North Northamptonshire Council, or whichever council covers the area your property is in.
There are also different gas and fire safety regulations because unrelated people sharing a home may pose more significant health and safety risks. Failing to comply could lead to prosecution, fines and losing your licence, so it’s essential to understand HMO regulations from the start.
If you’re considering letting a house in multiple occupation, read on for everything you should know about HMO regulation and the law.
In Peterborough, a property is classed as a house in multiple occupation if at least three tenants live there, forming more than one household and if toilets, bathrooms or kitchen facilities are shared. The Housing Act 2004 defines a household as either a single person or members of the same family. This includes married or cohabiting couples, foster families and individuals with a live-in carer.
Here are some examples to help you define how many households live in a property:

Following the Housing Act 2004, you must have a mandatory HMO licence if your property is a large HMO. Even if your property is smaller, you may still need an additional licence, depending on your area.
You must obtain a mandatory licence if your property is a large HMO. A property is considered a large HMO if all the following apply:
Even if your property is rented to fewer people, you may still need a licence, depending on regulations set by your local authority. Additional HMO licensing is used by local councils to require licences for houses in multiple occupation that do not meet the mandatory licensing requirements.

If you need an HMO licence, you must pay a fee and supply certain information, such as your property’s floor plan and gas safety certificate. You must also demonstrate that you are ‘a fit and proper person’ to be the licence holder. This means showing that you are of good character and will not pose a risk to the welfare of your tenants.
Just like council tax rates, licence fees vary depending on the local authority, and the fees are subject to change so you should check the latest fees for the local authority that your HMO property is in.
Landlords don’t usually need permission to convert a Class C3 property (family home) into a small HMO housing three to six unrelated occupants. But you must seek permission to convert rental properties into large HMOs for seven or more people. You should contact your local council if you are not sure whether you require planning permission for work on the property.

Under the Management of Houses in Multiple Occupation (England) Regulations 2006, the responsibilities of HMO managers or landlords include:
Since 2018, regulations on HMO minimum room sizes used for sleeping accommodation have been in force. These stipulate the following minimum bedroom sizes:
Other regulations stipulate the number of bathrooms and toilets that must be provided depending on the number of people living in the property. Peterborough Council have minimum standards for natural light and ventilation according to the room size.
All residential landlords have legal duties where gas safety is concerned. The property’s gas supply and all gas appliances must be fitted, repaired and checked annually by a Gas Safe-registered engineer. This covers appliances such as cookers, gas fires, boilers, water heaters and the property’s gas pipework.
Under the Housing Act 2004 and houses in multiple occupation management regulations, landlords must be able to provide the gas certificate to the local authority on request. If your HMO needs a licence, you must also provide your gas certificate as part of your application and submit an updated copy each year. Read more on the gov.uk website.
HMOs are considered a higher fire risk than standard buy-to-lets, so they have more stringent regulations. You should always check your local authority’s website as HMO fire safety requirements vary by council area. Other conditions apply across England.
All landlords must:
Landlords must ensure the safety of all electrical wiring and plug sockets. You must arrange for a qualified electrician to conduct an inspection every 5 years, supplemented by regular basic safety checks. Your electrician should produce an Electrical Installation Condition Report (EICR), which you should give to each new tenant before they move in.
If you provide your tenants with any electrical appliances, you must ensure they are safe for the tenant to use. The best way to do this is by ensuring all provided electrical items are subject to an annual portable appliance test (PAT). Peterborough Council requires HMO landlords to carry out PAT testing and complete a declaration confirming which products have been tested, details of both passes and fails, re-test dates, and details of the person or organisation who performed the test.
An EPC (Energy Performance Certificate) is required for nearly all types of rental properties, including HMOs. Self-contained flats require their own EPC, but bedsit rooms within a house of multiple occupation do not require an individual EPC but there must be an EPC for the building.
Find out more in our guide on electrical safety obligations for landlords.
You are responsible for repairs to the structure and exterior of the house, including:
HMO properties must also comply with ventilation requirements, such as:
Being an HMO landlord isn’t all that different from being any other type. You still need to follow many of the rules associated with renting out property, which include:

You must provide your tenants with the following:
Landlords must ensure that the property is fit to live in throughout the tenancy, in compliance with the Housing Health and Safety Rating System (HHSRS). The HHSRS is a list of 29 hazards that are rated to identify any issues that would mean that the property is not fit for human habitation.
Issues which might make the property unfit for habitation include:
The fit for human habitation legislation applies to all sleeping accommodations and communal areas of your HMO.
If the tenant believes you haven’t fulfilled your responsibilities, they can take you to court.
Legionella is the bacteria which causes legionnaire’s disease, a potentially fatal form of pneumonia. HMOs are thought to pose a greater risk of legionella compared to single lets. You are obliged by law to carry out annual checks for legionnaire’s disease and tests between tenancies and take action if necessary. You need to keep records for five years. Find out more on the Health and Safety Executive website.
The General Data Protection Regulations (GDPR) were introduced across Europe in 2018 to give people more control over their data. As a landlord who handles tenants’ data, you are classified by law as a data controller. As such, you are responsible for managing your tenants’ personal information appropriately and lawfully. Read more about GDPR on the government website.
The Tenant Fees Act 2019 prevents letting agents and landlords in England from charging all tenants, including those in HMOs, specific fees. These include referencing fees, inventory costs or charges for professional end-of-tenancy cleaning. Tenancy deposits must also be capped at five weeks’ rent if the rent is less than £50k per year or six weeks’ rent where the total annual rent is £50k or above.
Tenants can complain to the council if they think you are not meeting your HMO landlord responsibilities.
The council can assess any hazards in the HMO and take action against landlords whose properties are unsafe or fit to live in. This could involve prosecution, revoking your licence or, in extreme cases, the council taking over management of the property.
