As of 2025, the rules surrounding Houses in Multiple Occupation (HMO) in the UK have evolved considerably.
Staying compliant with the latest HMO regulations is essential for landlords who want to avoid fines and legal complications and ensure their tenants’ safety and well-being.
Whether you’re a seasoned landlord or just entering the rental market, understanding the current rules and how they impact your property management responsibilities is non-negotiable.
At London Estate Agency, we specialize in managing HMO properties and ensuring landlords remain compliant, stress-free, and profitable.
This comprehensive guide outlines everything you need to know about HMO rules in 2025 and why working with us is your best move forward.
What is an HMO in 2025?
An HMO (House in Multiple Occupations) refers to a property rented out by three or more people who are not from one household (e.g., a family) but share facilities like the bathroom and kitchen.
In 2025, the following criteria define an HMO:
At least three tenants occupy the property, forming more than one household.
Tenants share toilets, bathrooms, and kitchen facilities.
The property is used as their primary residence.
This definition remains unchanged, but enforcement and compliance requirements are more strictly observed now than ever.
Do You Need an HMO Licence in 2025?
Yes. Mandatory HMO licensing still applies to properties that are:
Rented to five or more people forming more than one household.
Tenants share facilities such as the kitchen or bathroom.
However, some local councils have expanded licensing to cover smaller HMOs (three or more tenants). Always check with your local authority or let our expert team handle your legwork.
Key Changes to HMO Rules in 2025
Increased Local Authority Inspections
With stricter regulations, local councils ramp up inspections on licensed and unlicensed HMOs. Landlords operating without the correct licence face fines of up to £30,000 per offence.
Fire Safety Compliance Updates
Under new fire safety regulations, landlords must:
Install interlinked smoke alarms in every room.
Provide a clear, documented fire risk assessment.
Ensure fire doors are installed and fully operational.
Our in-house team conducts full-fire compliance checks, giving you peace of mind and complete legal protection.
Minimum Room Size Enforcement
Each sleeping room must meet the following minimum sizes:
6.51 m² for a single adult.
10.22 m² for two adults.
4.64 m² for children under 10.
Failing to meet these minimum standards will result in enforcement notices or fines. Our property assessment service ensures your rooms meet or exceed these standards.
EPC Rating Requirements
From 2025, all HMO properties must have a minimum EPC rating of C. Suppose your property currently has an EPC rating of D or below.
In that case, you must carry out energy efficiency upgrades.
Our EPC upgrade service guarantees that your property complies with this rule while helping reduce tenant utility bills — a win-win.
Tenant Safety and Management Responsibilities
As an HMO landlord, your legal duties include:
Gas Safety Certificate (updated yearly)
Electrical Installation Condition Report (EICR) every 5 years
Installation of Carbon Monoxide Detectors
Ensuring adequate waste disposal arrangements
Providing written tenancy agreements
At London Estate Agency, we handle all safety checks and documentation, giving you hassle-free compliance and reducing risk.
HMO Licensing Cost in 2025
Licensing costs vary by borough but typically range from £500 to £1,300 depending on property size and location.
Renewals are required every 5 years, and the application process can be time-consuming.
Let our licence management team handle your application and renewal so you never miss a deadline.
Penalties for Non-Compliance

Civil penalties of up to £30,000
