HMO Licensing in the UK: What Landlords Need to Know in 2025

Written by Steve Doran | Jun 24, 2025 2:51:00 PM

Intro:

Thinking of running an HMO in 2025? Before you jump in, there’s one thing you absolutely need sorted - your licence.

Getting this wrong isn’t just a paperwork issue. It could cost you thousands in fines, stop your property from generating income, or even land you in court.

Here’s what you need to know to get licensed fast, stay compliant, and keep cash flowing.

 

What Is an HMO and When Do You Need a Licence?

An HMO (House in Multiple Occupation) is any property rented out to three or more unrelated tenants who share facilities like a bathroom or kitchen.

In most areas, you’ll need an HMO licence if:

  • Your property is let to 5 or more people

  • Tenants share basic amenities (kitchen/bathroom)

  • It's their main home

Some councils also require a licence for smaller HMOs under additional licensing schemes, so always check with your local authority.

 

How to Get an HMO Licence

The process is usually done through your council’s website. Here’s what they typically ask for:

  1. Proof of ownership or management

  2. Floor plan with room sizes

  3. Fire safety systems in place (alarms, extinguishers, etc.)

  4. Gas and electrical safety certificates

  5. A fit and proper person declaration

Expect to pay anywhere between £500 and £1,500 depending on your local council.

How Long Does It Take?

Most councils aim to issue HMO licences within 8 weeks, but delays are common. You can’t legally operate until your licence is approved - so apply early.

What Happens if You Don’t Get Licensed?

Operating without a licence is a criminal offence. Councils can issue:

  • Fines up to £30,000 (per offence)

  • Rent repayment orders (they can claim up to 12 months' rent)

  • A criminal record in some cases

It’s not worth the risk.

New Rules to Know in 2025

A few councils are tightening rules this year. Some key updates:

  • Stricter room size minimums

  • Energy efficiency targets for licensable properties

  • Tighter checks on fire doors and alarms

Make sure your property meets the latest standards before applying.
